Supported video modes for the board
1.7.1.4
Digital Video Interface (DVI)
The DVI port supports only DVI-D displays. If a DVI-I display is connected, only the
digital signal will be displayed. The maximum supported resolution is 1600 x 1200 at
60 Hz. The DVI port is compliant with the DVI 1.0 specification.
Depending on the type of add-in card installed in the PCI Express x16 connector, the
DVI port will behave as described in Table 5.

PCI Express x4, x8, or 16 add-in card installed
ADD2 or MEC card installed
1.7.1.5
Advanced Digital Display (ADD2/MEC) Card Support
The GMCH routes two multiplexed SDVO ports that are each capable of driving up to a
200 MHz pixel clock to the PCI Express x16 connector. The SDVO ports can be paired
for a dual channel configuration to support up to a 400 MHz pixel clock. When an
ADD2/MEC card is detected, the Intel GMA 3000 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 card. An ADD2/MEC card can either be
configured to support simultaneous display with the primary VGA display or can be
configured to support dual independent display as an extended desktop configuration
with different color depths and resolutions. ADD2/MEC cards can be designed to
support the following configurations:
•
TV-Out (composite video)
•
Transition Minimized Differential Signaling (TMDS) for DVI 1.0
•
Low Voltage Differential Signaling (LVDS)
•
Single device operating in dual channel mode
•
VGA output
•
HDTV output
•
HDMI/UDI support (when used with the HD Audio Link)
