Description 4K is not standardized description of a number of physical pixels. It’s an approximation of the number of pixels wide something is (as opposed to the previous convention of how many pixels tall as in 480p, 720p, 1080p, etc.). Something with somewhere around 4000 pixels wide will be called 4K. So you have a variety starting from 3840 pixels up to at least 5120 pixels on “ultrawide 4K” displays, broadcasts, or video. Display resolution of a computer monitor, tablet, laptop, smartphone or any other display device is the number of distinct pixels in each dimension that can be displayed. High-density monitors or Retina monitors sold by Apple are generally recognized as having a physical pixel density greater than 200 pixels per inch. This means that they have twice the pixel density of a classic resolution computer monitor. 4K monitors for PCs hit the shelves in 2014, and understanding pixel density has become important when choosing products along with screen size and resolution. Pixel density is the specification that defines how detailed a display is. It is expressed in units of PPI (Pixels Per Inch). Latest activities Tags |
