Apart from BT, Amazon Prime, Netflix, YouTube   ;)

It's also called Ultra HD which is how BT brand it. But basically it's 4 times better than standard full HD which could be considered 1k  :y

Thing is you need a big ass TV to get 4K benefit. Needs to be at least a 50" I'd say

I`ve got a full HD 55" Samsung and when shown a 4k model, couldn`t really see what all the hype is about

Even on a 55" set, you've got to have your nose touching the screen to notice it. It's the next marketing gimmick, now that 3D and "smart" TVs have tanked. ;)

tut tut, YOU should know better.

Full HD is 1080p. Or roughly 1920 x 1080 pixels.

4k/UHD/Whatever is 2160p. Or roughly 3800 x 2000 pixels.

This means "4k" as 4 times the pixels, BUT its only double the resolution.  "4k" being something dreamt up by the TV manufacturers (I think Sony came up with it, along with 8k) as a marketing ploy.

Ah,so no real benefit at least to me.Anything much above the 40" tv I've got would dwarf my room,so needing something over 50" would be pointless.Thanks for the info though.

it's basically twice the pixels wider and twice the pixels taller.

At the end of the day it is a little like spending crazy money on hifi, if your eyes / ears ain't up to the job anymore and you don't have the sources, don't bother  ;)
