Integrated Graphics Subsystem

6.1 Introduction

This chapter describes the graphics subsystem that includes the integrated graphics controller of

the Intel Celeron, Pentium or Core i3/i5/i7processor. The integrated 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. These systems can be

upgraded by installing a PCIe x16 graphics card in the PCIe x16 graphics slot, which disables the

integrated graphics controller

This chapter covers the following subjects:

■ Functional description (6.2)

■ Upgrading (6.3)

■ Monitor connectors (6.4)

6.2 Functional Description

The integrated HD Graphics controller (hereafter referred to as an internal graphics controller or

IGC) featured in the processors supported by these systems operates off the internal PCIe x16

bus of the processor and, through the Flexible Display Interface (FDI) and the PCH-DO

component, can drive an external analog multi-scan monitor and/or a DisplayPort-compatible

digital monitor. The IGC includes a memory management feature that allocates portions of

system memory for use as the frame buffer and for storing textures and 3D effects.
