    How to Change Brightness of Built-in Display in Windows 10


    If you have a laptop or tablet with a built-in display, you might need to occasionally change the screen brightness level. For example, if you want to use your laptop outdoors on a sunny day, you might need a brighter screen to see the display clearly. Or, if you're in a dark room, you might want to make the screen less bright.

    A brighter display uses more power, which reduces battery life.

    If the Screen brightness option isn't available, your PC might not support brightness adjustment or you might need to update your display drivers.

    Starting with Windows 10 build 17639, Microsoft removed the display brightness slider in Control Panel Power Options and the “Display brightness” section under Power Options Advanced Settings.

    Starting with Windows 10 build 18282, Microsoft heard your feedback about a specific case where a display can become brighter when transitioning from a battery charger to battery power. Microsoft is modifying the display brightness behavior so that this can no longer happen. If a person adjusts their display brightness, that brightness will now be remembered as their preferred brightness whether they are on battery or connected to a charger. This new behavior results in a more consistent and battery friendly experience. This does not affect battery saver mode settings; if a person has opted into lowering the screen brightness in battery saver mode, their display will still dim when the battery is below the threshold selected.

    This tutorial will show you different ways to change the screen brightness of a built-in display on your Windows 10 laptop or tablet.


    Brightness settings will not be available for an external monitor connected to the computer. You will need to use the physical brightness button on the monitor, or change from the on screen menu for the monitor.

    Brightness settings will only be available for a built-in display like on a tablet or laptop. If supported, you can adjust screen brightness of an external monitor connected to a desktop computer in the NVIDIA Control Panel.

    If you do not see any of these brightness settings or they are not working, be sure you have the correct and latest graphics driver installed.

    If you do already have the latest graphics driver installed, then uninstall and reinstall the driver to repair it.

    Hello Ruu, :)

    Is this a PC, laptop, or tablet?

    If PC, then the screen brightness setting won't be available.

    It's a setting only available on tablets and notebooks.

    You should still be able to manually adjust the brightness level with the monitor's on screen settings though. Check your monitor's manual for more on how to do so. It'll usually be a button at the bottom of the monitor to press.

    reg_valuename  = "DCSettingIndex"
    reg_type    = "REG_DWORD"
    reg_value    = 65
    ;
    ; power plan HIGH PERFORMANCE - set video dim to 100% for AC
    ;
    reg_keyname   = "HKLM\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes\8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c\7516b95f-f776-4464-8c53-06167f40cc99\aded5e82-b909-4619-9949-f5d71dac0bcb"

    Instead of running a command that flashes a slow-loading Powershell window, you can put this in a batchfile:
    Code:
    FOR /F "tokens=4" %%v IN ('powercfg GetActiveScheme') DO (SET a=%%v)
    powercfg SetDcValueIndex %a% SUB_VIDEO VIDEONORMALLEVEL <Brightness Level>
    Substitute <Brightness Level> in the above batch code with 0 to 100 brightness level percentage you want.
    To make the command window invisible, you can put this in a .vbs file:
    Code:
    Dim wshShell
    Set wshShell = CreateObject("WScript.Shell")
    wshShell.Run """C:\tools\Adjust Screen Brightness.bat""", 0
    Set wshShell = Nothing
    Substitute C:\tools\Adjust Screen Brightness.bat in the VBScript above with the filepath of your batchfile.

    Batchfile:
    Code:
    @ECHO OFF
    SETLOCAL EnableDelayedExpansion
    FOR /F "tokens=4" %%v IN ('powercfg GetActiveScheme') DO (SET a=%%v)
    SET "b=      GUID Alias: VIDEONORMALLEVEL"
    SET LF=^
    
    
    REM The two empty lines are required here
    SET "output="
    FOR /F "delims=" %%v IN ('powercfg q %a% SUB_VIDEO') DO (
       IF DEFINED output SET "output=!output!!LF!"
       SET "output=%%v"
       SET "output=!output:*DC Power Setting Index: =!
       IF !c! == 1 (IF NOT !output! == %%v GOTO endloop)
       IF !output! == !b! SET /a c=1
    )
    :endloop
    SET /a r=!output!
    ECHO The current screen brightness level is: %r%%%
    PAUSE
    EDIT: Please note, it should work on English versions of Windows 10/11. I only tested it on the Dutch version of Windows 11 Home, it works. On the German version of Windows you would need to modify the batch code so it matches the language translations for the powercfg command's output (whereas on the Dutch version of Windows it uses the English language instead ). Anyway, here is a slightly shorter version:
    Code:
    @ECHO OFF
    SETLOCAL EnableDelayedExpansion
    FOR /F "tokens=4" %%v IN ('powercfg GetActiveScheme') DO (SET a=%%v)
    SET LF=^
    
    
    REM The two empty lines are required here
    SET "output="
    FOR /F "delims=" %%v IN ('powercfg q %a% SUB_VIDEO VIDEONORMALLEVEL') DO (
       IF DEFINED output SET "output=!output!!LF!"
       SET "output=%%v"
       SET "output=!output:*DC Power Setting Index: =!
       IF NOT !output! == %%v GOTO endloop
    )
    :endloop
    SET /a r=!output!
    ECHO The current screen brightness level is: %r%%%
    PAUSE
    EDIT2: This is even shorter still, and it should work on any language of Windows:
    Code:
    @ECHO OFF
    SETLOCAL EnableDelayedExpansion
    FOR /F "tokens=4" %%v IN ('powercfg GetActiveScheme') DO (SET a=%%v)
    SET LF=^
    
    
    REM The two empty lines are required here
    SET "output="
    FOR /F "delims=" %%v IN ('powercfg q %a% SUB_VIDEO VIDEONORMALLEVEL') DO (
       IF DEFINED output SET "output=!output!!LF!"
       SET "output=%%v"
       SET "output=!output:*: =!
    )
    SET /a r=!output!
    ECHO The current screen brightness level is: %r%%%
    PAUSE
