Windows–Using the Graphics to SDI Control Panel
Using SDI Under Dualview
In the default configuration, the SDI output is a clone of the display output. The NVIDIA
Quadro FX 4500 SDI graphics card also supports Dualview mode, where the desktop
extends across two monitors.

About Dualview Mode

Under Dualview mode, you can define one large desktop that extends from the display to
the SDI output. This lets you move windows between the SDI output and the graphics
(DVI) display part of the extended desktop.
With applications that use video overlay or Microsoft VMR, you can also display the
video full-screen on the SDI output.

The display and the SDI output do not need to be the same resolution and refresh rate.
