I experience black screens for about a second. Usually one of the external monitors only. One external display turns black and comes back after 1 or 2 seconds. This happens >10 times a day and is really annoying. My colleague experiencing the same issue, also using Ubuntu 16.04. Same hardware. At home I have a similar issue, also with Intel motherboard graphics. Different hardware.
