How to troubleshoot no display on a computer monitor

With several reasons on why a desktop computer monitor is not displaying an image, I suggest you not go to a local repair shop directly. Let us try some basic troubleshooting steps to help you know the cause behind your display issue.

Troubleshooting No Display on Computer Monitor

If Monitor Displays ‘No Signal’ or ‘Self Test’

If you get an error message on your monitor display like ‘No Signal‘ or ‘Self Test‘, this means that the computer monitor display is working properly, but is not getting any signal from the computer.

You can easily fix this issue by checking both ends of the video cable that goes between your computer and your monitor are pushed inside properly. In case, you have a VGA or HDMI cable, make sure that you do not screw the adapter too tightly.

Note: When you try to unplug your VGA/HDMI cable, make sure that you do not pull it directly without removing the screws completely.

Monitor Power Light is Off

At the moment of switching ON your monitor, if the monitor is not displaying a power light (small switch with light) you might have a problem with your monitor.

The very first step is to check the power adapter of the monitor. Check weather it is plugged in completely or not.

Secondly, test the power outlet with another device such as a lamp or electric screwdriver or a mobile charger to see if the power outlet works. In case, the power outlet is working properly, try to test the monitor with another monitors power cable (if it matches).

Finally, try to plug-in another monitor to your computer, just to check if the issue is not with the ‘computer‘ instead of the monitor. None of the above worked? Then your monitor is not working, take it to a local repair shop to check your monitor’s display.

My monitor has power but I have no display

If the above problem is fixed, and your monitor have power but do not have display, this may be issue of ‘video card‘ or ‘display driver issue‘.

Before going into the conclusion, first, check your video cable if it is plugged in properly into the display port on the back of your computer or not. In case there are two separate areas on your computer that have the same display adapter. First, try plugin the video card (one side) and display power plug (another side), and vice versa.

What should you do if I still have no display on my computer monitor?

Eventually, if any of the above solutions do not resolve your issue, we now recommend you to take your computer/monitor to a local computer repair shop. They will troubleshoot and check for exclusive support (hardware such as wires, etc).

In case, if your computer’s display works properly on another monitor, then please check if the resolution isn’t set too high for your monitor. If the resolution is normal, and still the problem persists, then it is time to get your monitor repaired or replaced.

If the problem continues, then there can be an issue of other components like motherboard, memory cards, or power supply, which may be causing ‘Monitor no signal‘ or lagging the monitor to display.
