Using X-Arcade Joystick, I Inverted My Screen Permanently

[SalParadise]

While playing a game using my X-Arcade joystick, I somehow inverted/flipped my screen.  The screen is flipped both inside the games and outside of the games (just in Windows).

Anybody have any idea of what I did, or more importantly, how to get it back to normal?

Note: I was just using the default button configuration on X-Arcade's joystick.

Thanks.

I don't know what hotkey you pressed so I can only give the mouse directions to undo it. 

Tilt your head just enough that you can follow the upside down mouse controls.  Then right click on the windows desktop and go to screen resolution.  Orientation is an option there and you probably just want landscape instead of landscape (flipped).  Then disable hot keys in your graphics options so it doesn't happen again.

That worked perfectly.

Many thanks.

If it's an Intel board, CTRL + ALT + the arrow keys are the hot keys for directions. You can fix the orientation like that, then disable hot keys like monkeybomb recommended.
