4K/UHD is an "umbrella term" that encompasses higher resolutions (more pixels:3840 x 2160P ) than FHD(1920x1080P), as well as more realistic color(10bit(D), 1.06Billon colors) and higher frame rates(PAL 100 Hz /NTSC 120 Hz).

4K/UHD means the digital signage's screen has a minimum resolution of 3,840 pixels wide and 2,160 pixels high, making it the equivalent to two 1080p screens in height and two in length. This resolution was originally known as "Quad HD," and it's used by basically every 4K display. Another resolution, known as 4Kx2K (4,096x2,160 pixels), is used by some projectors and many professional cameras. It also falls under the umbrella of 4K/UHD.

With 4K/UHD, the digital signage can display the video which the previous ones have never achieved.
