I have an early 2008 mac pro with the 8800 GT video card and a Sony Trinitron Multiscan 200 GS monitor. Ever since the computer arrived I have had a really annoying problem. When I shut it down or put it to sleep for an extended period the resolution switches to 800x600. I have to click the "Detect Displays" button several times a day to get it to display its native resolution. I took it in to a local Apple shop (not an Apple retail store) and they said they could not find a problem and charged me $45 since Apple Care does not cover problems that they can't find. I was hoping someone else had a new Mac Pro w/ an 8800 GT hooked up to a CRT and could confirm that they aren't having any problems. I don't have a second monitor to compare to and am curious if it could be my monitor rather than my video card. Does anyone have any advice or a related experience for me before I take it back to the shop and risk being charged again?
