So, few questions. I'm about to buy one of these today, was just wanting some fast consultation. 1.) Are these displays still great? Good? Is there a better monitor out there for me? I'm going to be using this as an external display to my 27" iMac, reason I want it is for photo editing- true color and all of that stuff. Since my iMac is glossy. Will this be a good choice? Is this a good monitor for photo editing? 2.) So this is an "HD" display, did the 20" come in "HD"? I did a lot of research on buying around with these, and I've never seen a 20" advertised as HD, but saw the 23" advertised as HD multiple times. 3.) The one I'm buying today is in mint condition, except fo apparently there's a speck of dust locked behind the screen on the very top left corner. They say it isn't noticeable whatsoever really, and extremely hard to find, and that it's in the navigation bar. Knowing me, I'll probably always go to it once I see it. I'm buying this for 225 though, so that sounds like a decent deal, right? The monitor is in mint condition, other than that dust speck. Just a wandering buyer looking for some insight on a purchase. Any advice would be appreciated!
