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.
