I know there is a shortcut key to rotate screen in Windows by 180, 90 and 270 Degrees but somehow I am not able to get this working now.
I am on MAC these days but I just check on my Windows Laptop and it is Ctrl + Alt + <ArrowKeys> but remember this only works on Intel Motherboards and you should have graphic rotation turned On
Ah, a classic. That's what I could have used some months ago when I was desperate about how to rotate the screen to how it was before.
