What Causes No Signal on Monitor?

Before we diagnose the issue, we should understand what can cause this issue. The signal can be lost due to several reasons. It can be due to a loose or a faulty cable, poor configuration settings, outdated drivers, hardware issues, or a defective monitor. You can narrow down the issue with linear and logical troubleshooting.

Check Cables & Connectors

If you are using a laptop, there is nothing major you can check except the hinge connectors of the laptop. You can also check for a broken or bleeding screen in the case of a laptop.

Desktop users need to check the cable that is connected through the desktop to the CPU tower. Check for a loose broken cable or the cable connectors if there is any broken pin identified. Turn off the power, unplug the HDMI / VGA cables, and plug it back into the port.

Reseat the power cable as well to check the power supply. If you have a spare cable or another computer, try replacing the cable to check if the problem is with the cable or connector. If there are multiple input sources, check that the cable is connected to the right input source.

Reset or Replace the Monitor

Every Original Equipment Manufacturer (OEM) has a different setting to reset the monitor. Some have a reset button at the front/back of the monitor panel. You can press and hold the reset button for a few seconds until the light blinks to reset the monitor back to factory settings.

If you have an additional monitor or another computer, you can try replacing the monitor along with the cables to check if the problem is with the monitor, cables, or the CPU itself. Swapping your monitor can clear major doubts if the problem is with the monitor or the cable.

Update Graphics Drivers
