DisplayPort or DP is a unidirectional video and audio transmission protocol. DisplayPort utilizes a state-of-the-art digital protocol and provides an expandable foundation to enable amazing digital display experiences. Designed for low power implementation and high performance, DisplayPort enables the next generation display technology while providing compatibility with existing equipment. DisplayPort is also designed specifically for usage in space-constrained applications like ultra-thin notebooks, netbooks and graphic cards where connector space is at a premium and where display performance really matters.

DisplayPort is an AC-coupled interface. The latest revision of DisplayPort (DP 2.1) is able to transmit up to 20Gbps per lane allowing for 80Gbps bandwidth. Additionally, much like USB, DisplayPort is designed to be backwards compatible back to DP 1.2 (5.4Gbps per lane).
