It's very easy. Just detach and drag the preview window over to the second monitor. Resize as necessary. Keep in mind that the larger you make it, the slower the frame rate of the preview will be.
hi and thnx. but i don't mean any workarounds. i mean a real preview on a control-tv.
for example with Matrox 2500 u can do it without any workarounds. (i don't know if Matrox works with VV3)
