Okay. A couple weeks ago, my dad installed an ACER Display Management program for his 23.3" monitor. Now, whenever I try to play a game in native resolution (1440x900) the game is off center. (19" ACER) I need to get this fixed because Call of Duty is so off center, you see maybe 70% of the screen, and the rest is pushed to the bottom left. Any help is appreciated.
