Hi James,

I know the monitor and DVI cable work. I've never tested the dock with Windows 8 (the dock came after 8.1).

It's now working ... but I'm a tad confused.

Here are my steps:

Plugged in dock
Installed Lenovo drivers (failed)
Uninstalled Lenovo drivers
Installed DisplayLink beta driver
Drivers installed cleanly, but monitor never detected
Rebooted multiple times, still no luck
Gave up, went to work for a day (used machine there, no monitor), came home
Plugged dock in as USB hub (keyboard + mouse) but then connected monitor directly to Helix via VGA
At this point, the same monitor is physically connected Helix-dock-DisplayLink-DVI-monitor as well as Helix-VGA adaptor-VGA-monitor
Monitor lit up and I worked away
Noticed that my mouse was disappearing and screen alignment was wrong
Went to Screen Resolution control panel and saw three screens: built-in, and the external monitor twice
Disconnected VGA, monitor still worked (evidently DVI)

Is there anything useful for me to investigate now? Or just be happy that it's working?

Do you want another log, so maybe you can diff them?

(PS. Thanks for the beta drivers + these forums. Amazing support for hardware!)
