I brought a new 15" Apple LCD Studio display that has an ADC connector (and no power input + 2 USB ports- all fed by the ADC connection) I am using at home an older G4/350 (AGP graphics). This looks to have an older DVI connector. Since I cannot connect the two directly I assume I need an a DVI to ADC connector. Myu questions is, wil this work? Will the display get its power via the cable or what/ and what about the two USB ports? I belive the cable is meant to go the other way - older LCD w/ newer machine - will it go the other way?
