If you are familiar with electronic devices, kindly jump to the bottom part for each connection methods. In case you are new to monitors setup, read through the definition part will help you better understand.

Interface, Port and Protocal

Before talking about connections, let's make it clear for definiton of interface, port, and protocal. Although they seems very similar, each one has it's own meaning. For example, when we say Thunderbolt 3, it refers to a Thunderbolt 3 interface with USB Type-C port and Thunderbolt 3 protocal. And when we say Thunderbolt 2, it refers to a Thunderbolt 2 interface with Mini Displayport (MDP or Mini DP) and Thunderbolt 2 protocal. 

Interface = Port + Protocal

· Port is the physical identical, the shape of the interface, like USB-C port, USB-A port.

· Protocal is the agreement of the interface, define the ways it transfer the data and what it can transfer, like Thunderbolt 2 or USB 3.0

Female Port and Male Port

Besides, when we say port, it also has two physical type, one is Female Port, another is Male Port. Female port is commonly find on devices, like HDMI port on your laptop or TV. While Male port is use for cables, like HDMI cable to connect your laptop to the TV. To make the guiding with less confusing, we use Port for Female Port and Connecter for Male Port.

· Port is a Female Port on devices like laptop, TV and portable monitor.

· Connector is a Male Port on cables, like USB-C cable and HDMI cable.

For a cable, there should be two or more connector on both ends, so the full name of a cable should including both of the connectors, like USB-C to USB-C cable, or shorten to C-C cable. In common sense, a Type-C cable will refer to a USB-A to USB-C cable, a USB cable will known as a USB-A to micro USB cable. In help center, will include the two connector to avoid any misunderstanding.

Connection and Signal

Therefore, connection is using a cable with two connector to connect two devices, each has a female port, and ensuring the data can go smoothly from device A to device B. As we are talking about monitor and screen display, the data tramsit is mainly refers to Video & Audio Signal. 

All consumer electroic can not leave without power or battery, so to ensure the data transmit, there should be power supply, whether from a charger socket, or from device A to device B, or B to A, we call it Power Signal.

Last, in case you need touch control, the cable should also be able to transfer Touch Signal. That means to make a portable monitor work, below signals are requested:

· Video & Audio Signal

· Power Signal

· Touch Signal (Optional)

USB-C Port on Laptop

Thanks to USB4 and Thunderbolt 3, we can use one USB-C cable to connect from any qualify laptop or PC to a GEEKPORTER portable monitor. When we say qualify, we means that the laptop or PC is clearly stated that it has USB4 or Thunderbolt 3 or later. 

However, when it comes to USB Type-C 3.0 port, it's not always meet the requirement of Full Feature, whether for laptop or smartphone. This is the most confusing part because many devices are now upgrade to USB Type-C port but few of them stated what protocal does it include. 

For smartphone, USB-C port should have PD Power Delivery because it is the only charging port. But few of them has DisplayPort to output video signal. Similar case for laptop for fast PD charging but neither video output nor USB 3.0 for data transmit. For your better understanding, we draw out a table.

InterfaceSignalPortProtocalVideo & AudioPowerTouchThunderbolt 3 & 4Thunderbolt 3 & 4✅✅✅USB4USB4✅✅✅Full Feature USB Type-C 3.0USB 3.0❌❌✅DisplayPort 1.4✅❌❌PD Power Delivery❌✅❌HDMIHDMI 1.4 & 2.0✅❌❌Mini HDMIHDMI 1.4 & 2.0✅❌❌Mini DisplayPortThunderbot 1 & 2✅❌❌DVI/✅❌❌VGA/✅❌❌

Therefore, to use one USB-C cable setup, make sure your laptop or device has either USB4, Thunderbot 3 or later, or Full Feature USB Type-c. A Full Feature USB Type-C port should include three protocals:

• DisplayPort 1.4 for video & audio signal transmit
• PD Power Delivery for power signal supply
• USB 3.0 for touch signal

USB-C Port on Monitor

Now that you make sure your have a Full Feature Type-C port, you can easily use the USB-C to USB-C cable connect from your laptop to our monitor. As uperfect monitor is made for on-the-go, you can always find a full feature Type-C port on it. 

However, there are two USB-C port on GEEKPORTER monitor, one is for connecting laptop, another is for power supply. You can indentify them with the symbol next to it.

USB-C to USB-C Cable

Not only connection ports need to meet the Full Feature standard, but also the cables require the same feature. All USB-C to USB-C cable included in the package is USB 3.1 Gen 1 which support Full Feature Type-C. When you need to replace the original USB-C cable to your own, make sure your cable can meet the same feature.

It's quite easy to understand connection method besides USB-C, as you can see in the blow table, all ports only support one signal type, Video & Audio, which means you need to power up the monitor when using below connection ports:

InterfaceSignalPortProtocalVideo & AudioPowerTouchHDMIHDMI 1.4 & 2.0✅❌❌Mini HDMIHDMI 1.4 & 2.0✅❌❌Mini DisplayPortThunderbot 1 & 2✅❌❌DVI/✅❌❌VGA/✅❌❌

HDMI

More and more GEEKPORTER monitors use Mini HDMI than HDMI due to it's slim design. Some model still retain HDMI because the connection is more strong and stable. No matter which model you purchase, you can always find the corresponding HDMI cable:

• HDMI port: HDMI to HDMI cable
• mini HDMI port: HDMI to mini HDMI cable

After connecting HDMI cable, power up the monitor with the PD charger come along, then all things done.

Mini DisplayPort

Several Macbook and Surface laptop use mini DP port. If you are using these models, kindly use a mini DP male to HDMI female adapter. After that, just folow above HDMI cable connection step.

DVI & VGA

In case you are trying to upgrade your old PC or other devices with a GEEKPORTER monitor but has only DVI or VGA port, you have two options:

1. Buy the monitor with HDMI port, convert the DVI or VGA port to HDMI using adapter. Make sure that the adapter can transfer from DVI or VGA to HDMI. This is important because some adapters only support one-way convert HDMI to DVI or VGA. Following that, refer to above HDMI cable connection process.
2. Buy UProject Series monitor which has VGA port build-in. However, you need to bring your own VGA cable as it is not included in the package.

If you purchase a touch monitor and need more help for touch control setup, check this article for details.

Here are the ways to setup GEEKPORTER monitor wirelessly:

Wireless Miracast Dongle

Mirroring all devices with miracast or WIFI connection, including laptops, smartphones and computers, to TVs and portable monitors. Easy setup with no QR code scanning, no APP downloading, and even no devices trusted needed (IOS device).

Model UFree V

Thanks to the advent of UFree technology, we designed the Model V, the first wireless high-definition display. Based on 5G millimeter wave transmission, UFree has enhanced anti-interference performance, making transmission more stable and reducing transmission loss. More stable than WiFi and Bluetooth transmission, it will be an inevitable choice for the next generation of wireless display.

When using DP to USB-C cable

Some Delta model does not support DP to USB-C cables

Laptops

USB-C to USB-C

If connecting to a laptop using USB-C with one cable, ensure that you have a Thunderbolt 3 / 4, or Full Feature USB-C (3.1 or later) port with DP 1.4 and PD power delivery. Some laptops use USB-C only for high-speed charging (Power Delivery--PD) but no video output (DisplayPort--DP), check with your laptop provider for details or check this site www.epey.com for reference. You might need Google to help you translate because it's a Turkish site. 

Search your model and find Connection & Interfaces in the specification. If you can find USB 3.0, DisplayPort 1.4, and Power Delivery, then your laptop should be compatible.

As USB 3.0 is renamed several times, you might be confused when it says USB 3.2 Gen 1. Here is a chart to help you understand better and make sure you have at least USB 3.0.

Most modern portable monitors come with a USB-C to USB-C cable. Make sure to plug it into the right Type-C port on the monitor, as some ports might only provide power and are labeled as PD ports.

If you’ve connected everything correctly and your laptop supports Thunderbolt 3.0 or newer, but the power indicator on the portable monitor is green and you still see the "No Signal" message, it's time to  check for other issues.

Mini HDMI, HDMI, or DisplayPort

If your laptop doesn’t have any extra USB-C ports to connect to the monitor, or if the USB-C connection isn’t working, you can try using the Mini HDMI, HDMI, or mini DisplayPort on your laptop, as these can also transmit video signals. The port you choose will depend on your monitor. If you still see 'No Signal' after connecting with any of these ports, you can try to use a new cable. When that doesn’t help, ask the retailer for help.

Computers

Many users are using the second external screen with computers or PCs. If the device is not yet upgraded to an HDMI port for video output, they need to convert VGA or DVI to HDMI. If that's the case, ensure your adapter can support VGA to HDMI compatibility because some adapters offer only one-way connectivity, HDMI to VGA. Besides, You should buy the "VGA to HDMI Converter with Audio", to avoid the display showing only video without any sound. However, since 2008, most desktop consoles and graphics cards have supported HDMI ports. Therefore, only a small number of people need to consider purchasing the aforementioned accessories in order to connect the monitor.

The reason for converting VGA or DVI to HDMI is that the first two only support video transmission, while HDMI also carries audio. Plus, HDMI can handle 4K high-definition video. The table below highlights the key differences between these three interfaces.

Gaming Consoles

The Nintendo Switch, Steam Deck, and ROG Ally, utilize USB-C, providing great versatility for connecting to monitors. In addition, Nintendo Switch also use HDMI when docked. You may also face the "No Signal" message when trying to connect your portable screen display to a Nintendo Switch console via a USB-C to USB-C cable. In such a case, ensure the monitor is powered via the Switch charger rather than the monitor's charger. If you want a more stable connection, you may use the HDMI port of the Switch dock. For best results, ensure all cables are in good condition and that the correct input source is selected on your monitor. 

Besides  the Nintendo Switch, the PlayStation 4 and 5, Xbox One and Series X/S (when docked) also use HDMI.

USB-C Port Compatibility

Most modern smartphones have USB-C ports, but few of them have video output functions. Phone brands that have upgraded the Type-C port to Full Feature function are mostly found in the Samsung Galaxy series, iPhone 15 series, and Honor Magic series. To confirm if you phone is in the list, ask your phone provider or check this site www.epey.com for reference.

Search your model and and look into Other Links in specification page, confirm your phone has USB 3.0 and DisplayPort. Besides, make sure the OS version is Android 10 or later, than your mobile phone should be compatible.

Desktop Mode

Now we can confirm that your phone can mirror to the monitor. However, when it comes to Desktop Mode, not all mobile brands build the lapdock operation system like Samsung Dex. You can click on this table (List of Smartphones with DisplayPort Alt Mode) to know more about this topic. 

You can also go to the website www.epey.com, change the language to what you need, and filter for phones that have DisplayPort, Android 10 or above, and USB 3.0 or higher. Feel free to check out the screenshot below for reference.

3 IN 1 HDMI Adapter Cable

If your phone is not in the list, use this cable can also mirror your phone to the monitor. But keep in mind that this method is only for mirroring your screen, so it won't let you extend it. 

You can connect your smartphone to the monitor by following these steps.

1. Connect the monitor to power (if not battery-powered).
2. Use the 3-in-1 adapter to connect your phone.
3. Power the adapter via USB.
4. Android: scan the QR code to pair. (iPhones connect directly.)
5. The phone's display should now appear on the monitor.

After scanning the QR code and downloading the mirroring software on your Android device, you may also need to follow the instructions in the image below. For more information on how to do this, check out Method 2 in this article.

Insufficient Power Supply

There is a limit power output for smartphones. For moniotrs with larger screen size like 22 inche, higher resolution like 4K or refresh rate, it always need more power input. Power up the monitor with the power socket include in the package or use a PD power bank.  To charge your portable monitor, choose a power bank that supports the PD Protocol Type. Lower-wattage banks may only support PD 1.0 or 2.0, which might not be enough. Check the table for outputs and protocols. Select a bank with a rating equal to or higher than your monitor's charger, such as 65W or more if your charger is 65W.

Game consoles can connect to portable monitors using HDMI and USB-C ports, but not all of them support both options. This means there are some technical limitations when hooking up your portable monitor. If a console's HDMI port is HDMI 1.4 or higher, it should work fine. Some consoles even need a dock for HDMI connections. And while a few can cast directly using USB-C to USB-C, the USB-C port needs to support DisplayPort Alt Mode for that to work.

Generic Troubleshooting

HDMI Troubeshooting

Check the Protocols of HDMI

As mentioned earlier, HDMI should be at least version 1.4. You can go to the console's website to check if the HDMI port of the product meets HDMI version 1.4 or above. Otherwise, all of the subsequent checks will be in vain.

Check the HDMI Cable and Ports Physically

Remove the HDMI cable from both the gaming console and the monitor, and use a flashlight to check inside both ports for any bent pins. Meeting the bent pins in the HDMI port, you might see a "No Signal" message or a blank screen. In this case, unplug the monitor or gaming console from the wall and gently push the bent pins back into place using a flat screwdriver.

Try Switching the ends of the HDMI Cable

This method is the experience of many users. This method helps fix problems with a loose HDMI connection.

Try a Different HDMI Cable

HDMI cables can sometimes have issues, so if you have another one available, consider swapping it out with the current cable.

USB-C Problem Solving

Check the Protocols of USB-C

Connect your console to the display using a USB connection. You should make sure the USB port is at least USB-C 2.0 or 3.2 Gen 2 and that it supports DisplayPort Alt Mode.

Other Situations

Besides checking for incompatible port protocols, you can also try the following troubleshooting methods.

1. The USB connection cable might not be plugged in all the way, or it could be loose or not making a good connection.
2. Most modern portable monitors usually come with a USB-C to USB-C cable. Make sure to connect it to the right Type-C port on the monitor, as some ports are designated for power only and are labeled as PD ports.

Specific Troubleshooting

PlayStation 4

Press and hold the power button on your PS4 for seven seconds until you hear a second beep. If you see "No Signal," "Weak Signal," or a blank screen, check your resolution settings.

1. Press and hold the power button again until the PS4 restarts, lifting your finger after the second beep.
2. Use a USB cable to connect your controller to the PS4.
3. Press the PS4 button on the controller to bring up the menu.
4. Select "Change Resolution" (the second option) and press X.
5. Press X again to restart your PS4.
6. Select a resolution, keeping it compatible with your monitor (e.g. 720p for a 720p monitor).
7. Press X to confirm. You should now be able to play your PS4.

Nintendo Switch

When you dock your Nintendo Switch, the LCD screen turns off, and what you were playing shows up on the monitor.

If you see a white screen or no image in monitor mode, try these steps.

1. Unplug all cables from the dock.
2. Disconnect the power adapter from the console and the outlet for about 30 seconds. Make sure you’re using the original Nintendo Switch power adapter (model HAC-002) and check for any damage.
3. Take the Switch out of the dock, plug the power adapter back into it, and connect it to the outlet.
4. Make sure your console is updated. If it is, hold the power button for three seconds to restart it, then go to "Power Options" and choose "Restart."
5. Check that you’re using the original Nintendo Switch dock (model HAC-007). If you’re using a third-party dock, try switching to the original.
6. Connect the power adapter to the dock and plug it directly into the outlet. Then, connect the HDMI cable from the dock to the monitor.
7. Turn on the monitor and dock your console, ensuring it faces the same direction as the front of the dock.
8. If the LED on the dock lights up but you still don’t see anything, try these:

Steam deck

Updating Your Dock's Firmware

To make sure your dock is running the latest firmware, you might want to try a full reset. Here's how to do it.

1. Plug the power cable and your Deck into the dock.
2. Restart your Deck.
3. Disconnect both the Deck and the power cable from the dock.
4. Wait for about 10 seconds, then plug them back in.

This should initiate the firmware update. If it doesn't, reconnect the Deck and the power cable to the dock. Then, unplug the power cable from the dock, which might help initiate the update.

Compatibility with Third-Party Docks and Hubs

Most compliant USB-C hubs and docks work great with the Steam Deck. Thunderbolt and DisplayLink docks may also work but they aren't officially supported.

For powering the Steam Deck, make sure your dock or hub supports USB-C Power Delivery (PD). Some docks might reserve a bit of power for other devices, which could trigger a "charger speed too slow" warning.

Monitor Settings Tips

Avoid using passive cable adapters like DisplayPort™ to HDMI as they might cause issues. Instead, stick with active cables or adapters.

Also, when you connect a cable to a monitor, your Deck's screen will go black, which is normal in "game mode." Currently, the only way to enable dual or multiple displays is by rebooting into desktop mode.

If your Deck doesn't go black when connecting an external monitor, try resetting it (see below). If it still doesn't detect the monitor, unplug and replug the cable, try a different input port, or test with a new cable since these can sometimes fail.

You can also try another source or dock like a laptop or tablet with a monitor output.

If you have multiple monitor cables, try those as well. Just remember a cable that works in one setup might not work in another due to differences in data rates, color depth, resolution, and refresh rates. This is especially true for high-resolution or high-refresh-rate setups. It's best to use compliant DP1.4 and HDMI2.0+ cables for the best compatibility.

In the Steam Deck UI, you can change the resolution and refresh rate by going to "Steam" > "Display." If lower settings display correctly, your dock, cable, or monitor might not support the mode you're trying to use.

Resetting Your Dock

If you think your dock needs a reset, just unplug the Deck and the dock completely including the power and display cables, and then plug everything back in. Keep in mind that even if you unplug the dock's power, it will still draw power from the Steam Deck, so make sure to disconnect both for a full reset.

ROG Ally

The dock connects the ROG Ally to the monitor, but if you run into a black screen when the HDMI cable is plugged in, here are two ways to fix it.

1. Open Device Manager and uninstall the external monitor. Restart your device, but if the display is still blank, uninstall the graphics card and restart again. This should help the external display show up.
2. Press M1 + X to enable mirrored display, then turn off mirroring and turn it back on. If it doesn’t work right away, try pressing those buttons a few more times.

Extend or Duplicate screen for Windows

Before adjusting the settings for your external displays, ensure that everything is connected correctly. Here are some steps you can follow:

1. Make sure your cables (HDMI/USB-C) are securely connected to your PC or dock.
2. Check for Windows updates. To do this, click on Start, then search for Settings. 

• Windows 11: Select Settings > Windows Update > Check for updates. 
• Windows 10: Select Settings > > Update & Security> Windows Update > Check for updates. 

Here’s a quick guide to set up multiple displays (Windows 11):

Detect Your Displays

If a connected display isn't showing, click Start, search for Settings, and go to System > Display > Multiple displays > Detect.

For Windows 10: select Start  > Settings  > System > Display > Rearrange your displays, then select Detect. 

Identify Your Displays

Click Identify in the Display settings to see which number corresponds to each screen.

Arrange Your Displays

Drag and rearrange the displays in the settings to match your physical setup. Click Apply when done.

Choose Your Display Option

Press the Windows logo key + P and select one of the following:

• PC screen only: Use one display.
• Duplicate: Mirror all displays.
• Extend: Spread your desktop across screens.
• Second screen only: Use the second display exclusively.

Adjust Display Options

In Settings > System > Display, you can modify resolution and orientation settings as needed.

Extend or Mirror screen for Mac OS

1. On your Mac, open Apple menu > System Settings, then select Displays. 

2. Click your display's name, then choose an option from the “Use as” menu. 

Note: If you have a Mac laptop or iMac, you'll need to connect an external display to access these options. For devices without a built-in display, like a Mac mini or Mac Studio, you must connect multiple displays to see these settings.

3. To mirror displays, set all to extended desktop, hold the Option key, and drag one display icon onto another.

How to distinguish between 1, 2 and 3 screens

Click on Start, then go to System, and select Settings. From there, choose Extended Mode and click on Identify. At this point, all three monitors will show big numbers to let you know which screen is which.

The scaling between different monitors

If you find yourself in any of these situations.

1. You've just set up dual monitors, but they have different resolutions.
2. You're using a main screen alongside a portable screen, and their sizes are quite different.
3. Dragging windows between screens feels awkward because of the scaling.

Then keep reading! We'll help you tackle those frustrating window scaling issues caused by differences in resolution and size.

1. Misalignment of Display Windows with the Same Size but Different Resolutions

Let's look at a dual-screen setup with a 27-inch 4K monitor and a 1080P screen. 

Here's how to align them properly.

1. Open the NVIDIA Control Panel and click on "Change Resolution".
2. Select your 1080P secondary screen.
3. Click on "Customize" to set a custom resolution.
4. Set the horizontal pixels to 3840 and the vertical pixels to 2160.
5. Click "Test", then "OK" to save the new virtual resolution for your 1080P screen.
6. Finally, go to your computer's "Display Settings" and change the resolution of the secondary screen to 3840x2160. 

This will give you a seamless cross-screen experience without any scaling issues.

2. Different Sizes and Resolutions but Proportionally Scaled Monitors

Now, let's tackle a setup with a 27-inch 4K monitor and a 14-inch 2K monitor. 

In this case, we need a quick calculation.

1. First, we need to calculate the PPI (Pixels Per Inch) for both screens using the formula:

PPI=√(X²+ Y²) / Z

X is the horizontal pixel count, Y is the vertical pixel count, and Z is the screen size.

2. For the 27-inch 4K (3840x2160), the PPI is approximately 163.17.

For the 14-inch 2K (2560x1440), the PPI is around 209.8.

3. Next, divide the PPI of the main screen by that of the secondary screen:

163.17/209.8≈0.7777

4. Now, calculate the resolution you need for the secondary screen:

• Horizontal:  2560×0.7777≈1991
• Vertical:  1440×0.7777≈1120

5. Return to the NVIDIA Control Panel, set the secondary screen's resolution to 1991x1120, and adjust your display settings. This will ensure your windows drag smoothly across both screens without any noticeable scaling.

By following these steps, you'll have a perfectly aligned multi-monitor setup!

Why is my 144Hz/120Hz/100Hz monitor stuck at 60Hz? Is this problem caused by hardware or software? What should I do to fix it? This article will clear up your doubts and provide you with the perfect solution.

Why Can't My Monitor Run at 144Hz/120Hz/100Hz?

The Reasons

If your monitor isn't reaching high refresh rates like 144H / 120Hz / 100Hz, there could be a few reasons for this:

• System incompatibility
• Incorrect cables not being used
• Monitor settings not adjusted to the required resolution
• Drivers not updated
• Portable monitor lacking external power

What Should I Do?

Check System Compatibility

First, ensure your device like a laptop, game console, etc., supports 2K resolution and has the necessary ports to connect to the display. You can check the product's official website or manual to see if it has a 2k resolution. 

Generally speaking, many computers with integrated graphics can reach 2K at 60Hz/100Hz. But, to achieve resolutions above 2K at 120Hz, a computer with a dedicated graphics card is generally required. You can check if your computer has a dedicated graphics card by following these steps.

1. Right-click on the desktop.
2. Select Display settings or Display adapter properties.
3. Open Device Manager.
4. Expand Display adapters.
5. Check for the professional graphics card name.

You can check your HDMI and USB-C ports for compliance. 

1. HDMI : supports up to 2560x1440 at 144Hz and 2560x1600 at 120Hz
2. USB-C: goes up to 2560x1600 at 144Hz

Use the Right Cables

1. Use high-quality cables like DisplayPort or HDMI 2.0 to connect the monitor to your device, ensuring proper transmission of high-resolution and high-refresh-rate signals. 
2. The cables with the monitor meet the highest output requirements, and you should not arbitrarily change them.

Adjust Display Settings

1. Some devices might not automatically set the optimal resolution and refresh rate. You may need to manually set the display resolution to 2K (2560x1600) and the refresh rate to 144Hz for the smoothest experience. 
2. Enable Adaptive Sync (if available): If your monitor and device support technologies like AMD FreeSync, enable them to reduce screen tearing and enhance gaming performance. 
3. FreeSync typically requires settings above 60Hz. If set to 30Hz, display issues may occur.

Keep Drivers Updated

Install your device's latest graphics card drivers to ensure compatibility and optimal performance with the 2K 144Hz display.

Provide Sufficient Power

Some portable monitors may require an external power source for optimal performance. Please ensure the monitor is connected to a power outlet or the battery is adequately charged.

Why Can't I Select 120Hz or 2K/1440p When Connecting Xbox/PS4/PS5 to My Monitor?

The Reasons

Because monitors with a refresh rate above 120Hz must load games running at 120Hz or higher to display that refresh rate when connected to PS5 or Xbox Series X/S. This is how to enable 120Hz. It's due to the console's settings.

How to Set Refresh Rate to 144HZ or 2K/1440p?

Steps to Set 120Hz:

1. On your console, go to Home.
2. Navigate to Settings → General → TV & Display Options.
3. Select Video Fidelity and Overscan.
4. Under Display, set it to Auto-Detect.
5. Go back to Display Options and choose 120Hz for the refresh rate.

Note: If the game doesn’t support 120Hz, the console will default to 60Hz, even if the monitor is capable of higher refresh rates (especially on Xbox Series X/S).

Steps to Set 2K/1440p:

1. Go to the console's Home screen.
2. Open Settings → General → TV & Display Options.
3. Navigate to Video Fidelity and Overscan.
4. Under Display, set to Auto-Detect.
5. Go back to Display Options and select 1440p.

These settings allow the monitor to display the selected refresh rate and resolution, provided the console and game support them.

The Reason

1. The monitor is not connected to a power source.
2. The confirmation button was not pressed after setting the brightness.
3. The low-power mode is not disabled.
4. HDR is not turned off on the MacBook.

What Should I Do?

Monitor Connection to Power 

Regardless of whether the monitor uses HDMI or USB-C for signal transmission, the PD interface of the monitor must be connected to a power source when adjusting settings. Otherwise, adjustments may fail, especially with high-power monitors. For example, with monitors over 2K, if you connect the laptop only via a USB-C cable without an additional power source, your brightness settings may not be saved. This is because the monitor is set to prioritize normal display functionality when USB-C power is insufficient to prevent a black screen.

Press the Confirm Button After Setting the Menu 

If you adjust the brightness but forget to save it, your settings will not be saved automatically. Therefore, you need to press the confirm button for the adjustments to take effect.

Disable Low Power Mode

For monitors with a low power sub-menu, you need to enter the menu and disable low power mode before adjusting the brightness to successfully save your settings.

Disable HDR on MacBook 

Sometimes, a MacBook may experience low brightness due to HDR being automatically enabled. You can try turning off the HDR on your laptop and then turning it back on. The steps to turn off HDR on a MacBook are:

1. Click the Apple icon in the top left corner.
2. Select System Settings (or System Preferences).
3. Go to Displays.
4. If your monitor supports HDR, uncheck the HDR option.

However, after turning off HDR, some users might run into new issues and find themselves asking, "Why is my monitor so bright when HDR is off?" You could be facing one of several scenarios. But don't worry, we’ll share some helpful solutions to get things back on track.

• Brightness Settings Too High

Your brightness might be set excessively high, especially if it was adjusted for HDR. Reduce brightness in the monitor's on-screen menu (OSD).

• Automatic Brightness Adjustments

MacOS may automatically adjust brightness, keeping it high even when HDR is off. You can click on System Preferences > Displays, and disable the “Automatically adjust brightness” option.

• High Contrast Settings

Elevated contrast and gamma settings can affect perceived brightness. You can adjust contrast ettings in your monitor's menu.

Why Do Colors Look Different on Monitors and a Connected Device?

If you notice color differences between your monitor and your computer’s built-in display, don’t worry. This happens because each display uses different panels with varying color gamuts, color temperatures, brightness levels, and contrast ratios. 

Your monitor will already be calibrated to its optimal settings when you get it. However, you can still adjust the brightness and color temperature based on your environment and personal preferences. Alternatively, try manually calibrating the monitor’s colors to minimize color discrepancies without a color calibrator.

What Should I Do?

When there is a noticeable color discrepancy between your laptop and monitor, you can use your eyes as a reference and manually adjust the color temperature and RGB settings to reduce the color discrepancy with your laptop.

The easiest way to align colors is by comparing the same desktop wallpaper on both screens and tweaking the settings bit by bit. Without a professional color calibrator, though, you'll need to rely on what looks comfortable to you. Achieving perfect color matching can be challenging since the color gamuts of laptops and monitors are usually different. For example, if your laptop uses DCI-P3 and your monitor only covers 72% of NTSC, the monitor's smaller gamut limits how accurately it can display certain colors. Even so, with some trial and error, you can follow basic color adjustment principles to get a closer match that works for your setup.

Adjusting the Color Temperature

The human eye is sensitive to color temperature. At higher temperatures (>6500K), images appear bluish and cool, while lower temperatures (<6500K) give a reddish or yellowish warm tone. Setting the temperature to 6500K makes whites look clean and natural, avoiding a blue or yellow cast.

Adjusting Contrast

Low contrast makes colors look dull, so increasing it helps them pop. Brighter screens enhance color vibrancy, but too much brightness can wash out colors. Keeping brightness at 50-70% ensures a good balance.

Choose a Stable Lighting Environment

When calibrating in a dark environment, colors often appear more saturated, making calibration in a stable lighting environment more reliable. It is advisable to use neutral or natural light sources (white light) and to avoid colored ambient lighting (such as warm yellow lights).

Choose a Professional Color Calibration Chart

You can download the following images or simply scroll through the article page. Open the same image on both the laptop and the monitor for color comparison. And then adjust the monitor's  RGB, reducing the color difference. Here are some simple tips for calibrating your monitor's color.

• Use Black-and-White Photos for Color Calibration

If the black-and-white image shows color shifts (such as a bluish or yellowish tint), it indicates an imbalance in the RGB channels.

• Alternate Between Near and Far Observation

Observe the screen from both close and distant perspectives to ensure the colors remain consistent regardless of distance. Viewing from too far away may result in red or blue color shifts.

• Adjust Specific Colors for Calibration

If the image appears cool or bluish, reduce the blue channel or increase the red and green.

If the image looks warm or yellowish, lower the red channel and slightly increase the blue.

To make HDR work, both your monitor and computer need to have HDR turned on. If only one of them is set to HDR, the colors on the monitor might get messed up, often looking gray.

Enable HDR on Your Monitor

1. Press the menu button on your monitor.

2. Find Color or Display settings.

3. Look for HDR and switch it On/Auto (some monitors turn HDR on automatically).

Turn On HDR on a Windows PC

1. Make sure both your monitor and graphics card support HDR.

2. Use HDMI 2.0/2.1 or DisplayPort 1.4. to connect the devices. 

3. Enable HDR in Windows Settings.

• Go to Settings > System > Display.
• If you have multiple monitors, select the one you want to adjust.
• Scroll down and turn on Use HDR.

4. Fine-Tune HDR Settings

• Click HDR Settings under the toggle to adjust brightness and color.

5. Keep Your Drivers Updated: Make sure your GPU drivers are up to date to avoid compatibility issues.

Turn On HDR on a macOS

1. Make Sure Your Mac and Monitor Support HDR.

2. Enable HDR

• Go to Apple Menu > System Settings > Displays.
• Select your monitor and turn HDR on.
• Adjust Brightness if Needed.

3. If HDR makes the screen dim, try adjusting the brightness manually. Some MacBooks automatically lower brightness with HDR on, but turning HDR off and back on might help.

The reason

Black bars or stretched images usually happen when a monitor with a different aspect ratio is connected to a device. For example, connecting a 16:10 monitor to a 16:9 laptop or console can cause these issues.

What Causes Monitor Black Bars?

Monitor Black Bars Appear with Fixed Aspect Ratios

If you connect a device with a fixed 16:9 aspect ratio (like a Nintendo Switch) to a 16:10 monitor that automatically detects aspect ratios, you’ll likely see black bars at the top and bottom (since 10 - 9 = 1). 

Extended Display and Video Playback Can Trigger Monitor Black Bars

When connecting a laptop in extended mode, if the input source is 16:9, black bars will appear, especially when playing videos with a fixed aspect ratio. 

What causes Image Stretching?

Most game consoles operate in 16:9. If you want to eliminate the black bars, you can manually adjust the aspect ratio to fill the 16:10 screen. However, this will stretch the image vertically (stretching 9 to 10), and unoptimized 16:10 monitors may force that stretch.

But if you're looking at documents, there won’t be any stretching since the computer automatically recognizes the resolution. In extended mode, the resolutions of the main and secondary displays typically don’t conflict.

What should I do?

Ignore the Black Bars

In fact, if you want to eliminate the monitor black bars, you will have to deal with image stretching which can't be solved. So it ultimately depends on your personal preference.  If you want to keep the original image quality of the game's screen ratio, the black border can't be removed. As you can see in the pictures below, it doesn't affect the gaming experience.

Damaged or loose cables, like USB-C or HDMI, can cause connection issues with the monitor, which may also prevent the touchscreen from working properly. You can try connecting the cable to other devices. If it doesn’t work properly, it might be time to get a new one.

Investigate Hardware Failures

If none of the above steps help get your touchscreen display working properly, it’s likely that the touchscreen itself is damaged. In this case, your best option is to contact customer service for a product replacement, as long as it's within two years of your purchase.

Other Touch Monitors Besides the UStation Delta Pro Touch

Some people bought touch monitors that support touch types such as 2-point, 5-point, or 10-point. That means you can use your finger to touch to get the response from a monitor. Those touch monitors are capacitive touch screens that are not compatible with touch pens, so you can't use a stylus to draw or write. If you're looking to draw or write, consider a model that includes a touch pen, like the UStation Delta Pro Touch.

UStation Delta Pro Touch

If you use the UStation Delta Pro Touch but also can't use the stylus pen to draw or write, you may be facing the following problems:

• Using the Non-original pen.
• Your stylus pen is dead.
• The stylus pen is damaged.

When you meet these problems, you can try to use the following tips to resolve them.

Check the Stylus’s Supported Protocols

If you're using a stylus pen isn't the original one for the monitor, make sure its protocol matches the original. You can find the protocol type in the product specs. GEEKPORTER's stylus pens support the MPP protocol, so a pen with a different protocol might not work well with our monitors.

Generally, there are a few main types of stylus pen protocols.

• MPP (GEEKPORTER supports)
• Wacom
• Active Capacitive
• N-Trig
• HID

Make Sure the Stylus Pen Has Enough Battery

If the stylus pen isn't working for drawing or writing on the touchscreen, it might be because the battery is running low. Simply replacing the battery should fix the issue.

Check for Any Damage on the Stylus Pen

If you're using the original stylus pen for the monitor and replacing the battery doesn't help, try using the pen on your tablet (if it's compatible). If the tablet doesn't respond either, the pen might be damaged. However, if the tablet works fine with the pen, the issue could be with the monitor's touchscreen. In this case, you should buy a new touch pen. If you recently purchased the product, please reach out to official customer support for a replacement.

The Basic Operations of Touch Screen 

Touchscreens vary in interaction based on touch points. One-point touch supports basic actions such as clicking and dragging, while two-point touch enables gestures like pinch-to-zoom and rotation, enhancing the user experience by allowing more intuitive interactions. Five-point touch recognizes multiple points for more complex gestures, and ten-point touch can detect ten points simultaneously, allowing for fast, accurate responses and a wide range of gestures.

GEEKPORTER's touchscreen monitors offer different gesture capabilities depending on the operating system, including:

• 1-point touch: macOS.
• 2-point touch: macOS.
• 5-point touch: Android (currently limited to the Unify y).
• 10-point touch: both Windows and Android.

Windows

Most of our touch monitors support 10-point touch for Windows, allowing for a variety of complex gestures. Here are the basic operation.

To Click (Single Tap)

A quick tap to select or open something, such as tapping an app icon to launch it.

To Double-Click (Double Tap)

Double-tapping an icon or file opens it or zooms in on images in certain apps. You can double-tap a photo to view it in full size.

Long Press

Pressing and holding on an item brings up extra options or menus. You can long press a file to see options like rename or delete.

Drag

Touching and holding an item allows you to move it to a new location. You might drag an app icon to rearrange it on your home screen.

To Drag and Drop

By touching and holding an item, you can drag it to your desired location and release it. For instance, you can drag a photo from your gallery into a message to share it.

Two-Finger Pinch

Pinching two fingers together zooms out, while spreading them apart zooms in.  This gesture helps you to see the details of a table or picture.

Two-Finger Scroll

Sliding two fingers up or down lets you scroll through content smoothly. This is useful for browsing a webpage or reading a document.

Three-Finger Swipe

Swiping three fingers allows you to switch between apps or open specific features quickly, enhancing your multitasking experience.

Four-Finger Swipe

A four-finger swipe is often used to return to the home screen or access the multitasking view, keeping navigation simple.

Rotate Gesture

Placing two fingers on the screen and twisting them lets you rotate an image or object, making it easy to adjust its orientation.

Five-Finger Spread

On an external PC monitor, spreading five fingers lets you access special features or menus, making it easy to return to the home screen. For other touch displays without a keyboard, this gesture is used for zooming in and out.

macOS 

Due to compatibility limitations, GEEKPORTER touchscreen monitors only support one or two-point touch functionality on macOS. 

One-point touch

macOS's one-point touch supports single tap, double tap, long press, drag, and drag-and-drop. The specific gesture actions have already been mentioned in the section discussing Windows.

Two-point touch

Two-point touch allows for more interactive controls than single-point touch, including pinch-to-zoom, rotate, and two-finger scrolling.

Android

When Android devices are connected to GEEKPORTER's touchscreen monitors, they support ten-point touch functionality. This allows for a more interactive and versatile touch experience, utilizing multiple touch points for gestures like pinch-to-zoom, rotating, and multi-finger scrolling.

Yes, you can use a power bank to power your portable monitor, but you should ensure it is capable of powering your device safely. Generally, we recommend using a portable power bank with a high power output, such as 65W. In this article, we will explain how to use a portable power bank to charge your monitor. If it fails to work, we will provide the best solution.

What Factors Should I Consider Before Using a Power Bank?

Power Output of the Power Bank

If your power bank's output doesn't match the monitor's power requirements (usually due to insufficient power output), it may fail to charge. You should ensure that the power bank supports an output that matches or exceeds the monitor's need. For instance, a monitor that requires 45W should be paired with a 45W power bank at least. Additionally, check the voltage (e.g., 5V, 9V, or 20V) to ensure compatibility.

Resolution of the Monitor

The monitor's resolution is an important fact for a power bank. Monitors with higher resolutions, such as 2K (QHD) or 4K (UHD), typically require more power than standard Full HD (1080p) monitors. If you plan to use a high-resolution monitor, ensure that your power bank has sufficient output to meet its power demands.

Protocols Supported by the Power Bank

Even with the same power output, the voltage and current are also important factors. For example, when connecting the same monitor to different devices, it may be need different voltage and current. You can use a standard 5V 2A power bank when connecting to a laptop. However, when connecting to a phone, you'll need a power bank that supports the PD protocol, which can provide 9V, 12V, or even 20V and above. 

So if you're planning to use a power bank to charge your portable display, make sure it supports the PD protocol. Some lower-powered options, like those with PD 1.0 or PD 2.0, might not provide enough juice. Check the table below to compare power outputs and protocols for different power banks. To get the best results, choose one with a wattage equal to or higher than your monitor's charger. For example, if your charger is 65W, pick a 65W or higher power bank for reliable charging.

(DP) Power Output

PD Protocol Type

5W - 10W

PD 1.0 / PD 2.0

10W - 18W

PD 2.0 / PD 3.0

18W - 30W

PD 2.0 / PD 3.0

30W - 60W

PD 3.0

60W and above

PD 3.0

Capacity of the Power Bank

The capacity of the power bank determines how long it can power your monitor. A higher capacity, such as 20,000mAh or more, allows for extended use of the monitor. For example, if a monitor consumes 65W, a 20,000mAh power bank can theoretically power it for about 1-2 hours, considering efficiency losses. 

Once you've decided on the power output you need, consider choosing a power bank with a higher capacity. This will ensure your display gets fully charged or allows for multiple charges. Based on an estimated Charging Efficiency of 80%, we've compiled a table showing the power bank usage times for monitors at different resolutions and brightness levels:

How Do I Connect a Power Bank to a Portable Monitor?

Not all monitors are designed to be powered by power banks. Verify whether your monitor is compatible with portable power sources. Ensure that the power bank has enough and the correct types of ports (e.g., USB-C, USB-A) to connect seamlessly to the monitor. Once you ensure the power bank can power your potable monitor, you can connect them  as follows:

1. Ensure the power bank is fully charged.
2. Use a USB-C or other compatible cable. 
3. Plug one end of the cable into the power bank.
4. The other end is into the monitor's powr input port.
5. Verify that the monitor is powered on (e.g., the indicator light is on or the screen starts up).

Why Should I Use a Power Bank for My Monitor?

The first advantage is you can power your monitor anywhere, like travel, outdoor use, or presentations. Second, you can keep using it when power outages. What's more, if you can't find a nearby outlet, a power bank can help you immediately. Last, it is easy to run with it for many portable monitors having low power needs.

What Are the Drawbacks of Using a Power Bank?

You can't always rely on the power bank, because it has a finite charge. Sometimes, you might buy a power bank doesn't match your monitor, so that you have to return and repurchase a new one. Besides, you may meet the drawbacks as follows:

• Limited capacity may not fully charge larger devices like laptops.
• High-capacity models take hours to recharge.
• Larger power banks are less portable.
• Capacity decreases over time.
• Improper disposal adds to e-waste.
• Low-quality models can overheat or cause fires.
• Often unsuitable for high-wattage devices.

FAQs

Is It Possible to Use Any Power Bank for a Portable Monitor?

No, not all power banks are compatible with portable monitors. You should ensure the power bank's output meets the monitor's needs.

How Long Can a Power Bank Run a Portable Monitor?

Many power banks will provide estimated usage times, such as 1 hour, 1.2 hours, 2 hours, etc. You can usually find this information when purchasing it.

What Are Other Options Besides Power Banks for Monitors?

Besides power banks, you can power monitors using AC adapters, laptop USB-C ports (if supported), portable battery packs for higher wattage, or solar chargers for outdoor use.

What Is Color Gamut?

When discussing color gamut, we refer to the range of colors that a specific display device or color space can render, which is typically defined using a color model or color space (such as sRGB, Adobe RGB, and others). The colors displayed will vary depending on the coverage of the color gamut. Many monitors may support different gamuts, which means you may see distinct colors even when displaying the same image.

Different color spaces have different coverage on the gamut horseshoe, but there is overlap. sRGB is a subset of Adobe RGB and DCI-P3, covering about 70% of Ad`obe RGB and 86% of DCI-P3, but it cannot display wider greens or more vibrant reds. Adobe RGB and DCI-P3 partially overlap, with Adobe RGB emphasizing greens and DCI-P3 excelling in reds and yellows. 

How Is Color Gamut Measured?

Mastering the correct method for measuring color gamut can prevent most measurement errors.

1. Monitor Warm-up:
2. Disable Auto-Brightness:
3. Lighting Control:
4. Calibration Steps:

Why Color Gamut is not 100%?

The percentage of color gamut is relative to a standard (e.g., sRGB, Adobe RGB), so a monitor that doesn't reach 100% may be because it covers a different standard. For example, a monitor may cover 100% sRGB but only 80% Adobe RGB.

If a monitor is designed to conform to a specific color gamut standard, its coverage within that standard will generally approach 100%. However, achieving an exact 100% can be challenging due to factors such as measurement tolerances or hardware limitations, often resulting in a color gamut coverage of approximately 97% to 99%.

If the color gamut isn't reaching 100% due to hardware limitations, it could be caused by one of the following reasons.

1. Backlight Spectrum Defects
2. Color Filter Efficiency
3. Driver IC Precision

What Other Ways Improve Color Accuracy?

Getting accurate colors on your screen is simple. Calibrate your monitor and adjust basic settings like brightness and contrast. Make sure your setup stays updated. These small steps will improve the accuracy of your display. Here's a quick guide to help you adjust everything easily.

• Calibrate your monitor with tools like colorimeters.
• Apply ICC color profiles for your device.
• Adjust monitor settings (brightness, contrast, color temperature).
• Upgrade to a monitor with wide color gamut support.
• Work in consistent, neutral lighting conditions.
• Keep GPU and monitor firmware updated.
• Check colors on multiple devices or outputs.

What Causes a Monitor to Make Noise or Beep?

If your monitor is making noise, it could be caused by one of these factors:

• The audio source might be experiencing sound loss.
• The HDMI cable could be poorly connected or damaged, leading to noise.
• There might be an insufficient power supply.
• The spot where the monitor is placed could have minor magnetic interference.
• The speaker might be damaged.

How Can You Troubleshoot Monitor Noises?

Check the Audio Source

The first thing you should notice is ensuring the issue isn’t originating from the device that’s connected to your monitor. Test with different audio sources (e.g., smartphone, laptop, gaming console, PC) to isolate the problem. Sometimes, audio loss or distortion occurs due to a faulty or incompatible source. Or, the audio itself may have noise.

Inspect the HDMI Cable

A faulty or loose HDMI cable can cause buzzing or electrical interference. You can check the HDMI cable is securely connected and free from damage. If needed, try replacing it.

Verify Power Supply

When your monitor isn't getting enough power, it might cause performance issues or noise. To resolve this, try using an external power source. After connecting it, check to ensure the outlet is working properly.

Check the Placement Environment

With the growing popularity of USB-C monitors, many users wonder: Can my monitor charge my laptop and support fast charging at the same time? The answer is yes, but it depends on a few key conditions. In this guide, we'll explain when reverse charging works, what affects charging speed, and how to check if your monitor and laptop are truly compatible.

What Is Reverse Charging?

Reverse charging means the monitor supplies power to your device (like a laptop or phone) through the USB-C cable, rather than only receiving power. This feature is especially useful when you want to simplify your desk setup and reduce the need for separate chargers.

When Reverse Charging Won't Work

Not all situations allow reverse charging. Here are some common cases where it won't activate:

• Devices that require their original power source: Some devices, such as the Nintendo Switch, need their own specific charger and cannot be powered by a monitor.
• Incompatible voltage or power requirements: If the monitor only supports 5V 3A (15W), but your laptop requires 9V, 15V, or 20V via PD protocol, the monitor cannot charge your device.
• Limited PD output: A few monitor models with PD 30W may not support reverse charging. If reverse charging is important to you, please check with our support team before purchasing.

Battery Monitors: Limited Reverse Charging Power

If your monitor includes a built-in battery, the reverse charging function is intentionally limited to 5V / 1.5A (7.5W). This is done to prevent battery overload and extend battery lifespan. While it may be enough to power smaller devices like smartphones, it's not suitable for charging laptops.

Non-Battery Monitors: How Much Power Can You Get?

For monitors without a built-in battery, the reverse charging output depends on the input power, the monitor's own power consumption, and an efficiency factor.

Theoretical Calculation:

• If you use a PD 30W power adapter and the monitor consumes 15W:

➤ Reverse charging ≈ 30W × 80% - 15W = 9W

• If you use a PD 45W adapter:

➤ Reverse charging ≈ 45W × 80% - 15W = 21W

 Note: These are theoretical values. In real use, power consumption may vary depending on screen brightness, resolution, and usage, so actual reverse charging output may be lower.

What About Fast Charging?

To enable fast charging, the monitor must support Power Delivery (PD) and the voltage levels must match your device.

For example, a monitor equipped with PD 3.0 30W may support the following profiles:

• 5V 3A
• 9V 3A
• 15V 2A
• 20V 1.5A

If your laptop also charges at 20V, and the monitor is operating at 20V 1.5A, fast charging can be activated. But if the voltage doesn't match, your laptop will charge more slowly.

Note: If you're unsure about your monitor's supported PD voltage, you can check the product specifications table on the website. Or feel free to contact us, and we're happy to help.

Conclusion

So, can a monitor charge your laptop with fast charging?

Yes, your monitor can charge your laptop, and even support fast charging, but only if these three conditions are met:

• The monitor supports USB-C Power Delivery (PD)
• The output wattage is high enough (e.g. 21W with a PD 45W adapter and 15W monitor)
• The voltage matches your laptop's charging needs (e.g. both use 20V)

Still unsure? Check your laptop's PD specs or contact us. We're here to help!

Before using the OTG port, you should know what cable connects your computer to the monitor. 

● Using USB-C to USB-C connection

When using the USB-C to USB-C connection, the monitor's OTG port allows you to connect external devices like a mouse, keyboard, or USB flash drive.

● Using HDMI Cable

If the computer is connected to the monitor via HDMI, an additional USB-A to USB-C cable is required, linking the computer's USB-A port to the monitor's USB-C port.

What Would You Like to Connect?

● Connect a USB Drive, Hard Drive

You can plug in a USB stick or external hard drive to read or save files directly on the monitor. 

● Connect a Keyboard and Mouse

You can use a keyboard or mouse with your portable monitor, which is great for easy navigation. Some touchscreens with OTG let you use a keyboard and mouse, turning your monitor into a mini computer. 

● External SD Card Reader

A portable monitor with OTG can also connect to an SD card reader, allowing you to access the data on your SD card, such as dashcam footage. 

How to Set It Up?

1. Check if your monitor has OTG support and see what type of OTG port it uses (Micro-USB OTG, USB-C OTG, or USB-A OTG).
2. Use an OTG adapter or cable (e.g., Type-C OTG to USB-A, USB-C to USB-C connection) to connect the device you want to use. 
3. Make sure the storage device (USB drive, hard drive) is formatted correctly (usually FAT32 or exFAT).
4. Once connected, the monitor will recognize the device and let you use it.

How to Check If Your Portable Monitor Has an OTG Port?

1.Check Monitor Specifications

You can look for "OTG support" or "USB OTG" mentioned in the device's official documentation or user manual.  If you haven't purchased it yet, you can just check the product specification sheet for OTG.

2.Use an OTG Adapter

Plug in an OTG adapter and connect a USB device like a  flash drive or mouse. If the device recognizes it, it supports OTG.

3.GEEKPORTER Portable Monitor with OTG Port

GEEKPORTER portable monitor with OTG Port are available in the following hot models. If you're excited about new products with OTG support, feel free to take our survey or reach out to our customer support team!

The Reason

Device Does Not Support Full Feature USB-C to USB-C

If your device doesn't support Full Feature USB-C to USB-C, you might encounter the issues mentioned above, particularly the "No Signal" problem.

Incorrect Connection Order

For the GGame, connecting the HDMI cable or USB-A to USB-C first may lead to power or display issues, as the signal connection might cause insufficient power before the display is properly powered.

Missing PD Protocol Software in PD Chip

In a small number of GGame units (less than 2%), the PD protocol software on the motherboard's PD chip may be lost, causing the 20V power supply to drop to 5V. This can result in issues like flickering, auto restarting, or no signal.

What Should I Do?

Connect in the Correct Order

To prevent power issues caused by connecting the signal source before the power cable, follow this correct connection sequence:

For USB-C to USB-C:

1. Start by charging the display.
2. Then, connect the USB-C to USB-C cable to send the signal.

For HDMI connection:

1. First, connect the power cable to charge the display (the monitor will light up).
2. Next, connect the HDMI cable.
3. Finally, use the USB-A to USB-C cable (USB-A connects to the laptop, and USB-C connects to the monitor).

Ensure Device Supports Full Feature USB-C to USB-C

Make sure your device supports Full Feature USB-C for connecting to the display. If it does, but you're still facing issues, try swapping the connections for power and signal input between the two USB-C ports on the display. It's possible the cables are plugged into the wrong ports.

Brightness Adjustment

You can lower the brightness from 600 to 450 (below 70%). This way, even if the PD protocol isn't activated, the 5V power from the power supply will be enough to run the display normally. However, keep in mind that this might prevent you from using brightness levels above 70%.

Contact Customer Service for Return

If the above steps don’t solve the issue, or if you've confirmed that the problem is due to the loss of the PD protocol software on the motherboard's PD chip, feel free to reach out to customer service to request a return.

How to Know if Your Gaming Device Is Suitable

Decide on Resolution & Refresh Rate Needs

• For 120 Hz gaming on PS5 or Xbox Series X|S, choose a UPERFECT model rated for 120 Hz or higher (UGame C2 Pro,UColor O2, etc.).
•  If you want native 4K from a PS5 or Xbox Series X, use the GEEKPORTER-Touch G16 (which handles 2K@60 Hz).

Match Display Features to Game Types

• Fast-paced competitive titles (Call of Duty, Apex Legends) benefit from higher refresh rates.
•  Visually rich, cinematic games (Ghost of Tsushima, Horizon Forbidden West) look best on an HDR (GGame) or OLED-capable portable monitor(GEEKPORTER-Touch G16).

Match Display Features to Game Types

•  If you plan to game without being near an outlet, like camping or traveling, you can pick a model with a built-in battery . Note that consoles like PS5/Xbox cannot draw power from USB-C, so you’ll still need to power the monitor separately.

In a narrower sense, what most people think of as a PC usually includes desktop computers, all-in-one PCs, and compact systems like Mini PCs or NUCs. Can all of these PCs be connected to a portable monitor? And what are the possible ways to connect each type? Before connecting a portable monitor like those from GEEKPORTER to your PC, it’s important to check if it is fully compatible. Here’s a simple guide combining what to look for and how to check it.

1. USB-C with DisplayPort Alternate Mode

What it is:

Many portable monitors use USB-C for both power and video signal. Not all PCs have USB-C ports, and even when they do, not every USB-C port supports video output. 

PC TypeUSB-C Video Output SupportUSB-C Connection to Portable MonitorNoteDesktop PCPartial support(requires specific GPU)PossibleGraphics cards with USB-C ports are relatively rareAll-in-One PCPartial support(depends on model)PossibleRequires verifying port capabilitiesMini PC / NUCMostly supportedMostlyEspecially in newer models

How to check:

• Look for a small display icon (“DP” or "⚡" symbol) next to your USB-C port.
• Check your PC’s specifications online for “DisplayPort Alternate Mode” support or "Thunderbolt 3/4" under USB-C features.
• If unavailable, move to the HDMI option.

2. HDMI Connection

What it is:

Almost all PCs come with an HDMI port, which offers a reliable way to connect portable monitors. PC HDMI ports typically support HDMI 1.4 to HDMI 2.1 for video output. However, older versions such as HDMI 1.2 and below do not support modern resolutions like 4K or refresh rates like 60Hz. While they can output video, their functionality is limited.

How to check:

• Locate the HDMI output port on your PC.
• Check if the PC's HDMI port supports a version higher than HDMI 1.4. If not, it just up to 1080p or 720p resolution.

3. VGA Port

What it is:

If the device hasn't been upgraded with an HDMI port for video output, users will need to use a converter to connect older interfaces like VGA or DVI to HDMI. That said, since around 2008, most desktop PCs and graphics cards have come equipped with HDMI ports by default. As a result, only a small number of users today actually need these types of conversion accessories to connect to a monitor.

How to check:

•  Make sure the adapter specifically supports VGA to HDMI conversion. 

4. Monitor Settings Configuration

What it is:

After connecting the monitor, your PC needs to detect and configure the new display.

How to check:

• On Windows: Right-click the desktop → Display settings → Detect displays
• On macOS: System Settings → Displays → Add Display
• Adjust resolution and display mode (Extend, Mirror, or Second Screen Only) as needed.

GEEKPORTER monitors, known for the plug-and-play convenience, sharp visuals, and wide compatibility, are becoming a good choice for many creators. But just how well do these monitors work with cameras?

Let’s break down the camera-to-monitor compatibility and explore the best ways to connect your camera to a portable monitor.

Camera and Monitor Compatibility Overview

Up until now, to connect your camera to a GEEKPORTER monitor, there are two key things to check:

• 1. Your camera needs to have an HDMI output.
• 2. It should be able to output at 60Hz.

If you’re not sure whether your camera meets these, or if it doesn’t have an HDMI port, there might still be some options you can try. 

Note: However, please also note that some cameras with HDMI ports that do not support 60Hz output may be incompatible with our monitors. Additionally, we cannot guarantee that all cameras with HDMI ports will be compatible with our monitors. Therefore, the following table and methods only serve as a possible reference.

The most important factor in camera-to-monitor compatibility is the video output signal. GEEKPORTER monitors use HDMI and USB-C input as the standard for video, but many cameras don't support video output through their USB-C ports, so your camera must be able to output video via HDMI (Mini or Micro) or have an adapter that converts to HDMI. 

Here’s a general overview of how different types of cameras may be compatible with GEEKPORTER portable monitors:

Camera TypeVideo Output PortCompatible with GEEKPORTER Monitor?NotesDSLR / MirrorlessMini HDMILikely YesUsually use Mini/Micro HDMI → HDMI cable.Most models support clean HDMI without overlays.Industrial CamerasHDMI / SDI / AVPossiblyHDMI generally works directly.SDI/AV may require an SDI→HDMI or AV→HDMI converter.Action CamerasMicro HDMI (via Media Mod accessory)PossiblyUSB-C typically supports only data/power, not video output.You may need to install the Media Mod to enable Micro HDMI output.

Note: The above table is a theoretical reference based on whether your camera supports HDMI video output and has not been tested in practice.

Things to Keep in Mind

• Clean HDMI Output: Ensure your camera supports clean HDMI output (i.e., no overlays like battery icons or focus boxes).
• Power Supply: Some cameras and monitors may need their own power source. GEEKPORTER monitors can be powered via USB-C PD if they don't have a built-in battery.
• Resolution and Refresh Rate: GEEKPORTER monitors currently support HDMI input with up to 1080p resolution at 60Hz. Make sure your camera’s HDMI output matches the supported resolution of your monitor.
