How to use smart share?
LG Smart Share is a great way to access all of your music, videos and photos
from the comfort of your own sofa.It sends all of your favourite multimedia
from your PC, laptop, tablet or smartphone directly to your TV, and, best of all,
it's wireless!

I got smart share software and plex media server from this link:
