Toiday, I don't think you understood what gfunkj was asking (I say that only because I'm here looking for an answer to the same question).
I bought an LG TV for my mom a few weeks back. Setting it up was extremely easy, and at one point point in the set up it asked to specify how we got TV (a cable company set top box), but it also let us specify which provider it actually was. The guide was then integrated with the webOS experience and only one remote (the LG one) was required...incredibly slick!
So now I've bought a 2016 LG TV but when I go through the same process (so HDMI from my cable company's set top box), I *don't* get the option to specify how I *get* TV. It only shows Antenna and its greyed out so I can't change anything.
This *could* be a change in webOS from the 2015 model I got my mom to this one, but that seems odd.
So my question, which I think is the same as gfunkj's, is - How do I get my LG TV to recognize my cable company's set top box so I can synch its guide to the tv's Guide app?
Thanks!
