Choosing a widescreen LCD
I have been comfortable on my 3x17" Samsung lcd's (see this post for a writeup on my panorama) but am looking to move to larger screens. At the moment I'm considering the upgrade to two 21" or 22" Samsung's; the 215TW or 225bw respectively.
The 215TW is a couple hundred dollars more but has extra inputs and supports PiP (Picture in Picture). Whilst handy, it's not a deciding factor for me. The larger screen size of the 22" is always nice for games and movies (even if it is only an inch). The dot pitch is marginally better on the 215TW (which is what you would expect on a smaller screen) that has had a chance to be refined somewhat. It just means you would have to sit the 22" back a few cm to not notice the larger pixel size (0.282mm). Since it's a larger screen, that's not a problem. One good thing to note is both models use true 8bit panels equating to 16.7 million colours. Cheaper lcd's sometimes use 6bit panels, which I think use 3bit dithering.
Nearly every brand 21" and 22" LCD I have seen is still using the 1680x1050 (16:10). It's cheaper to produce and keeps the cost down from moving to 16:9 on the higher resolution like 1920xSomething :).
You generally find the larger the panel the lower the quality as they are more expensive to produce. As competition becomes more competitive, you generally find each manufacturer tweak and optimise their panels. 17" and 19" lcd's are now very common place and are extremely well made from most companies now. Backlight bleeding, dead/bright pixels, uneven back lighting, poor viewing angles etc. are a thing of the past. As you progress up the size scale they tend to get a bit worse. Backlight bleeding on larger panels is more noticeable, uneven back lighting and sometimes smaller viewing angles (160/160 for instance) become more common.
My 172x Samsung monitors are rated at 12ms which seems quite high today. But I still game with them fine. You do get some motion blurring in fps games but the quality of the image is still superb. The 21" lcd mentioned is rated at 8ms GtoG and the 22" is rated at 5ms GtoG (Grey to Grey). Motion blurring should be almost non existent.
I'm almost ready to purchase two 225BW's but am a little weary on the backlight bleeding problems I have been reading about. From what people have been reporting it seems particularly prominent in this model.
Chi Mei are one of the main companies producing 22" panels at the moment. Samsung might be producing a small amount. Some people have cracked open the hood of the 225BW and reported seeing either a Chi Mei Optoelectronics M220Z1-L01 panel or Samsung's own LTM220M1 (which is supposedly very similar). I've read that Acer and Dell's 22" models are also using the same Optoelectronics panel. This may or may not be the case now. However, the back light bleeding is cropping up in a lot of the 22" lcd's at the moment for this reason (many manufactures are using the same panel at the moment). Some people have been lucky reporting very little bleeding, whilst others have reported terrible bleeding to the point of making the monitor unusable for most tasks.
I'm a big fan of Samsung and they have excellent service. I've never had to ring them for any of my lcd's as I never had any problems (and still don't). But a friend of mine did and they do door to door delivery of a new monitor no questions asked. Most Samsung lcd's come with a 3 year warranty.
Another friend of mine has 2x215TW and they are very nice. If I do shy away from the 225BW I'll be getting two of those. I have until next week to decide when stores begin to open back up.

I have a 24" Dell, and the quality is exceptional. If there smaller LCDs use the same parts I'd rate them highly recommended. Don't know official viewing angle, but I can see it from the side :) Much better than the newer BenQ 17"s my family have at home, but I guess that will teach them for buying crap without asking me...
Glad to hear you're 24" turned out alright :) I'll post back with my thoughts on whichever Samsung model I decide to order next week.
The 172X is sold as a "12ms" panel, but keep in mind that this is a Black-White-Black rating. That said, it's only a 6-bit panel (the colour on it certainly leaves a lot to be desired). BenQ/AU-Optronics sell theirs these days as 8ms/6ms/4ms etc, but that's Grey-to-Grey. (as you mentioned) In other words, they "cheat" on marketing by measuring G-G timing, not B-W-B. 8ms G-G can be as much as 35ms B-W-B.
The other thing to consider in gaming is whether you're using DVI or DSub. This is important because most cards will use blitting, which results in the same kind of tearing as you might see from overheating cards, rather than the ghosting effects you might see on LCDs with a higher latency.
Another thing to perhaps consider would be a Dell 30" monitor. However, to power this at 2560, you need a dual-link DVI port. The Apple MacBook Pro has this,if you feel like getting a new notebook :D
Dell are also releasing a new FP27xx monitor soon, which though larger than the 2407, still runs at 1920x1280.
The obvious disadvantage to having a higher resolution on the monitor is that having to run things at the native resolution means needing a beefier graphics card. Reason I mention this: Supreme commander. Even a 7900GT struggles.
I'm still using a 172X, since my other systems are a BMP and a 20" iMac. Personally, I would go with a single larger monitor, but that's mostly because Mac OSX handles multiple monitors and desktops very differently to the way Windows handles it.
Just something to consider.
I was going to buy a samsung 225bw but im really not sure about it anymore cause of the backlight bleeding issues it seems to have. Of course every 22 inch ws monitor has the same issues since they all contain the same panel, but the samsung has many more features over other brands.
The 215tw is hot but it is about $100 pricier and some a lot of options that i would never use, like it has in built speakers :S who uses their lcd speakers? :S
Now im torn whether to grab a 20 inch that i know is better quality, grab a 22 inch that i THINK will bother me cause of the backlight bleeding, or wait for samsung to make their own 22 inch offering : http://english.chosun.com/w21data/html/news/200612/200612200033.html
but who knows how much that will cost.
Ill prob just grab a samsung 225bw and shut the hell up about bleeding =[

the 226bw is said to be coming out real soon. It claims to fix many of the problems of the 225bw like backlight bleeding.
The plus side os the 226bw is that its a samsung made panel rather than chimei and has better specs.
I might wait to see what the price of this monitor is at before i grab the 225bw.
Cant edit my comment =[
The 226 does not have a height adjustable screen. I got no idea why they wouldnt include one.
