We will take a look at the relationship between resolution and screen size, as well as pixel density and the latest technology trends.
It is predicted that 4K will replace HD as the mainstream resolution in the next few years. 4K, of course, stands for 4,000 and refers to a horizontal pixel count of about that number. Currently, there are two standards for 4K resolution, namely "DCI 4K" and "UHD 4K".
DCI 4K corresponds to twice the resolution of 2048 x 1080 pixels in projectors (4096 x 2160/approx. 17:9) and is the film industry's 4K resolution. UHD 4K (also called UHDTV 4K), on the other hand, is the television industry's 4K resolution as defined by the International Telecommunication Union (ITU). It has twice the horizontal resolution of 1920 x 1080 pixels at HD (3840 x 2160/16:9).
