4K Resolution

4K (or UltraHD) resolution TVs display 3,840 x 2,160 pixels which are used to create the image on the screen. This is four times the number of pixels displayed on a Full HD TV, which displays 1,920 x 1,080. Four times the number of pixels means four times the level of detail. This increase in pixel density adds sharpness and detail, smoother curves and more nuance and realism to an image and allows larger screens to be viewed from closer distances without the grid-like structure of individual pixels becoming visible. (Note Digital cinema systems use 4096 x 2160 resolution, often referred to as DCI 4K)
