Hello,



Thanks for posting on Microsoft Community. We regret the inconvenience caused and will assist you in resolving the issue.



From the above description, I understand you are unable to adjust the brightness settings on your PC running Windows 10 OS.



Before assisting further, I would like to ask you few questions:

• Are you facing the above issue on a laptop or desktop?
• Did you check if the changes can be made from the Graphics properties window?

If you are using a desktop, check if the brightness of the PC can be adjusted manually using the buttons located at the sides/bottom of the monitor. If you are using a laptop, check if you are able to adjust the brightness of the PC manually by using
the appropriate brightness adjusting function key on the keyboard layout.



If the issue persists, I suggest you to follow the steps below to check if the brightness of the PC can be adjusted using the
Graphics properties window.

• Right click on the desktop and select Graphics properties from the context menu.
• Choose Advanced mode and click on OK.
• From the left side panel, select Color Enhancement and check if the
  Brightness adjusting bar is displayed on the right side panel of the window.
