They are identical, but the stands are pretty short. They do tilt, although what I've found in the past is that I don't want them tilted, since that creates gaps between the monitors. The monitors I have right now are much older - they're 17" 4:3 style - and I have them on a stand I built a long while back, which is tilted. It would be easiest to just go that way again.
Funny to realize that I paid about $350 per 17" 1280x1024 monitor when I got these... and paid $230 per 22" monitor a couple days ago. :) WHY ISN'T MY 286 STILL WORTH THE TWO GRAND I PAID FOR IT??? ;)
I'll show you just how silly things are...
Ok, my 3 Samsung 245BW 24"
#1: Bought at Xmas 2007 for $438
#2: Bought in May 2008 for $380
#3: Bought in July 2008 for $312 (refurb)
My bet is 24" will be new for $250-300 range soon. With 26-28" LCDs taking over the old 24" price point, 24" will probably take on the 22" LCD price point.
