Done some more testing on this and I think I can say with a high degree of confidence that this is not a DJI / Lightbridge issue, but a GoPro issue. When I connected the GoPro4Black directly to an Atomos Ninja Blade using a Micro HDMI to HDMI connector in 4K mode and hit the record button, the output to the Ninja Blade went blank. Tried it several times, with the same result.
To clarify the issues on this thread with respect to GPH4B / Lightbridge record and output states, here are some screen shots of the testing
My setup used for testing
My Setup used for testing
Direct output from GPH4B to Ninja Blade (video feed comes in at 1080p - top left info on screen-
the Ninja Blade auto detects the incoming video signal format and displays)
Output from Lightbridge Ground station to Ninja Blade with GPH4B set to 4K in preview mode
Lightbridge is sending out a 720p feed (although I have had 1080p outputs as well. Can't figure
out why it changes from time to time)
Video feed directly from GPH4B to Ninja Blade in 4k record mode - No signal detected from the GPH4B
Looks like we need to get onto the GoPro forum and ask them for a fix.
