I have a 20" Apple Cinema Display (the aluminium one) and a G4 Quicksilver. My G4 does not have a DVI port. What do I need to buy so I can use my new Cinema Display. Do I need an adapter? Or do I need to buy a new video card? I would like to be able to use the screen at the highest resolution possible (2560x1600). If I get an adaptor would I still be able to have the display at the highest resolution? I would appreciate any advice! Thanks in advance!!!
