Displaylink Manager 1.4 sees the monitor and reports as installed

Mac Display sees the monitor and allows me to adjust positioning

BUT, I only see black, black, black screen.

What else should I be doing?

I've been having the same problem and have tried many different cables (all bidirectional ranging in price from $10 up to $60 with the same result). I have to open the System Preferences - Displays and hit the Gather Windows button and set the resolution down from 4K to 1920x1080 to make it display any images on my monitor. Incredibly annoying that I have this beautiful 4K LG monitor to use a fraction of the resolution.
