I have a Samsung 65” in the conservatory and two 42” in two of the bedrooms. We don’t go very far from the house due to the wife’s health problems so the tv is a major part of our day to day life. @Wmc No it doesn’t dominate the room, the lounge is 5m by 5m square so pretty large. The 65” in the other lounge has more of a presence as it’s a smaller room.
Did you do the maths or were advised on which size or did you go out and buy?
How many feet would you say your sofa/chair is from the 77 and 65?
I’ll explain how it works for the benifit of others with yours and mine.
