Well I went in to my Physics class today to see if my MBP would work with her projector. I hooked the two up together and it worked- my MBP screen was on the projector. I unplugged, shut down, and took my MBP home. I just turned it on and now the screen is jacked up. There are 2 thick black bars on both sides of my screen, and everything is oversized and fuzzy. Help please.
