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.
QHD (Quad HD) or 1440p is a display resolution of 2560 × 1440 pixels. [ 13 ] [ 14 ] The name "QHD" reflects the fact that it has four times as many pixels as HD (720p). It is also sometimes called "WQHD" [ 15 ] [ 16 ] to distinguish it from qHD ( 960 × 540 ), otherwise it is technically redundant since the HD resolutions are all widescreen ...
1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...
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.
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.
The following is a comparison of high-definition smartphone displays, containing information about their specific screen technology, resolution, size and pixel density.It is divided into three categories, containing smartphones with 720p, 1080p and 1440p displays.
The dot pitch of a computer display determines the absolute limit of possible pixel density. Typical circa-2000 cathode-ray tube or LCD computer displays range from 67 to 130 PPI, though desktop monitors have exceeded 200 PPI, and certain smartphone manufacturers' flagship mobile device models have been exceeding 500 PPI since 2014.
1080p Full HD – digital video format with a horizontal resolution of 1920×1080; 1440p – digital video format with a vertical resolution of 1440, aimed at non-television computer monitor usage; 21:9 aspect ratio – a common widescreen cinema aspect ratio; 4K resolution – digital video formats with a horizontal resolution of around 4,000 ...
