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 2,160 horizontal lines of
display resolution, 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.
