LVDS

The conga-IA3 offers LVDS interface on connector X32 - a standard 40 pin LVDS connector. The LVDS 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 or to
the LVDS connector X32 via an eDP to LVDS bridge. The multiplexer is configured in the BIOS setup by default to route the eDP signals to the
eDP to LVDS bridge. The eDP to LVDS bridge processes and converts the eDP stream to LVDS format.
The LVDS interface is found on the top side of the SBC and supports 24 bit single channel, selectable backlight voltage, VESA color mappings,
automatic panel detection and resolution up to 1920x1200 in dual LVDS mode.
