It's alright. A good rule of thumb is to lump the accessories with the product they work with. It helps with finding threads in the future.
We're you able to resolve your issue?
For anybody wanting to output video both to a tablet and to your goggles, you need the DJI HDMI module for the P3 or P4 (which is installed already on the P4P+ drone with the screen, but NOT on the regular P4P). I purchased the P4P and bought the HDMI output module separately so I could get HDMI out to some FatShark Transformer goggles, but it didn't work.
So here's the issue: People using the Android version of the DJI Go4 app do NOT have the feature to enable dual video output. It's a feature only on the iOS version of the Go4 app. So when I plugged in HDMI from my goggles, it DISABLED video on the tablet. That's crazy stupid, because you can't control the drone and make setting changes from the goggles. It's not a 1 to 1 video feed, meaning what you see on your tablet (with the control interface) is not what you see in your goggles. The goggles have a completely separate heads-up display (HUD).
Once you install the HDMI module on your transmitter, you need to do a fresh update to the firmware. Then you need to plug your transmitter into an iOS device (ipad/iphone with proper compatibility), power the transmitter & drone on, and then it will do ANOTHER firmware update that the Android system doesn't do on it's own to the actual Phantom.
Once you've done that, in order to get dual output working properly on an Android device, you need to go into the iOS version of the Go4 App and go to the HD video tab in settings, and you will see "enable dual HDMI output", which you enable.
Then power everything down, plug your Android tablet back in, and when you power up, the dual output will work. But keep in mind, that setting still isn't in your Android Go4 App software, it's simply keeping it on because you enabled it while it was connected to iOS.
I really hope that DJI updates the Android software to include the dual HDMI output functionality.
