    Screen Brightness Doesn't Change When the Slider is Adjusted.


    My computer Inspirion 5490 AIO will not change brightness when I try to use the brightness slider. I have had this computer for a year, and right after I updated from Windows 10 to Windows 11 a few weeks ago, it has been stuck on the max brightness and I cannot fix it. Whenever I try to update my drivers, it says that I already have the best drivers. Any advice would be helpful!

    :)

    Missing Adjust Screen Brightness slider in Power Options

    My HP laptop performed a Windows Update today. As a result, I've lost my "Adjust Screen Brightness" slider in Power Options. I can still find it in Settings - Display.

    I have Win 10. I've found a YouTube video (specifically for Win 7) that suggests going to Device Manager - Monitors - Properties - Uninstall Device, but I've also read that doing so will merely result in the same driver being reinstalled.

    What should I do to get the "Adjust Screen Brightness" slider back in Power Options?

    Thanks so much for your help.

    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.

    Missing Adjust Screen Brightness slider in Power Options

    Yes, to clarify, I've lost my "Adjust Screen Brightness" slider in Power Options. I can still find it in Settings - Display. In addition, I can adjust brightness with the Function keys.

    Thanks. I guess I will have to use Settings or the Function keys to adjust brightness from now on.
