The numbers are not entirely random. The numbers represent the number of pixels a screen has in a certain dimension. 1080p stands for 1080pixels vertically. The following number represents a ratio of 1.78 to 1. (16:9)
720x1.78=1280.
1080*1.78=1920
2160*1.78 = 3840. Thats 4k as in about 4000 pixels vertically
It represents the aspect ratio of 16:9 For example a TV standard with 100 pixels would be 100x178.
And a TV 8k standard will be 4320*1.78 unless TV manufacturers decide for a new aspect ratio like 2:1 instead of 16:9 in the future. There is other technical reasoning behind those numbers. Its probably a mix of old conventions and technicalites that formed the exact number of pixels.
