Introduced around the same time as the competing connectors for the Digital Visual Interface (DVI, 1999) and VESA's own Digital Flat Panel (DFP, 1999), it was marketed as a replacement for the VESA Enhanced Video Connector (EVC, 1994).
[1]: §9.4 All P&D connectors are required to carry single-link TMDS digital video signal (max 160 MHz), and support VESA Display Data Channel version 2 at a minimum.
[1]: §9 The nominal impedance of each signal line is 75 Ω and each channel must be capable of carrying a bandwidth of at least 2.4 GHz.
[1]: §7.10.1.9 The type designation for the analogue video signals designates the voltage values of the signals only, including the Type 4 (VESA) analog DC protocol introduced with EVC:[1]: §4.5.2.1 The P&D connector supports optional charging power at 18–20 VDC and up to 1.5 A.
The USB connector is intended for passing mouse movements from a projector's wireless remote to the computer's presentation software and for firmware upgrades.
