Product Description

and graphics drivers allocate additional system memory to the graphics buffer as

needed for performing graphics functions.

NOTE

The use of DVMT requires operating system driver support.

1.7.1.3

Configuration Modes

A list of supported modes for the Intel GMA 3000 graphics controller is available as a

downloadable document.

For information about

Refer to

Supported video modes for the board

Section 1.2, page 17

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 following specifications:

•

DVI 1.0

•

HDCP rev 1.1 down-stream compliant (when applicable)

Depending on the type of add-in card installed in the PCI Express x16 connector, the

DVI port will behave as described in Table 6.

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)
