I got a Hitachi 1600x1200 off ebay 2 years ago for £260. It has been great for poker but it has had some glitches (what do you expect for that price). Anyway I have just replaced it 2 weeks ago with a dell 30", 2560x1600. Hmmmmm. And as the Hitachi came with a 3 year warranty I'm going to see if they will do anything for me.
1600x1200 was the best resolution for poker, but now with widescreen monitors so cheap, its as good to get 2 widescreen 17" in portrait next to each other, and you get more screen for doing other things too. Widescreen in landscape doesn't lend itself too well to poker tables though.
You'll love 4 tables on that monitor, no more overlapping
