First off I wanted to say this is a great thread and a real benefit to the community. I have been reading it for a while now since I have started thinking about a new moniter for the last month. I had a few questions that perhaps you or one of the other people in this thread can answer.
____.1a
I currently own a Dell 2005FPW. When I first bought it 2 years ago I went through 2 RMAs until I got one that didn't have the backlight bleed so no problems there. What I wanted to ask about is an increase in "afterimage" that I have been noticing. Not ghosting mind you but more like: I have windowed document with a lot of white open for maybe 2-3 minutes and then I switch to a dark colored image or my desktop background and I see faint outline of the document on my screen for maybe 40 seconds until it finally fades away. Do you have an idea what this is? Is my monitor starting to die? It wasn't always like this and I don't notice anything like that when I move my picture quickly such as playing games but on web surfing its slightly annoying.
This is called "image retention" and it is especially common on S-IPS LCD monitors like yours. It may be an indication of the crystals starting to get old and cranky and just not wanting to move. Sometimes prolonged use may cause this so I'd advise leaving it off for 48 hours (if that's possible) and seeing if the situation improves.
____.1b
I was always told the 2005FPW was a pretty decent monitor. Ignoring the problem I mentioned in 1a, do you think I really stand to benefit at all from moving to a new 22"-24" widescreen? My current moniter does technically meet my needs already of mostly gaming and some movie watching/web surfing.
Oh I think it would be worth it to move to an 8-bit 24" widescreen, but you may be disappointed by a 6-bit 22" display, because your current 2005FPW has great 8-bit color depth already. 8-bit 22" displays do not exist, in addition 22" displays have a lot more viewing angle problems than what you're already used to with the 2005FPW.
____.2a
You mentioned that you are not adding the Samsung 226BW because of the 3-way panel lottery but considering that they only differ in color accuracy and there are now reviews for each version which guide you on how to correct that difference, do you think its worth reconsidering for your list? If you were to place it on your list, where would you place it? Gaming? Multimedia? Xth place?
You know, you bring up a really good point there. I am trying to make a page for the 226BW on my site right now, and I think that we can make that work. I intend to not only recommend the best LCDs but to make sure people get the most out of what they have. A major problem with the AU Optronics and Chi Mei panels is simply "out-of-the-box" accuracy. The AU Optronics P-MVA 19" I have next to me suffers from the same thing, but after calibration it sure shows its true colors, no pun intended. So yes I think I can make that work, and in each category it would be one below the LG L226WT whereever it may exist. Nobody can deny that the LG is still a more "sure" choice. A time estimate for when I will have the Samsung up there and all the pages I need to "coordinate" the effort, I'm hoping sometime this coming weekend.
____.3
All the 22" panels seem to be really fast TNs at 1680x1050 and all the 24" panels seem like slower PVA/MVA panels at 1900x1200. Do you think there are any compromises coming in the future like a fast TN 24" at 1900x1200 or a slower PVA/MVA 22" at 1680x1050? I like the idea of a 22"-24" but each size seems to make for compromises. Bigger size + Bigger res + Better Colors [vs] Big size + Same res + Faster response.
Some upcoming CMO panels were discussed on pg. 2 (depends on your posts-per-page settings) of this thread:

It doesn't seem like there will be any MVA-based or 8-bit 22" LCDs.
24" TNs will make headway with regards to response time and probably input lag, too. The main reason the 22"s are rather low on input lag is their lack of RTC and the ~16ms buffer associated with that feature. 24" TNs may be able to do without RTC too although due to lower pixel pitch (and thus smaller cell gap) than comparable 22" TNs, I believe they will be slightly slower.

I was always told that refresh rate has no effect on LCDs and yet I hear about 100Hz LCDs to come out in the near future. I see 100Hz LCD TVs available for purchase already in other countries. If I remember right, they are not truly 100Hz but use an alternating black/actual image to fix "afterglow"(?). Do you know if we will see these in the near future? I read these TVs "look" better in high speed action. Do you think they are worth waiting for?
There are tons of details about these LCDs on
BeHardware.com if you want to look in their Monitors section. Keywords include Samsung's "MPA" (Motion Picture Acceleration), "RTA" (Response Time Acceleration), and BenQ's "BFI" (Blank Frame Insertion). If it has to do with MPA/RTA/BFI it's on BeHardware.
Basically though they take a 60 Hz image and make it 120 Hz somehow, but 120 Hz is not being input to the LCD from the graphics adapter; only a 60 Hz physical signal is being sent. A 120 Hz signal is then extrapolated by either inserting blank frames, or by estimating the motion (rather unreliable technique), much like a video compression codec (e.g. MPEG-4 AVC) would with a 4x4 or 8x8 search. They have managed to drive the crystals at higher than 60 Hz also. One more technique is by using 16 horizontally stacked switchable backlights. They just turn one off after the other, roughly estimating the raster motion of a CRT's electron gun. This blanking helps wipe your retinal persistence of the image that was last in the place of the blanking. I hope that helps.
Are they worth waiting for? Well, there are a couple that already exist (TVs and monitors). The BenQ FP241WZ implements BFI (or similar) technology with 3 possible presets and an 'OFF' setting, if I remember properly. Here is a link:
http://www.behardware.com/articles/646-...q-fp241wz-1rst-lcd-with-screening.html
I believe manufacturers are more focused on getting wide-gamut CCFLs and LED backlights to market than reducing response time, though. Reducing response time does have some fairly diminishing returns.
