Hello. I am working on a project where we need to output a high resolution video from the external camera to the FPV or video goggles. We are looking for a goggles that support HDMI in so we can plug a camera using wired connection and get the video. The best goggles I have found are the Fatshark HDO2. Can someone who have Fatshark HDO2 confirm whether they support HDMI input from external camera? Are there any better goggles out there money can buy in terms of video quality (resolution) ?
Keep in mind that the application is not for drone flying! Long range is not needed hence we consider wired option.
We are mainly considering 2 options:
1. Use an external hdmi camera to send video to the goggles. One of the options would be this camera:

I believe this supports hdmi output so should work with goggles that support hdmi IN. Are there any other good cameras with hdmi out?
2. Use a smartphone instead of external camera. Is it possible to connect smartphone to the goggles such as fatshark hdo2 and see the video that a smartphone camera is seeing on a goggles?
