Video output stopped working

[gchristian]

I'm using a D3100 docking station with my Dell XPS 13 laptop running Windows 10. Everything was working fine until one day I plugged the laptop back into the docking station after taking it elsewhere, and the video output stopped working. Keyboard, mouse, ethernet all work fine, just no video.

I tried downloading and installing the latest driver (7.9 M4) from here:
http://www.displaylink.com/downloads/windows

But when I run on the downloaded file nothing of substance happens. I get a pop up asking if it's okay to run the executable, click yes, then briefly get a window with a progress bar saying "installing displaylink software" that disappears after a second or two with no confirmation that anything happened.

I've also tried rebooting a couple of times, power cycling the DisplayLink, and every USB port on my laptop. No success.

The video output works just fine if I plug my HDMI cable directly into the laptop.

Any advice or suggestions?
