Introduction
SurroundView is the ATI technology that provides multi-graphics controller display capability for both
the ATI PCIe-based graphics card and the ATI integrated graphics processor (IGP). This document
outlines sample display configurations with SurroundView enabled on the Radeon Xpress 300 ATI
chipset incorporated into the HP dc5750 Business PC. Enabling SurroundView does not impact
display modes (resolution and color depth) or performance. The display mode of each output is
controlled independently by the graphics controller connected to it. The modes listed in the table
below vary for each system configuration and are dependent on monitor capabilities. These values
are the absolute maximum, assuming memory bandwidth is not a limiting factor.
Radeon Xpress 300 Display Configuration
Figure 1. Radeon Xpress 300 Display Configuration
Up to four displays can be connected to a Radeon Xpress 300 system with a single PCIe graphics
card and SurroundView enabled. More than four displays are possible using additional PCI graphics
controllers. The Radeon Xpress 300 supports a Digital Video Interface (DVI) connected to a DVI
monitor, in addition to analog output to a VGA monitor or TV.

A PCI Card can be
installed in any
configuration. This is a
standard multi-display
feature supported by the
Microsoft Operating
System.
Notes:
1. When using a non-ATI PCI Express (PCIe) graphics card, SurroundView is not supported. The integrated graphics processor (IGP) is
automatically disabled, and the system memory allocated to the IGP is freed for other use.
2. When installing an ATI PCIe graphics card, SurroundView is disabled by default. Enabling SurroundView in the BIOS (F10 Setup) enables the
integrated UMA graphics controller, which in turn makes available up to two additional graphics outputs. When enabling the integrated UMA
graphics controller, system memory will be reallocated.
•The amount of memory allocated to internal graphics is determined in the BIOS (F10 Setup) setting
Advanced/Device Options/Integrated Graphics Memory Size. The default value “Automatic”
means that the Graphics memory is 32MB for a 256MB system, 64MB for a 512MB system, or
128MB for systems with more than 512MB installed. Alternatively, the user can specify the memory
size to use from 32MB, 64MB, 128MB, or 256MB.
•The option to disable the internal graphics will appear in the BIOS (F10 Setup) menu at
Advanced/Device Options/Integrated Video whenever a PCI graphics card is installed. Disabling
internal graphics frees up the allocated UMA graphics memory when a PCI graphics card is the
only adapter required.
•When a PCI graphics card is used in combination with the integrated graphics processor and/or a
PCIe graphics card, it cannot be set as primary. By default it is configured as a secondary
controller. If, instead, the PCI graphics card is the only enabled controller in the system, by
necessity it is the primary controller.
•Potentially, a non-ATI-branded PCIe graphics card could be installed, one that contains an ATI
chipset and uses ATI-based software drivers, but does not support SurroundView. This may be
caused by an older card and older driver source code. You may not be able to use SurroundView
with all PCIe card combinations. All ATI-branded PCIe cards support SurroundView. Consult ATI
Technologies Inc. for a complete listing of ATI cards.
