|This is the pinout for the source-side connector; the sink-side connector pinout will have lanes 0–3 reversed in order, i.e. lane 3 will be on pin 3(n) and 5(p) while lane 0 will be on pin 10(n) and 12(p).|
The Mini DisplayPort (MiniDP or mDP) is a miniaturized and less common 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.
Apple offers a free license for the Mini DisplayPort but they reserve the right to cancel the license should the licensee "commence an action for patent infringement against Apple".
Unlike its Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort can drive display devices with resolutions up to 2560×1600 (WQXGA) in its DisplayPort 1.1a implementation, and 4096×2160 (4K) in its DisplayPort 1.2 implementation. With an adapter, the Mini DisplayPort can drive display devices with VGA, DVI, or HDMI interfaces.
Apple replaced the DVI port from the MacBook, MacBook Air, MacBook Pro, iMac, Mac Mini, and the Mac Pro with the Mini DisplayPort. Its use as the video connector for the 24-inch Cinema Display may complicate compatibility:
