Will the DJI RC Pro Controller output live hdmi from the Mavic3 at 1080p? We seem to be only able to get 720 out of the DJI Air2 S with the RC Pro, or maybe we are doing something wrong? Thanks!!!

Hi there. Thank you for reaching out. You may refer to the information below for the DJI Mavic 3 Image Transmission Bandwidth While Live Streaming:

The maximum transmission bitrate for DJI Mavic 3 is 18Mbps.
1080p 30fps : 12Mbps
1080p 60fps:  18Mbps
The downlink bandwidth includes 10MHz/20MHZ/40MHz, which can be selected based on interference. Hope this helps. Thank you for your valued support.
