I have a very similar behaviour on my i7 PC with two Benq monitors: 23" vga and 24" dvi. Dvi one can blink several times in a row or not to blink for some long time. Haven't found any consistent pattern about it. I am running Ubuntu Gnome 15.10 that I have upgraded to 16.04 recently. Problem was from very beginning and continues after upgrade.
