4K: the not so distant future of tv

Very nice technology. I have seen the 65-inch Sony 4K TV demo at local Fry's stores. It looks quite detailed, but you have to be VERY close (about 3-4 feet away from that 65-inch screen, maximum!) to see the difference. Further away than that, and a 1080P set is good enough.

Was it running true 4k content or upconverted stuff?

This article cuts the hype: http://www.theregister.co.uk/2013/06..._eyes_have_it/

An important message is that if you want any real benefit from 4K or 8K then you need a higher frame rate. Still pictures can use the full resolution but as soon as anything moves you lose a lot.

I saw a demo of NHK ultra high resolution TV during the Olympics. Not sure whether the screening was in 4K or 8K nor do I know the frame rate but it was impressive. On a big screen with wide angle shots you could see all the detail. It was like sitting in one of the best seats in the stadium.

I wouldn't think you'd necessarily need a higher frame rate, but you'd definitely need a better bit rate than that at which current high-def video is encoded.

EDIT: Ah, I see what you mean, though, now that I've read the article. Yes, motion blur would still be a factor at 4K resolution given current frame rates.

The demos at the Fry's stores are using true 4K video from a media-player box, to the best of my knowledge. It was definitely clearer than 1080P video.

The sony media player is out, looks like a rip off if u ask me. It's a hard drive.

The 4k files are so freaking enormous, there is no disk.
