I have a 2407 on order and will likely order a MBP in the coming months, but I also have another 19" display I'd like to use. Could the MBP power them both simultaneously? I've heard about Matrox Triplehead2Go product, but I'm not sure if it's applicable to the MBP since it only has 1 output. Would Matrox or anyone else offer a better suited application for my needs?
