Try configuring the monitor to use DisplayPort 1.1 if possible.  I have been
having this issue for a while and just this morning decided to poke around the
monitor settings. Switching the monitor to 1.1 fixed the problem. 

My gear.  Dell XPS 13 9350, AOC u3477pqu 3440x1440 at 59.94Hz

The USB Type-C to DP adapter does claim to support DisplayPort Version 1.2, so
I am not sure which piece is at fault yet.
