usb 3000 second monitor blank

Have Samsung NP-700Z5A-S04US PC, windows 7-64 bit o/s
Plugable USB 3.0 docking station.
Monitor connected to Plugable via DVI-D cable, when set to mirror primary display, only mouse trails appear. When set as extended display, only mouse trails appear.
We just returned a USB2 Plugable dock to upgrade to the 3.0 USB version with same results. I’ve also downloaded latest AMD HD 6750 drivers from Samsung for internal display driver - no change.
