3.11.2 Dual Video
The BIOS supports single- and dual-video modes. The dual-video mode is enabled by default.
In single mode, the onboard video controller is disabled when an add-in video card is
detected.
In dual mode (enable “Dual Monitor Video” in BIOS setup), the onboard video controller
is enabled and is the primary video device. The add-in video card is allocated resources
and considered the secondary video device.
The BIOS Setup utility provides options on Advanced | PCI Configuration Screen to
configure the feature as follows:
Onboard Video
Enabled (default)
Disabled
Dual Monitor Video
Enabled Shaded if onboard video is set to "Disabled"
Disabled (Default)
