Not sure how you did the test, as I test Gopro3 Black, Gopro4 Black at my hand, which are working fine with our Lightbridge, if you have any further issue, please kindly send me your email to support@dji.com

The LB buyers are lying then ??? you read the forum ??? already read how many users have  this problem ??? LB does not accept resolutions above 720p. update your lb and use it for 3 or 4 days with a GoPro 4 and see what happens...

The initial issue as I understand it was that the GoPro when using higher resolutions to record, would lower the HDMI out put to 480p.  The LB would not accept that resolution until we changed the firmware.  I have used the LB on a P2 with H3-3D gimbal and the GoPro 3 Black as well.  

My Lightbridge stays black with a GoPro 3+ BE. Settings are 2.7k 25fps, protune.
I have to use the output of the GCU: analog.
