rightclick your desktop. Click resolution I think. And check to make sure your computer ins't thinking its not connected to a second monitor.
Wow fixed. I love you so much.
It wasn't the resolution, I know I messed with stuff loads of settings, and I'm smart enough to know nothing was wrong with it buttt
I didn't know there was a setting for multiple monitors, and by default, it was selected to two monitors extend.
I changed it to one, :D
Love you
Locked.
