Welcome JerGisi,
I have an LG tv also so I suggest the Amazon Fire stick 4k or some other reliable streaming device to get started. Find and download a reliable IPTV service app. This subscription will provide you with their URL address. Then download the TiviMate app paid version to access all of the features & settings that you don't get with the freebie version. Make sure you always USE the latest versions of these apps when downloading. Good luck and always enter and double check for any errors.
