@Ahmad-f79 Does it work on Windows 11 too? I'm trying it but it shows the volume indicator instead

The below code works fine in Windows 11. You can adjust the brightness using Shift+Mouse Scroller Up/Down.

;Shift + Mouse Scroller

+WheelDown::
    AdjustScreenBrightness(-5)
Return

+WheelUp::
    AdjustScreenBrightness(5)
Return

AdjustScreenBrightness(step) {
    service := "winmgmts:{impersonationLevel=impersonate}!\\.\root\WMI"
    monitors := ComObjGet(service).ExecQuery("SELECT * FROM WmiMonitorBrightness WHERE Active=TRUE")
    monMethods := ComObjGet(service).ExecQuery("SELECT * FROM wmiMonitorBrightNessMethods WHERE Active=TRUE")
    minBrightness := 5 ; level below this is identical to this

    for i in monitors {
        curt := i.CurrentBrightness
        break
    }
    if (curt < minBrightness) ; parenthesis is necessary here
        curt := minBrightness
    toSet := curt + step
    if (toSet > 100)
        return
    if (toSet < minBrightness)
        toSet := minBrightness

    for i in monMethods {
        i.WmiSetBrightness(1, toSet)
        break
    }
}

@erbanku Thank you, yes I'm using that piece of code, but it does not let the brightness bar popup appear

I tried using the code posted by @Ahmad-f79 but it doesn't work (I'm on Windows 11)

@Rabelaiss Did you find a solution to display the Brightness OSD on W11 ?
