Strictly speaking, a UHD television cannot achieve the same resolution as a 4K set, since there are fewer horizontal pixels. Therefore, we sometimes use the term 4K2K. The number of vertically-arranged pixels is 2160 (2K) for television sets. 4K refers to a horizontal resolution of 4096 Pixels (4K = 4000). вћЁ 4K: The term originates from cinematic terminology, and, whilst not strictly correct nowadays, is still used for TV.The resolution of UHD is 3840 x 2160 pixels (8,294,400 pixels overall), which is four times higher than that of its predecessor. вћЁ UHD: This abbreviation stands for Ultra High Definition, and is the successor to Full HD.Full HD has a significantly greater pixel density on a 32-inch screen as opposed to a 40-inch screen, and therefore produces a finer-quality image on a smaller screen.

The pixel density is specified in the unit DPI (Dots per Inch). Rather, the resolution is relative to the size of the screen, due to the density of pixels in any given image. It should be noted that pixel specification alone cannot fully indicate how sharp the image on the screen actually appears to the human eye. They have corresponding colour values that create the overall image like a mosaic. Pixels are the building blocks of an image. HD Ready, for example, means that the resolution is at 1280 pixels on the horizontal axis and 720 pixels on the vertical axis. The image resolution is usually indicated by the number of horizontal and vertical pixels, i.e.
