Super Video Graphics Array, abbreviated to Super VGA or SVGA, [1] [75] [84] also known as Ultra Video Graphics Array early on, [95] abbreviated to Ultra VGA or UVGA, is a broad term that covers a wide range of computer display standards. [96] Originally, it was an extension to the VGA standard first released by IBM in 1987.
The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.
Video standards associated with IBM-PC-descended personal computers are shown in the diagram and table below, alongside those of early Macintosh and other makes for comparison. (From the early 1990s onwards, most manufacturers moved over to PC display standards thanks to widely available and affordable hardware). Comparison of video resolutions.
Comparison of common display resolutions. Ultrawide formats refers to photos, videos, [1] and displays [2] with aspect ratios greater than 2. There were multiple moves in history towards wider formats, including one by Disney, [3] with some of them being more successful than others.
Early 1440p computer displays became commonly available in 2010. Dell's UltraSharp U2711 monitor was released in 2010 as WQHD, with a 1440p widescreen. [1] The 27-inch Apple LED Cinema Display released in 2010 also had a native resolution of 2560 × 1440, as did the Apple Thunderbolt Display which was sold from July 2011 to June 2016.
The EIA/CEA-861-C and -D standards have the first 59 short video descriptors above. EIA/CEA-861-D is used by HDMI 1.3–1.3c. The EIA/CEA-861-E standard has the first 64 short video descriptors above. It is used by HDMI 1.4–1.4b. The CTA-861-F standard has the first 107 short video descriptors above. It is used by HDMI 2.0–2.0b.
Individual still frames extracted from 3840×2160-pixel video footage can act as 8.3 megapixel still photographs, while only 2.1 megapixels at 1080p and 0.9 megapixels at 720p. If the final video resolution is reduced to 2K from a 4K recording, more detail is apparent than would have been achieved from a native 2K recording. [147]
