I RECENTLY BOUGHT UD-3900 DOCKING STATION FROM AMAZON AND BEFORE I CONNECT TO MY LENOVO THINKPAD YOGA S1 ULTRABOOK, I DOWNLOADED THE DRIVERS SENT BY PLUGABLE AND INSTALLAED THE SAME. EVERYTHING IT SEEMS WORKED FOR FIRST FEW MINUTES AND SUDDENLY DISPLAY WENT OFF AND I TRIED CONNECTING TO MULTIPLE DISPLAYS / MONITORS THRU DVI AND HDMI CABLES, BUT NO USE. IS THE SHIPPED DEVICE UD-3900 SENT BY AMAZON DEFECTIVE ? I NEED SOME HELP AND SUPPORT HERE. I TRIED REBOOTING THE SYTEMS MULTIPLE TIMES AND TRIED POWER OFF THE UD-3900 USB 3.0 ALSO MULTIPLE TIMES. BUT NO USE. ANY INPUTS IN THIS MATTER WILL DEFINATELY HELP ME, BEFORE I RETURN THE UNIT BACK. THANKS. ATHMARAM
