The Mini DisplayPort (MiniDP or mDP) is a miniaturized version of the DisplayPort audio-visual digital interface.
It was announced by Apple in October 2008, and by early 2013 all new Apple Macintosh computers had Mini DisplayPort, as did the LED Cinema Display. However, in 2016 Apple began phasing out the port and replacing it with the new USB-C connector. The Mini DisplayPort is also fitted to some PC motherboards, video cards, and some PC notebooks from Asus, Microsoft, MSI, Lenovo, Toshiba, HP, Dell, and other manufacturers.
