- VESA Plug and Display
VESA Plug and Display (P&D) is a video connector for digital monitors, such as
flat panel display s andvideo projector s, ratified by VESA. It was introduced around the same time as DFP, marketed as a replacement ofVESA Enhanced Video Connector and an extension of DVI.The P&D connector shares the pin layout of VESA EVC, but the pins assigned for carrying analogue audio and video in signals are reused to carry digital video signals.
ignals
A basic P&D line carries single-link
TMDS digital video signal (max 160MHz), and supports VESADisplay Data Channel version 2.Analogue video signals, if supported, must be capable of carrying at least 150MHz bandwidth.
USB version is not specified, but if supported, it would have been intended for contemporary USB standards.Firewire , if supported, must be compliant to IEEE 1394-1995 specification.Connectors
Although the pin layout comes from VESA EVC, the connector shell is slightly different. P&D-A/D is compatible with EVC device (except for the missing VESA EVC features), P&D-D is not.
In addition to the regular P&D connector, the standard also specifies a 40-pin
microribbon connector, which is only defined when making digital video connection.Articles such as those from
The Register sometimes mistake the P&D port as an alternative form of theApple Display Connector [http://www.theregister.com/2000/09/27/what_the_hell_is_apples/] , but ADC carries higher current, has different pin layout, and does not support FireWire.Alternative names
