System information
Notes:
n  Vegas Pro allows you to use one external  video device at a time. The external monitor display 
will be unavailable  during video capture.
n  When using  an external video monitor, you need to enable external-monitor preview  each time 
you start Vegas Pro. This  change was made to prevent the possibility of hiding the main Vegas 
Pro window behind the secondary display  when monitors are improperly configured.
Previewing Video on a Secondary Windows Display
If your Windows desktop is extended across multiple displays, you can  use one of those displays to preview 
the timeline with no A/V synchronization  drift — perfect for   ADR and Foley work.
If you intend to deliver your project in an interlaced format,  previewing on a computer monitor is not 
a substitute for previewing on  an interlaced broadcast monitor.
Preview requirements:
n  A multiple-output  graphics card that supports 3D acceleration (or multiple graphics cards:  you 
could install AGP and PCI video  cards in your system, for example).
You can also use the Windows Secondary Display device on a computer  with a single monitor. 
When you enable the external monitor, the video  preview will fill your screen.
n  A CRT, LCD, or projector connected to your computer's secondary video output.
If you have a video card with DVI outputs, you can use a DVI-to-HDMI  converter to connect to an 
HDMI monitor.
n  The Extend my Windows desktop  onto this monitor check box must be selected on the Settings tab  
of the Display Properties dialog (Start > Settings > Control Panel  > Display).
