Here is a good read on perceived resolutions for Screen Size / Seating Distance - http://carltonbale.com/1080p-does-matter/
Hendrik:
Those charts are all nice and everything, but I can sit on my couch and when I really concentrate, I can make out the pixel grid on my 1080p TV. Of course that vanishes if there is any kind of motion, but the fact that I can see individual pixels is a clear indicator that the resolution is not high enough yet.
Of course 4K is not ready for buying yet, but that's another matter entirely.

I think the increase in resolution is largely a marketing ploy. I don't know if it'll work, though I strongly suspect that it will "work" in basically the same way 3D "worked": All TVs will eventually be 4k, but it won't lead to a massive avalanche of sales as people upgrade existing, working sets. That's a failure as far as the TV manufacturers are concerned, however...
The UHD standard is not just about the dubious higher resolution, and I think far beyond the resolution (which is easy to explain to lay people) this is what most people will "see" when they claim to see the difference between 1080p and 2160p. There are two other, much more important, changes coming with UHD:
1. Die, interlacing, die. I don't think much needs to be said here, but there is no more i. Yay!
2. Rec 2020 has a dramatically increased color space (~76% of CIE 1931 as opposed to ~36%). This will, in my opinion, lead to the biggest perceptual change in "quality" with 4k native content. That's what you'll see. Of course, this will also mean that some lower-end TVs will do terrible things to older 480/720/1080 content in the older color space. So, it is a double-edge sword.
If it gets a bad rep, leading to failure, it will be that last point. High end TVs will have nice conversion engines. Low end TVs like the Sceptre's and crap sold at the local Walmart or Costco? We'll see, but I'm skeptical. They could end up shooting themselves in the foot with their cheap sets, which will give the whole thing a stink.

I could go into detail about why that chart is wrong, but let's just say that flawed assumptions were used when creating the chart (the idea that you should be able to discern individual pixels) data from more recent studies was ignored, and that viewing distances should be at least twice what that chart indicates.

I agree that the chart is a dramatic oversimplification.
That said, there is still very little or no benefit to 4K TVs with current typical display size and seating arrangements. I also think it is unlikely that we'll see a further dramatic increase in typical display sizes, as you're hitting the limits of what can comfortably fit in rooms. And, people just don't want to sit that close.
Color gamut matters. 2160p might look better, but the improvement is very marginal until you get to "theater" sized displays. Certainly not something that the unwashed masses will throw away their working TVs to get.
And that has been the goal of all of the "waves" of "next big things" in display technology (4K the latest in a long string). Reclaim the "glory days" of the first HD upgrade cycle. It isn't likely to come again anytime soon (or, at least, not from any of this stuff).
