16:9 resolutions in comparison

4K resolution is a generic term for display devices or content having horizontal resolution on the order of 4,000 pixels. [1]

Several 4K resolutions exist in the fields of digital television and digital cinematography. In the movie projection industry, Digital Cinema Initiatives is the dominant 4K standard.

The television industry has adopted ultra high definition television as its 4K standard. As of 2013, some UHDTV models are available to general consumers for under $1000.[2][3] However, due to lack of available content, 4K television has yet to achieve mass market appeal. Using horizontal resolution to characterize the technology marks a switch from the previous generation, high definition television, which categorized media according to vertical resolution (1080i, 720p, 480p, etc.). The top-end regular HDTV format, 1080p, qualifies as 2K resolution, having a horizontal resolution of 1920 pixels, with a vertical resolution of 1080 pixels.

Some modern smartphones are capable of recording video at 4K resolution.[4]

Resolutions

4K Ultra HD

4K UHD is a resolution of 3840 pixels × 2160 lines (8.3 megapixels, aspect ratio 16:9) and is one of the two resolutions of ultra high definition television targeted towards consumer television, the other being 8K UHD which is 7680 pixels × 4320 lines (33.2 megapixels). 4K UHD has twice the horizontal and vertical resolution of the 1080p HDTV format, with four times as many pixels overall.[1][5]

Digital cinema

The Digital Cinema Initiatives consortium established a standard resolution of 4096 × 2160 (8.8 megapixels, aspect ratio ~17:9) for 4K film projection. This is the native resolution for DCI-compliant 4K digital projectors and monitors; pixels are cropped from the top or sides depending on the aspect ratio of the content being projected. The DCI 4K standard has twice the horizontal and vertical resolution of DCI 2K, with four times as many pixels overall.

4K digital films may be produced, scanned, or stored in a number of other resolutions depending on what storage aspect ratio is used.[6][7]

Streaming video

YouTube allows a maximum upload resolution of 4096 × 3072 (12.6 megapixels, aspect ratio 4:3).[8][9]
Vimeo allows videos of 4096 × 3072 to be uploaded.[10]
