First of all, what is 4K?4K resolution, that is, the Utlra HD standard. As a standard, the 4K image refers to the horizontal direction, each row of pixel values reached or close to 4096 images, in most cases, especially 4096*2160 resolution. And according to the range of use, 4K imagesThere are also a variety of derivative resolutions, such as Full, Aperture, 4K, 4096*3112, and AcademyThe 3656*2664 of 4K and the standard UHDTV of 3840*2160 belong to the category of 4K image resolution. Today, the common 4K resolution is 4096*2160 and 3840*2160 two, the former is mainly used in the field of digital cinema, the latter is used in 4K TVOr on the 4K monitor.
