Pinout diagram of the Mini DisplayPort connector
Mini DisplayPort is a smaller version of the DisplayPort connection interface specified by the Video Electronics Standards Association (VESA). Despite its small size, Mini DisplayPort has a full 20 pins and can support up to a 30-inch display with a 2560 by 1600 screen resolution.
History[]
Mini DisplayPort was released by Apple in October 2008. Apple used the port in the MacBook family and its desktop line. The connector was used by Apple and was freely licensed to third party manufacturers that agreed not to contest Apple's patents.[1]. Adapters can allow it to support other video connectors, such as HDMI and VGA.
In 2011, Mini DisplayPort was superseded by the Thunderbolt port, which used the same connector type. Thunderbolt 3 and 4 switched to the USB-C form factor.
