I’ve had my UD-3900 for a year now, and have been very happy with it. I just bought a new laptop for my doctorate (MSI GS70 Stealth Pro-006 running Win10 Home), replacing an Asus ROG G750JS-DS71.
My UD-3900 switches between a Surface Pro from work and my MSI laptop, using a Plugable USB 3.0 Sharing Switch. I have 2x27" monitors connected to the UD-3900 along with wired keyboard and mouse. With the new laptop, when I switch over to it, I have trouble getting things to work.
First of all, my laptop seems to go to sleep, even though I have it set not to…I may change that since it sleeps anyway.
Secondly, once the laptop wakes up, sometimes I have to reboot my UD-3900 to get it to be recognized (after which everything works)
Thirdly, the times the laptop recognizes the UD-3900 enough to get a display on my monitors, it doesn’t recognize my mouse, and I have to unplug/plug it back in a couple of times before it works.
