2160p

2160p is an alternative name for 4K UHD, a resolution supported by UHDTV products and which offers four times the definition of 1080p.^[1] 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.^[2] The only planned higher definition format for television is 8K UHD.^[3]

Overview

2160p or 4K UHD is 3840×2160 (8.3 megapixels in the 16:9 aspect ratio) and is one of the two resolutions of Ultra-high-definition television.^[4]^[5]

Confusion between QHD and UHD

QuadHD or QHD are 1440p, not the higher 2160p (UHD) standard. Quad HD is four times the resolution of HD or 'HD Ready' (720p),^[6] whereas UHD is four times the resolution of Full HD (1080p).^[7]
