Now one can compare photography techniques with various cameras and see the human eye can readily discern the absence of clarity on smaller cameras vs much larger sensor based cameras. Simply discussing resolution totally omits the quality of the source, and that is far more important when discussing what your eyes can perceive.

4K TV's/content still shows a lack of clarity that your eye perceives at various distances. Until I see TV content that resembles what I see naturally we are not at the ultimate presentation perspective yet.
Why are you trying to refute scientific fact?

How can so many people be so wrong about 4K? I think it boils down to two false assumptions. The first is that vision is limited to 20/20 and second is that the digital media can capture all of the resolution at the resolution of the imager. Both of these are false. Here is a quote from an expert on human vision. August Colenbrander, M.D. (Smith-Kettlewell Eye research Institute and California Pacific Medical Center) “…emphasizes that, contrary to popular belief, 20/20 is not actually normal or average, let alone perfect, acuity. Snellen, he says, established it is a reference standard. Normal acuity in healthy adults is one or two lines better. Average acuity in a population sample does not drop to the 20/20 level until age 60 or 70. This explains the existence of the two lines smaller than 20/20: 20/15 and 20/10.”
I know this is only a HD vs UHD article, it just illustrates that there are actual discussions on visual acuity rather then home theater people utilizing some chart as gospel. Always felt those were more for just selling larger displays or screens than needed.

8K TVs Will Be In 56 Million Homes Worldwide By 2025, Says Strategy Analytics

MILTON KEYNES, England--(BUSINESS WIRE)--Apr 2, 2019--8K TVs are set to achieve modest success over the next few years, according to the latest research from Strategy Analytics’Connected Home Devicesservice. The report will be published to coincide with this month’sNAB Showin Las Vegas, where 8K, which offers four times the resolution of today’s 4K standards, will be one of the dominant themes. Strategy Analytics’ consumer technology adoption models predict that 56 million homes worldwide will own an 8K TV by the end of 2025. The US will be the most successful market, with 8% of households owning an 8K TV by this time. 8K TVs have only been introduced in recent months, and the research finds that global sales in 2019 will reach 0.5 million units. Compared to the US, where super-large displays have long been accepted, 8K TV will struggle in most other regions. The report concludes that 8K TV will be good for TV vendors, but less meaningful for the content industry.

I believe Lee because the economy is doing quite good all across.
Two things inspire people; 8K and 5G.
Everything else is not important...oil, guns, drugs, gold, batteries, turntables.

Scanning things in 8K (which has indeed been around for years just as 4K has been, Japanese company Imagica's large format scanners have long been at the forefront of this) is one thing, actually mastering them out to 8K is something else. Wasn't one of those same remastered Ron Fricke epics scanned at 8K but actually finished in 2K? Heh. And if we're watching conventional 24p shot with a 180-degree shutter then the amount of pixels means little as to temporal/motion resolution, you're still going to lose a ton of motion resolution any time something moves.

24fps motion judder has been significantly exacerbated in the 4K HDR era (due to how much more information is being resolved with that higher brightness and contrast) and just bumping up the spatial resolution isn't going to help with that, people noted how bad the judder was on the Sony 8K set at CES last year. When it comes to real world content 8K is going to run into the exact same issues as 4K, perhaps even more so. If it's motion resolution people want then more pixels aren't going to cut it on their own.

And if you see any 8K vs. 4K TV demos at industry shows in which there is any significant actor motion or camera panning motion and the 8K60p footage looks superior to the 4K60p, then the TV manufacturers are not including the best processing they have in their 4K TVs.

So, in terms of providing the public with greater picture detail, what should the industry be concentrating its efforts on?....with supporting hardware for increases in spatial or temporal resolution?…..unless one wants to view panoramic landscapes with locked off cameras, talking head content....

8K adoption will only go forward if the industry forces 8K upon the masses, as they did with 4K and the removal of common-sized HDTVs from the market to drive sales of 4K TVs due to TV replacement. Also, super-large displays are not the norm in Murica and haven't really been a thing since the DLP days, when they had car-sized options at the high-end. I live in one of the wealthiest areas in the country and even the millionaires rarely have something larger than 60-inches in their home and if they do, it's usually a projection screen. That might change with mLED video walls, but it's too early to tell what might happen with that particular hardware niche.

I’d welcome 8K only because

1. I have no choice in buying non-4K TV in the future
2. I still will benefit 8K for my projection

I think it's important to differentiate between the adoption of 8K TVs and the availability of 8K content. The model will follow the 4K TV model only with even less content to be available.

Here we are 5 years after the introduction of 4K TVs and I firmly believe that there is less than 5% of all available content in 4K. Less than 25% of all USA Households have a 4K TV. The content providers aren't falling all over themselves to rush out 4K content. That is obvious.

TV manufacturers need to sell "the next big thing" which provides them with a healthy profit per display sold. That no longer exists (for the most part) on 4K TVs. So they introduce 8K TVs . . . Big and Expensive.

I am sitting on the fence as to whether I feel we will see 8K content (outside of Japan and maybe S. Korea) in the next 20 years. I am leaning into the "NO" side of the fence BTW. Yet in 20 years, we may see 8K TVs in well over 50% of all USA Households.

Once the TV manufacturers began to emphasize that HD content looks better on a 4K TV . . . "the end is nigh"
