1.Test your monitor on another PC

Most newer monitors have a self-diagnostic function that will show a message if the monitor is  not receiving a signal from the computer. If you are seeing this message, then your monitor is probably fine. If the screen is black, try the monitor on another PC to troubleshoot the issue to make sure it’s not your PC.


2. Listen for a Beep Sound

If the computer is make a beeping sound when turned on, a card, cable, memory module, or processor inside the computer might have come loose.

Do you hear the computer’s fans? If you don’t hear anything your PC might not be on, also check the power lights on the computer, if they are not on the problem is related to the computer, not the monitor.

3. Check the Monitor’s Cable

That might be the simplest, most obvious problem but people don’t always check this. Sometimes when moving your monitor when cleaning or for any other reason, could cause the cable from coming loose. Also check the cable for bent pins or damage to the external insulation as you will only have to replace the cable, the monitor might be fine.

4. Reset and update the BIOS

You can do this without having to be able to see on the screen.


  • When you restart/turn on your computer start pressing F10 repeatedly for 8 Secs.
  • The press the Down Arrow 3 times.
  • Then, press Enter 2 times.
  • The computer will then restart. If the monitor is still blank, it could be a graphics card issue.

    Thanks for your input – Win+P should bring up options to split the screens. Give that a shot.

    Driver Support can help diagnose software issues with devices and Windows working together. If you’re not using a Windows computer with this HP monitor, we may not be able to assist. However, I would try using the monitor with another device to see if you can get a signal with it. If you can, it may be the camera device you’re using. You may want to try contacting the manufacturer of the device you’re plugging it in to to see if they can help you.

    I changed my monitors settings to the lowest possible ones and then now it won’t turn on. I’m stuck on a no signal page and can’t load into windows to change my hertz and stuff back. I also tried running my PC on another screen but it worked fine. How do I fix this?
