Periodically the external display goes blank; usually when launching an application.  This usually seems to happen more soon after the system has been rebooted.  Sometimes the display returns by itself, other times I must do something like close and re-open the laptop lid to bring the display back.  Not sure how to debug or what is causing the issue.  As best as I can tell it is not a loose cable or physical movement of the devices that cause this.
