So one time i was playing portal when all of the sudden my macbook pro died. when i turned it back on the screen, in a ways, shrank. What ever is displayed on the screen does not take up the whole thing. there are about 1-2 inch black bars on both sides. I've tried restarting the computer, even updating it, but nothing is working. it's not just when i watch a movie or play a game, it's when ever it's on. even when the computer is turning on and i see the white screen with the apple logo it still has the black bars. Please, if you know how to fix this, please tell me how. Thank you.
