步驟
你的系統
- 1
See if one app causes it
Open Task Manager (Ctrl+Shift+Esc). If Task Manager flickers too, it's likely the display driver; if it doesn't, an app is likely the cause.
- 2
Restart the graphics driver
Press Windows+Ctrl+Shift+B. The screen goes black briefly while the driver restarts.
- 3
Update the graphics driver
Get the latest driver from your GPU or laptop maker.
- 4
Check the cable and refresh rate
Reseat or replace the cable, and set a refresh rate the monitor supports.
- 5
Try turning off variable refresh
G-SYNC, FreeSync or Windows' variable refresh can flicker at low frame rates on some panels.
還是不行嗎？
- Flicker that shows up in photos of the screen but isn't visible can be normal backlight dimming.
