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.

The problem with those Fresnel-lens based systems, is that the observer has to be positioned exactly right in order for the 3d effect to work.

Depending on the DLP system used in this monitor, it may already be 3D-capable using shutter glasses.

Samsung's latest DLP TV sets are all 3D-ready, they include a sync port for that very purpose.

I'd love to try one out, I'm curious as to how noticeable the flicker will be (

You are partially right about the positioning.

If you have multiple displays such as 3 or so - then to achieve the overlap - yes you'd need to be a specific distance away to get it and you wouldn't want to be that far off. If you are, you might have some alignment problems.

As far as 3d effect - not so much. I use one every day (a single display one). Weather I am 1 foot from the lens (not the screen - the lens itself is 10.5 inches from the screen) or sitting 2 1/2 feet from the lens, the 3d effect is present in both situations.

However, if I DO sit further back, the 3d effect increases somewhat, but there does begin to be some slight distortion around the edges if I push it back too far.

The effect is VERY nice when I'm sitting real close to the lens for FPS games, and also equally impressive when I'm sitting much further back for simming. I even have a Track IR for head tracking and turning my head in no way messes up the image or 3d effect.

The shutter glasses sound interesting, but would be a problem especially if you wear glasses to begin with.
I am curious if the effect is anything like you'd see going to one of the old school theme-park style 3d cinemas (think MGM or disney world) - it was pretty spiffy but it tends to hurt your eyes a bit. I'd also be worried about them generating a headache from said flicker with the tv based displays.

To the poster that mentioned CRT's, I never once said they aren't moving out of the limelight. Regardless, you can not dispute that CRT's are superior for handling multiple resolutions without distortion. Fresnels can be used just fine on a LCD screen, provided you build a stand for the lens that can support itself. A CRT affords you more flexibility due to their weight, you can just velcro on a housing. I've seen some videos of 3 LCD fresnel setups - they look very good.

Depth-fused 3D seems to me to be a more tractible means of getting 3D -- no fresnel lenses, no shutter glases, can use much of the existing LCD manufacturing processes ...

Interesting, I remember reading about these a while back and I'm curious how they have progressed. Have you ever seen one?

The most important thing to note about Depth Fused Displays is they are run by a RGBZ signal - i.e. the Z signal controls the depth of each pixel/image. This means software would have to be customized to supply this information - OR - hardware such as your graphics accelerator would have to interpret from the geometry data the position of each pixel in space and supply this information via the Z signal.

Since our graphics accelerators already handle geometry data, I'd simply require a revision of hardware spec to supply this additional information. Either way, I don't think someone could simply hook up a DFD display to their existing PC and play.

Fresnels require no hardware or software modifications at all, you just hook them up and you're ready to go.

How does it handle depth of field? With a collimator such as a Fresnel, if you sit 2 feet from your monitor screen, your eyes do not focus on an object 2 feet away, but instead focus on something much farther back.

If you removed the fresnel you'd focus 2 feet away. This is one of the primary reasons why fresnels work so well - they trick the mind into thinking the image is much further away, rather infinitely away versus right in front of you. I'm curious how much depth they can create on a DFD.

Interesting technology regardless - as long as we move away from 2d images we're making progress :)
