1080p (1920 × 1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; [1] the p stands for progressive scan, i.e. non- interlaced.
The first commercial displays capable of this resolution include an 82-inch LCD TV revealed by Samsung in early 2008, [45] the Sony SRM-L560, a 56-inch LCD reference monitor announced in October 2009, [46] an 84-inch display demonstrated by LG in mid-2010, [47] and a 27.84-inch 158 PPI 4K IPS monitor for medical purposes launched by Innolux in ...
Display size. On 2D displays, such as computer monitors and TVs, display size or viewable image size (VIS) refers to the physical size of the area where pictures and videos are displayed. 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.
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 resolution or display modes of a digital television, computer monitor, or other display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode ray tube (CRT) displays, flat-panel displays ...
Image resolution. Image resolution is the level of detail of an image. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved.
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 ...
The aspect ratio of the pixels themselves is known as the pixel aspect ratio (PAR) – for square pixels this is 1:1 – and these are related by the identity: SAR × PAR = DAR. Rearranging (solving for PAR) yields: PAR = DAR / SAR. For example: A 640 × 480 VGA image has a SAR of 640/480 = 4:3, and if displayed on a 4:3 display (DAR = 4:3) has ...
