AOC Monitor Display Not Working

Is your AOC display not working or malfunctioning? Monitors not working are generally a sign of a defective video card or an improper graphics driver. However, sometimes, monitors fail for other reasons.

If your AOC monitor is not displaying an image, here are a couple of things you can do to troubleshoot your PC build to see why your image isn’t displaying.

AOC monitor not working

Is Your AOC Monitor Properly Powered

This may seem like an easy fix, but it’s often overlooked – check your power cable, power strip, and even the outlet that it’s plugged into just to rule out that those aren’t the issues.

Most modern monitors use some sort of energy-saving technology, so if there’s no signal, they may appear to be off – but there should be an indicator light somewhere on the model.

Check to see if it’s powered.

  • If there’s a standby light when the monitor is plugged in, can you toggle the power to see if it tries to change power states?
  • Do you see an error of any kind when it turns on?
  • Do you have any other devices you can plug in?
  • Does the monitor work when they are plugged in instead?

If the power is working to everything else, but the AOC display problems, it could be the power cable for your AOC monitor. See if replacing the AOC Power Cable fixes the issue. You can call or contact AOC to get a replacement power cable.

Do Your HDMI / DVI Cables Work?

If your monitor seems to be receiving power, but no signal is provided when plugged in, you could have a frayed video cable.

If you wiggle the cable, does anything happen? Have you used the cable with another device and had it work? Is there a visible error being displayed on the AOC monitor?

Do you have another cable to try in its place? If your AOC monitor supports VGA, DVI, or HDMI, try a different type of cable to see if your cable or port is damaged.

You can easily buy these cables at most electronics manufacturers.

If replacing a cable fixes the issue, discard the old cable and use the new one.

Try Using Another Display

Do you have another monitor, TV, or other display that supports the same plugs your computer or laptop has? Try plugging those in to your computer instead of the AOC monitor.

Do you get a response from the TV when you’re on the correct channel? If so, your monitor may be broken or faulty.

You should reach out to your retailer if your monitor is still under warranty, or reach out to AOC to try to receive a replacement.

Graphics Card Problem

If your graphic card has multiple output ports on it, try a different port for your cable to see if the issue is the port. Sometimes, whether you’re on AMD or Nvidia, one of your outputs will fail. If this clears the problem, contact your retailer or manufacturer to try to get a refurbished card.

Sometimes, a faulty or out-of-date driver can cause graphics issues as well. If you’re on a desktop and you have an integrated graphics output, try plugging into that output and updating your video card’s drivers.

If you’re on a laptop, try using your native screen and updating your graphics drivers as well as your chipset drivers.

    Can you please confirm if there exists a Driver ( USB ) for Windows XP for AOC Monitors

    Do you know what model it is? It’ll help identify which driver you may need.

    Why does this article not say wether an aoc monitor could connect to integrated graphics

  4. Matt G July 16, 2020 at 8:19 am

    Shouldn’t matter – so long as your integrated graphics card is working. It may output a low resolution or give an error depending on how old the Integrated Graphics card is.

    If I haven’t started my computer in hours, on the first startup the display will say something along the lines of “HDMI cable input not detected”. I then force restart my computer, then it works on the second boot. This happens every time since getting my monitor. I can’t find any articles referring to this type of issue.

    I have a message that states”disc not formatted”. How do I get the message to go away?

    I have a AOC monitor model e2343Fk. I am using a docking station with a laptop and two monitors. The other monitor is a Dell. I unplugged everything without shutting down anything. When I plugged everything back in, everything worked but my AOC monitor. The adapter shows a solid green light until I plug it into the monitor. Once plugged into the monitor the green light starts to blink and I have no power to this monitor at all. It is strange that it worked before I unplugged it. Does anyone have any suggestions?

    Thanks in advance

    running this program. its been on 95% for 2 1/2 hours ???

    Same here . The DP port is not working CADYCE docker and I forced to use HDMI which is not providing optimal quality.

    I just called AOC directly and the support tech told me that AOC monitors are “not built to fully work with docking stations.” The reason I called was I’m unable to get a 4k monitor rated at 60hz to go above 30hz. That is one of the most frustrating reasons I’ve ever heard of.

    Try the little button , Center, bottom front, it turns the monitor on and off. The button also moves like the old mouse scroll wheel and provides different options. One option it appears is to sleep the monitor and not allow a signal input, roll that button forward and the monitor awakens and works fine.

    i cant connect dvi to my aoc C24G1 someone pls help

    Did you get it finished? Driver Support’s customer support can be found at

  14. Matt G January 20, 2021 at 8:08 am

    The CADYCE dock could be the issue. DP and DVI can provide the extra quality for larger/higher refresh rate monitors, the conversion may be losing signal.

    My issue is my monitor isn’t even appearing to be receiving power. The thing is it was working just fine when I last used it, but today, those dumb touch keys aren’t working. I can’t even turn my monitor on. The computer is working fine. I’m not getting a “No Signal” or anything. I’m getting nothing. Don’t know if the AC cable stopped working, or if it’s the monitor itself. I have no such “green button” on mine; I have that damn set of touch keys. Never had an issue with any other monitor on any of my computer EVER. It can’t be the graphics card or any of that, because just the other day, EVERYTHING WAS WORKING JUST FINE. Never had any problems with any other I had. I guess you can just never have all touch display to replace good old fashioned hardware. Especially when the screen won’t work and there is no alternative button to power the display on. Not getting another touch key monitor if its gonna just crap out again.

    AOC model 16T2 bought brand new. Charged it for 6 hours, swap cable, swap charger, di everything : DEVICE NEVER WORKS SCREEN STAYS BLACK.
    Orange LED light keeps on blinking as long as the charge cable is plugged. When pressed, the green LED light stays ON for a few seconds then goes OFF.
    I am very disappointed. Although I bought 2 pieces of the same model, the other one is working perfectly.
    Please help.
