23 Facts About DisplayPort

DisplayPort is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA).

DisplayPort was designed to replace VGA, FPD-Link, and Digital Visual Interface.

DisplayPort can be used to transmit audio and video simultaneously, although each can be transmitted without the other.

However, dual-mode DisplayPort ports are designed to transmit a single-link DVI or HDMI protocol across the interface through the use of an external passive adapter, enabling compatibility mode and converting the signal from 3.

Unlike DVI and HDMI, which vary their transmission speed to the exact rate required for the specific video format, DisplayPort only operates at a few specific speeds; any excess bits in the transmission are filled with "stuffing symbols".
