A no signal error on a monitor can leave you scratching your head without answers. Thankfully, this kind of problem is usually easy to troubleshoot. To help you deal with display issues, here are some troubleshooting tips you can try when your PC monitor has no signal. Before you rush to rip out your graphics card or head to Amazon to buy a new monitor, you should look carefully at your PC and monitor to ensure you have no cabling or power issues.

This is a simple check to complete. Start by tracing the cabling between your monitor and PC to ensure that you have no loose connections. You may also find that the display cable itself is at fault. If you see cable damage, or if the cabling is quite old, swap it out for an alternative.

This can sometimes immediately resolve any issue with your monitor display. There could also be a power issue that prevents your monitor from working correctly. A no signal error on a monitor could be a sign that your PC monitor is ignoring the graphics output from your PC.

This can sometimes happen if the input source on your monitor is set to the wrong device. This allows you to connect multiple devices to the same display. If this is the case, make sure that the input source on your monitor is correctly set.

A PC monitor has a set range of display resolutions that it can use to display your PC output. Thankfully, fixing a blank monitor screen after changing your display settings is an easy process. If the monitor has suddenly lost resolution after changing the settings yourself, wait 15 seconds—Windows will revert back to your previous resolution after this point.

There are ways to get around this, including restarting Windows and booting into Safe Mode to bypass the issue with a higher resolution. By default, Windows will use a much lower display resolution in Safe Mode than during normal use.

This will allow you to change your standard display resolution to a lower setting that your monitor can support. Alternatively, use the second window to change your resolution for a bit of a trial-and-error. If the resolution stops your monitor from working, Windows will revert the setting to the previous setting that worked. When a display problem occurs, the monitor itself can often be the focus of your diagnostic efforts, but the graphics card your PC uses is often the bigger culprit.

Thankfully, this is often resolved by updating the graphics card drivers so long as the graphics card is relatively new. This includes support for new monitors and display resolutions.

Replace the monitor attached to your PC with a spare if you have one available. Likewise, if your main monitor stops working, but a spare works fine, then this could indicate a problem with your monitor hardware. However, this does not necessarily rule out a further software issue. For instance, a broken graphics card could stop any display output to your monitor, resulting in a no-input signal.

You should look at your repair options under warranty or, failing that, consider buying a new monitor. This might be the case if your display takes a long time to switch on, for instance.
