Can't change screen brightness when playing full screen games

Anonymous

My laptop has intel and nvidia graphics. After a recent windows 10 update, whenever I play my games on nvidia graphics on full screen, the screen brightness will dim/brighten to ~50. Changing the brightness in the windows settings (i.e. 0 or 100) does not change the screen brightness when running the game in full screen.

I have tried updating the graphic drivers, re-installing the graphic drivers, re-installing the graphics drivers to an older version, and uninstalling some windows updates (unable to uninstall KB4574727, KB4576751, KB4559309 though). None of these help to resolve this issue. Can anybody please provide a fix to this?

    Thank you for updating me about this issue.

    I apologize that those steps did not resolve the issue.

    Maybe someone else in the community has an idea.

    I tried uninstalling the drivers using the program you suggested, then re-installing the latest drivers, but it still doesn't work.

    Hi and thanks for reaching out. My name is Jan an independent Microsoft Advisor and a user like you. I'll be happy to help you out today.

    Most likely this is due to the graphics driver issue. Try clearing the Graphics drivers both Intel and Nvidia using DDU.

    Display Driver Uninstaller

    Run the application from Safe mode.

    Select Clean and restart

    Once the drivers are uninstalled

    Install the latest Graphics Card driver
