I have two TCL Roku Televisions. They are close together. (I use one as a Television and the other as a Computer Monitor, so they both work at the same time also.). The remotes that came with them both worked on both so If I had something different on one or the other and changed things, it would impact both. I read somewhere that if I purchased a WIFI Remote I could isolate it to one TV and would not have the problem. So, I did. I like that remote since it is not necessary to point to the TV and when I use it, it does not update the Second TV. However the original remote will still update the both when I use it. Is there not a way to isolate the IR remote to work only on that TV? Do I have to purchase a second WIFI remote so they are separate and isolated?
