We are currently piloting a test group of Surface Pro 3 units and will order the docking station once they are available. From what I've read, the docking station (and the tablet) only have a single miniDisplayPort for hooking up an external monitor. How can I attach two external displays to the docking station? Even if it is an option to use both the miniDisplayPort on the docking station AND the miniDisplayPort on the tablet, this is not an acceptable option for my staff. I need a solution that is fairly inexpensive that uses the docking station's miniDisplayPort to two external monitors. Thanks.
