The LG, Asus and HP ZR22w have panels that use 6-bit colour depth with A-FRC to produce 16.7m colours. On the whole this is not a problem, and you wouldn't notice it in most cases but it can cause banding, which is not what you want when editing images, so it's something to look out for.

Now thinking HP ZR24w, is the added 2" worth the extra 120 bucks?
The HP ZR24w is a true 8-bit monitor which is preferable for colour critical work, so in itself yes, it would be worth the extra money. However, the ZR24w seems to have a few problems of its own. tftcentral reported poor black depths & contrast ratio, and Prad reported a minimum luminance level of 147 cd/m2 which is way too high.
So, based on the reviews the HP ZR22w might be the best bang for the buck.

Not just 2", but 1600x1200 vs 1600x1080 -- more vertical pixels. I usually find myself cramped vertically more often than horizontally. YMMV.
You mean 1900x1200 vs 1900x1080 of course.
I agree, it is nice to have more pixels vertically. It's what I wanted when I was shopping for a new monitor but I ended up with a 16:9 monitor and couldn't be happier.
