If brightness option isn’t available on your Windows 10 PC, the issue might be your monitor driver. Sometimes there is an issue with your driver, and that can lead to this and other problems.

However, you can fix the problem simply by uninstalling your monitor driver. To do that, just follow these steps:

  1. Press Windows Key + X to open Win + X menu. Choose Device Manager from the list.
  2. Go to Monitors section and expand it.
  3. Find your monitor driver, right-click it and choose Uninstall.
  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:

  1. Open Device Manager.
  2. Go to Monitors section and expand it.
  3. If your monitor is disabled, right-click it and choose Enable from the menu.

After enabling your monitor, the issue should be resolved and you’ll be able to adjust your brightness once again.
