If multiple video cards are installed on the system, dual head
monitor support is available and is configured via the Dual head tab, as shown in Figure
32-3.
To enable use of dual head, check the Use
dual head checkbox.
To configure the second monitor type or any of its settings,
click the corresponding Configure
button.
For the Desktop layout option,
selecting Spanning Desktops allows both
monitors to use an enlarged usable workspace. Selecting Individual Desktops creates a mirrored workspace
effect, similar to laptops.
