Screen Flickering or Flashing
The display flickers, especially during scrolling or video playback.
Before you start: save any open work and note down what you were doing when the problem started — that context helps if you need to search further or ask for help.
- Update your graphics driver first — this fixes the majority of flickering cases, especially after a recent Windows Update.
- Check if a specific app causes it: if flickering only happens in one program, it's likely that app's rendering settings, not Windows.
- Disable Windows Desktop Manager temporarily to test if the issue is display-related: right-click desktop > Display settings > Advanced display > check refresh rate matches your monitor's supported rate.
- Unplug and reseat the video cable — a loose connection causes exactly this kind of intermittent flicker.
- If flickering is isolated to one app like Chrome, try toggling hardware acceleration off in that app's settings.

Frequently Asked Questions
Is flickering dangerous to my monitor or graphics card?
Occasional flickering isn't damaging by itself. It's more a sign of a driver, cable, or refresh-rate mismatch than a hardware safety issue, though a genuinely failing cable or connection is worth replacing regardless.
Could this be caused by the monitor itself rather than Windows?
Yes — testing the same monitor on a different device (or a different monitor on this PC) is a quick way to tell whether the monitor or the PC's graphics output is actually responsible.
