Difference between 1080p and 2160p 

1080p

1080p (aka Full HD/ FHD and BT.709) is a set of HDTV high-definition video modes characterized by 1080 horizontal lines of vertical resolution and progressive scan(p), as opposed to interlaced, as is the case with the 1080i display standard. The term usually assumes a Wide screen aspect ratio of 16:9, implying a resolution of 1920x1080 (2.1megapixel) often marketed as Full HD.

2160p
2160p is an alternative name for 4K UHD, a resolution supported by UHDTV products and which offers four times the definition of 1080p. The number 2160 stands for a display resolution which has 2160 pixels along the shortest side, while the letter p stands for progressive scan or non-interlaced. In a progressive image, the lines of resolution of the image go from the top of the screen to the bottom. The only planned higher definition format for television is 8K UHD.
