I am wanting to hook my iMac G5 (iSight) to my 42" plasma screen, courtesy of the Mini-DVI adapter. I am aware of what cable I need to get (DVI-D, if I recall correctly), I am simply concerned with the achievable resolution. If any of you have hooked up your iMacs in this way, could you please inform me what resolutions you all have been able to achieve? My plaz can display up to 1080i. Thanks so much!
