Hi Everyone, I am consdering trading in my G5 tower for a new iMac (of course I will wait until the line is updated, which may be next week). One thing is very important to me, however: the ability to support a second monitor in extended desktop mode. I think I recall somewhere reading that the iMac does not support extended desktop mode, but it does support mirroring, which makes no sense to me. Is this true? Also, if extended desktop is possible, would I be able to use my previous gen. 17" LCD studio display (clear lucite). I do have an ADC-DVI adapter. Thanks in advance for the help.
