Embedded Display Port (Edp) - Congatec conga-IA3 User Manual

Embedded Display Port (eDP)

The conga-IA3 provides eDP interface on connector X28 - a standard 40 pin DisplayPort connector. The eDP signals are sourced from the SoC's
eDP stream via a multiplexer. Depending on the BIOS setup, the multiplexer routes the eDP stream either directly to the eDP connector X28
on the bottom side of the SBC or to the LVDS connector X32 (top side) via an eDP to LVDS bridge. The multiplexer is by default configured in
the BIOS setup to route the eDP signals to the eDP to LVDS bridge.
To route eDP signals to connector X28, change the default BIOS setup.
