Your screen flickers or flashes at random times
Screen flicker is almost always caused by a display driver problem, a loose monitor cable, or the wrong refresh rate setting. A 30-second test with Task Manager tells you which one it is.
Your monitor is constantly receiving signals from your graphics card. When that signal has a problem — a driver glitch, a loose cable, or a mismatch in refresh rate — the screen flickers. The fastest way to figure out what's wrong is to watch whether Task Manager flickers along with everything else. If it does, it's a driver or hardware problem.
Fix-IT-Bot will walk you through each step — just tap, no typing needed.
Skip — I just want a technicianCommon mistakes to avoid
- Updating the display driver without first testing Task Manager — if Task Manager flickers too, a driver update is correct; if it stays still, updating won't help
- Ignoring flickering that's getting worse — this is a sign the hardware is degrading
- Assuming the monitor is broken when it's actually a cable that costs 10 dollars to replace
Signs you need professional help
- Driver update didn't fix the flicker and refresh rate is already correct
- The screen goes black during a flicker and takes several seconds to come back
- It's a laptop and flicker continues after updating the driver
