Okay, with the lowered prices of the Cinema Displays, I'm debating getting one. My question is, what's the refresh rate on it compared to a CRT? I always use a CRT for playback with video, simply due to bad experiences with other non-mac lcds. Has anyone ever noticed reduced quality with the cinema display compared to using a CRT? I'd get the 20", due to the price and the fact I work in SD-only anyway. It'd serve as the external monitor on my Powerbook. Thanks.
