OK, I'm a newbie to the FPV goggle arena and I bought a pair of Fatshark Dominator HD goggles at the same time I bought the newly released HDMI output module for my Phantom 3 Pro. I installed the HDMI output module, which was extremely easy, and tested the output by connecting the HDMI output it to several devices and it works perfectly. I then connected it to the Dominators and cycled to the HDMI 2D input and all it does is flash 3 times and then nothing - just white screen. Note that I can't get anything on these brand new goggles by connecting to other input sources either so I might have a defective pair of goggles right out of the box. I would sell them but I don't want to sell a pair of defective goggles to anyone. Any advice would be greatly appreciated!
