Allows easy expansion of the Display Port standard.

In a separate entity connection allows multiple video streams (in the future).

Design to support the connection between internal chips.   

Allow directly operating display function options, will be able to remove the control loop of display to produce cheaper and lighter display.

The goal is to replace the internal LVDS connection in notebook computer panel by the unified connection interface.

Allow backward compatibility in single channel DVI/HDMI. Dual channel DVI/HDMI and analogy VGA adapter need conversion adapter.

Support RGB and YCbCr color space (ITU-R BT.601 and BT.709 format).

The auxiliary channel can be used in the touch panel data, USB connection, camera, microphone and other equipment.

Less channel and embedded time pulse reduce radio interference "RFI".
