Display resolutions

2K resolution is a generic term for display devices or content having horizontal resolution of approximately 2,000 pixels.[1] Digital Cinema Initiatives (DCI) defines 2K resolution standard as 2048×1080.[2][3]

In the movie projection industry, DCI is the dominant standard for 2K output.

Comparison to 1080pEdit

Occasionally, 1080p (Full HD or FHD) has been included into the 2K resolution definition. Although 1920x1080 could be considered as having a horizontal resolution of approximately 2,000 pixels, most media, including web content and books on video production, cinema references and definitions, define 1080p and 2K resolutions as separate definitions and not the same.

Although 1080p has the same vertical resolution as DCI 2K resolutions (1080 pixels), it has a smaller horizontal resolution below the range of 2K resolution formats.[4]

According to official reference material, DCI and industry standards do not officially recognize 1080p as a 2K resolution in literature concerning 2K and 4K resolution.[2][3][5][6]
