Connecting a smartphone to Xiaomi TV opens up a lot of possibilities, from streaming high-resolution video to using the phone as a remote or gamepad. However, not all users know that modern Xiaomi TVs (Mi TV A Pro, Mi TV Q1/Q2, Redmi Smart TV and others) support 5 different ways of synchronizing โ from wireless protocols to wired connections.
