The Mini DisplayPort (MiniDP or mDP) is a miniaturized version of the DisplayPort audio-visual digital interface. The functionality and signals are identical. Apple announced the Mini DisplayPort in October 2008. As of November 17, 2013, Apple fit the port to the LED Cinema Display and all new Macintosh computers: MacBook, MacBook Pro, MacBook Air, iMac, Mac mini, Mac Pro, and Xserve.[2][not in citation given] The Mini DisplayPort is also fitted to some PC notebooks from various manufacturers including Asus, Microsoft, Lenovo, Toshiba, HP, and Dell. It is also fitted to some recent motherboards.
Unlike its Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort is capable of driving display devices with resolutions up to 2560×1600 (WQXGA). With a passive adapter, the Mini DisplayPort can drive display devices with VGA, DVI, or HDMI interfaces.[3][4][5]
Apple offers a free license for the Mini DisplayPort[6] but they reserve the right to cancel the license should the licensee "commence an action for patent infringement against Apple".[7]
