Installed the new HDMI board, tuned on tablet, tramsmitter, aircraft. Went into DJI App and set dual view for tablet and HDMI out and turned on OSD. All I get from the HDMI out put is the OSD, no video. Video is on the tablet though. Im using a HDMI cable from a Canon HD camcorder. Are the pinouts on HDMI cables standard or are they proprietary to various devices? I don't have another cable to try and my little hayseed hick town couldn't spell HDMI, so I will have to order a new one. I don't really want to buy yet another cable if I don't need one. Yes, the cable does work with the Canon camcorder. Any thoughts?
