Description : Hi-Def/Hi-Res screen required for HD editing?
Last Answer : the 24in imac will give you a resolution of 1920×1200 which is greater than Blu Ray/1080P. The 20in models are 1680×1050, which really isn’t too far off. If you wanted to, you could attach a 24in monitor to the iMac and run video to it’s fullest resolution on it.
