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.

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. 2-10 www.hp.com Technical Reference Guide

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.

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.
