In consumer products, 2560 × 1440 is often incorrectly referred to as "2K", but it and similar formats are more traditionally categorized as 2.5K resolutions. The resolution 1920 × 1080 has also been referred to as a 2K resolution by other standards organizations like NHK Science & Technology Research Laboratories and ITU Radiocommunication Sector (which were involved in the standardization of 1080p HDTV and 4K UHDTV). Usage of the term "2K" predates the publication of the DCI standard. However, the term "2K" itself is generic, was not coined by DCI, and does not refer specifically to the DCI 2K standard. The resolution of the encapsulated video content follows the SMPTE 428-1 standard, : §3.2.1 which establishes the following resolutions for a 2K distribution: : 6 This is the resolution of the 2K container format standardized by DCI in their Digital Cinema System Specification in 2005. Typically this is done at 2048 × 1556, but the exact dimensions vary based on the aspect ratio and size of the scan area. ![]() In the cinematography industry, 2K resolution traditionally refers to a digital scan of 35 mm film with a resolution around 2000 pixels wide. For television and consumer media, 1920 × 1080 is the most common 2K resolution, but this is normally referred to as 1080p. In the movie projection industry, Digital Cinema Initiatives is the dominant standard for 2K output and defines a 2K format with a resolution of 2048 × 1080. 2K resolution is a generic term for display devices or content having a horizontal resolution of approximately 2,000 pixels.
