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.
