I was hoping someone might have a clue as to how I can get my old M7613 15" Graphite Studio Display to function with my old 450 MHz Power Mac G4 AGP with DVI out. The 15" Graphite Studio Display has a DVI, USB, and Power Combo Cable http://www.everymac.com/monitors/apple/studio_cinema/specs/apple_studio_display_gray.html I hooked the G4 up to a VGA display in combo with the Studio Display but the G4 only recognizes the VGA Display. I have an amber power light on the Studio Display but nothing else. System Preferences Displays only recognizes the VGA display as connected. When hooking up the Studio Display alone we do not even get the amber power light, and obviously nothing is displayed. We are trying to set this G4 up just for web browsing and would like to use the Studio Display. I assume that the Studio Display is using just a standard DVI and the G4 DVI is compatible. Any ideas sincerely appreciated. Thanks.
