8K TVs Are Coming, But Don't Buy the Hype (engadget.com)
If the 8,294,400 pixels of resolution on an Ultra High Definition television just don't seem to convey enough detail, fear not: The electronics industry has heard your cry. From a report: Even as UHD TVs, often called 4K TVs for their nearly 4,000 pixels of horizontal resolution, approach half of display shipments in the U.S., set manufacturers have been stepping up their demos of 8K sets that, with their 7680-by-4320 resolution, pack in a full 33,177,600 pixels. And Sharp is now expanding its distribution of one such set, the 70-inch LV-70X500E. Following its October debut in China and subsequent arrivals in Japan and Taiwan, this 8K display will go on sale across Europe at the end of April for about $13,800 at current exchange rates. That, apparently, is supposed to be a reasonable price for a set that supports a video format that offers next to nothing to watch, that can't be streamed on most broadband connections or fit onto Blu-ray discs and which can't even be properly appreciated unless you get a set too big to fit in many living rooms.
[...] The highlights reel playing on a demo unit of Sharp's 8K set required 300 megabits per second of bandwidth to stream, said Adrian Wysocki, group product manager at UMC, the Sharp-owned firm that builds TVs in Poland for the company. He suggested in a conversation Friday that more efficient formats could cut that to 100 Mbps. Only 23.2% of U.S. fixed-broadband connections hit that speed at the end of 2016, according to to the Federal Communications Commission's latest report on internet access services.

Sure it's going to be a while before you see much 8k VIDEO content...
But what the naysayers are ignore is how awesome these will be for images.
Also a nice side effect of putting on 8K displays, is it drives the cots of 4k displays even cheaper in the meantime.

Maybe its because you're too busy telling kids to get off your lawn instead of watching TV.
Even if you're one of the lucky few who can really get 100 mbs, how many customers can your ISP support all streaming 100 mbs at the same time before your ISP's peering points get saturated and you get throttled in some manner, or need a higher priced option in order not to be throttled ? Of course, that would only happen after you've already spent the $13k.

Keep it. I have a 4K monitor for gaming, but there are very few videos exist at 4K that make me go wow. There are a few, mostly nature documentaries that will do it. I have yet to see a 4K movie worth the extra cost.

This is just the beginning.. Watch for 128K

At least hold off until you can buy Monster Ethernet cables so you get the bandwidth you need.

True, it is all digital. And the cheap 3$ HDMI cable from Alibaba might suffice for the "High" def content. But to handle the 8K steam you need a gold plated, silver core 10 gauge wire HDMI cable from Monster. The zeros would be a perfect circles and the ones would be perfectly straight and vertical no matter how twisty your cable is. You definitely need it for 8k.

If you're sitting close enough to see the pixels, you are 'watching the equipment' not the show. Like an 'audiophile' listens to the stereo, not the music.
4k screens are for monitors and VR displays, 8k will be the same. I'm just glad stupid people will cover the R&D costs of my future monitors.

When 4k came out at five digit prices how much content was available for that? Obviously no one is going to run out to spend $13,000 on a 70" 8k screen. This is for the future, when 100mbit broadband is more common. Remember the cheapest, smallest 4K screens from budget brands like Westinghouse and Hisense were a whopping $4,000-$5,000 in 2013. Those same tvs sell for $300 today. http://money.cnn.com/2013/01/1...

Pales in comparison to Frank's 2000" TV. I heard he got the last one in stock.

No, I will not work for your startup
Rich people, really. What do you think I'm going to do when that $175k Congressional salary starts rolling in? Buy a $1,500 bespoke suit at my local tailor, of course. There's no way I need a $175k salary, so it may as well go into the local poverty-stricken district of my city where some entrepreneur has attracted wealthy clients to create local jobs.
Of course I'm going to eliminate my mortgage and car loan, too. That'll take uh. Two months. I'll also have a nicer yard, seeing as so many people in my neighborhood are desperate for jobs and are willing to clean up the trash and do the gardening for pretty cheap. Even at $15/hr, that's only $150/week for a ten-hour weekly maintenance schedule. I'd like to rebuild my rear deck with some composite but maybe I'll just pay somebody else to strip it down and redo that for me, too; along with doing some electrical work and finally installing that 40-amp ChargePoint I've been meaning to get.
I'm still not buying a $5,000 TV; screw that. 4K UHD OLED TVs will be under $1,000 by the time I'm ready to buy.
What? You didn't think I'd already planned for how to deal with this unnecessarily-large compensation package? I plan for everything.

8K broadcast standards use Rec 2020, which has a much wider gamut and can therefor show colors that most TVs these days can't. Rec 2020 is even wider than the DCI-P3 that many high-end monitors benchmark against these days.
Rec 2020 also defines a larger bit depth: 10 or 12 bits per component rather than 8. This is partly to support the wider gamut, but it'll also help everything else by allowing much better gradients.
Even if you don't have an 8K TV, ones that use HDR10 and Dolby Vision will benefit: both of these standards use the Rec 2020 gamut. So... bring on the 8K revolution. I want better browns.
Very hard? I would almost say impossible. I've actually been pricing UHD tv's for the greater part of a year now. One of the requirements is I want a dumb one. But there are none to be had.
My current tv is a 6 year old visio. It started life as a smart tv then gradually all the apps stopped working and where never updated. I said "fuck it" and bought a ruko.

Heck, it'd make for an awesome computer screen too. Might be a bit much for most current gaming hardware to drive, but by the time it becomes mainstream I doubt that'll be a problem. In the meantime, it means smoother fonts and crisper images. I'm right at the cusp of upgrading to 4k - they're finally making affordable 40" 4k TVs (about the largest screen I'd want at arm's length), I'm just waiting for the improvements to slow enough that I don't get buyer's remorse right away as next month's models significantly improves quality at the same price point.
But even a "small" 40" screen has visible pixels at arm's length, another doubling in dpi should push detail down below the obvious perceptual threshold.
And of course if you're getting a bigger screen, which are increasingly popular, then you'll notice that 8k improvement even at larger distances.
Heck, even video will improve - you don't need higher resolution *content* to appreciate a higher resolution *screen* - all you need is a decent upscaling algorithm. I mean sure, even excellent upscaling isn't going to make a DVD look as good as Blue-Ray, but it can make it look a lot better than it did on a CRT.
Of course, even 4k is more detail than you really need for a movie unless you have a rather obscenely large TV, or like sitting quite close to it - but hey, video buffs need love too! And hey, it's not even like audio enthusiasts don't get anything for their money with those oxygen-free gold-plated audio cables. Sure, the sound is physically indistinguishable, but the placebo effect improves the subjective experience anyway.

Yep. And far be it from me to mock those wealthy cutting-edge enthusiasts for creating an initial market for things I'd like to someday have. 8k might not be an earth-shattering improvement for watching movies from the couch, but ~200dpi on a 46 inch computer monitor still leaves plenty of room for improvement.

I have a 1080 tv and a 2160 set, the 2160 looks a lot better but it's also 10 years newer. These anecdotes are useless.
It used to be true that people would purchase a television and keep it until it broke down 10, 15, 20 years later - then they'd buy another one.
Now these companies are trying to get us to buy new TVs as often as we buy new phones.
I've got a 1080P LG television we bought 2012-ish. I don't care if the new TVs are somehow "better" than the one I've got - mine works fine and the display looks good. I'm likely keeping it for as long as it continues to function.
Now, kindly remove yourself from my lawn.

Super cheapies. Don't let the bad reviews scare you. I just paid $300 for a 55 sceptre dumb 4k TV, Walmart online only.
It's OK, the name brands aren't better at the economy end and are all 'smart' only, which makes them worse.

No doubt, if you press your nose to the screen you can see the difference. 8K is really a theater projector standard: in order to see the difference between 4K and 8K, the screen will more than fill your field of color vision. If you're sitting closer than most people find comfortable, such as the front row of a movie theater, or 5 feet from a screen with a diagonal larger than that, then you'll see the difference.
At a common viewing distance for a given screen size, you can't see the difference, but that's not all use cases.
Socialism: a lie told by totalitarians and believed by fools.
From your wikipedia citation:
the human eye should have a resolving power of 20 arcsecs in theory, though normally only 60 arcsecs.
Stated better, the human eye is diffraction limited at 20 arc seconds, but other factors limit the typical resolving power of thew human eye to 1 arc minute.
Some people have exceptionally good vision and can do better than 1 arc minute. The GP claim of 31.5 arc seconds is silly in its exaggerated precision.

I'm going to wait for the 16K screens to come out. I calculate that will finally be enough pixels to make "The Emoji Movie" watchable.
I don't care if it's 90,000 hectares. That lake was not my doing.
There's never going to be TVs big enough *and* cheap enough for the home to actually make good use of 4k, and 8k TV will never be useful in the home, period. You'll need way too big of a TV, and that'll never happen.
