I have the same monitor, exact same operating system (ubuntu 16.04.1)/displaylink driver, with a very similar issue. A frozen state of my main screen shows up on the monitor for 5 seconds, before the screen goes black again for another 5 seconds. This repeats around 10 times before the monitor goes black completely.

Very annoying after spending countless hours trying to debug this. Luckily I ordered on Amazon prime, and I'm likely going to return this and get my money back.
