Why does my PC monitor say no signal?

This is a very common problem that can have a few different causes. In this article we’ll go over some of the most common reasons for this error message and how to fix them.

The first thing to check is all of your connections. Make sure that the monitor is properly plugged into the power outlet and that the video cable is securely connected to both the monitor and the computer. If everything looks tight and secure, try unplugging and replugging in both the power and video cables. Sometimes the connections can become loose and need to be reseated.

If reseating the cables doesn’t work, the next thing to check is your computer’s video output settings. If you have more than one video output port on your computer, make sure that the correct one is selected. Many computers will automatically switch to the correct port when a monitor is plugged in, but sometimes this doesn’t happen. You can usually switch video ports by going into your computer’s BIOS settings or by using a hotkey combination on your keyboard.

If you’ve checked all of your connections and video output settings and you’re still getting the no signal error, the next thing to try is a different video cable. Sometimes the cable itself can be the problem. If you have another cable of the same type, try swapping it out and see if that fixes the problem. If you don’t have another cable, you can try borrowing one from a friend or taking your computer to a local electronics store to test with a different cable.

If you’ve tried all of the above and you’re still getting the no signal error, the problem is most likely with your monitor. Try plugging your computer into a different monitor to see if that fixes the problem. If you don’t have another monitor to try, you can try taking your monitor to a local electronics store to test it on a different computer.

If you’ve tried all of the above and you’re still getting the no signal error, the problem is most likely with your video card. Try removing your video card and cleaning the contacts with a soft cloth. If that doesn’t work, you may need to replace your video card.

If you’ve tried all of the above and you’re still getting the no signal error, the problem is most likely with your computer’s motherboard. You can try removing and reseating your computer’s RAM modules and your video card. If that doesn’t work, you may need to replace your motherboard.
