If your PC and your LG TV are connected to the same home network, wired or wireless, you can easily use LG Smart Share to share the videos, music and photos stored on your PC with the TV and other devices.
Features:
LG Smart Share lets you play the videos, music and photos stored on your PC on an LG TV over your home network without any cables.
LG Smart Share is a free and easy to use application for sharing media from a PC with LG TVs. It works with LG Smart TVs running NetCast 4.0 or later, and the Connected Players panel shows which devices on the network can play your content. The program installs the Microsoft Visual C++ runtime it needs automatically, and LG still offers it on its support website. The Sharing On indicator in the main window shows whether your content is currently shared.
