What is the function of the HDMI port on the flightfeeder unit?
To state the obvious… it provides HDMI output 
The flightfeeders provide a little status display that can be useful for troubleshooting if you plug a monitor in there.
I did plug in a TV using HDMI cable but all i saw on screen was this message…“video mode not supported”
Your TV does not support the low resolution the FlightFeeder outputs.
You don’t need the HDMI output anyway, just leave it be.
Thank you Weidehopf. I was just curious. There is no real need of the port as you said…
