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 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.
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 base resolution increased by increasing the width and keeping the height constant, for square or near-square pixels on a widescreen display, usually with an aspect ratio of either 16:9 (adding an extra 1/3rd width vs a standard 4:3 display) or 16:10 (adding an extra 1/5th).
5K resolution refers to display formats with a horizontal resolution of around 5,000 pixels. The most common 5K resolution is 5120 × 2880 , which has an aspect ratio of 16∶9 with around 14.7 million pixels (just over seven times as many pixels as 1080p Full HD ), with exactly twice the linear resolution of 1440p and four times that of 720p .
Common aspect ratios for displays, past and present, include 5:4, 4:3, 16:10, and 16:9. To distinguish: The display aspect ratio (DAR) is calculated from the physical width and height of a display, measured each in inch or cm (Display size). The pixel aspect ratio (PAR) is calculated from the width and height of one pixel.
An array of 1280 × 720 on a 16:9 display has square pixels, but an array of 1024 × 768 on a 16:9 display has oblong pixels. An example of pixel shape affecting "resolution" or perceived sharpness: displaying more information in a smaller area using a higher resolution makes the image much clearer or "sharper".
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 ...
