Does anyone know if televisions usually share the same code for power when transmitting on a remote? I have a location on a covered patio that I would like to place a TV that is near a wall mounted TV indoors. Using the Toshiba FireTV remote does indeed accidentally control the indoor TV when outdoors. My concern is if I order another identical, or even a Roku TV that I will have that issue. Any way to ensure remotes are 1-to-1 for a given television?
