DisplayPort is a new digital display interface standard (approved May 2006) being put forth by the VESA (Video Electronics Standards Association). It defines a new license-free state-of-the-art digital audio/video interconnect, intended to be used primarily between a computer and its display-monitor, or a computer and a home-theater system.

DisplayPort connector supports 1 to 4 data pairs at main link that also carries audio and clock signals, with transfer rate of 1.62 or 2.7 gigabits per second. Video signal supports 8 or 10 bit pixel format per colour channel. A bi-direction auxiliary channel runs at constant 1 megabits per second, serves as Main Link management and device control using VESA EDID and VESA MCCS standards. Video signal is not compatible with DVI or HDMI.

DisplayPort includes optional DPCP (DisplayPort Content Protection) copy-protection from Philips, which uses 128-bit Advanced Encryption Standard encryption, with secure modern ciphers. It also features full authentication and session key establishment (each encryption session is independent). There is an independent revocation system. This portion of the standard is licensed separately.

The existing competitor for this new interface standard is the increasingly-common HDMI connector (with HDCP copy-protection). A possible future competitor is Unified Display Interface.

Advantages

10 Gbit/s forward link channel supports high resolution monitors, 2560x1600, with single cable. Note: 70fps*24bpp*2560*1600=6.9 Gbit/s.
Royalty free except for encryption portion. HDMI is not.
Open and extensible standard to help with broad adoption.
Supports increased color depth of 10, 12 and 16 bits.
Full bandwidth transmission for 3 meter cable.
Reduced bandwidth transmission, 1080p, for 15 meter cable.
DisplayPort connector assists in blind connection by just feeling.
Supports internal and external connections so that one standard can be used by computer makers reducing costs.[link]
