Title:
  nvidia proprietary driver does not output to HDMI screens

Status in nvidia-graphics-drivers-367 package in Ubuntu:
  Confirmed

Bug description:
  When attaching an external screen to my Macbook Pro 15" Retina the external 
screen stays blank.
  nvidia-settings report the screen correctly.

  There are three options to attach a screen:

  - HDMI directly
  - via Thunderbold port 1 and 2

  I use a Moshi adapter.

  Cable and adapter used to work properly, HDMI direct worked till
  16.04.

  Using Nouveau driver the external screen works fine (except for
  overlapping screens) from TB port 2 and HDMI port.

  TB port 1 works fine with VGA.

  Thus I presume there is an error in the nvidia 367 driver
  (I haven't tried the latest update 375.20 from NVidias site yet)

  I have reported this error under #1650891 (nvidia-367 driver)
