  4. Check Delete the driver software for this device box and click OK.
  5. Your monitor driver is uninstalled, so now you need to click Scan for hardware changes icon.
  6. This will install the default monitor driver and your brightness settings should work now.

After installing the default monitor driver, check if the problem is still there. This issue can also occur if your monitor driver is disabled. To check if that’s the case, do the following:
