Response time isn't a fixed value. Different transitions give different results, and with current LCDs you can get anything between 2ms...10ms (for example) on the same panel.
This value is pretty much pointless now, like over 9000 Hz and other 100000000:1.
LCDs didn't improve the real response time in last years, despite stating ridiculously low figures.
Anyway, measuring the input lag in whole processing+panel time is much more useful.
Panel response time is not an indicator that it's somehow "better" anymore.

Even 120 and 240Hz is achieved by "overlapping" the pixel state, without waiting for a full previous transition to be completed. It means LCD is driven maximum at ~4 ms time for 240Hz. And there's no guarantee all pixels will be switched in such short time.
There's no room for a serious technical improvement here, only marketing. Like having a "2 ms" panel over "4 ms" will give you a whole new experience... But it's still the good old blurry LCD at the end.


Read my previous post again i updated it : http://forums.hdtvtest.co.uk/index.php?topic=9314.msg43870#msg43870

So what ? VA struggles heavy with highest transitions. [33ms+]



You are deviating from the subject with conspiracy theories.

The best you can get now is as shown in the image above an IPS with 10 ms for highest transitions and lag free [8 ms is invisible to our eye-brain system on 60Hz] for average and lowest transitions.

VA is around 10 ms for average transmissions, lag free for lowest, and the highest transitions suck badly starting at 33 ms for 1080p.

But new panels in 2015 should make these transitions lower for both VA & IPS.
The best solution now is IPS screen for gaming but you will lose big on contrast.

Based on what? They were supposed to be lower in 2011, in 2012, in 2013, etc. :lol:
Yet they pretty much were the same since 3D and 120/240Hz refresh was introduced.
These figures are limited by liquid crystals physical properties. You can't suddenly change them over year, there is a clear limit. And we're pretty much near it for years. There's no big room for improvement left.

That's why I play on plasmas. Not a bad solution with amazing deep contrast, low input lag and blur-free motion.
I don't get this whole LCD-centric thing. Discussing VA vs IPS pros and cons seems like a joke compared to best plasmas around.
Contrast? Viewing angles? Response time? C'mon, gimme a break. :rofl:

The limit can be usually found in monitors. So what is stopping TV makers to make them as fast as monitors ?

Plasma consumes to much energy to be sold in Europe. Actually lowering power consumption was the only thing [law] that forced panel makers to find quantum dots and other solutions like that, to potentially replace OLED.
