    3. Select the Driver tab and then select Roll Back Driver.
    4. Click Yes to roll back your display driver and restart your computer.
    If the Roll Back Driver option is unavailable, Windows does not have a previous driver to roll back to. In this scenario, you can try updating or uninstalling your display driver in the Driver tab.
  2. If Task Manager does not flicker, an incompatible app is probably causing the problem. In this scenario, update or uninstall an incompatible app:
    1. Check if any app needs to be updated from the Microsoft Store or the manufacturer’s site. If yes, update the app.
    2. If step a does not work, uninstall the app:
      1. Select the Start menu on the taskbar and then select Settings.
      2. Select Apps ➙ Installed apps.
      3. Scroll down the list, find the app you want to uninstall, and then select Uninstall.
      4. In the popup window, select Uninstall.
      5. If you're asked to confirm your choice, select Yes.
        Check in the recently used app if screen flickering usually occurs in a specific app. If yes, prioritize uninstalling that app.
