Multiple Display Adapter Installation
Applies To: Windows Server 2008 R2
Windows Vista and Windows Server 2008 require that when multiple graphics adapters are used in a computer, they must be of the same display driver model type: either Windows Display Driver Model (WDDM), or Windows XP Display Driver Model (XPDM). If multiple WDDM graphics adapters are present, then they must all use the same WDDM driver. If the either requirement is not met, then Windows uses the adapter that was used to start the computer, and disables any others.
For more information about using specific features of your graphics adapter, visit the manufacturer's Web site. For more information about using multiple graphics adapters and multiple monitors, see "MultiMonitor Support and Windows Vista" at http://go.microsoft.com/fwlink/?LinkId=76622 on the Microsoft Web site.
|At least one display adapter on the system has been disabled because its driver is not compatible with the driver for the VGA adapter.|
