The resolution 3840 × 2160, sometimes referred to as 4K UHD or 4K × 2K, has a 16:9 aspect ratio and 8,294,400 pixels. It is double the size of Full HD ( 1920 × 1080 ) in both dimensions for a total of four times as many pixels, and triple the size of HD ( 1280 × 720 ) in both dimensions for a total of nine times as many pixels.
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. [1] Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 3840 × 2160 (4K UHD) with a 16:9 aspect ratio is the dominant 4K standard, whereas the movie projection industry uses 4096 × ...
This bit of marketing obfuscation is calculated as horizontal resolution × vertical resolution × 3. For example: 640 × 480 VGA is 921,600 subpixels, or 307,200 pixels, 800 × 600 SVGA is 1,440,000 subpixels, or 480,000 pixels, and 1024 × 768 XGA is 2,359,296 subpixels, but only 786,432 full-color pixels. ^ Apple Computer 1 megapixel standard.
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. It is expressed as two numbers separated by a colon (x: y), where x corresponds to the width and y to the height. Common aspect ratios for displays, past and present, include 5:4 ...
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 ...
The interlaced (i or I) mode produced visible flickering of finer details, eventually fixable by use of scan doubler devices and VGA monitors. 720×480i/576i maximum. Typically 640×400i/512i or 640×200/256 NI, and 320×200/256 NI for games. 720.
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 "p-display" nomenclature used in this article refers to the number of pixels ...
