Why does my monitor say no signal? 5 Fixes

Monitors are an essential part of any PC or laptop. It is, after all, how you interact with a computer (or most people anyway). This also means that if your monitor starts acting up, you’re probably are in a bit of a pickle.

In this article, we’re taking a look at the “No Signal” error that monitors throw at times, figuring out its causes and giving you a few solutions to try out.

What causes the monitor no signal error?

The error is almost always caused by either a faulty cable or an issue with the monitor itself. However, other things like the following can also trigger the issue.

  • Issues with your GPU not being attached properly.
  • Port issues.
  • Internal damage on the video card (GPU).

How to fix the monitor no signal?

Here are a few simple solutions you can try out to see if they solve the problem for you.

Restart your PC

Restarting your PC might seem like a far fetched idea in this case, but rebooting can fix a bunch of seemingly random errors that pop up out of nowhere. You should also try turning your monitor off, leaving it like that for some time and then turning it back on again. 


Check the cables

Next up, you should check the cable running between your GPU and monitor. Since the monitor is turning on and showing the error, the problem is in the cable itself. Make sure all connections are firmly in place and that the cable doesn’t have any physical damage. If you have an extra one lying around, be sure to swap cables as well.

Try another monitor

Yes, not all of you will have access to an external monitor to try this step out, but if you do, we suggest using the same cable and port on your GPU with another monitor. This should help you figure out whether the issue is in the monitor or your cable, or GPU.


Check the video card

If nothing has worked so far, try opening your PC and checking if your video card is firmly in place. Make sure you don’t have any physical damage on your card as well as a busted card won’t be able to send display signals to anything.

Replace or Repair the GPU

If the video card is, in fact, in the right place, chances are you have an issue with the GPU, and it needs replacing or repairing. If you’re using a fairly recent GPU, you should be able to get it repaired. Otherwise, it’s not a bad idea to consider an upgrade.
