#1 How to Screen Share?
LG TVs are equipped with innovative features that make it easy to share screen and display content between your external devices like your PC, tablet, smartphone and more. There are multiple ways to connect and they all depend on your network connectivity and the type of device you wish to share.
LG Smart Share is the tool that lets you connect your compatible smartphone, tablet, PC, camera, or USB device to your TV and showcases all of the device's audio, video, and photo content in simple menus on your screen.
In the case you are using a Mac device to share your information, AirPlay will only allow you to stream to a Mac device, however LG supports AirPlay 2 in its 2019 models.
