I live in an area where broadband internet isn’t available. I have DirectTV satellite for TV and an iPhone with unlimited 4G data and 15 gb hotspot data. I have a Jetpack from Verizon that gives me 15gb data as well. I would like to mirror movie content from the iPhone to the TV, and was planning to buy an Apple TV box for this. But from what I read, the movie would be displayed at iPhone resolution and not the 4K supported by the TV. Is that right? There’s no point getting Apple TV if I can’t watch in at least HD. I have an Amazon Prime membership which includes lots of free movies and shows, but if I can only watch in smeary blown-up iPhone quality then the Apple TV doesn’t do me much good. Any suggestions?
