"edit"
here's your proof than an LCD is capable of doing other refreshes than just 60hz
http://www.yslcd.com.tw/docs/product/T260XW02 V.C.pdf
page 16, section 7 subsection 7.1
clearly stats that it is capable of refresh from 47hz to 63hz Vertical. now that may or may not be the spec sheet for the panel in the D9000 LCD but the panel in the D9000 is a AU panel, and that spec sheet clearly states that AU is capable and does produce panel's with variable vertical refreshes
That's about *input*, title says: "Timing characteristics of LCD module input signals".
"2nd edit"
To further Calamity's and my arguement here is a quote from Agreed on the AVS forums which explains this much better than i ever could.
Calamity could have been under temporary illusion,
I think we are yet to hear his final conclusion,
but it seems fair to agree, that he can be a referee.
Fact 1: LCDs don't have refresh rates in the same sense that other technologies do...
Of course they do, there is no other way to depict motion, except for vector monitors and holograms. LCDs could possibly update only those pixels that changed since last frame, and by doing so completely skew the meaning of "frames per second", but when the camera pans and when the screen scrolls then often all the pixels change every frame, thus it all really must come down to same old thing - "frame by frame", amount of which in one second is known as 'frame rate' and is exactly what defines the very concept of "animation" itself, either live television broadcast, cartoon or movie, on CRT, LCD or via Projector, digital or analog signal, recorded on VHS or DVD, it's always the same, it's the only way.
So, fact 2: If the video processing technology feeding the LCD tells them to change state every 1/24ths of a second (okay, 1/23.97th, whatever), they're happy to do so. This is exactly what goes on in 120hz TVs doing a 5:5 pulldown anyway, from the LCD panel's perspective. Just because the video processor deals with it in terms of "okay do 5 repeats of this frame, now 5 of this frame, now 5 of this frame" and so on until it has served up 120 frames in a second doesn't mean the LCD is serving up 5 repeats then 5 repeats then 5 repeats - it just stays the same for all 5 of those frames that it is given, for a total of 24 actual state changes in a second.
You are confusing frame rate conversion with syncing. If the display can refresh at exact rate as video feed then there are no any repeated or skipped frames, no any fractions either, it's 1:1. Also, it is something completely different to convert frame rates when they are whole multiples, but if they are not, like in our case, then there will be choppiness and/or tearing.
Finally fact 3: The panel itself does not impose a technological limitation that would prevent 24p content from being shown at 24hz. The only question is what the actual supporting hardware and software in the TV itself can feed the screen.
It's not important where is the limitation, and you are haste to conclude that's not the display itself. Of course liquid crystals have some operational range, but that's "safe range", or maximum capability under best and worse case scenario, still none of that says anything about how the final assembly and complete products actually work.

http://www.yslcd.com.tw/docs/product/T260XW01 V.8.pdf another model
page 12 section 3 subsection 3.3
That's about *input* again, title says: "3-3 Input Timing Specifications".
http://www.yslcd.com.tw/docs/product/T260XW03 V.3.pdf and yet another model
page 12 section 3 subsection 3.3
That's about *input* again, it says: "This is the signal timing required at the input..."
and since we don't want anyone saying I'm playing favorites with AoU here's a Samsung model picket at random
http://www.yslcd.com.tw/docs/product/LTA230W1-L07.pdf
page 10 section 3 subsection 3.1
That's about *input* ("connector") again, it says: "The connector for display data & timing signal..."
you said you could never find any proof that an LCD could refresh at any other rate that 60hz and yet in less than 30mins of searching i found 4 manufacture spec sheets one picked completely randomly that prove otherwise.
No, I did not say that, and no you did not find any evidence any LCD can sync to some range of variable refresh rates. All you did is confirm what we already knew, which is that LCDs are made to replace CRTs and therefore are compatible with the same INPUT signal, but that has nothing to do with how many frames they can actually OUTPUT on their displays.
So quite spouting off your wikinonsence it's not the panel's that are incapable of different refresh rates, it the monitor manufactures that restrict said refresh rates if 98% of consumes will never use any other refresh rate than 60hz why spend the extra money on the circuitry to feed that signal to the panel, when they can make a few monitor's that will feed the signal to the panel and charge a hefty premium for it ALA D9000 lcd
I repeat, all the "evidence" you presented is only about INPUT signal, not OUTPUT refresh rate of the screen itself. -- You know, at the beginning LCDs were doing only 15fps, some 20, then 30, and it's only rather recently they got them up to 60 and eventually above 120fps, but the whole time they could sure take this same variable INPUT, the same as CRT could. And somehow people didn't notice anything even then, but this blindness is not of medical origin, it is a manifestation of what is called "planned obsolescence" - the desire on the part of a consumer.. to own something.. a little newer.. a little sooner.. than it's necessary. **The Light Bulb Conspiracy:
