How is 4k (2160p) four times more than 1080p? its only double.

1920 x 2 = 3840
1080 x 2 = 2160

???

Detailed descriptions would be nice thanks

The horizontal is 2x and the vertical is 2x, and 2x2=4

In addition the total number of pixels at 3840x2160=8,294,400 and the total number of pixels at 1920x1080=2,073,600

8,294,400 divided by 2,073,600 = 4!!!
