I've noticed that many manufacturers are now stating the "grey-to-grey" spec of their LCDs and it's always some "blazing fast" response time of 12ms, 8ms or even 6ms. Since it's obvious that this is impossible, I wonder what methods do they use to mislead their customers once again? Does anyone know what's the "official" method of measuring this grey to grey response time, if there is one? Do they only take the rise time into account? If so, between what shades of grey do they measure those transitions? I'm not interested in any of those monitors, I'm just trying to find out how relevant is this "grey to grey" information that manufacturers started to use. I guess thanks to the sites like xbitlabs many people have found out that its the grey to grey response time that matters so now they have a spec for that too which it seems is even more useless that the standard method of measurement.

Grey-to-grey response time specs?

I have not looked in to this as of yet, but IMO this grey-to-grey response time is a load of crock to confuse people. I would always look at the total response time and not this grey-to-grey crap for over all performance...
In the case of xVA panels, a low grey to grey response time is huge. On a normal xVA panel, the grey to grey response time can be as high as 100ms, even if the typical response time is quoted as 20ms. That's why I'm so interested in the Viewsonic VP191. It seems to have the advantages of a xVA panel with a decent response time.
Yeah, that's why I'm really interested in the way they measure this. I see some people are going crazy over all those new "8ms grey-to-grey" monitors and don't realize this is just another maketing trick. The fastest LCDs on the market hit 8-10ms but only like 1% of the time and only on black-to-white transitions which is ALWAYS the best case scenario. The real grey-to-grey transitions may take up to 300% of the time of the stated response time so its kind of a mistery to me how can manufacturers claim their grey-to-grey response time is LOWER than black-to-white 
What type of panel does it use? I wouldn't be sure about all those specs. Sometimes, manufacturers change their panel from MVA to TN and leave their old specs like wide viewing angles and high contrast and just change the response time to a lower number. It wouldn't suprise me if that was the case with Viewsonic too.slpaulson said:
