I have taken a look at the relatively recent X-Bit Labs review of the LS221H and W2284F and decided that I wasn't recommending either right now.
LS221H: low response time but accompanied by RTC error, which pretty much ruins everything. I have recommended LCDs with RTC error before (many ViewSonics) and decided I wasn't going to do it again. It's not fun, folks, and I've had two monitors with pretty bad ghosting problems. Believe X-Bit Labs.
W2284F: not available in North American market which is a shame since this is the target of my recommendations. I don't know if that's going to have to change but for now I'd like my list to contain only North American-available monitors. Now that's not because I don't like other countries...I certainly enjoy the international folk that visit but I feel the US is the primary target of my thread. There are actually quite a few monitors available elsewhere that are decent and not available here, including Hazros. You are always free to ask in the thread personally but int'l -only LCDs won't be on the list.
I don't know if it's just me but there seems to be a drought of good LCDs lately so that's why activity has been low on updating the thread, except for the 2209WA which was a diamond in the rough.
I would consider recommending the Samsung 2233RZ although I really dislike its high price and the only redeeming feature it has is the 120 Hz (the 3D I don't care about so much), which in itself may be very difficult to utilize with all the games out there demanding very expensive video cards. I haven't seen any data on the LCD at all, either, besides the input lag data which I'm happy with (max 10 ms). It is yet another TN display with questionable benefits, really, for most people. It may be considered for the gaming section but probably nothing else. I didn't like that it was not available for sale standalone either, but I guess people will go to lengths for a true 120 Hz display.
I am on the fence about the LP2475w given all its uniformity problems, but regardless I want to leave it up at least so people know about it and if they are willing to take the risk.
Finding the "perfect" LCDs isn't easy but we can't start recommending everything out there just because it exists and it's "OK". There are certainly many LCDs that do meet my criteria and hopefully many to come. I am seeing a trend towards more PVA displays (note Samsung's recent 'cPVA' announcement) so I'm doing my best to lean away from the TN trend and I'm recommending as few TNs as I can.
Recommending monitors smaller than 22" has always been a crapshoot and I believe due to the dearth of reviews and market for these panels that the best route is to your local Best Buy, unless you can find the LP2065. As far as all the other 20" TNs go I'll never know if there's a difference between any of them because no one bothers to review them anymore.
Non-TN 22" panels are starting to appear, which is great. This will hopefully be followed by an influx of non-TN panels in the bigger sizes as well, which themselves are already being permeated by the cheap panel type.
I don't know whatever happened to the LG W3000H (S-IPS), but I can't find it available anywhere. AFAIK LG's entire lineup is TN right now and I wouldn't expect any more non-TN displays from LG Electronics USA. But at least LG Display seems to be manufacturing eIPS. I am pretty sure there was a 30" TN out there somewhere, too...
There are no stringent guidelines or standards to which I adhere when I put something on the list. I'll admit it goes off of intuition and maybe even what I feel like putting up there. It also goes off trust of the manufacturer. For instance, I am not too keen about recommending ViewSonic because of the poor menu system, DVI problems, and the fact that almost all of their monitors have RTC problems. I am quicker to recommend Dells because they have shown a decent track record of non-TN panels and great interface capabilities. BenQ is the same way; I love them. Samsung has been better lately and LG has put out some good TN panels. ASUS is decent but I haven't quite built the trust or respect for them yet and often lack good data on many of their LCDs. Acer is hit or miss but mostly targets the cheaper market, so, well, you know how that goes. HP is quite good as well except for the uniformity blunder with the LP2475w, which I really hope they're getting solved. Obviously some people don't have the problem. Gateway has been decent for the consumer market but isn't known for stellar image quality. I'm pretty quick to recommend any of NEC's pro line but give their consumer line the same "difficult eye" that I give other LCDs. Planar has quite consistently demonstrated good quality and DoubleSight isn't too bad (though I don't like the latter's warranty and service as much as Planar).

( Don't you love Samsung's new marketing campaign about "LED TVs"...well I'll save that for another rant...

Edit: I have noticed X-Bit did a review of the 2233rz so I'm giving that a good look.
