LG is one of the biggest names in TVs, and with AirPlay, LG users can easily control their devices from their TV. AirPlay works with most Apple devices and allows users to play music, videos, photos, and other content directly on the TV. When using AirPlay with an LG smart TV, you'll need to have an Apple dike an iPhone or iPad) connected to the TV via a cable or Bluetooth connection. Once your device is connected, you'll be able to access the AirPlay menu on your LG smart TV. From here, you can select sources like Movies and TV Shows to watch on your big screen.
