If your AOC monitor is displaying the “no signal” message, it means that it is not receiving any input from your computer. There are a few things you can do to try to fix this problem.
1. Check the cables that connect your monitor to your computer. Make sure that the cables are firmly connected at both ends. If you are using a VGA cable, make sure that it is plugged into the correct port on your computer. If you are using an HDMI cable, make sure that it is plugged into the correct port on your computer. If you are using a DVI cable, make sure that it is plugged into the correct port on your computer.
2. If you are using a VGA cable, try plugging it into a different port on your computer. If you are using an HDMI cable, try plugging it into a different port on your computer. If you are using a DVI cable, try plugging it into a different port on your computer.
3. If you have another monitor that you can use, try connecting it to your computer and see if you can get a signal. If you can, then the problem is most likely with your AOC monitor and you will need to contact AOC customer support for further assistance.
