    Sadly, the Powershell method does not work on Windows 10 OS build 19043.1237, v21H1.

    I get the following error:

    Get-WmiObject : Not supported
    At line:1 char:2
    + (Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods …
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo : InvalidOperation: (:) [Get-WmiObject], ManagementException
    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

    You cannot call a method on a null-valued expression.

    This would be very useful for me if I can get it working.

    Another way to adjust the brightness is to type Brightness in the Taskbar’s Search Field which opens up the Display Window to Brightness and Color to adjust.

    None of them, as they all work only on the main display. I tried all 7.

      Go to your desktop, right click, (another way to right-click is to press ctrl f10), press display settings, and then it should show you some sort of brightness bar.

    You adjust the screen brightness via the monitor buttons on the physical monitor

    Using the Function key with Delete and Backspace is the easiest, it can be done without looking at the keyboard – unlike trying to find the brightness keys in the long row of function keys. Sadly this Function key method is not available on the Surface Pro X.

    I have windows 10 with an exterior monitor. I could not find a brightness setting to change to save my life. So my retinas burned for 30 minutes while I tried all the suggested routes, none worked. I have the Intel HD graphics driver which is supposedly the most up to date one. If I go to control panel> Intel HD Graphics Control Panel > Color Settings (really?)> there is a brightness setting there which is maybe just the brightness of colors so it sort of helped?
