RE: Dell 7450 AIO How to add a second monitor via HDMI out or Disport

Turn out to be a missing video driver (Intel HD Graphics 510 / 530 / 630 Driver) for windows 7.  I had a Colleague look at the problem (second set of eye's) and he notice that device manager flagged an unknown device.  The unknown device was the video controller.  

I'm able to use a second monitor via the display port only.  I'll work on the HDMI some other time.

Thanks Brad for your help.
