Your lg tv may be miracast ready or there may be a software upgrade to support it. if it does support miracast then all you need to do is go to settings\share &connect\Miracast set to on and search and connect.
if it is not miracast ready you can buy a miracast dongle from amazon and such.
AllCast from clockwork mod in playstore will let you send videos and pics to your airplay device (appletv) but miracast will allow you to send your entire desktop.
I would go down the miracast route.
