Hardware Reference
In-Depth Information
Install the graphic card or chipset vendor's latest drivers instead of using the drivers in-
cluded with Microsoft Windows. Standard Microsoft drivers often don't include 3D or
other advanced dialog boxes.
Can't enable multiple monitors.
Solution
If you are using a multihead graphics card, make sure the additional monitors have been
enabled in the manufacturer's driver. This might require you to open the Advanced set-
tingsforyourdriver.(Makesureyouareusingthelatestone.)Ifyouareusingtwoormore
video cards in an SLI (NVIDIA), CrossFire (ATI) or CrossFireX (AMD) configuration,
you must normally disable this configuration before you can enable additional monitors.
If you are using multiple video cards in separate slots, check the BIOS Setup configura-
tion for the primary adapter.
Can't enable SLI operation.
Solution
Make sure the MIO (SLI bridge) device is properly installed between your video cards
(refer to
Figure 12.16
). If you are not using identical video cards, you must use NVIDIA
ForceWare v81.85 or new drivers to enable SLI operation. Make sure both cards use the
same GPU family. Make sure SLI operation is enabled in the ForceWare driver.
Can't enable CrossFire or CrossFireX operation.
Solution
If you are using first-generation CrossFire cards, make sure you have paired up a
CrossFire Edition and standard Radeon card from the same GPU family. Also, make sure
you have properly connected the CrossFire Edition and standard card.
Ifyouuselater-model cards that useaCrossFire orCrossFireX bridge interconnect, make
sure the interconnect is properly attached to both cards. Make sure you are using pairs of
cards with the same GPU.
Update the ATI CATALYST display drivers to the latest production version. Be sure you
have enabled CrossFire or CrossFireX in your display driver.
Can't enable Aero 3D desktop in Windows Vista or Windows 7.
Solution
Make sure your video card or integrated video is running a WDDM (Windows driver dis-
playmodel)driverandsupportsDirectX9.0orlater.Updatethedriverifthehardwarecan
support Aero. Update the card if the card does not have WDDM drivers available.
