As display resolutions get bigger, we begin to approach the fundamental limit of human vision. This requires a shift in the way we record and display imagery Some quick calculations.. Using Sun's definition of human resolution (28 arc-seconds), we determine that a human can discern objects of 0.135 mm at one meter. Note that this high-resolution field only applies to the centre 2 degrees of vision. Assume we have an 8K TV that's 55" diagonal, so each pixel is about 0.149 mm wide. So to actually exploit the resolution of that TV, the average human would need to sit about 1.1 metres in front of it. But at that distance, the TV is taking up over 100 degrees of the field of vision, and only a small part of that field is viewed in full resolution. So part of the shift to higher resolutions will require increasing the angle of view of the source imagery. As a side note, sitting one metre in front of a TV would bit a bit awkward, so this level of resolution is probably better realized using something along the lines of a head-mounted-display.

I am working on an archiving project and I wanted to produce a 4320p video that would push the envelope for video card and display technologies. I was day dreaming about my video appearing at the olympics...

Bert, Stereoscopic vision works by comparing the 'disparity' of corresponding image elements in left and right views. There is no question that sending all the pixels will produce a palpable 3d experience. It is also possible that the half images could tolerate some form of lossy compression, but it would take an enormous amount of psychophysical research to establish the parameters. As you suggest, the makers want to sell these RIGHT NOW.

Re 55" TV for 8K hi def: Estimates for optimal viewing distance for 1080p are all over the map. Using Sun Microsystems's estimates for human visual acuity (twice as high as most sources) you must view a 55" TV at no more than 13' to fully exploit the resolution of a 1080p image. Since the 8k tv has a linear pixel density 4X that of 1080p, you would have to sit roughly 4 times closer. Other acuity estimates put you even closer. Keep plenty of aspirin on hand. See wikipedia article on optimal tv viewing distance.

I don' t know. But you're right. It would be ineresting to find out what sort of chips are enabling this. We will be on it.

From all these discussions i feel that 3D tv is not attracting most of the viewers at this time.Even though this is the prime area of R&D ,till a attractive solution is not found. So a real 3D projection in space will attract every one, provided affordable.

3-D is all about content. NBC being idiots and exclusively broadcasting US athletes' activities is not a reflection of the technology and is something I am glad I did not have to watch. Even in 1-D NBC's Olympic coverage smells of arrogance and feeds American xenophobia and ignorance. I watched it for hours each day in another country...how refreshing it was, and I don't spectate sports.

@Junko: Does Panasonic have UHDTV resolution projection system? It will be interesting to know what kind of DLP/DMD projection chip they use for this. Panasonic's high lumen projection looks quite impressive.

Well put. And I think many of us do agree that the Ultra HDTV won't make sense unless you have a HUGE wall size screen. Looking back on how long it took for HDTV to get off the ground, I see UHDTV something we may see in one or two decades from now. Still, I actually think what UHDTV can bring to us in terms of realism is something really remarkable. Sure, we won't be able to afford it any time soon; but it does amaze me.

What prompted you to work on UHDTV video, may I ask? Was this a part of your work project?
