Most people don't rearrange their furniture to fit their TV. They buy a TV to fit the viewing distance in their room.
It seems I’m strange then, which I’m ok with. I do think a lot of movie and tv enthusiasts unconsciously do start with the tv though.
In my opinion, you say your comment because society has already conditioned most people to center your living room around a TV. If there was no TV, almost everyone would have furniture set up very differently, and it would be a lot nicer room to sit in. I believe people here with no TV in their living room would agree. Chairs and long couches would go more into the middle of an area facing windows and the light, and you certainly wouldn’t sit facing a long blank wall and then say, “hmmm, I think a TV would go well here so that I don’t just have to stare at the paint.” Chairs would face each other in a style that would encourage communication and the ability to look at people.
In my current situation, I can move my wide 10-foot couch back to a distance of around 15 feet. This would allow for a couple other nice seats, and then a large TV. However, what size TV would everyone on this forum say you need for 15 feet? So now, my couch has been moved in to 8.75 feet, and I have rearranged the room to provide a second seating area at the other end of the room that is not focused on the TV, and instead takes advantage of the view. I also set up a 6-foot-long dining table directly behind my couch to use as a workspace and eating area that will be facing directly at whatever TV I get. Because it is directly behind the couch, it is not like an island with all 4 sides available for chairs, unless I pull it back off the couch if guests come over.
I recently looked for a new apartment, and when I did, the primary consideration was the layout of the living room and whether I could have a nice TV-viewing area. If not, that apartment was not up for consideration anymore. I start with where the TV will go, and then design the rest of the area based on that. If the design doesn’t work, then that apartment/house won’t work either. Houses are slightly different because they often have the opportunity for a dedicated entertainment area of some sort.
You might be correct that a lot of people don’t consider a nice TV area as a deal breaker, but I do it consciously because I want to enjoy it, and setting my home up for guests becomes secondary at best.
Also, many people on this forum have dedicated home-theater rooms or entertainment areas, so I would say they set their house up with that idea. Nobody purposely wants to go hang out in the basement when they have a nice living room, unless it’s because they strategically designed to put a big TV down there. I’m quite sure they didn’t have a bunch of couches set up there before the TV arrived. Hehe. They are fortunate to have that space though. In that case, I also believe the TV becomes the first consideration.
Anyways, just my opinion. I guess I’m different.
