Problem with new Thunderbolt 3 Dock (Plugable TBT3-UDV).
[NOTE THAT THE DEVICE IS NOT SELECTABLE WHEN CREATING THIS REPORT]
OS: Windows 10 (Version 1709; Build 16299.125)
PC: Dell XPS 13 9350
When connected to the Plugable TBT3-UDV dock, the secondary display on external monitor after variable times of normal use (few minutes up to an hour) suddenly “scrolls” left and right spontaneously for 1-2 seconds and then settles with the desktop wrapped around from the right edge to the left and the left edge of the desktop ending up in the middle of the external display. Display continues to “shake” right and left quickly. This began today. Main display on laptop working normally. I am using “Extend these displays” in Windows settings to extend the desktop to the second monitor (no different than before).
I have updated my display driver, bios, and Thunderbolt software/driver all to the most recent from Dell. I have reinstalled from scratch the most recent display driver (using safe mode).
External display (Dell U2717D) is connected via DP-HDMI adapter provided with the dock and to monitor’s HDMI input via a quality HDMI cable. I previously tried DP->DP cable (quality one) which resulted in flickering.
All other devices connected to the dock work normally (USB external drive x2, audio, USB card reader device, ethernet).
Interestingly, the 2nd display will reset to normal functioning if I go into Windows display settings, change multiple display to display 1 only (in effect, stop sending display to 2nd monitor) and then turn it back to “extend desktop”. But the problem will repeat itself within minutes.
