Ok, I have a question for xtknight or anyone else that know anything about this. I've searched the thread but haven't come up with an answer. Number 1 recommendation for hardcore gaming is LG L227WT. The rt and input lag is said to be zero. The official spec for this monitor is 2ms response time, and here:
http://www.tftcentral.co.uk/reviews/lg_l227wt.htm the input lag is tested to be 9,4 in average. So, whutup with the zero image delay? Seriously, I wonder if this really is the same monitor with same panel, or if there is something I'm missing. If the image delay as you call it is zero, this may be monitor I want (for gaming). If not, I'm kinda looking at Iiyama ProLite E2201W or a CRT. I would really appreciate it if I could get some clarity about this.
One other thing. My current monitor is Hyundai L90D+. I've been trying to measure and improve my reaction time recently and therefore I'd like to know the image delay on this monitor. Anyone who knows? I've been googling this lilke crazy but haven't come up with anything at all.
Anyway, thanks for a really great thread. Vey much appreciated. Especially the info on input lag in these times when manufacturers doesn't excactly tell us anything about that.
Edit: Oh, my bad. I couldn't browse the thread properly earlier. Don't know why, maybe something with firefox. Anyway, reading through it know.
Edit: Spelling
prad reported the L227WT as having zero input lag, and even a photo of it.

Therefore, this is where the info in the OP came from. Once again though the fact that input lag varies among different sites is nothing new. I'm not sure why it happens, it could be a video card configuration issue, or someone measuring it wrong, but the measurements tend to coincide by around a frame.
If you look at DigitalVersus they have terrible ratings for the L227WT's input lag:

Why is anyone's guess. From the subjective reviews I've heard, the L227WT is great for gaming.
Another thing is that while LCDs shouldn't have even a frame or two of lag, you have to realize that that amount of it is simply hard to notice for anyone. Hence why manufacturers keep putting out LCDs with lag. If nobody bought them, they just wouldn't be making them anymore. The 60 Hz refresh rate of an LCD is the first thing that makes it feel slower compared to the CRT.
I guess the severity of the problem is akin to saying that your calculator takes an extra second to turn on versus your old one. It's just something that doesn't cause any discomfort when we're talking two frames or less of input lag. Three or higher begins to be noticeable, and especially four or higher.
Get an LCD with an avg (2 frame) or low amount (<2 frames) of input lag for a store and give it the time of day. Maybe you will like it. Even knowing the L227WT has around zero-one frame of lag from reputable sources, it will remain on my Gaming list.
If you want an LCD that's as fast as a CRT, you will have to wait for more technological advances that keep every crystal transition to under 1 millisecond, and implement flicker-free black frame insertion. Currently, the best LCDs can not transition any faster than 6 ms for every single transition, and BFI has a 60 Hz CRT-like flicker.
Will those advances come and when? Maybe with blue phase LCD crystals, which aren't due out for at least another couple of years. Maybe with color filter-less LCDs which probably won't ever see the light of day. With OLED? Yes, except BFI or motion estimation still needs to be implemented in order to provide an image as smooth as a CRT because of retinal persistence.
You will see response time advancements such as 180-240 Hz and higher-quality motion estimation in LCD TVs [first], but there is no guarantee they will ever reach the world of LCD monitors before OLED/SEDs assume control of the market.
For now, it is best to assume that your eyes are as anyone else's, and to accept the downfalls of current LCD technology. If it becomes an impediment to your favorite hobby it is time to lug in the 50lb monster again. Plopping down $700 for a monitor that doesn't have viewing angle problems or a slow update rate is fiscal diarrhea. You bet I wish I could do something about that.
In addition to that, I have to say, I hope you find the right LCD. You seem to have already been researching it (L227WT). My crystal ball (80% accuracy rate!) says it should be as fast or faster than your Hyundai.
It is important not to relate LCD response times to ping times you see in a game. Ping times measure the round-trip time it takes for one packet to reach the server until another packet comes back to the client. To get even halfway even with the way input lag is measured, you would have to divide the ping in half. Additionally, with a ping>0, the network engine of the game client employs estimation to determine where the "player" intended to be. Sometimes this estimation can be jerky and cause a sensation of lack of control. Game ping has stuff in the fine print that the flat input lag time of LCDs does not. You may be able to feel the game client's flawed motion estimation far before you would notice an offset in response. The motion estimation I talk of in games modifies the player's movements. "Motion estimation" in video terms ("video smoothing" in video codecs, or "Motion Picture Accelerator", MPA, in LCDs) attempts to model the same object as it moves across 2 frames and creates an intermediate frame to ease motion.
