Dual Monitor issue with Radeon RX 480

I recently built a new PC and used the above graphics card, however I can't get a dual monitor setup working.  Windows 10 detects the monitor, and allows me to move windows into the monitor, however the monitor stays black.  Swapping cables or ports between the two monitors does not solve the issue.  However the second monitor works fine in windows safe mode, as well as during boot.  However the moment windows 10 finishes loading the second monitor goes black and will not return.  I have tried several reinstalls of the drivers and have run out of ideas.  Any help would be appreciated.
