16:9 is a widescreen aspect ratio with a width of 16 units and height of 9 units. Once seen as an "exotic" aspect ratio, [ 1 ] since 2009, it has become the most common aspect ratio for televisions and computer monitors , and is also the universal standard image format for the universal 1080p , 2160p and 4320p formats.
The first popular widescreen ratio for computer displays was 16:10, and 16:9 has been the most common ratio since 2012. The display aspect ratio ( DAR ) is the aspect ratio of a display device and so the proportional relationship between the physical width and the height of the display .
Largely between the 1990s and early 2000s, at varying paces in different countries, 16:9 (e.g. 1920×1080p 60p) widescreen displays came into increasingly common use by high definitions. With computer displays, aspect ratios other than 4:3 (e.g. 1920×1440) are also referred to as "widescreen".
480p is the shorthand name for a family of video display resolutions.The p stands for progressive scan, i.e. non-interlaced.The 480 denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio (480 × 4 ⁄ 3 = 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) [1] pixels for an approximate 16:9 aspect ...
Find the optimal distance for a given screen. Example: for a 4K UHD screen 140 cm high (112 inches diagonal), the optimal distance is 140 × 1.6 = 224 cm. Find the right screen size. Example: for a 1080 HDTV used at a distance of 250 cm, you need to find a screen whose height is close to 250 / 3.2 = 78 cm (63 inches diagonally).
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 size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, typically measured in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels .
The ratio of the width to the height of an image is known as the aspect ratio, or more precisely the display aspect ratio (DAR) – the aspect ratio of the image as displayed; for TV, DAR was traditionally 4:3 (a.k.a. fullscreen), with 16:9 (a.k.a. widescreen) now the standard for HDTV.
