unable to get video from Tx hdmi port

[scriffij]

I have latest software and firmware and now I can't get video from TX HDMI pro. I either get the word 'booting.....' or I just get the 3DR logo on my external monitor? This used to work just fine with previous firmware and app. Ay ideas why with the latest firmware this happens. Video is fine on the tablet.

Has nothing to do with the firmware.
If you get the "booting " message, just power-cycle the GoPro and everything is fine.
Connect the HDMI monitor first, then turn on Solo and controller
