Connectors
The 886LCD board family provides onboard two basic types of interfaces to a display: Analog CRT interface
and a digital interface typically used with flat panels. The digital interface to flat panels can be achieved
through the onboard LVDS dual channel interface and/or the DVO port available on the AGP connector.
