I dont know what to do here...It was fine before i installed MS Office. Now whenever i restart, regardless of what i have set the ATV resolution to (i tried 720p and 1080i) it always boots up OSX in 720x480, and the colors look a bit off, also. Any ideas on why this is? I may just wipe the drive and reinstall OSX if i am unable to fix it. Thanks in advance for your help!
