DisplayPort™ (DP) standard specifies an open digital communications interface for use in both internal connections, such as interfaces within a PC or monitor, and external display connections. Suitable external display connections include interfaces between a PC and monitor or projector, between a PC and TV, or between a device such as a DVD player and TV display.
DisplayPort™ (DP) is an industry standard to accommodate the growing broad adoption of digital display technology within the PC and CE industries. It consolidates internal and external connection methods to reduce device complexity, supports necessary features for key cross industry applications, and provides performance scalability to enable the next generation of displays featuring higher color depths, refresh rates, and display resolutions.
The specification is divided into three categories that reflect the ultra high bit rates 10 (10Gbps/lane), ultra high bit rates 13.5 (13.5Gbps/lane), ultra high bit rates 20 (20Gbps/lane).
