4K resolution, also called 4K, refers to a display device or content having horizontal resolution on the order of 4,000 pixels. Several 4K resolutions exist in the fields of digital television and digital cinematography. In the movie projection industry, Digital Cinema Initiatives (DCI) is the dominant 4K standard. 4K has become the common name for ultra-high-definition television (UHDTV), although its resolution is only 3840 x 2160 (at a 16:9, or 1.78:1 aspect ratio), which is lower than the movie projection industry standard of 4096 x 2160 (at a 19:10 or 1.9:1 aspect ratio). The use of width to characterize the overall resolution marks a switch from the previous generation, high definition television, which categorized media according to the vertical dimension instead, such as 720p or 1080p. Under the previous convention, a 4K UHDTV would be equivalent to 2160p.

Now, another transition is underway: the conversion to 2160p resolution (3840 x 2160 pixels), otherwise known as 4K or Ultra HD. At the moment, 4K is a chicken-and-egg dilemma: 4K televisions won't be widely adopted until there is 4K content, and studios or TV providers won't make much 4K content available until there is a solid base of 4K televisions. But some companies have already begun or will soon provide 4K content, often working in tandem with TV makers. Here is the current and nearfuture state of 4K/Ultra HD. Where can I get 4K video today?
