I'm hoping someone here can help me figure this out. We just bought a 30 in Cinema Display to accompany the G5 (2.0 Dual) we have at the office. The guy at the Apple Store suggested we get the Radeon 9800 Pro video card (256MB) to run the monitor, which we did. The only problem is that I can't get it to show a resolution higher than 1200 x 800 (approx., I don't remember the exact numbers). When I hook it up to my 17 in Powerbook which has the Radeon 9700 running at 128 MB the resolution is right where it is supposed to be. Does anyone have any suggestions as to why the monitor won't display at the correct resolution on the G5? Were we misinformed about the compatibility of the video card?
