^True, but there is definitive gearing up towards 4K. Technology will soon make it cheap.

Terrible idea.  For comfort reasons alone I want to move close to a window and look around.  Particularly in a sealed tube.  Imagine there's an electrical failure and you're completely blacked out on a runway.  Oh now THAT'LL be a great feeling.

 

I'm going to pass on buying that plane in 2018.

I think it's a good idea except it won't match what you're eyes would see. You'll be looking at and focusing at a screen very near you instead of through a window to something far away. And it will probably be in 2D and will have a lower frame rate than real life. It should look better the further you are from the screen/"window".

Good - I'd rather skip 4K and go directly to 8K.

I like the powers of 2 to be even. Computer scientists tend to be this way.  0 to 8191 is expressable in 13bits width.  Ick.  I want 2^2, 2^4, etc.  Give me true 16,384 across please.  I know, I know, it's not 8192, etc...

Even powers of 2 went out of style with the 128mb DRAM. :-)

DRAMs use multiplexed addressing (row/column) and the chip capacity increased by a factor of 4 (1K, 4K, 16K, 64K, 256K, 1M, 4M, 16M, 64M). "Even" powers of 2! Then somebody said - this is silly, screw it, and followed the 128M, 256M, 512M, 1G, 2G, 4G.

Funny how whenever one format makes inroads, the rumor mill churns on to the next format.

Seriously though, 8K will be a really really tough sell. When some claim they can't see the difference going from 2K>4K, good luck selling 8K.

8K will be a tough sell, but consider a 16K 65" TV with the frame all black and one lit up pixel.

If it's only moderately lit you likely won't see it from the couch. But if it were putting out amazing amounts of light it could be far far smaller and you'd still see it.

We're looking at resolution entirely incorrectly whenever we start digging out the old spatial acuity calculations for eye charts.

Marketing machine will invent selling slogans and gimmicks: e.g. 'wonderfully silky smooth 8K pixels' vs. 'old roughly chopped 4K pixels bad for the eyes'

Yes, and a similar comparison is to consider the light output from an area of the size of one 1080 size pixel on the screen. That area on a 4k or 8k screen will have more pixels, hence more light (and more colors), other things being equal on a pixel-by-pixel basis.

Sure, but my point is addressing the whole "it's too small thing". That the sheer amount of light output has more to do with whether or not you'll see something...even something that is technically too angularly small to see otherwise. Something "too small to see" can be seen if bright enough.
