To connect iPhone, please use an official Apple Lightning to HDMI MFI adapter from the Apple Store. If the adapter is a knockoff, paid apps will be blocked (Netflix, Amazon Prime, Hulu, etc). Use the official one from the Apple store, you won’t have that problem. Or you can use a Miracast/Dongle to realize the wireless connection.
