5.3 Using Multiple Monitors
The multiple monitor features available with Windows Vista and Windows XP
allow multiple video cards to be active with each one displaying a different area
of the entire desktop. S3 Graphics discrete GPUs are Dual Head devices. This
means each device has two graphics engines, each of which is capable of
providing independent display output. Windows Vista and Windows XP support
the use of a single adapter to drive a multiple monitor configuration.
When the Windows operating system is in SingleView, there is a single view of
the desktop image displayed, regardless of the number of monitors enabled. This
single view of the desktop is
sometimes referred to as the
Primary View. There may be
one (Primary Monitor or Main
Monitor) or more display output
devices (Multiple Monitors)
associated with this single
Primary View. These monitors
are said to be “child devices” of
the Primary View and provide a
duplicate view, or clone view of
the Primary View.
When in SingleView, the
Primary View owns all of the
child devices, and the (inactive)
Secondary View owns none.
When you select Extend the
desktop onto this monitor,
DualView mode is enabled. The
Windows desktop image is
divided into two parts or views,
the Primary View and the
Secondary View. The Display
Settings window shows you
which output devices are
associated with each desktop
view. Windows This is my main
monitor (XP: Use this device…)
option allows you to specify
which device you wish to display
the Primary View.
