Its very difficult to type this, my entire display is now tilted 90 degrees. The right side of my screen is now the bottom of my like, OS/web browser/windows... any idea how to fix this? I think I might have accidentally hit something on my keyboard...

Please disregard the question. The answer is that a really stupid windows feature is ctr+alt+direction key, with the direction being the side you want to be 'up'

Press CTRL/ALT/right arrow one after the other (not simultaneously) and it will switch the direction of your screen.

If that doesn't work - Right-click on a blank area of your desktop and select "Properties". Click on the Settings tab, then the Advanced button. I can't tell you where to go exactly from there because I'm not sure of your operating system or video card, but go through each of the tabs until you find the rotation setting you are looking for.
