A friend of mine gave me his spx01's to use with my P4. They didn't have any instructions with them, and I haven't been able to find anything on the web about it (if there is any kind of settings I have to change on the controller, or in the DJI Go app, or on the goggles themselves). I have the HDMI upgrade already installed on the controller, and all the cables needed to hook it up. When I hook up the goggles, the picture on the tablet goes to black & white, and freezes. The PIP on the goggles is working, but the main picture is blank. I may have to take the whole thing to the hobby shop to have them look at it (the nearest one is over an hour away), so I thought I'd try here. Any help would be greatly appreciated.
