It would sure be nice if someone would make a receiver capable of snagging the downlink video of any of the DJI (or other) drones. I would like to be able t (easily) show my clients what I am shooting. Also in search and rescue it is helpful to have multiple eyes on a screen.
If the Pro controller has HDMI out... or any type of video out I would think you could set up some kind of wireless relay with a receiver on the TV... I recall someone doing it with Chromecast or similar. No wires to the TV but the controller area becomes a flustercluck ;-)
