DisplayLink Forum - Having issues with Toshiba dynadock

System:

Lenovo Ideapad Y510p dual GT750M
16GB RAM
win8.1
Displaylink software 7.7MO
Nvidia drivers are updated to the latest

Problem:

Initially it worked fine but the USB mouse was freezing up all over the place; so then I updated the software and then it told me something about incompatible display drivers so I proceeded to uninstall everything displaylink related then reinstalled (of course with each successive reboots)

After that; I was getting a blank monitor with the latest everything, tried to get into the Nvidia control panel while actively using the dock but that doesn't work so I unplugged it and turned on SLI then plugged the dock back in and behold it works but with one problem:

I'm getting all kinds of artifacts that won't go away when I drag windows or access the Modern/Metro UI and then of course the desktop background isn't fitting the whole screen as it should but as I keep writing this I keep discovering more! :D

I did use the display link tool for compatibility and it passes; I had it do the zip file thing twice on two different configurations; once for SLI and once for not.

Then I proceeded to try changing the resolution on the display that is attached to the dock and that solved the artifacts issues as well as backgrounds, etc

So my question is; and I assume that the displaylink technology works better WITH SLI than without? Is there any reason to NOT use SLI? (I don't seem to notice any noticeable difference using it (before I got the dock) but haven't tried gaming with it with the dock to see if there's any difference really.

I have those files just in case :)

Crazy thing is this works much better on the Lenovo Helix which only has the intel 4000 GPU and I'm amazed this works with my Dell Ultrasharp 24" IPS monitor :D
