8k has 16 times as many pixels as 1080p.Hmm? You only need 2 times 4K resolution to get 8K resolution. Am I reading something wrong here?
4K = 4 times 1080p, 8K = 8 times 1080p (in terms of pixels)

4K = 4 times 1080p, 8K = 8 times 1080p (in terms of pixels)
4K UHDTV (2160p) has a resolution of 3840 ? 2160 (8.3 megapixels), 4 times the pixels of 1080p.
8K UHDTV (4320p) has a resolution of 7680 ? 4320 (33.2 megapixels), 16 times the pixels of current 1080p HDTV, which brings it to roughly the detail level of 15/70mm IMAX. NHK advocates the 8K UHDTV format with 22.2 surround sound as Super Hi-Vision.
Stolen fromhttp://www.neowin.net/news/itu-appro...-specification. No direct references cited. There's more there, and they go further in depth than I really care to try to understand. I can't imagine "needing" this anytime soon, even though my TV's bigger than 42".At 9 ft distance, pixel spacing must be 0.0094247 inches or less. For 1080p set, this equals to 18.09'' width or less. With Pythagorean theorem we can find out diagonal measurement. It is ~21''.
So, at 9 ft viewing distance, 1080p TV set is meeting visual limitations of healthy observers when TV set diagonal measurement is 21 inches or less. That means you'll benefit from 4K (2160p to be precise) if your TV is bigger than 21 inches.
Let's see when a 4K TV set meets this requirement, for 9 ft viewing distance too.
At 9 ft distance, pixel spacing must be 0.0094247 inches or less. For 4K (2160p) set, this equals to 36.19'' width or less. With Pythagorean theorem we can find out diagonal measurement. It is ~42''.
So, at 9 ft viewing distance, 4K (2160p) TV set is meeting visual limitations of healthy observers when TV set diagonal measurement is 42 inches or less. That means you'll benefit from 8K (4320p to be precise) only if your TV is bigger than 42 inches.
U MAD UR BLU RAYS DONT HAVE 4KSchart is BS created by losers who want to feel better about having shitty 720p TVs
