LG To Show Off New 55-Inch 8K Display at CES
MojoKid writes One of the most in-your-face buzzwords of the past year has been "4K," and there's little doubt that the forthcoming CES show in early January will bring it back in full force. As it stands today, 4K really isn't that rare, or expensive. You can even get 4K PC monitors for an attractive price. There does remain one issue, however; a lack of 4K content. We're beginning to see things improve, but it's still slow going. Given that, you might imagine that display vendors would hold off on trying to push that resolution envelope further – but you just can't stop hardware vendors from pushing the envelope. Earlier this year, both Apple and Dell unveiled "5K" displays that nearly doubled the number of pixels of 4K displays. 4K already brutalizes top-end graphics cards and lacks widely available video content, and yet here we are looking at the prospect of 5K. Many jaws dropped when 4K was first announced, and likewise with 5K. Now? Well, yes, 8K is on its way. We have LG to thank for that. At CES, the company will be showing-off a 55-inch display that boasts a staggering 33 million pixels — derived from a resolution of 7680x4320. It might not be immediately clear, but that's far more pixels than 4K, which suggests this whole "K" system of measuring resolutions is a little odd. On paper, you might imagine that 8K has twice the pixels of 4K, but instead, it's 4x.
THAT CHART IS WRONG.
Seriously, I can easily see jaggies where it says I shouldn't be able to, IT IS WRONG by a large factor.

So what genius decided to switch us over to the horizontal resolution?
Digital theater projection has used the 2K and 4K terms for a very long time. Nevermind that going to a 2K digital theater is little better than watching a 1080p TV, 4K is the gold standard for theater because it approaches/surpasses the projection quality limit for 35mm (by the time you account for grain, film copying, and sharpness). I'm not saying 35mm can't hold more detail, but the signal to noise ratio is low beyond that.
4K is a big deal because it matches the best visual experience you can get in the theater. You may say that you don't even need higher than 1080p, but Apple started it with their "retina" display. We've hit and surpassed the Nyquist limit in digital sound a long time ago. Apple's phone display reminded people that this is now getting very possible with video.
