LG recently rolled out a firmware update to customers who own an LG TV in the UHD UM7X series, enabling HomeKit and AirPlay 2 functionality. LG originally said that this firmware update would be available in October, but the software has come out early.
LG UHD UM7X TV owners can download the new 04.70.03 software update to enable the new functionality. AirPlay 2 and HomeKit support first began rolling out on LG TVs in July.
With AirPlay 2, LG TV users can stream TV shows and movies from an iOS or macOS device directly to the television, with no Apple TV set-top box required. A movie can be started on an iPhone and AirPlayed right to a TV, plus content can be mirrored from a Mac or iOS device to the TV.
AirPlay 2 lets multiple audio sources to play the same content, so a song can be played on a single television set, multiple television sets, or a TV and other AirPlay 2 devices such as speakers for whole home audio.
The AirPlay 2 functionality in LG TVs is linked to HomeKit, so LG TV sets with the new firmware will show up in the Home app on iPhone, iPad, and Mac. In the Home app, LG TV users can do things like switch inputs, turn the television on and off, and adjust the volume. Siri can also be used for these commands, so a simple "Hey Siri" voice request on an iOS or macOS device can adjust the volume or turn the TV on or off, much like other HomeKit products.
LG also plans to enable HomeKit and AirPlay 2 support on its LG UHD UM6X series television sets as well as the LG NanoCell SM83 series or below, but those software updates have yet to be released.
