Client went out and bought three LG OLEDs for a gym. The LG remotes really blast their signals. When you turn on one TV it turns on all the other TV's.

Tried set ID in the menu but turns out that is for some other type of set up.

Tried to repair each remote but they still control each other. I found a post online that claimed holding the home and back buttons together for 5 seconds would do this but no luck.

Is there any sneaky way to isolate LG TV's so the remotes don't control the other TV's.

On that note, I have another job coming up with four TV's together. Simple set up so I don't really want to use control, but do Sony or Samsung allow you to dedicate a remote to each TV so they don't power each other on?
