ZBook 17G3 with TB3 Dock will not display on Second Monitor and no USB Chained Devices

ZBook 17G3 & 200W TB3 Dock
Microsoft Windows 8.1 (64-bit)

Absolutely frustrated beyond belief.


Have a high end workstation and dock and cannot function worth anything.


The first issue is that the unit recognizes the second external monitor (indentified in the display settings)  but will not display. Once in a while the monitor blinks on but then goes back to sleep. Both external monitors are connected via DisplayPort. Both are identical EliteDisplay 221i units. Switching the connections on the dock moves the issue from one monitor to the other. Driver issue or hardware issue? What do I do to get both monitors functional?


The second issue is that I have a seven (7) port USB hub connected to one of the USB ports on the dock. The dock will only recognize the first device connected to the hub. All of my devices are recognized individually when plugged into the hub but no more than one at a time. How do I get access to all of my devices?


I cannot believe that such expensive hardware which is supposed to be state of the art (latest technology) can be so unfunctional and such a step backwards.
