I have a PowerMac G4 with a GeForce 4 MX 64MB that I know supports two monitors at a time. It has one ADC port and one VGA port. I have a 17" Apple Studio Display (ADC) and recently bought a used 15" Apple Studio Display (ADC). The 15" I bought came with an ADC => DVI converter (retail $99). Will something like this let me use that monitor fine with my PowerMac?
