If I buy two new T.V's, lets say LG, is it likely that each remote control will operate both TV's?

I wouldn't have thought so, but that begs the question - how could you order a replacement remote control as a spare part.

 

1) yes
2) Ask LG to sell you one.

 

Thanks for the concise answer. So if a bar has two or three LG TV's so that it can show different live football games at the same time, they need to aim the remote very carefully? Same goes for sound and colour adjustments.

That would also indicate a potential problem with a second TV in an adjoining room or from neighbours in some cases.

 

they need to aim the remote very carefully?

Yes, and watch out for reflective surfaces. I've seen the employees of such establishments disambiguate by simply using the remote close to the unit they intend to control.

 

Reflections do cause trouble. I can sit here and change channels on my tv, 22 feet away, by bouncing the signal off a mirror that's in the hall.
