Hi everybody, I'm gonna purchase the 27" iMac but I'm curious about an aspect of monitors I've never considered. The iMac has a contrast ratio of 1000:1. When I look at ads for TVs, whether it's LCDs or plasmas, the contrast ratios are significantly greater. Can the contrast ratios of TVs be compared directly to computer monitors? Is for example the 1000:1 on the iMac exactly equivalent to a 1000:1 specification on a TV? Thank you.
