The Mini DisplayPort (MiniDP or mDP) is a miniaturized version of the DisplayPort audio-visual digital interface. Mini DisplayPort is capable of driving display devices with resolutions up to 2560x1600. Mostly used in new Apple computers: MacBook, MacBook Pro, MacBook Air, iMac, Mac mini, Mac Pro, and Xserve, but also fits to some PC notebooks.

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 and 5 while lane 0 will be on pin 10 and 12.

With a passive adapter, the Mini DisplayPort can drive display devices with VGA, DVI, or HDMI interfaces.
