Embedded Display Port (eDP)
The conga-IC170 provides eDP interface on connector X20 - a standard 40-pin DisplayPort connector. The eDP signals are sourced from
incoming eDP stream via a multiplexer. The multiplexer routes the eDP signals to LVDS connector X25 (via an eDP to LVDS bridge) by default.
To route the eDP signals to eDP connector X20, change the ‘Active LFP Configuration” in the BIOS setup menu to ‘eDP’.
The eDP interface is found on the bottom side of the SBC.
