Sharp Announces 8K Consumer TVs Now That We All Have 4K (theverge.com) 285

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.

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 th

        I recently got a 4k TV and while the best material I have is 1080p (above a certain size it's hard not to get a 4k TV anymore at least in the UK) what I really notice is that the interface for all the catchup and Pelx is now super sharp. Way better than a 1080p screen which I also have. So while I don't have an 4k content to play back having used a 4k TV for a couple of months now there is no way I would buy a none 4k TV in the future.

    • by AmiMoJo ( 196126 ) on Saturday September 02, 2017 @05:55AM (#55127991) Homepage Journal

      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.

          Indeed. Broadcast video quality in Japan is vastly superior to anything I've seen in the US or UK. They decided to have a small number of high quality channels instead of a large number of shit quality ones. In Tokyo you can get about six channels over the air.

        The lenses that collect the video also have limits and, no surprise, they are similar in spatial frequency resolution to the eye. So at some point, and I can't swear it's at 8K excatly, you just aren't collecting new information.

        Thus the anti-aliasing also gets fixed at the collection step as well.

        I would assume it has more to do with the Bayer Filter [wikipedia.org] and demosaicing in particular, than Nyquist, however the point is well taken. At least as far as sampling is concerned. For example, you wouldn't shoot with the intent of displaying on a 1MP display with a 1MP sensor.

        While technically the post is "interesting", it is only so because of how poorly informed the author is.

        Without any information regarding viewing angles, no conclusion can be made regarding whether the eye can see individual pixels or not. If it cannot, then it cannot. Aliasing is unrelated to this and is handled upstream of the display. Furthermore, the eye isn't "quite good" at "spotting" aliasing, aliasing appears as false detail, no different than any other detail to the eye.

        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

    Seriously. Look around. If you're looking at large TVs, or TVs with ultra high definition, what do you see? "Smart" TVs. Meaning: TVs with embedded computers. Meaning: security risks. Meaning: do the manufacturers keep these things patched and up to date when security problems are found?

    So forget this "smart" TV thing. I want a bog standard, every day, dumb TV, with no smarts built in. If I need those smarts, I'll get an Apple TV, or a Roku, or a Chromecast, or something. At least that way, if I have to ditch the device because it isn't being updated and has a known security problem, I'm only out a couple of hundred bucks - instead of several thousand for some of those high end disasters waiting to happen.

    To a comical degree actual display quality is limited by compression that dominate most Internet/Satellite/Cable/OTA distribution channels in the name of saving money and cramming more stations into limited bandwidth.

    So far marketeers seem to be getting away with suckering people into giving a shit about meaningless things like display resolution when those who care about quality are best served spending their time demanding content distribution providers quit turning content compression dial up to 11. They will always seek to turn that knob as far as they can possibly get away with.

    The reality for consumers:

    2k is overkill.
    4k is worthless.
    8k is comically worthless.

    HDR and more efficient codecs (HVEC) are what will actually drive perceptible improvements that actually matter.
