Integrated Graphics Subsystem
6.3 Display Modes
The IGC supports most standard display modes for 2D video displays up to and including 2048 x
1536 @ 85 Hz , and 3D display modes up to 1600 x 1200 @ 85 Hz. The highest resolution
available will be determined by the following factors:
■ Memory speed and amount
■ Single or dual channel memory
■ Number and type of monitors
✎
The IGC is designed for optimum performance with multi-sync analog monitors.
Digital displays may not provide an image as high in quality, depending on resolution.
6.4 Upgrading Graphics
The IGC of SFF, ST, MT, and CMT systems is upgradeable by installing an Advanced Digital
Display 2 (ADD2) or a graphics controller card into the PCI Express x16 graphics slot. All
systems can be upgraded by installing a PCI card in the PCI 2.3 slot (assuming no riser cards are
installed). Depending on accessory, upgrading through the PCI Express x16 slot can provide
digital monitor support and/or dual-monitor support allowing display-cloning or extended
desktop functionality. Software drivers may need to be downloaded for specific cards.
✎
Two SDVO channels are provided by the IGC for supporting two digital displays. Existing option
cards and drivers support one CRT and digital display. Dual digital display support may be
possible with future cards and drivers.
The upgrade procedure is as follows:
1. Shut down the system through the operating system.
2. Unplug the power cord from the rear of the system unit.
3. Remove the chassis cover.
4. Install the graphics card into the PCI Express x16 graphics or PCI 2.3 slot.
5. Replace the chassis cover.
6. Reconnect the power cord to the system unit.
7. Power up the system unit.
The BIOS will detect the presence of the PCI card and disable the IGC of the 82915G GMCH.
✎
.If a PCI 2.3 graphics card is installed, the IGC can be re-enabled through the Setup Utility (F10)
but may require driver installation. If a PCI-E graphics controller card is installed, the IGC
cannot be enabled.
