I have two Surface Pro 3 devices (one on Win 10 and one on Win 8.1). Each Surface has the new Docking station plugged into a large display monitor.
When the Win 8.1 SP3 is plugged in the device charges but does not detect the display. However, if I plug the Win 10 device into the same dock the dock is detected and the extended display is activated. Once the docking station has been activated it can be plugged into the Win 8.1 device and it works perfectly.
I'm forced to plug in the Win 10 device into docking station once, then the Win 8.1 device will work for the day.
Is there some fix for this?
