Jump to: navigation, search

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 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.[2] The only planned higher definition format for television is 8K UHD.[3]

Overview[edit]

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[edit]

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