I have two Vizio TV's, one has a Roku Premier+ and the other with a Roku Ultra LT. The Ultra is capable of turn TV on and off and controlling the volume. The problem is the one remote controls both TV's at the same time. Power on and both TV's power on. Remote is only paired to Ultra not the Premier+, it has no other control on the Premier+ but power on off and volume. I turned off CEC on the second TV and it makes no difference. Any Ideas?
