Do you have a second DVI output connector on your available graphics card? If so, either attach a 1920 x 1080 or 1920 x 1200 monitor to it and in the upper right hand corner of the Program Monitor widow select the tiny menu and at the bottom select Playback Settings and then your second monitor. If you want to use a HDTV then an adapter from the DVI connctor will convert it to an audio-less HDMI signal.

Yes I do, and now that I know that DVI can be converted to HDMI, I think I'm all set. Thank you!
Just to follow up.
My video card - the Quadro FX 570 - does not support 60 hz refresh rate at 1920x1080, only 30 hz. My Viewsonic HDTV requires 60 hz at that resolution, and can't do lower resolution without cutting off the image (no matter which "zoom" setting I choose). I think I'll buy a second computer monitor and just stretch the workspace such that the video image fills one monitor and the controls fill the other monitor.
It would be easier and better to dump that video card. The lower end Quadro's are basically garbage for editing. I would look at one of the lower 400 series cards like the 450.
