Update the Graphics Driver to the Latest Build

  1. Firstly, manually update the system’s Windows (as many OEMs prefer to use the Windows Update channel to release the drivers’ update) and make sure no update is pending left to install. Then check if the dimming issue is resolved.
  2. If not, then update the system’s drivers. Make sure to check the OEM website for the updated drivers as well. Also, if your OEM has an update utility (like Dell Support Assistant or Nvidia GeForce Experience), then use that utility to update the drivers.
  3. Once the drivers are updated, check if the issue is resolved.

Reinstall the Graphics Driver

  1. Firstly, make sure you have downloaded the latest version of the Graphics driver from the OEM website.
  2. Then right-click on the graphics device in the Device Manager (as discussed above) and choose Uninstall Driver.
    Uninstall the Graphics Adapter
  3. Now, in the window shown, checkmark the Delete the Driver Software for This Device and click on the Uninstall button.
    Delete the Driver Software for This Device for the Graphics Driver
  4. Then follow the prompts to uninstall the graphics driver and afterward, reboot your PC.
  5. Upon reboot, if Windows installs the default graphics driver, let it complete and then check if the screen dimming issue is resolved.
  6. If not, install the latest graphics driver (downloaded at step 1) and check if the screen dimming issue in full-screen games is resolved.

If the issue persists, then you may play the games in Windowed mode till the issue is resolved. If that is not an option, then you may try the system restore feature or reset your PC to the factory defaults.
