I have same problem
Was also posted up on evdi github
https://github.com/DisplayLink/evdi/issues/74
FWIW - the workaround does NOT work for me
Is basically a problem with evdi being updated almost a month ago now, but no new Displaylink Manager being released
@mlukaszek mentioned the update is meant to come this month
as it stands I am sticking with kernel 4.8 until the new displaylink manager is released which hopefully fixes this issue.
