LG Smart TV YouTube App Hidden Gem: Device Pairing

This weekend I discovered something neat on my LG Smart TV (a 42LV5500): in the YouTube App, there’s an option to pair your mobile with the app itself.

Once paired, you can use your iPhone to play a YouTube video on the TV.

Now, it’s nothing like AirPlay mirroring but more a remote control feature as the iPhone doesn’t stream the data to the TV: it’s the YouTube App on the TV itself that fetches the video from the YouTube servers (viz. you may discard your phone after the TV starts playing the video).
