Enter The 2160p HDTV

Dr. Eggman writes "The Consumer Electronics Show is kicking it in high gear as Westinghouse shows off its 2160p or "Quad" HDTV. While enthusiasts pine for new 1080p monitors Westinghouse has stated that the Quad HDTVs, like the 52" on display, "does not really target the consumer market, but high-end industrial applications.""

Yawn. This isn't even that monstrous (if the summary spec is correct). IBM T221 http://en.wikipedia.org/wiki/T221 [wikipedia.org] gives you 3840x2400 and can give you 48Hz off a single card (using both connectors).

Save your money for a UHDV living room. :)

Super Hi-Vision's main specifications:

        * Resolution: 7,680 × 4,320 pixels (16:9) (approximately 33 megapixels)
        * Frame rate: 60 frame/s.
        * Audio: 22.2 channels
                    o 9 -- above ear level
                    o 10 -- ear level
                    o 3 -- below ear level
                    o 2 -- low frequency effects
        * Bandwidth: 21 GHz frequency band
                    o 600 MHz, 500~6600 Mbit/s bandwidth

Hot damn!

NHK Super Hi-Vision [nhk.or.jp], of course.

Re:PS3 drivable?

[RicoX9]

Doubling the horizontal and vertical resolution gets you 4 times the number of pixels. Even if it could drive 4 1080p screens, that doesn't mean the timing logic is there to actually make a picture that makes sense. Most likely you would end up with a completely scrambled picture off a separate set of signals meant to drive 4 1080p screens.

Re:PS3 drivable?

No, 2160p is essentially four 1080p displays. Hence them calling it "Quad HDTV"

Re:What he really means to say

But even with that, DirecTV cripples their HD by dropping the 1920x1080 picture down to 1440x1080 so they can fit more content.

Check out the following WP quotes:

"HDV 1080i uses a pixel resolution of 1440×1080, but when displayed is scaled to an aspect ratio of 1920×1080 = (1440 × 1.33)×1080."

"HDCAM, introduced in 1997, is a HD version of Digital Betacam, using an 8-bit DCT compressed 3:1:1 recording, in 1080i-compatible downsampled resolution of 1440x1080, and adding 24p and 23.976 PsF modes."

"DVCPRO HD downsamples native 720p/1080i signals to a lower resolution. 720p is downsampled from 1280x720 to 960x720, and 1080i is downsampled from 1920x1080 to 1280x1080 for 59.94i and 1440x1080 for 50i."

Unless you have some extremely fancy gear, you're not doing more than 1440x1080 anyway. But hey, it's nice to think you're getting 1920x1080 footage.

Or display screens in a plant environment showing process flows, meter values and such. We have setups like this in the plant I work in and they use a wall of monitors (plasma screens running 1024x768, I think) to get all the information to a viewable state. The limiting factor appears to be just raw pixels - you can only make a font so small before it becomes unreadable, for example. With a higher resolution output device, the same information could be presnted in a smaller area, or use the same area to display even more information.

Re: Not just RED, also too low for Digital Cinema

[wisebabo]

The Westinghouse monitor is also, unfortunately, just a little too low for digital mastering/cinema applications. With the current paradigm being "master at 4K distribute at 2K" the monitor does not have the resolution for the mastering phase (4K = 4096x2160). That doesn't even begin to talk about the pixel bit depth, color space, gamma, etc. Also when the paradigm changes to "master at 4K distribute at 4K", then the film industry will really want 4K monitors for proofing.

Since it is very close to the required resolution perhaps the original manufacturer could be induced to increase the resolution slightly. Then perhaps Westinghouse could use closely spaced LED backlights that are individually driven so that the display could produce high dynamic range (HDR) images (very high contrast ratios). Add the appropriate color/gamma controls to match the digital cinema color space standard and NOW you've got a display!

Then again with all this I'm sure it will be NOT CHEAP.

Re:1080p Monitor? Why?

[Surt]

1920x1080 = 2073600
1600x1200 = 1920000

I think you may be wrong about which way the 10% goes.
