ASUS Portable Monitor Not Detected [11 Proven Fixes]

1- Tighten Loose Cables Connection

If your ASUS portable monitor is not detected, it could be because of a loose cable connection. 

To ensure proper detection, you must ensure that the cables connecting your ASUS monitor to the computer or other device are securely connected. 

All power and video cables, such as HDMI, DisplayPort, and DVI, should be firmly plugged into your ASUS monitor and the source equipment. 

If, even after ensuring all cables are connected securely, your ASUS monitor is still not being detected, you may need to update its drivers or adjust settings on the computer or device to which it is connected. 

It is also possible that there may be other issues going on, like a faulty cable or an outdated graphics driver on the computer, which might cause your ASUS monitor not to work properly.

2- Check HDMI Cable

When the ASUS portable monitor is undetected, the first step must be to check the HDMI cable that connects it to an external device such as a laptop or gaming console. 

The HDMI should be securely connected and properly inserted into the ASUS monitor and auxiliary device. 

Suppose you have confirmed that all your cabling is secure and in good condition. 

In that case, you should check if power is on the ASUS portable monitor by trying additional methods like pushing any button or turning it on with a remote. 

To troubleshoot further, consider replacing your current HDMI cable with a brand new one just in case there is something wrong with it. 

If, even after this step, your ASUS portable monitor is still not working, there may be a hardware or software issue inside it.

3- Try Switching HDMI Port

If ASUS portable monitor is not detected when connected via HDMI, the user should first check to ensure the cable is securely connected and undamaged. 

Switching to a different HDMI port could provide a solution if everything appears in working order. 

Sometimes different ports on the same device may be configured slightly differently, leading to the ASUS monitor not being detected. 

If a different HDMI port is unavailable, a different device, such as a laptop, could also be an option. 

Finally, if none of these options resolves the issue, the problem may be with the ASUS monitor display input.

4- Use the Correct Display Input

You may need to check the display input settings if your ASUS portable monitor is undetected. 

Depending on the ASUS monitor model, multiple ports and technologies, such as HDMI, USB Type-C, or DisplayPort, can be available. 

Your ASUS display might not be connected correctly for optimal performance. 

Ensure all external cables are connected securely, and check the ASUS user manual for details on how to set up your ASUS display correctly. 

If the ASUS monitor is still undetected, you may need to try a different cable or port on your device. 

You can also try restarting the ASUS monitor and the laptop/PC it is connected to. 

If these steps do not work, you should try physically removing and reinstalling your RAM.

5- Physically Remove and Reinstall Your RAM

Physically Removing and Reinstalling your ASUS portable monitor RAM is a simple but important step when troubleshooting display issues. 

First, ensure your ASUS monitor is powered off and unplugged. Then, locate the two screws holding the RAM on the back of the ASUS monitor. 

Remove these screws, and the RAM should slide out easily. Once you have removed the RAM, check for any signs of damage or debris clogging up the ports. 

If no problems are found, lightly wipe down the RAM and ports with a soft cloth to remove any potential dust buildup. 

Reinstall the RAM into the ASUS monitor and secure it with the two screws. Finally, plug in your ASUS monitor, turn it on, and check to see if your device is now detecting it. 

If your ASUS monitor is still not being detected, then you may need to look to update your device’s drivers.

6- Use the HDMI Port on Your Dedicated Graphics Card

You can effectively use the HDMI port on your dedicated graphics card to prevent your ASUS portable monitors from being detected. 

Plugging the monitor into a dedicated graphics card instead of the motherboard ensures that your computer will correctly recognize and detect your ASUS monitor. 

Since it has more ports and better output quality than most onboard graphics cards in motherboards. 

To plug in successfully your ASUS monitor to the dedicated graphics card, you need to open up all display settings in the operating system and make sure that it is recognized as a second monitor at first. 

If nothing works out for you, try reinstalling or updating the drivers on your computer to properly detect the ASUS portable monitor.

7- Use the Right Projection Option

If your ASUS portable monitor is not detected, it may be because of a projection issue. 

You will need to make sure you use the right projection option for your ASUS monitor to ensure proper detection, which may involve selecting the correct ports. 

Such as HDMI or VGA, or selecting the correct display type, such as mirrored or extended display. 

After verifying that your ASUS monitor is properly connected to your computer, you will likely have to restart it so that the display driver can detect the ASUS portable monitor. 

If these steps do not resolve the issue, try uninstalling and reinstalling ASUS device drivers or updating them to ensure compatibility with your system.

8- Force Detect the Display

Force Detect the Display is a process that can detect ASUS portable monitors when regular methods are not detecting them. 

This can be done using the device’s settings menu or an external display management software application. 

The user must first access the device’s settings menu and navigate to the display settings to find their ASUS monitor in the list of available displays before selecting it. 

Then choosing ‘force detect.’ After this is perceived, the ASUS portable monitor should be detected and ready for use.

9- Check Your Display Adapter

If your ASUS portable monitor is undetected, the important step is to check your display adapter. 

To do this:

  1. Open the Device Manager on your computer and locate the Display Adapters section.
  2. Look for any devices listed that are ASUS-branded and click on them to check their status.
  3. If they appear disabled or not working properly, right-click and select ‘Enable Device.’

If this doesn’t help, you may need to update the drivers for your ASUS monitor.

10- Try Changing the Refresh Rate

The ASUS portable monitor may not be detected because of your display’s refresh rate settings. 

The refresh rate determines how often the image on your screen is refreshed, and a higher refresh rate will provide you with a smoother viewing experience. 

If your ASUS monitor fails to get detected properly, try adjusting the refresh rate to match the one supported by your ASUS device. 

If you are unsure which refresh, check if your ASUS monitor is connected properly to your system and all cables are inserted firmly into their respective ports. 

You should also ensure that the power settings on the ASUS display are set to ON and receiving power supply. 

Lastly, make sure to check if there are no problems with connecting any external devices like speakers or microphones parallel to it.

11- Update Your Display Driver

If your computer fails to detect the ASUS portable monitor, you should likely update your display driver. 

Since display drivers are often hardware-specific, it is essential to ensure that the correct ASUS portable monitor driver for your device has been installed properly on your computer. 

To do this, you must go to ASUS’s website and download the driver for your device. 

Once you have downloaded the correct driver, install it onto your computer and restart. 

This should normally sort out any issue with detecting the ASUS portable monitor on the computer. 

It is also important to check if all other USB devices connected to your computer are working appropriately, as they might interfere with detecting your ASUS portable monitor.
