First to answer the question, I have used the built in Display port to VGA and last year we used a second projector and used a Matrox dual-head-2-go.  

While we are on this I would like to hijack this thread, I have been trying to research the best way to get multiple video outputs.  I would prefer to run two individual outputs out of an 2009 iMac.  I have an older Matrox VGA dual-head-2-go and I am having a harder time getting drivers to work.  I would prefer to edge blend two surfaces anyway.  Do you have any suggestions as some good economical devices (brands and models) that will work well.  I have borrowed and tried a variety of cheaper usb to video adaptors with varying success.  My current projectors don't have HDMI in but my next pair probably will.  

Sorry for the thread hijack.
