GRL DisplayPort AUX Protocol Decode Software (GRL-DPAUX-DEC)

Debug DisplayPort 1.2 & eDP AUX transactions in Real-Time

Overview

  • Get detailed insight into DisplayPort AUX transactions.
  • Correlate between DisplayPort AUX Physical layer and Protocol Layer.
  • Easily interpret AUX traffic register values and timings.

Description

The DisplayPort Auxiliary (AUX) channel is a bi-directional, half-duplex channel that carries device management and control data for the DisplayPort main link, such as VESA EDID, MCCS, and DPMS standards. An oscilloscope with GRL-DP-AUX-DEC DisplayPort AUX protocol decode software connected between the Source and Sink device captures DisplayPort AUX traffic and timings. All AUX transactions - like DPCD reads and writes, and EDID reads - can be clearly viewed and analyzed, along with the physical layer signal captures.

GRL-DP-AUX-DEC analyzes all native DisplayPort and I2C traffic and displays the complete associated register details. The ability to analyze these detailed transactions between Source and Sink plays a major role in quickly debugging DisplayPort and eDP interoperability problems.
