Most new AOC monitors are designed to be connected to machines via USB. AOC monitors are reliable for the most part (since users rarely complain about issues with them).

In this article, however, we intend to examine a problem involving AOC monitors.

“Why Is My AOC Monitor Not Working?”

When you connect your AOC monitor to your machine via USB, or when you turn on your device after you’ve already connected the AOC monitor and used it in this setup, you expect your monitor’s screen to light up and start displaying some content.

How to Fix the “AOC USB Monitor Not Working” Issue on Windows 10

Fix 1: Perform preliminary checks

Before you resort to advanced fixes to resolve the problem preventing your monitor from displaying content, we strongly advise you to perform some preliminary checks.

This way, you avoid wasting your time trying to resolve problems that may not even be in play.

Do this:

1. Check the power supply to your monitor. Press your monitor’s power button to put it on (if this step applies). When your monitor is plugged in or connected to power, you are supposed to see a standby light. If you don’t see it, then something is probably wrong with the power supply to your monitor. You might have to replace the device’s power cable.

2. Examine your monitor’s connection to your computer. Check and confirm that the cable is properly inserted and the contact is strong. If your monitor is receiving power but is getting no signal (even though it is connected to your computer), then something might be wrong with its video cable.

3. Try wiggling or shaking the video cable to see if anything changes. If you have another video cable, you will do well to use it now. If your monitor supports VGA, DVI, or HDMI—which is unlikely if your AOC monitor is the simple USB model—we recommend you try another connection method. For example, if you are currently using HDMI to connect your monitor to your PC and are experiencing problems, you may want to try VGA to see if things get better.

4. Try another port on your computer. Perhaps the port you are trying to use is bad, incompatible, or faulty. If your computer is equipped with several ports—especially USB 2.0 and USB 3.0 ports—you will do well to try every one of them (using the video cable) to see if the display issues get resolved.

5. Try another display or monitor. If you have another display device that supports the same connection mode as your AOC monitor, then you may want to use it to test things now. You can even try your TV. If you get the expected content on the second display or monitor, you can take this event as confirmation that something is wrong with your AOC monitor.

Other Things You Can Try to Resolve the “AOC USB Monitor Not Working” Issue in Windows 10

Fix 5: Use a USB hub

Here, we are assuming your computer failed to recognize the USB monitor device after you plugged the latter into your PC’s port. In this case, you may utilize a USB hub—connect the USB monitor to the USB hub first and then connect the hub to your computer.

Your computer should have an easier time recognizing the USB hub and working with it. For this reason, the AOC USB monitor may start functioning as it is supposed to.

Fix 6: Use a short (or shorter) cable

Some users report that their AOC monitors come on and work only for a few seconds before going off again; others complain that their monitors get no input from their computers. If you fall into either group, then you may be able to fix your display problems by using a short cable.

It seems power interruptions become less of an issue with shorter cables, especially for AOC USB monitors, which are designed to get all their power from USB ports.

We also cannot rule out the possibility that the fault lies with the USB ports since they might be failing to deliver enough power in the first place.

Ideally, you should try as many cable and port combinations as you can and settle with the one that resolves the issue for you.
