DisplayPort  connector

DisplayPort connector is a digital display interface developed by the Video Electronics Standards Association. The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to carry audio, USB, and other forms of data
DisplayPort is the first display interface to rely on pocketed data transmission, a form of digital communication found in technologies include Ethernet, USB, and PCI Express. It allows both internal and external display connections and, unlike legacy standards where differential pairs are fixed to transmitting a clock signal with each output, the DisplayPort protocol is based on small data packets known as micro packets, which can embed the clock signal within the data stream, allowing higher resolutions with fewer pins.  The use of data packets also allows DisplayPort to be extensible, meaning additional features can be added over time without significant changes to the physical interface itself.

Mini DisplayPort

Mini DisplayPort

Mini DisplayPort is a standard announced by Apple in the fourth quarter of 2008. Shortly after  announcing the Mini DisplayPort, Apple announced that it would license the connector technology with no fee. The following year, in early 2009, VESA announced that Mini DisplayPort would be included in the upcoming DisplayPort 1.2 specification. On 24 February 2011, Apple and Intel announced Thunderbolt,  a successor to Mini DisplayPort which adds support for PCI Express data connections while maintaining backwards compatibility with Mini DisplayPort based peripherals.


Technical specifications:
Forward link channel with 1 to 4 lanes; effective data rate 1.296 (reduced bit rate), 2.16 (high bit rate), 4.32 (HBR2), or 6.48 Gbit/s (HBR3) per lane (total 5.184, 8.64, 17.28, or 25.92 Gbit/s for a 4-lane link)†.
8b/10b encoding provides DC-balancing and Embedded Clock within serial channel (10 bit symbols, 20% coding overhead)
