Screen flickering in Windows 10 is usually caused by an incompatible app or a display driver. To determine whether an app or display driver is causing the problem, check to see if Task Manager flickers. Then, based on that information, you'll need to update or uninstall the app or update, rollback, or uninstall your display driver.
Check to see if Task Manager flickers
Press Ctrl + Alt + Delete to open Task Manager. If you don’t see Task Manager after pressing Ctrl + Alt + Delete, press Ctrl + Shift + Esc to open Task Manager.
- If Task Manager doesn't flicker while the rest of the screen is flickering, an incompatible app is probably causing the problem. In this scenario, see the Update or uninstall an incompatible app section.
- If Task Manager flickers along with everything else on the screen, a display driver is probably causing the problem. In this scenario, see the Fix your display driver section.
