4.4 Display Connectors
The 986LCD-M 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 SDVO port available on the PCI
Express connector.
