Re: PS3 or TV...Console World or Home Theater??
Turn on TV and set input to port being used. Make sure PS3 is connected via correct cable, then turn on PS3 via power button and hold for 5 seconds (release after the second beep). It should automatically configure your PS3 to the TV's native resolution for all settings.
