I'm looking at getting the Dell UltraSharp 2407FP monitor to serve as a secondary monitor for the iMac 24. my assumption is that all I would need for this happen, aside from purchasing the monitor, is the Apple Mini-DVI to DVI Adapter. Is this correct? I may also end up using the secondary monitor from time to time for my MBP, but fortunately the MBP already is equipped with the DVI out standard port.
