( p2) Several different 4K resolutions have been standardized by various organizations. DCI Digital Cinema System Specification [ ] In 2005, (DCI), a prominent standards organization in the cinema industry, published the Digital Cinema System Specification. This specification establishes standardized 2K and 4K container formats for digital cinema production, with resolutions of 2048 × 1080 and 4096 × 2160 respectively. ( §4.3.1) The resolution of the video content inside follows the SMPTE 428-1 standard, ( §3.2.1) which establishes the following resolutions for a 4K distribution: ( p6) • 4096 × 2160 (full frame, 256∶135 or ≈1.90∶1 aspect ratio) • 3996 × 2160 (flat crop, 1.85∶1 aspect ratio) • 4096 × 1716 (CinemaScope crop, ≈2.39∶1 aspect ratio) 2K distributions can have a frame rate of either 24 or 48, while 4K distributions must have a frame rate of 24 FPS. ( §3.1.4.2) Some articles claim that the terms '2K' and '4K' were coined by DCI and refer exclusively to the 2K and 4K formats defined in the DCI standard.

Critics state that at normal direct-view panel size and viewing distances, the extra pixels of 4K are redundant at the ability of. Projection home cinemas, on the other hand, employ much larger screen sizes without necessarily increasing viewing distance to scale. JVC has used a technique known as 'e-shift' to extrapolate extra pixels from 1080p sources to display 4K on screens through or from native 4K sources at a much lower price than native 4K projectors.
