Hello, Try below methods to fix screen flicker on windows 11: Screen flickering in Windows 11 is usually caused by a display driver issue or incompatible app. To determine whether a display driver or app is causing the problem, check to see if Task Manager flickers. Then, based on that information, you'll need to update, rollback, or uninstall your display driver or update or uninstall the app. 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 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. 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 Windows Update recently made updates to your device, roll back your display driver. Otherwise, try updating or uninstalling your display driver to fix the flickering or scrambling problem. Troubleshoot screen flickering in Windows - Microsoft Support
