I would like to run dual monitors with my Macbook. I know that I have to get the mini DVI to VGA/DVI/Video adapter but I was wondering if going out S Video from the mini DVI to Video adapter will allow me to be able to drag a window from my laptop screen to my external display. Im looking for this capability because Im currently already using the VGA port on my monitor and it has an S Video port so it would be more convenient to use the S Video port. I need the second screen though because I run Logic for my audio mixing and the 13" screen is a little cramped for everything. So I would like to put some things on one screen and the others on the other. So my question is if the S Video adapter will allow me to have the same capabilities as the VGA/DVI adapter. Thanks.
