The prescribed method to get external preview from Vegas is via an OHCI compliant IEEE 1394, aka 'Firewire' card. (Note: not all firewire cards are OHCI compliant.)

The connection is as follows:

OHCI Firewire port > D/A converter > TV

A camcorder with pass-through is commonly used for the D/A, or a dedicated D/A converter can be used. Connection from D/A to TV is typically done using s-video if that option is available.

Only the video signal is sent to external preview, the audio portion is played through the computer's sound card.

OK BUT WILL THE EXTERNAL MONITOR WILL LET ME SEE ALL TRASITIONS AND VIDEO EFFECTS IN REAL TIME . AND WHAT VIDEO CARD SHOUD I USE FOR MAXIMAL PERFORMANCE .

Your video card has nothing to do with performance of how close you get to "real time" previewing on some external monitor IF you feeding it through a firewire out through some type of digital to analog black box or if your camera does it.

How close you get to seeing "real time" previews depends on:

1. the raw horsepower of your CPU
2. the complexity of what you're attempting to preview.
3. settings of the Preview window

Real time is one of those terms that can take on different meaning depending on what context it is used in. For example if you take some footage shot with a digital camera, render it out as DV AVI after to edit it, then reload on the timeline, then you'll get "real time" in that if you picked a NTSC DV template you'll see 29.97 frames a second.

HOWEVER, if you're still working on the project and want to see the effects of your work as you apply transitions, edit, etc., then "real time" will be at a frame rate something less than your project's set frame rate. How much of a drop off depends on the complexity of what you're attempting to preview PLUS the settings you set the preview window to. So dropping from BEST to GOOD should get you closer to "real time" preview. If still jerky, keep dropping. I frequently go down to DRAFT quality. For previewing it should be acceptable for most situations while in previewing mode.
