Your monitor has been working well up until now. Suddenly, the monitor is saying “No Signal,” or maybe you just got the monitor, and it gives you this message instead of displaying your home screen. Either way, this can be quite disheartening.

There are many reasons why you are receiving this message. Some have more dire circumstances where you may have to replace the whole thing, but there are many steps you can take to fix it before just replacing the monitor. 

10 Fixes For Why Your HP Monitor Says No Signal

Fixing your monitor when it says “no signal” does not have to be hard. There are many solutions before you decide to return it or buy a new one. Here are ten fixes for your HP monitor you can try:

  • Restart your computer.
  • Reset the monitor.
  • Unplug and inspect the monitor cable.
  • Replace the monitor cable.
  • Change the input source.
  • Inspect adapters.
  • Remove and replace the video card.
  • Get a new video card.
  • Test with another PC or computer.
  • Check resolution configuration.

Once you have tried all of these, then it may be time to look for a replacement. It would mean your monitor’s hardware is broken, and unless you are tech-savvy, then it needs to be replaced. But until then, here is how you can do each of these to see what the cause is.

Restart Your Computer

Sometimes, simply restarting your computer can be helpful. Your computer may need an update, and restarting it was the last step. Once the computer is updated and restarted, the software can work correctly with the monitor.

Reset The Monitor

Try resetting your monitor. You can do this manually by either unplugging the power source or using the buttons at the bottom of the screen. Resetting the monitor can take it to factory settings and may fix the “no signal” problem that is occurring.

Unplug And Inspect The Monitor Cable

If you have tried the first two options and still nothing is working, unplug the monitor cable. Inspect it for any wearing and tearing. If there is a cut on the cable, then it may need to be replaced.

You can also try the monitor cable on another monitor to see if it is the cable itself. If a monitor works with that cable, then it isn’t the cable that is the problem; it is something else.

Replace The Monitor Cable

If the cable doesn’t work on other monitors or there seems to be damage on it, then you will need to replace it. This piece of equipment is fairly easy to replace, and you may even be able to use a cable from another monitor on it.

Change The Input Source

Always check your input source before you replace any equipment or the monitor itself. Sometimes the input may have been set on something else, and so the monitor is trying to display from an input that isn’t even there. This can even happen with new monitors.

Inspect Adapters

Inspect all the adapters. The adapters could have been damaged when shipped or when trying to plug things into it. If it looks like things are damaged, you will have to replace the adapters. Some adapters also may not be able to support multiple monitors.

Remove And Replace Video Card

Each PC has a video card which is why things are displayed on your monitor. It will be underneath your PC case. You can remove the card from its slot and blow off any dust. Once you have done this, you can firmly insert it back in.

Turn on your computer to see if this resolves the issue. If it does not, then you may need to replace the video card.

Get A New Video Card

If you have tried all the methods, you can replace the video card. It is a simple piece that can be replaced, and you can find it online. You can go through your manufacturer, or you can go on other seller websites.

Test With Another PC Or Monitor

Remember that this step should be performed before purchasing anything new. Your monitor may be working fine, and it is the PC or vice versa. Test your PC or Monitor with another device to see which piece of equipment is at fault.

Check Resolution Configuration

You will want to check your resolution configuration. Sometimes when your computer is set at a higher resolution than the monitor, it can result in the “no signal” message. This happens quite often when you try to use a newer gaming system on older televisions.

You can try starting in safe mode, which will cause your PC to start in a low resolution that can later be adjusted. If you have another monitor you can use, you can attach it and adjust the settings within your PC:

  • Open Window Settings.
  • Go to “system” and then “display.”
  • Find “display resolution” and open it up.
  • Change the resolution.
  • Your computer will ask you if you want to confirm these changes.
  • Select that you will keep the changes.

Now you can test to see if the other monitor will work with your PC. If you still receive the “no signal” message, then it is not the configuration of the resolution.


These simple fixes should help you figure out the issue. If it does not, then you may need to return the monitor, or you need to consult with a technician that can fix the problem. It is best to contact the manufacturer, but technicians are available to help you as well.
