I almost don't know where to begin, which heralds the arrival of my not knowing where to stop.
My favorite-ist monitor is an HP ZR24w 24" IPS CCFL backlight @ 350 nits, 1920 x 1200, (16:10) It's big, bright, and spot on in color.
Next comes an 8 year old Westinghouse (!) TN 1680 x 1050
It's bright, and the color is good enough to edit photos with. Best TN panel I've ever used. (Yes, the best, believe it or not).
I bought a Samsung 22" same resolution, with a pivot stand for vertical use. The viewing angle wasn't quite as good as the Westie, and the color balance was so way too green, I shoved it in a box, in the backroom, where it remains. Despite Samsung's reputation, the only thing I've ever gotten really good from them or Toshiba, was their old VCRs, which were stellar and wore like iron. This monitor forced me to buy the Dell to follow:
Number 3, is a Dell 23" IPS, 1080p which I use vertically on my call Techspot computer.
This is the "new" 6 bit IPS panel. It really isn't anywhere near as good as my HP. Dell is claiming 270 nits brightness, and (IMHO), it's kinda dull. The whites never "pop", and the brightness needs to be pegged. Although this is a CCFL backlight, I consider it to be a harbinger of the new cheapie IPS / LEDs. They're doubtless 6 bit panels, and on paper they aren't as bright as this one.
I also have an old Toyo 24" MVA 1920 x 1200 which is decent and gets pressed into service when I have to setup an extra desk top.
Then, I have an Acer G276HL Ddb, 27" 1080p, MVA LED @300 nits (!)
I grabbed this on sale @ $199.95, maybe 6 months ago.
(This Acer series should be decent, the 2 bills was a promo release price. It only has DVI, no HDMI, which obviously helped to bring the price down).
One day I really should pop this out of the box and see if it works. Or then again, maybe I don't want to find out, as the 30 day return period has long expired. Hell, it's liable to be out of warranty before I get it out and test it...
