DisplayPort(DP) is a newly used digital display interface standard guided by the Video Electronics Standards Association (VESA).  DP was first approved on May 2006. The latest version 1.1a was released by VESA for April 2, 2007.

Displayport is defined as a new, high-definition digital audio/video interconnect for computing displays, graphic cards, and laptops.

With a 34% PCs market penetration forecast in 2010, Displayport is expected to replace DVI and VGA, or even the HDMI equivalent for computers systems.


DisplayPort supports the following features:

1) Support a maximum of 10.8Gbit/s and 2560 x 1600 resolutions

2) Support a minimum of 1080p resolution at 24bpp, 50/60 Hz over 4 lanes at 15 meters

3) Provide both digital video and audio in one cable

4) Support industry standard colorimetry specifications for consumer electronics devices including RGB and YCbCr 4:2:2 and YCbCr 4:4:4

5) Support up to 8 channels of LPCM coded audio at 192 kHz with a 24 bit sample size

6) Composites of smaller connector footprint than either DVI or VGA

7) Support HDCP(High-Definition Content Protection) which uses 128-bit AES encryption

8) Support hot plug and un-plug detection and link status-failure detection

9) Support the 1Mbps bidirectional auxiliary channel
