intensity pro to laptop?

I'm trying to do some work on Color using a proper monitor and I confirm that it does not output video.
So far what I've read, one needs to pass by Blackmagic intensity pro or others such as matrox (though more $). The problem for me is that I have a Powerbook G4 and a Macbook pro - both laptops. Does anyone have an idea about how to make blackmagic intensity pro work on a laptop without buying a +$700 side thing? I would be most appreciative!
