Question Monitor randomly started acting up?

Apr 1, 2023

I own a Dell S2421HGF and use a dual monitor setup. Like an hour ago I noticed that my Dell monitor started flickering white lines on the display and it kept going away and reappearing.

I have checked and it's not a Software issue since I only had the Power cable plugged in and it was still just white lines flickering. I have no idea what caused this issue. It sometimes dissapears for a few minutes but then it goes back to bugging out. Is there a fix or do i have to get a new monitor?


Welcome to the forums, newcomer!


your panel has other inputs, try them and see if the issue persists. If the issue is persistent on another donor system, then yes the panel needs replacing. If you want to get the panel repaired, you might very well need a mainboard for the panel.
