HDMI output not supported
I feel like I am in the Twilight Zone. Up until 2 weeks ago my phone was streaming perfectly to my TV. A little background .. I am a Directv client and an AT&T customer. I have a cabin in a fairly remote area. I receive internet service really well from AT&T. I use a lightening plus an HDMI cord to stream from my phone to my TV. Now I receive an error message, “HDMI output not supported “. My husbands phone still works fine. I have tried reloading the Directv app a dozen times, even reset my phone. Still same error message. AT&T says it is a Directv issue and vice versa. I have spoken with Apple and they have no idea. Two of the ‘higher’ level techs at AT@T didn’t even know it was possible to stream from your phone to your TV!!! HELP!
