In television and consumer media, 3840x2160 (4K [[Ultra-high-definition television|UHD]]) is a common 4K standard. The [[Movie projector|movie projection]] industry uses 4096x2160 ([[Digital Cinema Initiatives|DCI]] 4K). The 4K used for iMac's display is 4096 x 2304 px. 4K is generally considered to be the upgrade to [[1080p]] (1920x1080). The advantages of 4K are that the display has four times more pixels than 1080p which allows the picture to be clearer. ==References== {{reflist}} [[Category:Display technology]] [[Category:Movie terminology]] {{tech-stub}}
