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.
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 ...
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 ...
The terms "4K" and "Ultra HD" are used more widely in marketing than "2160p". While typically referring to motion pictures, some digital camera vendors have used the term "4K photo" for still photographs, making it appear like an especially high resolution even though 3840×2160 pixels equal approximately 8.3 megapixels, which is not considered ...
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.
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.
It is also used in computer monitors, where the term "21:9" can represent aspect ratios of 43:18 (2.3 8:1 or 21.5:9) and 12:5 (2.4:1 or 21.6:9) in addition to 64:27. The wider screen provides advantages in multitasking as well as a more immersive gaming experience, [ 3 ] [ 4 ] and even wider screens with aspect ratios such as 32:9 (allowing for ...
In the late 1970s and early 1980s, programmers worked within the confines of relatively expensive and limited resources of common platforms. Eight or sixteen kilobytes of RAM was common; 64 kilobytes was considered a vast amount and was the entire address space accessible to the 8-bit CPUs predominant during the earliest generations of personal computers.
