This feature supports video output only; audio is not output to the external monitor.
Configuring an external monitor
Prior to previewing on an external monitor, you’ll need to configure your system to use this feature. From the Options menu,
choose Preferences and then click the Preview Device tab to configure an external monitor. Your video will be sent to this device
when you click the Preview on External Monitor button (
) in the Video Preview window. For more information, see Setting
preferences on page 415.
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.
Preview requirements:
• 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 Graphics Card device on a computer with a single monitor. When you enable the external
monitor, the video preview will fill your screen.
• 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.
•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).
Follow the steps below to set up your preview:
1. Use the Preview Device tab in the Preferences dialog to configure the display you want to use as a video preview monitor. For
more information, see Preview Device tab on page 419.
2. Select the Preview on External Monitor button ( ) in the Video Preview window.
Notes:
• 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.
• Vegas Pro software allows you to use one external video device at a time. The external monitor display will be unavailable during
video capture.
• 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.
