ThinkPad Yoga 460 (20FY0002US) no video on display 2 (HDMI or Mini DP)

I've had my Yoga working almost flawlessly since purchase.  I use a Wacom Cintiq without issue and our of no where, I get a black screen on display 2.  I've tried multple displays and cables.  I am aware converters do not work so these are straight connections.  Sometimes through DP, the laptop screen will flicker like crazy and I need to unplud the Mini DP cable.  I uninstalled drivers but that didn't help.  The second display is picked up by Windows, it just doesnt show video.  Any ideas?

Re: ThinkPad Yoga 460 (20FY0002US) no video out on HDMI

I've been messing with drivers, I have the screen duplicated and the primary screen is back. 

 

Mini Display port out seems to be working.  I know they are both tied to the Nvidia GPU.  There has to be something I am missing.  Plugging in HDMI doesn't crash anymore.  Windows sees both devices, both displays.  Its just there is not video displaying on HDMI out.   

And we're back...
