Size does matter

My niece and her husband have a large television screen. When I say large, I mean it’s like having cinemascope in the tv room. I don’t know exactly how large the screen is, but you certainly get a great picture, and watching movies on it is a vast improvement over smaller screens.
Apropos of this screen, we had it on one day when the tv in the kitchen was on as well - it was while we were babysitting the house for the family. Both tvs were tuned to the same channel, but the strange thing was that the kitchen one was a second - or perhaps less - ahead of the large screen. In other words, as words were spoken on the kitchen tv, they would be repeated on the big screen. I could dash from the kitchen to the other room in time to hear the same thing twice. I don’t know what would cause this phenomenon: whether it was that the two tvs were receiving their signals from different aerials, or whether they react at different speeds to the same signal is beyond my knowledge. It was just a strange effect.
When I say I don’t know what the size of the big screen was, it’s because I didn’t ask, or didn’t pay attention when I was told (technical things often miss my long-term memory). It’s possible it was as big as a samsung 61 inch LCD screen - I’d have to check with the owners. Suffice to say, it’s a great way for someone who wears glasses and doesn’t see movies well on a normal screen to watch them.
