Ich habe ein Skript geschrieben, um die primäre Bildschirmausrichtung in Hochformat zu ändern. Mein Bildschirm ist 1920X1200 Es läuft und es wurde kein Fehler gemeldet. Aber der Bildschirm dreht sich nicht wie erwartet.

Der Code wurde von Set-ScreenResolution (Andy Schneider) geändert.
Kann mir jemand helfen, einen Blick darauf zu werfen?
