How to fix no signal on computer monitor

If your computer monitor is displaying the dreaded “no signal” error, it means that it’s not receiving any input from your computer. There are a few things you can do to try and fix this problem.

First, make sure that all the cables are properly plugged in. If you’re using a DVI or HDMI cable, try unplugging and replugging it into the port on your graphics card. If you’re using an analog cable (VGA), try unplugging and replugging it into both the port on your graphics card and the port on your monitor.

If that doesn’t work, try restarting your computer. If your monitor still says “no signal,” there’s a good chance that your graphics card is the problem. Try removing your graphics card and plugging your monitor directly into your motherboard’s onboard video. If your monitor works with onboard video, then your graphics card is most likely defective and needs to be replaced.

If you’re still having no luck, there’s a possibility that your monitor is the problem. Try plugging your monitor into a different computer. If the monitor works with the other computer, then it’s most likely the problem is with your original computer and not the monitor.

If you’ve tried all of these things and you’re still getting the “no signal” error, then you may need to replace your monitor.
