Resolutions

Comparison to 1080p

Occasionally, 1080p 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, it has a smaller horizontal resolution below the range of 2K resolution formats.
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.
