System Overview

2.3.9 Graphics Subsystem

These systems use the Q45 GMCH component, which includes an integrated graphics controller that can drive both an external VGA monitor and a DisplayPort digital display. The controller implements Dynamic Video Memory Technology (DVMT 3.0) for video memory. Table 2-5 lists the key features of the integrated graphics subsystem.

Outputs

1 VGA, 1 DisplayPort 1.1 [see text]

All systems include a legacy VGA connector and a DisplayPort connector and support dual monitor operation. The DisplayPort includes a multimode feature that allows a DVI or VGA adapter to be connected to the DisplayPort.

These systems also include two PCIe graphics slots (one x16, one x4/x16 connector) to ensure full graphics upgrade capabilities.

2.3.10 Audio Subsystem

These systems use the integrated High Definition audio controller of the chipset and the ADI AD1884A High Definition audio codec. HD audio provides enhanced audio performance with higher sampling rates, refined signal interfaces, and audio processors with increased signal-to-noise ratio. The audio line input jack can be re-configured as a microphone input, and multi-streaming is supported. These systems include a 1.5-watt output amplifier driving an internal speaker, which can be muted with the F10 BIOS control. All models include front panel-accessible stereo microphone input and headphone output audio jacks.
