4096x2160

4096x2160 refers to a resolution commonly called 4K in digital cinema. It has 4096 horizontally and 2160 vertically, for a total of 8,847,360 pixels, and an aspect ratio of 256:135 (approximately 1.896:1). This is wider than the consumer UHD standard of 3840x2160 (16:9).

Defined by the Digital Cinema Initiatives (DCI) as part of its 4K specification, 4096x2160 is used for theatrical projection and distribution to digital cinema projectors. The standard supports high color depth and various chroma subsampling options, typically up to 12-bit color and formats such as 4:4:4 or 4:2:2 in professional workflows. Typical cinema content is delivered and projected at 24 frames per second, with experiments at higher frame rates.

In production, many contemporary digital cinema cameras can capture 4096x2160, forming masters used for distribution and archival. In consumer contexts, 4096x2160 is less common; 3840x2160 is the standard for televisions and many streaming services. When shown on standard 16:9 displays, 4096x2160 content is often letterboxed or downscaled, unless the display or player supports native 256:135 presentation.

Overall, 4096x2160 serves as the cinema-grade 4K resolution offering a wider aspect ratio and higher horizontal resolution than UHD 4K, with usage primarily in film production, mastering, and distribution rather than mainstream consumer displays.
