If you cannot adjust brightness in Windows 11, try checking if “Change brightness automatically when lighting changes” is enabled. If not, try disabling and enabling the graphics driver, reinstalling drivers, or updating Windows, as brightness issues can sometimes stem from driver or software problems.
Here’s a more detailed breakdown of potential solutions:
Check for Automatic Brightness:
Go to Settings > System > Display.
Look for the “Change brightness automatically when lighting changes” toggle and ensure it’s turned off.
Graphics Driver Issues:
Disable and Enable:
In Device Manager (search for it in the Start menu), go to Display adapters, select your graphics card, and disable it, then re-enable it.
Reinstall Drivers:
Uninstall the display drivers through Device Manager (right-click, Uninstall device, and select the option to delete the driver software). Then, reinstall them, ideally by downloading the latest drivers from your computer manufacturer’s website.
Update Drivers:
Check for driver updates in Device Manager (right-click, Update driver) or through your manufacturer’s software.
