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.

Call me old-fashioned.....

... but I think that for video/photo color-matching and PC gaming, I shall continue to enjoy my high-resolution Hitachi CRTs just a little while longer. No fussing over response-time, color-accuracy, scan-rates etc. LCDs are conveniently compact and have their place in non-critical applications, but for performance-critical viewing they still have a long way to go.

I agree 100%. I still greatly enjoy my 21" FD Trinitron CRT. It may weigh alot and take up a little extra desktop space, but the performance and flexibility can't be matched by the LCD's out there right now. This is especially true in games. I can choose which resolution will run the smoothest and look the best in each game.

The only problem is, the market is gearing toward almost exclusively making LCD's. So, I just have to hope that my old-fashioned CRT keeps chugging along, at least until they come up with something better than the current LCD technology. :-)

I also agree!

Personally, I stay away from desktop LCDs altogether. Even after all these years of LCD design improvements, I've yet to look at one that I would prefer using over my 6-year-old Hitachi CRT.

I share the same sentiment with the author concerning how twisted LCD marketing is these days. I wish the manufacturers would put out accurate numbers about their products, but being truthful would probably hurt their sales.

As far as the display market's direction, it would seem like the CRT's outlook is actually quite well. Anand published a CES article that covered Canon/Toshiba's SED technology a month ago: http://www.anandtech.com/tradeshows/showdoc.aspx?i...

Read that if you haven't already, but I believe that this technology will cause quite a decline in the popularity of desktop LCDs.

Damn kids and their Damn idiotic lack of knowledge.


I run my 21" Triniton CRT @ 1920x1440 @ 71hz.

I went out a few months ago to try and find a good LCD monitor that dosen't have all this widescreen shit, and buy it because I thought it was time to move up. Whats this? I couldn't find ONE good quality high resolution monitor that could display at 2048x1536/1920x1440 at a decent refresh rate. This plain pissed me off after moving 3 feet and going to my Inspiron 9300 @ 1920x1200 on a 17" panel.

The fact that companies keep doing this shit and keep falsely advertising their numbers only ensures that I will stick to the superiority. As someone else previously said, for all regular things, LCDs are fine. For professional high end applications that demand a good resolution, good response rate, and so on, CRTs will be the way to go, unless LCD makers pull their head out their ass.

Just sickening, finding a 20.1" panel @ 1600x1200.

You might mean "high resolution" rather than "good resolution". Many professionals that actually need the resolution also want pixel precision, not blurred crap like CRTs produce. A good CRT is of course much better than a poor one but you cannot get per pixel accuracy out of a a CRT, including your trinitron, at 1920 x 1440. 71 Hz? YUCK! The flicker would be so horrible it would give anyone with good eyes a headache.

The SED technology is interesting, but still leaves the problem of a native resolution (if I am reading that correctly). It could be great for TV technology, but in PC games, you are still stuck with a native resolution.

Yeah, I hate LCD/DLP because of native resolution. I think ThinCRT will be the real future. I thought SED didn't have native resolution?

Unfortunatly, cannon and toshiba are planning mainly to make tv sets, not computer monitors using the technology, possibly because the individual pixels are to large to make a smaller sized monitor that has sufficient resolution. To find anything else you want about SEDs look at http://answers.google.com/answers/threadview?id=52...

I'm with you on that, the 19" Viewsonic CRT (Aperture Grille) that I recently aquired does a max 2048x1536 res and my desktop res 1280x1024 at 100 Hz. I couldn't be happier. The ultrabright tech is awesome for games. It is way more flexible on resolutions than any LCD on market. Though I respect other people's opinions on the space savings afforded by a LCD, I personally don't mind giving up a little space for exceptional performance.
