This is good stuff. I would like a 22" monitor with this resolution.

24" for me. And x2400 for vertical resolution.

Anton, that detail seems to be missing in the news post, can you confirm this is a 10bit display/panel, as in it can directly display generic 10bit x264 4K [well 3840*2160 at least:] encodes (with a 10bit patched player like vlc etc) without conversion to the average 8bit display in use today ?

You DONT KNOW what youre asking
10bit encoding scheme has nothing to do with 30bit RGB So it would be wise to inform yourself before asking such intellectual geek questions.

HINT: Every display in use, even 6bit TN panels, displays 10bit x264 encode natively as long as you marked stream as 10bit and you have proper decoder for it. That 6bit do excessive dithering even on old MPEG2 that's also visible but that's part of technological migration.

indeed OmegaHuman, when i said "without conversion" i should have said without dithering to be clearer perhaps, oh well, OmegaHuman one upped me so heres an up vote

oc you also recall most displays are 8bit per colour not 10bit per colour today and that does have a visible effect too...

Seem that all wanna be giikz want 24" display with 4xWUXGA resolution (5120x2400). Well dream on for at least next five years and this probably wont be a standard as this "4K", "OctoHD" is long in announcement (earliest 2010) and its only now, fall 2012 that we see real products.

Its interesting how this displays will be highly priced as tech must migrate from polySI and aSi. So real availability of sub 1000USD crap we should expect in Q2 2016 or what? (ofc, assuming that USD stays at today value)

The best market assumption are pro-users with a wastful of government and small peoples money

Demand for ultra-high-definition 4K displays is forecast to grow for numerous business and professional applications, including creating and editing graphics and video, financial-related operations requiring intensive use of graphs and small text, and CAD services for displaying detailed drawings

Or to say it this news aint wort a schaiße until it will be affordable to consumers. And it seem thy intend to millk of a pro users and let the rest drooling for it for next few years.

And marketing nonsense to sound very wise
The PN-K321 is Sharp's latest 32” ultra-high-definition (3840*2160) display and features smaller transistors (TFTs) in the LCD panel compared to conventional displays, thereby increasing the amount of transmitted light per pixel.

Woooow, ofc, that feature size of transistors should reduce if we have 4 TIMES MORE transistors on same area. But in fact light outpšut has nothing to do with it. They theoretically can output 4 TIMES more light if they're the same as transistors used in FullHD but that would also mean at least QUADRUPLE power consumption not even counting drivers behind screen
