Viewsonic's VP930b display has a 16, 8, 3 or 2 millisecond response time depending on which Viewsonic representative you speak to and during which purchasing season
The same company that brought you the 2ms response time LCD brings you another astonishing miracle of science and advertising

Just when you thought the LCD market couldn't stoop any lower, Viewsonic manages to do it again.  Several blogs are reporting about an internal memo from the company with regard to the upcoming "1ms" response time LCDs to be announced later this year.  The document claims that with a combination of OverDrive, Dynamic Structure and Amplified Impulse technologies, this year's new displays from Viewsonic will carry a 1ms gray to gray response time.

Gray to Gray response times are traditionally the average time it takes the LCD crystal to twist from one state to another.  Specifically, the Viewsonic 1ms LCD panels use a 6-bit twisted nematic LCD panel; each subpixel on the display is capable of 64 states.  Akin to a window shade, the further the liquid crystal twists, the more light passes through the display. 

Viewsonic's current displays advertise 2 and 4 millisecond response times on gray to gray (GTG) scales over 256 data points.  What the company does not disclose is the actual gray to gray states -- meaning the GTG response time may only represent the twisting of the liquid crystals from the 1st to the 2nd subpixel state, or the 2nd to the 3rd, etc.  In essence, Viewsonic's 1ms response time is the measure of the liquid crystal twisting from #FF to #FE. 
Viewsonic, like most display companies, does not manufacturer its own LCD panels.  Viewsonic's current LCD provider for high response time LCDs, AU Optoelectronics, only manufacturers panels with 12ms and 16ms advertised response times.  How Viewsonic manages to bypass the laws of physics to twist liquid crystals faster than the manufacturer by adding a digital signal processor remains to be seen.

ok... let's take the full quote:
"The document claims that with a combination of OverDrive, Dynamic Structure and Amplified Impulse technologies, this year's new displays from Viewsonic will carry a 1ms gray to gray response time."

Where does it mention a DSP being responsible for the "1ms"?
That's just a statement from the writer, not Viewsonic.

Then again, I'm not trying to "save" Viewsonic from anything... just that they should be allowed to launch their product and only THEN we can bash it if there's a reason to.

First of all, it depends what that time means: GTG, etc (just like you said).

So if they can do a 1ms response time at whatever test the invent, are they lying? No. Are they not telling the whole truth? Also no - but then, so do all other panels out there.

Let's wait till such a panel comes out, and I have no doubt it will be tested by every major review site - and then we'll now how this "1ms" panel really means in the real world.

tomshardware also do not like the fake low ?ms and are biased against it!
and if you think this ironic remark is biased then what you will say about Mike at The Inquirer ;-D
