NEC CRVD-42DWX+ curved display  (Source: NEC)
NEC and Alienware seem to be pulling form the same playbook

At CES 2008 last week Alienware announced a curved computer display geared for gamers and making people more productive through more screen space while working on a computer.

NEC must feel that the market for long, curved displays is a up and coming category as it announced its own curved display called the NEC CRVD-42DWX+. The NEC display has a screen resolution of 2880 x 900 with a response time of under 0.02 milliseconds. The NTSC color gamut the display is capable of is 170% and the dynamic range is 12-bit. In all the display can reproduce 68.7 billion colors.

NEC spokeswomen emphasized that the Alienware prototype and the NEC CRVD-42DWX+ "have nothing to do with each other."

While NEC claims the two displays share no common manufacturer, both displays are built with the same bezel and housing. Both displays use two LED-backlit DLP images to "stitch" the 2880 pixel-wide image across the curved display as well.  The likelihood that these two displays are not made in the same place would be an unusually odd coincidence.

The display has a typical brightness of 350 nits with a contrast ratio greater than 10,000:1. The screen has an aspect ratio of 3.2:1 and weighs 25 pounds without a stand. The overall dimensions of the screen are 40.4-inches wide x 12.6-inches high.

NEC declined to comment on pricing or availability of the display at this time.  However, given the high-markup nature of Alienware proprietary technology, NEC could be sitting on a goldmine if it markets the CRVD-42DWX+ just right.

Of course, the math for 3d perspective rendering only works for a flat display, and a curved display would result in an incorrect image.

You could do a different projective transform for each vertical line of the display and get a correct image, if the engine knew the curvature of the screens. It would be easiest if the curve was a circular arc and it was assumed that the head is at the circle's center. You would need to know what portion of a circle the monitor represented (a 60 degree arc would have avery different set of transforms than a 90 degree arc)

It would probably still be too slow on most hardware.

In short, I think I'll stick to flat displays for now, and this monitor is not really well-suited for serious gamers.

How would it work as a touch screen? I think the touch screen will be the UI of choice in the not too distant future.

I disagree - for desktop monitors at least, touchscreen has a number of undesirable attributes. For one, the optimal distance for visibility is greater than the optimal distance for touch. This results in the display being either too close for viewing or too far for touching.

Then there is the problem of smudged, dirty displays.

I think touchscreen use will certainly grow in some segments (e.g., handheld devices, kiosks), but I think the mouse will continue to be used on the desktop until a new technology is widely-used, e.g., sensors that can track eye movement and move focus based on that.

"sensors that can track eye movement and move focus based on that."
Would hand movements do?...

No I just found about him a couple days back.

Really amazing what he came up with, it's like being Tom Cruise on Minority Report when he fools around with the interactive display.
