    Dell 7480 with Intel HD Graphics 520- external HDMI monitor not always detected

    Dave@work

      I have a  new Dell 7480, that on boot or resume fails to see the 3rd monitor without launching the Intel HD Graphics Control Panel  -> Display  -> Multiple Displays -> Detect.

       

      Once it finds it;  it works fine until the next time I restart or resume, and I find the 3rd monitor is missing again.

       

      - current bios update

      - Windows 10 1703 (OS Build 15063.483)

      - Intel hd Graphics 520 Driver veision 21.20.16.4627

       

      The best i can tell all the drivers are up to date.

       

      Did I miss any information?

       

      Any ideas how I can get the laptop to remember the 3rd monitor?

       

      Thanks!
