The DisplayPort connector supports 1, 2, or 4 data pairs in a Main Link that also carries clock and optional audio signals, each with a symbol rate of 1.62 or 2.7 Gbit/s. The video signal path supports 6 to 16 bits per color channel. A bi-directional auxiliary channel (at a constant 1 Mbit/s) carries management and device control data for the Main Link using VESA EDID and VESA MCCS standards. The video signal is not compatible with DVI or HDMI, but a DisplayPort connector can pass these signals through.
