It is used for multiple anamorphic formats and DCI 1024:429 (21. 482517:9), but also for ultrawide computer monitors, including 43:18 (21 1 ⁄ 2:9) for resolutions based on 720 lines and 12:5 (21 3 ⁄ 5:9) for ultrawide variants of resolutions based either on 960 pixels width or 900 lines height.
There are other, non-standard display resolutions with 1080 lines whose aspect ratios fall between the usual 16∶9 and the ultra-wide 64∶27, e.g. 18∶9, 18.5∶9, 19∶9 and 19.5∶9. They are mostly used in smartphones or phablets and do not have established names, but may be subsumed under the umbrella term ultra-wide (full) HD.
A 21:9 display is able to present all content up to 'Scope aspect ratios at equal height, with changing vertical bars to the left and right of the image. Note how the large center circle, representing the main image area, remains at a constant size on the 21:9 display, while it changes on the other two depending on the aspect ratio of the content.
The data format is defined by a standard published by the Video Electronics Standards Association (VESA). The EDID data structure includes manufacturer name and serial number, product type, phosphor or filter type (as chromaticity data), timings supported by the display, display size, luminance data and (for digital displays only) pixel mapping ...
This chart shows the most common display resolutions, with the color of each resolution type indicating the display ratio (e.g., red indicates a 4:3 ratio). This article lists computer monitor, television, digital film, and other graphics display resolutions that are in common use. Most of them use certain preferred numbers.
2K resolution is a generic term for display devices or content having a 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 a 2K format with a resolution of 2048 × 1080 .
This is the proper mode to display anamorphic video. If used for standard aspect ratio video, everything on the screen will appear wider than normal. Contrast this with anamorphic video displayed without processing on a 4:3 display, in which people on the screen will appear taller than normal. This is also known as the 16:9 mode.
The second-generation Macintosh, launched in 1987, came with colour (and greyscale) capability as standard, at two levels, depending on monitor size—512×384 (1/4 of the later XGA standard) on a 12" (4:3) colour or greyscale (monochrome) monitor; 640×480 with a larger (13" or 14") high-resolution monitor (superficially similar to VGA, but at ...
