I have a 22" samsung that I hook my macbook pro up to when I get home. I used it to edit photos, safari, email etc. My main issue is the clarity/sharpness of it. I feel as if I need a set of glasses to see it I think is supports up to 1680x1050 or so, so that's what I run it at but it still doesn't help. Im about to throw this thing out of the window. Seriously, it is about to go on craigslist or ebay and I'm just going to pick up a 20" acd or something. This thing is ridiculous.
