Installing the HDMI module is relatively easy, you’ll need a 1.5mm Hex Key/Alen Key, a small cross head/Phillips screwdriver.

There are plenty of YouTube and DJI tutorials on how to install the module so I will not go into details on how to do this.

I installed the module without any problems, powered everything up and updated the firmware successfully and then the problems started!

I was able to view the live feed using the iPad (as before) but when I attached a HTML device (in my case DJI Goggles) the DJI Go 4 App immediately disconnected and I was unable to view the video feed on either the iPad and/or the Goggles.

Searching around online there are many suggestions on how to fix the problem.

* Clear the Video Cache
* Reinstall DJI Go 4
* Reinstall the latest firmware
* Check the ribbon cables

Nothing seemed to fix the problem!

Thanks to a post by “mecanique62 2” on the DJI Forum which was pointed out to me by Jeff Millard I was able to fix the problem.

The following are direct instructions from mecanique62 2 original post:

“I connected my goggles through the USB connection & selected smooth mode, Then switched back to HDMI & it started working, pretty choppy though, so i connected USB again & switched to Normal mode, then back to HDMI & everything looks pretty good.  I Hope this might help the rest of you.  Oh, I forgot, I uninstalled DJI Go 4 & reinstalled thinking that might have been the cause, but it wasn’t.”

After I followed these instructions everything seemed to work as expected

Now it was time to customise my HDMI Module.
I really didn’t like the idea of having a white lump of plastic on my Obsidian.

I took my controller to a local car bodyshop who were able to match the colour as close as possible and then made me a spray can.

HDMI Module out of the controller, split apart both parts of the module which then gave me just the plastic cover. 5 minutes of sprays, 2 hours drying time and it’s all done.

OK, so, do I have the module I'm going to order drop shipped to you for painting or do you also want the whole controller to make sure the colors match? ;-)

Haha, get yourself to a local car paint specialist. When I took my controller in it literally took 2-3 mins to colour match.

If you do go for it, make sure you 'score' the cover to the module a little bit with a rough sponge, something like we use to do the dishes with. No need to scratch it, just rough it up a little

Nice work!
Wish DJI would get the clue, I suspect they may be coming out with a new version and color options I hope.
FYI - I have had no such problems using my module and goggles along with the tablet together

Back when I was having my troubles. I sent my remote back to Drone-world for them to troubleshoot. When it came back it had a new HDMI Module “OBSIDIAN” version much to my surprise. Oh & I have done a little research on mine. If I connect usb & switch to HD mode. HDMI doesn’t work. Switch bach to normal & everything works fine. Just downloaded new firmware, will have to try it again and see what happens.

I fly my P4P+ with the Goggles attached to the USB connection. It gives me all functionality of the available intelligent flight modes with the Goggles. It also gives me full use of the Go 4 app on the + display. On my non plus controller there is no way short of adding a fully functioning HDMI adapter to do the same. I don’t use the HDMI connection to the Goggles. My 57 year old eyes can’t tell the difference between the FPV connected to the USB and the HDMI. So I hope that adding the HDMI adapter to my non +controller will give me the same option as the +, using both the Go 4 app, and the Goggles via the USB port. The part is on order. I’ll post my experience when I get the part installed. Thank you all for the information, this is why this forum works.

you have the choice of usb to ipad or phone, OR usb to goggles to control the copter.  with the goggles connected to the hdmi all you have is video on the goggles no control.

Then I’ll be forced to use HDMI to keep full functionality of the iPad. That’s OK, as long as I’m not forced to forfeit the iPad altogether. If I want to control the gimbal (really the only thing I use the Goggles to control...) I’ll just revert back to the Pro + controller. Thank you again for this information. You’ve been a great help in getting this all sorted out for me.
