Thought I'd add my 2 cents worth. I only just tried adding a second monitor in addition to my laptop a few days ago and had this problem. Tried many of the suggested solutions - none worked. Works OK in windows 10. Also works OK in 16.04. Tried using a HDMI to digital adapter at the monitor - did not work. OK in windows 10. Alas cannot try the adapter at the computer as no digital or dvi plug. xrandr pretty as in others shown above - HDMI-1 disconnected. Hopefully this will be fixed before too long.
