Connectors
The 786LCD board family provides onboard two basic types of interfaces to a display: Analog CRT interface
and a digital interface available as either LVDS dual channel interface or DVI (analogue/ digital) depending
on the board configuration. Further an onboard AGP slot supports AGP 2.0 including 4X AGP data transfers.
DVO is not supported in the AGP connector.
