Screen flickering/flashing in Windows 10 is usually caused by outdated PC display drivers, incompatible app or loose or damaged wires. To determine whether a display driver, app or wire is causing the problem, check to see if the screen is damaged and check to see if Task Manager flickers. Then, based on that information, you'll need to update, or uninstall your display driver or update or uninstall the app. In this guide, we are going to find out all the different ways you can fix this problem.
If the computer screen is broken or has cracks, it may flicker or flash. The best way to figure this out is to connect your computer to an external monitor. If everything looks clear on the external monitor, then it is an issue with your laptop's screen, and not the motherboard or other hardware. If you are encountering the same issues externally, then you may need to take it to a repair shop to get your computer back on track.
We will use the Task Manager app to establish what might be causing the flickering screen. Press Ctrl + Alt + Delete (or Ctrl + Shift + Esc) to open Task Manager.
Check to see if your have the correct refresh rate for your computer screen. If you’re finding that your screen flicker only occurs when you’ve linked your PC to an external monitor, the problem may be the refresh rates. A laggy refresh rate can look like flicker, try changing the refresh rate to fix this problem.
Step 1: Select the Start button, then select Settings > System > Display > Advanced display settings.
Step 2: Under Refresh rate, select the rate you want. If the screen flickering stops, this may have been the solution you needed. But, if it doesn't stop, something else is causing the problem.
