Toshiba announced that they are about to start shipping their 2160p HDTVs. Will this be the next big thing in computer monitors? Most monitors are about 100dpi. So a 2160p monitor at 100dpi would be about 44 inches diag. I think I'll need a bigger desk.:D

Here is a link to the announcement at TV snob.http://www.tvsnob.com/archives/028862.php
 
For PC displays, this will be the next big thing after 30" 2560x1600 displays, but as for TV's there is ZERO benefit with all source media still at 1920x1200.

Well, the benefit is that both 720p and 1080p can be played pixel perfect. And for other uses than TV it could be quite nice.

For a computer though one can only hope it'd be 16:10.
 
I think that Full HD 3D is going to be such a gimmick. I can't see it lasting very long.
 
Shrink that down to 32", give it displayport, take out the unnecessary blurayplayer and video recorder, price it under 1k and I'll consider buying one for PC use.
 
2160p is 3840x2160, or four times the pixels of a 1920x1080 monitor. Most 1920x1080 monitors (as opposed to TVs) at this time seem to be 23", so doubling the diagonal would make it 46".

A 46" 3840x2160 monitor would indeed be great, but cable limitations are a problem:

3840x2160 = 8,294,400 pixels
8,294,400 x 60Hz = 497,664,000 pixels per second
497,664,000 x 24 color bits per pixel = 11,943,936,000 bits per second, or 11.9 Gb/sec

1680x1050@60Hz = 2.54 Gb/sec
1920x1200@60Hz = 3.32 Gb/sec
Single-link DVI maximum speed: 3.96 Gb/sec
1680x1050@120Hz = 5.08 Gb/sec
DisplayPort 2 pairs maximum speed = 5.40 Gb/sec
2560x1600@60Hz = 5.90 Gb/sec
Dual-link DVI maximum speed = 7.92 Gb/sec
HDMI v1.3/1.4 maximum speed = 10.20 Gb/sec
DisplayPort 4 pairs maximum speed = 10.80 Gb/sec
3840x2160@60Hz = 11.9Gb/sec
HDMI Type B maximum speed = 20.40 Gb/sec

Uh oh... 3840x2160 at 60Hz exceeds both HDMI and Displayport bandwidth. 2160p TVs get by this because HDMI 1.4 allows 2160p at up to 30Hz. For 2160p monitors, HDMI Type B is the only hope, but has yet to be seen on any consumer device.

Would it be possible for the 2160p monitor to have two separate cables that drive the single display? A Radeon card with Eyefinity can support up to 8000x8000 pixels spread multiple display outputs from a single card. Theoretically, wouldn't it be possible for, say a Radeon 5870 Eyefinity to treat a 3840x2160 monitor as 4 separate 1920x1080 displays and drive them through Eyefinity to be seen as one single 3840x2160 monitor?

That's sort of how the IBM T221 works, but instead of dividing the physical display up into separate monitors it takes separate full screen signals from up to 4 single-link DVI inputs. More inputs = higher framerate.

I think that he is going after the fact that it only mentioned that it upscales 1080p to 2160p. There is the real possibility that this TV will only be able to accept input resolutions up to 1080p.

The highest video format is 1080p.
2160p does not exist. 2160 is the monitor vertical resolution.
All monitors with 1920x1080 and higher resolution that are able to support 1080p signal are 1080p or Full HD monitors.

DP 1.2 is 5.4Gbps per lane, or 21.6Gbps x4.
 
...and here I am with an ancient Dell 2007WFP (with the S-IPS panel) at 1650x1050. :(

I really need to get a new monitor or three.

But is it available? They announced it in January 2009. I tried to find out if the ATi 5800 cards have 1.2, but failed to determine that one way or the other. Monoprice just says it has Displayport cables without mentioning the version, though it seems implied that they aren't 1.2 (and what they have is backordered to October 7). The only monitor I can be sure of that has DP 1.2 is the 24" Apple Cinema Display, since Apple's mini-Displayport has been defined as being included in DP 1.2 spec. At this point I'd have to put DP 1.2 in the same category as HDMI Type B.
 
One immediate benefit of 2160p is that 2160p is an integer multiple of 1080p and 720p.

Also, with ATi's eyeinfinity tech, driving 2160p through 4 input shouldn't be an issue.

The worst case scenario would be that you use the other two DP inputs on the 5870 six you're bound to have(because we're already at four inputs) and scrape by there right?

Though that is a lot of cables for just one monitor.

Why the heck would anyone want to watch their brand new 46" 2160p monitor @ 30hz? This monitor either needs dual HDMI cables or a new cable specification!

That's where the TV world is different from the monitor world. 24Hz or 30Hz is perfectly acceptable for film and TV. Did you know that the 1080p that Blu-Ray discs put out is limited to 24Hz?
