Summary: The Matrox DualHead2Go Digital SE allows you to extend your desktop for hardware that has limited capabilities. This device only takes input from a DisplayPort and most hardware that features a “professional” graphics port can easily drive three monitors. I’ve seen some laptops that do have a DisplayPort plug but only feature Intel HD integrated graphics, which in many cases will not drive more than two monitors.
Excerpt: Matrox essentially invented the idea of driving multiple monitors from one computer. The ability to spread your workload across multiple screens has long been an excellent aid to productivity.
