What Am I Using?
Screen flickering?
Find whether the flicker affects one app, your desktop or the monitor’s own menu. Compare the cable, display mode and app settings.
Does it flicker outside the affected app?
Switch to the desktop or another app. On an external screen, try opening the monitor’s own menu.
Device and operating system
Compare a second app with similar content
A single-app symptom points towards how that app renders or plays its content.
- Save your work and update the app through its official updater.
- If the app has its own graphics acceleration setting, record the original value before changing it. Restart the app and restore the original setting if there is no improvement.
Check the cable and display mode
Flicker across apps can involve a cable, display mode or device driver.
- For an external screen, reconnect the cable and try a direct connection if possible.
- In display settings, try a manufacturer-supported refresh rate. If the monitor’s own menu also flickers, tell its manufacturer.
Record the mode and trigger
A repeatable change makes a flicker report more actionable.
- Note which screen flickers, whether it follows wake or charging, and which app was visible.
- If possible, film it with a second device. Review the frame for private content before sharing.
