DJI INSPIRE 1 HDMI OUTPUT FROM RC

Just a quick video to hopefully aid someone understand how to hook up to the MINI HDMI port of the RC of the Inspire 1, what it displays, how to choose what it displays and a reason as to why you may want to get a secondary screen like the one I use (Black Pearl by Flysight). In my case I use it to have what the camera sees on a big screen and keep the map on my Ipad at the same time without needing to toggle between both. What can you see on the screen?
