As with all things tech, a simple restart may get everything back to normal. You’ll need to try a force restart, though, as we can assume you can’t see the screen and do this from the options.

Press and hold the power button until the computer shuts down. This should take about 10-15 seconds. When the computer is off, press the power button again to turn it back on.

There is a chance your screen options are not configured correctly. This is especially common if you’re using multiple monitors, or a laptop connected to an external monitor.

There are ways to show only one of multiple monitors, and the button combination to switch between display modes isn’t too hard to press accidentally. If you think this is the problem, try to cycle through the display modes. You can do this by pressing Windows + P. Repeat this button combination to see if your dead monitor lights up.

If your computer turns on but still shows no display on the monitor, it’s time to start digging deeper into the issue. Let’s ensure no cable is loose.

First things first, is the monitor even on? This may seem like a silly question, but sometimes we freak out when the monitor isn’t even on. Press the power button, just in case.

You may also want to plug another device into the monitor. This accomplishes two things. First, if the monitor doesn’t work with any other device, then you’ve identified the culprit. The monitors likely stopped working. We have a list of the best budget monitors, if you want to replace it.

If the monitor works when you connect other devices to it, you know the issue is with your PC. Keep going through the tips below.

Does your computer have multiple display out ports? Sometimes the motherboard is weird about picking which port to send a display signal to. It doesn’t hurt to try other display ports.

For example, if you use a discrete GPU, ideally, you want to connect your monitor directly to the graphics card. Try the other HDMI, DisplayPort, DVI, or VGA ports on both the GPU and motherboard.

For some reason, computers can often fail when you connect too many things to them. Try to remove everything that’s not necessary. This may include external hard drives, USB drives, disc readers, printers, etc. You should probably also unplug the mouse and keyboard.

Try turning the computer on and see if the monitor works. If it does, you can plug in whatever you want and continue using your computer as usual.

Your motherboard BIOS is what controls your computer components, and how they interact with each other. It also ensures your computer boots up appropriately. BIOS software can sometimes fail, so it may be a good idea to reset it if you’ve tried everything and you’re still having issues with your computer displaying an image.

If you want to proceed, follow our guide on how to clear and reset the BIOS memory on a PC. Just keep in mind that this will clear the time, and disconfigure any changes you may have made to the BIOS.

If you’ve tried it all, but still can’t get the display to work, maybe it’s time to get professional help. You should look into your warranty or insurance, to see if the manufacturer or insurance provider can help. Otherwise, you might have to find a technician.
