    Can't change screen brightness when playing full screen games


    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?

    :)

    screen brightness on windows 10

    Hi,

    Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

    To manually adjust the screen brightness, we suggest following these troubleshooting steps:

    • Click Start, then select Settings.
    • Choose System, then select Display.
    • Under Brightness and color, move the Change brightness slider to adjust the brightness.

    Feel free to post back if you have other concern.

    Change screen brightness

    My laptop screen is dull. Need to make it brighter. However the suggestion --> Start - Settings - System - Brightness and color

    does not work. It is already set to max. brightness but there is no reaction. Screen remains dull. By the way there is no change if I move slide to minimum brightness, it would not change brightness level at all. Any suggestion?

    Can't change screen brightness when playing full screen games

    Unable to Change Screen Brightness of Laptop


    So I'm not sure how long this has been happening but for some reason, I can't change the brightness on my laptop screen. I have linked a picture and as you can see, my brightness says 0% and that I can't change it, however my actual brightness is at 100%. I have looked around everywhere and the only responses I have found don't work for me. Here's a list of everything I have tried:
    - Reinstalling Display Drivers
    - Rolling Back Display Drivers
    - Reset Settings on UWT4
    - Power and Battery Settings
    (UWT4 or Ultimate Windows Tweaker 4 is a customizer for Windows 10 and I thought that might be the problem but it wasn't)

    If anyone has any suggestions on how to fix this, it's greatly appreciated! Thanks! -
