Same here. Before I was using Xubuntu 12.04 LTS, everything was OK. Installed Xubuntu 16.04 from scratch and problem started - external display (HDMI cable connected to Thinkpad X220's display port via cable adapter) goes dark for a split second randomly. I have noticed this happens mostly, if not even only, when I watch a video on that screen. It can be a movie opened with VLC in fullscreen mode or youtube video in the browser's window. Interesting fact - it happens even if the video is paused. I highly doubt this is a hardware issue as it worked properly on 12.04 and on Windows 10. I also do not believe this to be related to faulty electric equipment at home as the whole setup is connected to an UPS so I hope whatever power fluctuations are there, get filtered out. Keeping mouse pointer either on main laptop screen or on external display, or moving fast between them does not make any difference.
