1.6.1.5
Advanced Digital Display (ADD2/MEC/ADD2+) Card
Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
400 MHz pixel clock to the PCI Express x16 connector.
When an ADD2/MEC/ADD2+
card is detected, the Intel GMA 4500 graphics controller is enabled and the PCI
Express x16 connector is configured for SDVO mode.
SDVO mode enables the SDVO
ports to be accessed by the ADD2/MEC/ADD2+ card.
An ADD2/MEC/ADD2+ card can
either be configured to support simultaneous display or can be configured to support
dual independent display as an extended desktop configuration with different color
depths and resolutions with DVI analog output only.
ADD2/MEC/ADD2+ cards can be
designed to support the following configurations:
•
Low Voltage Differential Signaling (LVDS)
•
Single device operating in dual channel mode
•
HDTV output
•
HDMI support (when used with the HD Audio Link header)
