Before we go further, let's make it clear the terms of 4K resolution and 1080p. The biggest difference between 4K and 1080p lies in the resolution. 4K has a resolution of 3840 * 2160, yet 1080P has only 1920*1080 pixels. So, compared to a 1080P TV, a 4K screen has four times the number of pixels than that of a 1080P screen and that’s why 4K looks much more sharp and delicate than 1080p.
