is that 20" or 21", it looks 21" but 20" viewable.

I can't seem to get to the link you posted but I don't think that monitor is really 16ms. We would have heard that the technology was available to make large LCDs that quick. I have heard just the opposite.

Plus, I've come across other information in the past that LG is misslabeling their LCD screens. Using the best figures instead of "typical" response rates. I'm almost positive this monitor is 25ms at the best.

If you find out otherwise PLEASE let us know. I'd snag up a 16ms 20" LCD in a second...it's the purchase I'm most interested in now.

______________________

No telling but I noticed some other older models like the LM201U03 that were listed at 25ms. The MP thing prolly means mass production begins at the date listed. The 20.1" seems to already be in mass production but not on the market since the ones on the market list "now" as the MP date.

Yea gotta be careful of LCDs boasting 16ms response times. As doomgazer has illistrated these resp. times are at 8 bit colour, as soom as you turn the colour up to 16 or 32 bit the response time takes a big hit. Which is not really acceptable.

AFAIK it means 8bit per color(RGB) and that is 24bit true colors.
16ms spec. usually means black to white and white to black again pixel response. That is fastes response and in fact not typical.

B-W rt is the not fastest, if u want speed check out gray to black, those are the fastest. When manufacturers give the rt, generally it's a time rise and time fall, so b-w-b, and is used as a standard measurement in comparison. If LG did pull something, giving b-w-b wold be legit, but instead it'd pull something like g-b response time.
To avoid confusion, the reason we say 32 bit color is b/c there are an extra 8 bits as alpha channels, disregard those for the now.

That’s weird...
AFAIK manufacturers get their "typical response time" (rt+ft) when color change

a. rt for “Rise time”
from 10% signal (above “clear black”) to 90% signal (bellow “full white”)-(rt)

b. and then back ft for “fall time”:
from 90% signal (bellow “full white”) to 10% signal (above “clear black”)-(ft)

But in fact time is taken when signal travels from 0%(b)->100%(w)->0%(b) full signal change. I always thought that it is fastest “color” change for LCD pixel(?)!

Well, maybe I’m wrong :-(

Not sure if it's this one, but I remember checking out the specs of an LG 20"er that had a 16ms listed on one site and 25ms listed on another. These sites were both LG's, one US and one somewhere in Europe. It's possible the same exact model could have different response times if there were different panels, but I still think it's sketch...

They could be taking a shortcut. What happens is to get to only a partial black it takes more time, but, to go from a partial black (like say 50% grey) and then go to a black, you apply full power. It's like applying same power as u would w-b, but having to shift less.

ok...got the Finland´s LG importer to phone and said
that they have en error in web tech details...LG´s
new models has 25ms time not 16ms...and forwarded information to their web administrative....
