Integrated Graphics Subsystem

6.1Introduction

This chapter describes the graphics subsystem that is integrated into the Q45 GMCH component. This graphics subsystem employs the use of system memory to provide efficient, economical 2D and 3D performance.

All systems provide dual-monitor support in the standard configuration. The SFF and CMT systems include two PCIe graphics slots for upgrading the graphics controller by:

■Installing a PCIe x16 graphics card in the PCIe x16 graphics slot, which disables the integrated graphics controller

■Installing a PCIe x4 graphics card in the PCIe x4 slot (x16 connector), in which the integrated graphics controller can be re-enabled through the BIOS settings

This chapter covers the following subjects:

■Functional description (6.2)

■Display Modes (6.3)

■Upgrading (6.4)

■Monitor connectors (6.5)
