The vertical resolution is usually a multiple of 8 or 16 pixels due to most video codecs processing pixels on such sized blocks. A widescreen FHD video can be 1920 × 800 for a 12∶5 ratio or 1920 × 1040 for roughly 1.85 × 1 , for instance.
Effectively 1/16 the total resolution (1/4 in each dimension) of "Full HD", but with the height aligned to an 8-pixel "macroblock" boundary. Common in small-screen video applications, including portable DVD players and the Sony PSP. 480×272 (131k) 480 272 130,560 ~1% narrower than 16:9 (30:17 exact) Mac Mono 9" Original Apple Macintosh display
As of 2016, most computer monitors use widescreen displays with an aspect ratio of 16:9, [5] although some portable PCs use narrower aspect ratios like 3:2 and 16:10 [6] while some high-end desktop monitors have adopted ultrawide displays. [7] The following table summarises the different aspect ratios that have been used in computer displays:
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 ...
In the case of the 16:9 ratio, with 240 pixels high, the horizontal resolution should be 240 / 9 × 16 = 426. 6 (426 2 ⁄ 3), the closest multiple of 16 is 432. WQVGA has also been used to describe displays that are not 240 pixels high, for example, Sixteenth HD1080 displays which are 480 pixels wide and 270 or 272 pixels high.
The GDI system in Windows is pixel-based and thus not resolution-independent. To scale up the UI, Microsoft Windows has supported specifying a custom DPI from the Control Panel since Windows 95. [4] (In Windows 3.1, the DPI setting is tied to the screen resolution, depending on the driver information file.) When a custom system DPI is specified ...
AMD Eyefinity-driven multi-monitor system for gaming. Early versions of Doom permitted a three-monitor display mode, using three networked machines to show left, right, and center views. [8] More recently, games have used multiple monitors to show a more absorbing interface to the player or to display game information.
While 16:9 (1.7 7:1) was initially selected as a compromise format, the subsequent popularity of HD broadcast has solidified 16:9 as perhaps the most common video aspect ratio in use. [7] Most 4:3 (1.3 3 :1) and 21:9 video is now recorded using a " shoot and protect " technique that keeps the main action within a 16:9 (1.7 7 :1) inner rectangle ...
