Using the Monitor Self-Test
Monitors provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run Monitor Self-test.
- Turn off both the computer and the monitor.
- Unplug all video cables from the back of the monitor.
- Turn on the monitor. The floating dialog box would appear on-screen if the monitor cannot sense a video signal but is working properly.
- This box will also appear during normal system operation if the video cable is disconnected or damaged.
If the monitor continues to be blank after verifying that the self-test works, then the issue might be with the video cable /video adaptor or the computer itself.
