Sharp Announces 8K Consumer TVs Now That We All Have 4K (theverge.com)

Thuy Ong reports via The Verge: Now that you've upgraded to a shiny new 4K TV, Sharp has revealed its latest screen to stoke your fear of missing out: a 70-inch Aquos 8K TV. That 8K (7,680 x 4,320) resolution is 16 times that of your old Full HD (1920 x 1080) TV. Sharp calls it "ultimate reality, with ultra-fine details even the naked eye cannot capture," which doesn't seem like a very good selling point. Keep in mind that having a screen with more pixels doesn't buy you much after a certain point, because those pixels are invisible from a distance -- while an 8K panel would be beneficial as a monitor, where you're sitting close, it won't buy you much when leaning back on the couch watching TV. HDR, however, is something else entirely, and fortunately, Sharp's new 8K set is compatible with Dolby Vision HDR and BDA-HDR (for Blu-ray players). The lack of available 8K HDR content is also a problem. But there is some content floating around. The TV will be rolling out to China and Japan later this year, and then Taiwan in February 2018. Sharp is repurposing its 70-inch 8K TV as an 8K monitor (model LV-70X500E) for Europe, which will be on sale in March. There is no news about a U.S. release.

      I was watching a DVD the other day and noticing the pockmarks on the face of one of the characters. The jump from VHS to DVD quality was very noticeable. Anything beyond that and I stop caring - occasionally there are scenes when it makes a difference, but they're rare. 4K is nice for a monitor, because it makes text rendering a lot crisper (barely any antialiasing needed), but for video I don't care. 8K is probably more pixels than I can resolve unless the display is positioned such that I don't fit the entire thing in my field of vision at once.

      8k resolution is close to IMAX for detail. Not quite as good as 70mm film, but close.

      You also have to remember that even if your eyes can't see individual pixels at that resolution (a good thing), what matters is the Nyquist frequency which is half the sampling frequency. That's why CDs sample at 44.1kHz, even though the human ear can't hear much about 20kHz.

      Basically 8k reduces aliasing, which is something that the eye is quite good at spotting and makes the image look artificial. That's why most of the 4k demos you see are careful to select images that avoid aliasing.

      8k isn't just resolution. When they start broadcasting in Japan for the 2020 Olympics, it will be 60Hz native format, and with a colour gamut beyond what current TVs can display.

      8k isn't just a resolution bump like 4k was, where they mostly used the same equipment and some upgraded but fundamentally the same cameras as HD/2k. For example, manual focus is impossible with 8k. Until recently only extremely specialist, power hungry hardware was able to process an 8k video stream and save it to storage fast enough. NHK, the Japanese national broadcaster, has been working on it since the 90s and skipped over 4k to concentrate on it. It's not just incremental, it's a genuine attempt to make video almost indistinguishable from reality.

      But PPI is an irrelevant metric when you don't count viewing distance. Computers and smartphones need high PPI because they tend to be used within a foot or two of your eyes. TVs tend to sit 10-20 feet away from you. That 70" screen at 68 PPI is probably more pixels than you can possibly see at the viewing distance you're actually watching it from.

      You can't actually see the difference between even HD and 4K in the vast majority of home TV setups. The average setup is a 40-50" TV sitting 10-15 feet away from the viewer, at those distances and that size screen, you just can't see it. (I won't even discuss the poor lighting, glare, and viewing angles of your average home TV setup) Now if you actually have a more theatrical type setup where you have a screen that fills most of your field of view, that's a completely different matter, but that's actually somewhat rare in home setups, in those cases the difference from HD to 4K is noticeable (though not as major as you might think) but even there you're unlikely to notice a difference from 4K to 8K.

      Now there is one place that 4K really does shine though, and that's computer monitors, a good 4K monitor is great, but that's because you sit so close to it in that application.

      Yeah, but you can eliminate that from the equation because 20/20 vision = one arch-minute (1/60th of a degree) of resolution. So if the TV covers 30 degrees field of vision (FOV), you can see 30*60 = 1800 pixels of resolution (with a perfectly curved screen where you don't have aliasing effects, 3600 if you do). Now most young people have better than 20/20 vision because that's just the threshold we've set for normal, doesn't need correction vision and if you're really enjoying your widescreen you might be pushing 50 degrees though that's uncomfortably close for most. But even if you have a 50 degree FOV and 20/16 vision you'll at most see 50*60*20/16 = 3750 pixels, which is like front row at the cinema with your average teen eyesight.
