List of common display resolutions

2K resolution is a generic term for display devices or content having horizontal resolution of approximately 2,000 pixels.[1] In the movie projection industry, Digital Cinema Initiatives is the dominant standard for 2K output and defines 2K resolution as 2048 × 1080.[2][3]

In television and consumer media, 1920 × 1080 is the most common 2K resolution, but this is normally referred to as 1080p.

Resolutions[edit]

Format Resolution Display aspect ratio Pixels
DCI 2K (native resolution) 2048 × 1080 1.90:1 (256:135, ~17:9) 2,211,840
DCI 2K (flat cropped) 1998 × 1080 1.85:1 2,157,840
DCI 2K (CinemaScope cropped) 2048 × 858 2.39:1 1,755,136

Comparison to 1080p[edit]

1080p has the same vertical resolution (1080 pixels) as, but a 7% smaller horizontal resolution (1920 vs. 2048) than DCI 2K resolutions.[4] Though the difference is slight, DCI and industry standards distinguish the two in their terminology.[2][3][5][6]
