Hello,

We are trying to add functionality by mirroring the smartphone video stream on a large TV (which is not a smart TV) in our command post. That way the pilot can concentrate on piloting the drone, and someone else can be watching the large TV for whatever it is we're looking for. We tried it yesterday using a Chromecast plugged into the TV, connected to a Verizon Jetpack via wifi, connected to the smartphone running the app via wifi. It worked, but video was grainy and choppy.
I know there has to be a better way to do this, and at the same time, I'd like to simplify it as well. I've been looking at Miracast options such as Belkin Miracast adapter, that claims to eliminate the need for Wifi for it to work with a smartphone. Does anyone have any experience with anything like this? At the end of the day, all I'm really trying to do is to stream a smartphone to a large dumb TV with the best picture quality and simplest configuration.

Any help will be apprecited.

I didn't find the right solution from the Internet.
