I guess it's safe to say with consumer TV's, this isn't possible. The only source this guy is using the LG TV's are the built-in streaming capabilities, so it would be nice to be able to separate them, but doesn't look possible. I actually created some semblance of separation by partially blocking the IR windows on the TV's to reduce their sensitivity. It actually works pretty well, but def a hack solution.

It's for gym in a mountain community. Hardly anyone ever uses the space. He went out and bought all the TV's and then someone gave him my name.
