I have a DELL 30" display which is not supported by my older G5 video card. I got a ATI Radeon 9600 pro Mac (AGP) for my older G5. I put it in and installed all software, and it did not work, my resolution could not go past 1280 x 800. So I then updated the driver from the ATI website (june 2005!) like it says to to in the instructions. After that now my display preferences only have one setting to offer - 1280 x 800, and it does not recognize the display in the top of the menu, it just says "Display" when before it said "DELL3007WFPHC". And there is no "detect Display" button. Great... so i called ATI support and they have me exchange my card for a new one. nope same issues. so i called ATI support again, he said "oh you should of not updated the driver, you need to uninstall the driver, but sorry i don't know how to do that on a mac...please call apple" Long story short how do I uninstall a driver for a display/graphics card??? FYI-all displays (19", 22") I try to use this this mac have the same issue now.
