Powershell script to change screen Orientation

Question 1

I wrote a script to change primary screen orientation to portrait. my screen is 1920X1200
It runs and no error reported. But the screen does not rotated as i expected.

The code was modified from Set-ScreenResolution (Andy Schneider).
Does anybody can help me take a look?

Some reference site:

Set-ScreenResolution :
