What is 4K and 8k Ultra HD Resolution?
4K refers to one of two resolutions. 3840 x 2160, or 4096 x 2160. It is 4 times the resolution of 1080p. This will also allow much higher zoom rates on stills taken from any video clips and minor digital zoom of video streams to be applied without losing much noticeable detail on most monitors. 8K doubles the numbers again, to a resolution of 7,680 by 4,320. That's four times the number of pixels as 4K, which means it's 16 times that of a 1080p TV.
