Apple Moves Smaller with Mini DisplayPort

The Mini DisplayPort interface is a smaller version of the traditional DisplayPort plug and connector, and was first publicly announced by Apple in 2008. Apple products featuring the Mini DisplayPort connector include the MacBook family of laptops, the iMac, Mac Mini, Mac Pro and the entire Apple Cinema line of displays. The user-friendly Mini DisplayPort connector links the Mac to an LED display, and offers both video and audio support, significantly reducing the number of cables associated with incorporating an external display and speakers.

Large displays are becoming more common as DisplayPort integrators Dell and Apple recently released 30 inch product offerings. Laptops with a Mini DisplayPort can connect a computer with to an external display or projector with a VGA or DVI interface by using an adapter.
In early 2009, VESA announced that it would include Mini DisplayPort in the DisplayPort 1.2 specification.
