I'm just an MVP not an engineer...Engineers are going to engage at the official Surface Support Forums (http://answers.microsoft.com/en-us/surface/forum/).jnjroach, can you tell me if MS engineers ever respond to these forums? If you ARE that person, I apologize. If you are, can you tell us if the Dock's Mini DP and the Surface Book's Mini DP are somehow different? It's the only explanation from these posts. Maybe HDCP is treated differently? If not this, than what else might be different?
We appreciate the help!
Much of what we're seeing is DP 1.2 hasn't been consistently implemented by Monitor Makers and Cable Makers....
