problem Part 1: 1080p vs 4K

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.
