How to fix a hair thin black line across screen

MEG_106

Hello! I just noticed that there is a hair thin, horizontal line across my screen. It disappears when the background is light (I.E white) but it reappears whenever the background is colored. Does anybody know how to fix this?

To address the faint horizontal line on your screen that disappears on light backgrounds, try the following steps:

1. Check Connections: Ensure all cables are securely connected. If possible, test with another monitor to determine if the issue is with the screen or the computer.
2. Update Drivers: Update your display drivers and check for any firmware updates for your monitor.
3. Adjust Settings: Experiment with different resolutions and refresh rates in your display settings.
4. Monitor Sleep Settings: If the issue resembles burn-in, adjust your display sleep settings to prevent prolonged static images.

If the problem persists, it may indicate a hardware issue requiring professional evaluation.
