Occasionally, my Plugable UD-3900 will lose connection with my Lenovo ThinkPad E15. I have 2 Sceptre E24 monitors attached to the Docking Station (1- via an HDMI to HMDI cable and 1 - via an HMDI to DVI cable).
I use to have the Ethernet plugged in to the Docking Station as well. I now have the Ethernet cable plugged directly into my laptop, due to the dropping of connection between my Docking Station and Laptop reeked havoc on my network connection. I prefer to have all of my devices attached to the Docking Station so I only need to unplug one USB cable and when I need to take my laptop with me.
I have updated all my drivers, Bios, Windows 10 updates.
The blanking of my monitors as well as the losing network connection is quite annoying and has me looking for a different manufacture of Docking Stations.
