4k resolution coming

We can't say what's relevant and what's not from this point in time. I mean at present when I'm looking at my 1440 X 900 17" laptop display I can clearly distinguish the pixels.
In future with improving the ppi and resolution, that will be just a thing from the past and everyone, I bet, will admit that it is relevant...
You can't tell it simply becuase you haven't seen anything yet.
Well, the difference between 720p and 1080p in general is not big. From 0.92 MP to 2.07 MP.
8K is 33 MP, 4K is 8.3 MP.

I think the issue is content. We have 1080p because retail movies are available at that resolution. I don't know if they are willing to release 4K movies for consumers, if people just want to rent cheap movies for a buck. If they're going to sell 4K movies on Blu-ray media, then they should pad additional benefits for consumers.
HiDPI for portable displays may be more interesting given where Apple is heading.
EDIT: Apple's Retina MacBook Pro demo gave a glimpse of mixed 1080p video content with interactive UI for the remaining screen space, I think that direction looks more interesting -- as opposed to 1 big 4K video.

That's an absurd race in content creation. TV has already had to throw away anchorwomen and actresses over 40 without botox, 1080p is too much, On the other side, hw requirements for 4K are absurd, from storage through bandwidth to CPU time (on CGI).
It's just a desperate effort from the TV manufacturers to sell a new set next year. They should focus on OLED instead

Software optimisations. With the new resolutions and standards, new codecs will be released.
Yes, this I agree. But they need to solve the user acceptance issues first. e.g., What's the compelling end user values given the connected mobile lifestyle ? Should I invest in a new TV instead of other more interesting gadgets ? Is there a new breed of 4K apps ?
I'm not even convinced that Apple needs to release a TV. 8^P
... let alone a "generic" 4K TV.

Agreed.

Yeah, what do they intend to put these movies on? You get ~3 hours of 1080p on a 50GB Blu-ray IIRC, 4x the data means you need close to 200GB discs. Last I checked BDXL only goes to 128GB and I have yet to see one of those in the wild, not to mention Blu-ray adoption is still tiny, good luck getting anyone to switch.
For tetris? sure.

Current hardware required to drive a 4K display at reasonable refresh rates:
4x X-Fire/SLI Radeon 7970 or Geforce 680.
Approximate power: 1KW
Rate of power reduction at performance target: 50% every 18 months.
Minimum time until 4K is doable in 125W: ~5 years.

Also 4K as far as I can tell is the same as SACD, etc. A lot of pushing, not a lot of taking/buying.
I think they are considering the nextgen codecs. e.g., H.265.
It is said that 50Gb is enough for most movies but I have not probed deeper.

Isn't that counter-productive though, to increase compression rates and thus loss in order to achieve higher res? Or do new codecs have similar look/loss with higher compression? Not a big video guy, so I don't know, honestly.
From what I heard, yes.
This classic chart :
http://www.hdforindies.com/2006/12/when-does-1080p-make-difference.html
4k would, I estimate, place its ideal viewing distance on a 40" TV at 2.5 feet away. A US sized TV of 60" would need you to sit about 4 feet away. Normal sized TVs are not going to give a better viewing experience at hgher resolutions above 1080p for normal viewing. This makes it a useless feature to chase, at considerable cost. Ergo it's not going to happen. HD managed to start selling to the masses because HD offered some observable upgrade, although lots still can't tell the difference. Trying to sell someone a new 4k TV which doesn't look any better is going to be a hard sell. Only when you are supplying massive screens/projections, will 4k be important, and that'll be a tiny niche. LG's 4k set shown at CES this year was 84". That wants a viewing distance of something like 5 or 6 feet to make the most of 4k. Viewed from 10 feet away, 84" is amply served by a 1080p display. It'll be great for public viewing, like in a shop window where people can get close and check out the detail, but it's a useless consumer specification that won't result in significant numbers of displays, won't find support in consumer goods (have you tried filming and editing home movies at 1080p? Do you really want to blow that many more resources on filming and editing 4k movies??), and so doesn't need to be targeted in consoles. For the tiny niche that will have massive display resolution, they'll be served by high-end PCs.

Yes, let's stop progress! 1080p should be enough for everyone!!

I really don't care about distance, it's irrelvant to me, like the above chart too.
Outside of spec whores who get a hard on for "bigger is better" 4k will be mainly of best use for those with projectors.
I see no reason why a console manufacturer should waste time and resources on it.
The CE industry will push it only if it's cheap to produce and can get people to cycle out their hdtv's.

um, 4K isn't happening for a while and all the UHD/8k talk is at best a marketing stunt.
Outside of movie theaters, you aren't going to find 4k outside of marketing gimmicks for a while. The infrastructure simply isn't there. A vast majority of the 1080p infrastructure hasn't even been amortized yet.

Actually it is exactly the opposite.
The projectors owners get the hard one, while those with tablets and laptops do enjoy higher resolutions, thus quality.
