Thank you for your help. I have a G4 and the monitor went. I bought a new/used 17" apple studio monitor. It has a ADC cord. What kind of adapter do I need. I have read it is the DVI, but how can I be sure that is where the monitor goes (in the DVI port) . Also, my old monitor connected the key board and ipod, etc... where do I connect those to now? Please help. Thank you!!
