The easiest way to fix a flickering screen on Windows 11 is to update or reinstall your Display Driver, as corrupted graphics software is the most common cause. To do this, press Windows key + X, select Device Manager, expand the Display adapters section, right-click your graphics card (e.g., Intel, AMD, or NVIDIA), and select Uninstall device. Once you restart your computer, Windows will automatically attempt to reinstall the correct driver, which typically stops the flashing. If the issue continues, check your Refresh Rate by going to Settings System Display Advanced display and ensuring the rate is set to the recommended frequency (usually 60 Hz or matching your monitor's spec), as a mismatched rate can also trigger constant screen blinking.
