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.

In most cases I would agree that a news service should be unbiased ... but in this particular case I certainly will not be wagging a finger at Kristopher.

If Viewsonic advertises this panel with a ubiquitous 1ms response time, then they absolutely should get their hands slapped for misrepresenting their product.

Whose fault is it that there are so many "response time" specifications (TrTf, Tr, grey-to-grey Tr, et al)? The industry for not having a standard, the generally confused customer, or companies taking advantage of the previous two? I fault the latter and propose three cheers for Kristopher for defending the middle.

Frankly, I am grateful for news writers who don't simply regurgitate the slop contained in most PR drivel, but instead call companies out when they make far fetched claims.

OK, now that I'm all the way out on the end of the plank here, I will acknowledge that this news bit is really just a rumor and so I shouldn't be so callous towards Viewsonic. They were the unfortunate recipients of this minirant which was the culmination of my frustration with the industry as a whole for their sloppy specsmanship.

I completely agree.

It was just the "ironic" tone, that put me off a little.

There were a thousand other ways to say it was a "dubious" claim other than to "break the laws of physics".

I understand he might have a long story going back on similar issues, and have his right to dislike Viewsonic. But when writing for such a larger audience, he should do so in a proper way.

But enough of all this, I like Kris news... I was just stating MHO. :)

Well it could still break the laws of physics because nothing is free. If you state a list of specs then argue there's a way to better ONE of them, the other specs still have to remain true, even the warranty period (actually MTBF) has to be considered.


Then there's the other "physics" involved, that just because "some" panel can be overdriven to gain speed, that doesn't necessarily mean the specific panel they used, has this headroom.
