Rotate screen Powershell

Question

Does someone know a powershell code how to rotate a screen. I already use the $width and the $height parameters but is there also a rotation parameter?

I already searched on the following sites:

I already using this code:

Function Set-ScreenResolution { 
param ( 
[Parameter(Mandatory=$true, 
  Position = 0)] 
[int] 
$Width, 
[Parameter(Mandatory=$true, 
  Position = 1)] 
[int] 
$Height
) 
$pinvokeCode = @"

It looks like this is possible with the Win32 API (C/C++ libraries). With some inline C# compilation, you can P/Invoke into the Win32 API from Powershell just as you can from other .NET languages.

I've linked above to a Github script I found that changes the screen orientation from Powershell using the aforementioned Win32 API. If you want to know more about P/Invoke itself, here is the official Microsoft Documentation on the subject. For posterity, here is the script as it currently exists:

Function Set-ScreenResolutionAndOrientation { 

<# 
    .Synopsis 
        Sets the Screen Resolution of the primary monitor 
    .Description 
        Uses Pinvoke and ChangeDisplaySettings Win32API to make the change 
    .Example 
        Set-ScreenResolutionAndOrientation
