I have Phantome 3 Professional with the dual display and it will NOT work with HeadPlay 40 channel. My Phantom3 will display perfectly on my HDMI TV.
The HeadPlay will display an HMDI from my Laptop PC on the screen but when I plug in my Phantom 3 I only get a BLUE screen.
and YES, the HeadPlay is on HDMI and YES, my Phantom 3 is setup in the GO App. to display the screen in HDMI.
I also installed Litchi app and it too will not fix the problem on the HeadPlay.
I have a mini HDMI on one end and regular HDMI plug on the Phantom 3 end with an adapter to reduce it from regulary HDMI to mini HDMI so it can plug into the Phantom 3 .... really need any suggestions for help.
