I just unpacked my docking station for the SP3 and the mini displayport doesn't work. I have 2 monitors with displayport to mini displayport cables. One plugged into the Surface, one into the dock, just like Microsoft has shown in their blog posts. The one out of the Surface works, is detected by Windows just fine. The dock one is not recognized by Windows and I can't force it to. If I swap the cables to the opposite ports the broken monitor works and the other doesn't. That rules out the cable and monitor, all of those are working. Does anyone else have a malfunctioning dock?
