Not getting any image on my tablet!

I have an infrared camera directly connected to the HDMI cable that was already installed on the M600 Pro/LB2 (bypassing my SRW-60G).

I know the camera works fine because it works when directly connected to my HDMI monitor.

I turn on my RC, then my tablet, then my infrared camera (that has HDMI output), then my M600.
Tablet starts up my DJI Go app.

M600 Pro shows up with a live blue "camera" button, click on button and I'm in.

No HDMI image.

First time trying the HDMI so not sure it I need to turn something on.

What I currently have:
App Output Mode = HDMI
Output Port = HDMI
Output Mode = HDMI
Output Format = 720P60

Rick, I just posted a new thread tonight . I have had the M600 for almost a year. I have been using a FLIR Vue Pro for over 6 months. Apparently they have done something to one of the firmware updates or the Go app is screwed up.
