XPS 12 2in1 USB 3 dock Video disappears periodically

This XPS (DELL XPS 12 2 in 1 Ultra touch) was recently upgraded to Windows 10 (from 8). After that I purchased a USB 3 Docking Station (HDMI and DVI, few USB ports) that uses the DisplayLink drivers. I have connected two identical ViewSonic monitors one using HDMI and the other DVI.

Upon first boot both display fine. after few minutes (sometime immediately) the two monitors go blank while the other USB devices continue to operate normally. The display might comeback but in not all the cases. I disconnect the power to the USB docking station and reconnect for the monitors to display anything.  This happens all day. Sometimes it gets stable.

For testing, I have connected another Laptop Vostro V131 to the docking station today. The displays are functioning 100% with no hiccups.

Any help?
