4K is a variety of new resolutions coming out that pretty much center around a 4000 pixel side. There are a couple variants of the 4K resolution.
- 4K Ultra HD - 3840 pixels × 2160 lines (8.3 megapixels, aspect ratio 16:9) - for UHDTV
- 4K Film - 4096 × 2160 (8.8 megapixels, aspect ratio ~17:9)
- Streaming Video - YouTube 4096 × 3072 (12.6 megapixels, aspect ratio 4:3), Vimeo 4096 × 3072 to be uploaded. Netflix will stream 4K sometime in 2014 reportedly, no specifications.
In comparison to current 1080 resolutions or roughly 2.1 megapixels, 4K will be roughly 8.3 megapixels, about four times as much.
If you do a small bit of looking, you will find that the human eye goes way beyond 8.3 megapixels, so asking whether or not the human eye can perceive the difference between 1080 and 4K has already been established.
Why Do We Need it?
Because the television manufacturers say so, might be the thought on the minds of many. It's true that TV manufacturers seem to latch on to something new every year and then cram it down the throats of consumers, see 3DTV.
Do we need it? Sure, the content will look all that much better, for the consumer that has a 4K screen and a setup that will allow the 4K content to get to the screen. How many of you have a 4K screen currently? Not many I'll wager. Television prices are ridiculously high still, most people won't be buying them this year, maybe not even next year. But if you've been lucky enough to attend a CES in the past couple years, you've seen a 4K TV in action. It's extremely impressive. They seem extremely bright and the images are indeed quite a deal better than 720p and 1080p for that matter.
