I can't setting the brightness on my Windows 10

, i've tried to update all driver but still doesn't work.

Then i wanna tried to check the register, gonna check 'FEATURE TEST CONTROL'

-

  • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class{4d36e968-e325-11ce-bfc1-08002be10318}\0001

I can't find the 'FEATURE TEST CONTROL', i just found 'FEATURE SCORE', is it same?

There is also only feature score in 0000

    There is a new version of the graphics driver on the Nvidia website released on Sep 12, 2023. Downloading and installing this version of the driver should fix the problem. You can use the "Automatic Driver Updates" from this link to download and install the latest version of the driver.

    I tried uninstalling this driver before, it fixed the problem of always at maxed brightness, but it did not fix the issue of no being able to change brightness

    Hi, perry,

    Sorry to hear you're experiencing this issue.

    The brightness feature is related to the graphics driver. Please provide some more details to help identify what is causing this problem. Are you using a laptop or a desktop? Which is the full model of your computer/laptop or motherboard?

    Also, attach a screenshot of the System Information Page:

    1-Right-click on Start then click on Run

    2-Type: msinfo32 and click on Ok

    And a screenshot of the version of the driver installed:

    1-Right-click on Start then click on Device Manager

    2-Click to expand the Display adapters

    3-Right-click on the graphics driver and click on properties

    4-Take a screenshot of the General and Driver tab
