ZTE Spro 2

I'm unable to run the projector on my ZTE Spro 2 using the TWC TV app. It gives me the message, "TWC does not currently support HDMI video out from this device. Please disconnect HDMI to continue using TWC TV." I don't know why it is referring to HDMI because it is running from the installed Android app and not from an HDMI input. Any help is appreciated. Thanks!

Application is written to not allow casting, I suspect.
