Wondering if anyone has had video issues with Dell docks? My Latitude E7450 is "unsupported" by Dell, however...works great in Windows 10 with this (glaring) exception.

I have removed the filler plate from the dock, plugged in HDMI and a mini display port directly to the back of the laptop. Been running 4k resolution on both monitors this way all day. If I try to use the dock, no dice. I can see the video card detected/losing one of the 2 monitors over and over.

Nvidia version is 353.30
