Unfortunately tedious. You have to start the projector with the Xgimi remote control, then about 6 clicks to select HDMI source. Only then do you arrive at Apple TV :(

You can simply connect the Apple TV to the XGIMI Horizon Pro 4K and don't need to deal with Android to use it. The Horizon Pro 4K supports HDMI connections and is compatible with various devices, including media streamers such as Apple TV. You can connect the Apple TV to the projector via one of the HDMI ports and use it without any problems.
