My parents recently got an LG 27LQ625S television, and have it connected to the small Verizon cable box...not sure model, but it's the "media client" box. They are old and not tech savvy at all, and would like to be able to control (most functions of) both the smart TV and cable box with one remote—either the LG or the Verizon one. Is that possible, or do we need to get a "universal" type remote?
