A:AnswerWe used it on a non smart tv with an HDMI port and using an hdmi cable... cannot speak about the app for wwe but I would think it should work if you have the ability watch it on your iPhone SE it should be viewable over the hdmi cable connected to the tv and the adapter to the iPhone.
A:AnswerThat’s a neat question. I’m not sure about the iPads with lightning ports, the only iPad I have uses USB-C. If the iPads with lightning ports work with this, you shouldn’t have an issue.
I did test this idea with an iPhone XS Max and iPhone 11 Pro Max.. You can see and hear everything coming from both ends. It basically mirrors the phone.
A:AnswerNot if you’re planning to use the directv app. Directv app will not work with this device due to them trying to avoid people signing into a friend’s account and watching everything for free without actually having a directv account.
A:AnswerI did have one instance of picture but no audio but not what you are asking about. The problem occurred in a hospital where I had to plug into a wall connection, not directly into the TV. I assumed the problem was with that connection as it worked with all other TVs I have tried it on.
Suggest trying either a different TV, or different HDMI cable.
