Read a numbered full-size DisplayPort source pinout with Main Link, AUX, HPD and DP_PWR explained. Distinguish connector numbering from cable continuity.
Source receptacle mating face. Beckhoff figure 5 rotated 90° clockwise: chamfer lower left, odd 19…1 above, even 20…2 below. Not a sink or cable rear view. DP_PWR is not a general cable power bridge.

Numbering follows the source-side full-size DisplayPort example in the Beckhoff C6032 manual. This table is not a mating-face drawing, a Mini DisplayPort pinout, or a cable end-to-end continuity map. Match the equipment drawing before use; receiver lane labels may differ.
The table identifies all 20 numbered contacts of a full-size source connector using the Beckhoff C6032 connector example. It is suitable for reading documentation, not for guessing which contact is on the left when viewing an unknown plug.
Separate Main Link video transport, AUX configuration and HPD detection when reading a DisplayPort design.
Main Link uses differential lanes for audio/video; AUX is the bidirectional control channel; HPD indicates connection and interrupts. Contacts 13 and 14 are configuration contacts whose interpretation depends on the operating mode. Pin 20 is DP_PWR, not another video lane.
The page is structured as a practical reference: start with the visible table, diagram and labels, then compare them with the exact connector, device, enclosure or symbol set in front of you.
Use the listed sources to confirm revision, naming and application context. Similar labels can hide different electrical limits, pin functions or test conditions, so the page should be treated as a guided reference rather than a universal standard text.
In this source-side numbering, AUX+ is 15, its return is 16, AUX− is 17, HPD is 18, power return is 19 and DP_PWR is 20. This sequence is a lookup list, not a physical face drawing or an instruction to connect every same-numbered pin across a cable.
Ordinary passive DisplayPort-to-DisplayPort cables must not join the two devices’ DP_PWR supplies through pin 20. Adapter and active-cable arrangements require their own compliant design. Use a suitable certified cable rather than improvising a modification.
No. This page’s numbered table is explicitly full-size source DisplayPort. Mini DisplayPort and USB-C require separate connector drawings.
No. Plug/receptacle and mating/solder-side views must be identified. A correct signal table can still be mirrored incorrectly when used without that context.
