That's interesting. It's pretty much a pandemic in the north east as far as I can see. Out of 8 people who live on my street, I know 3 of them have a TV over the fireplace, (I haven't seen the others). And all 3 TVs (again, a chunk of electronics) look crass over something otherwise beautiful.
By the way, neck strain is only one piece to a weird puzzle. There was considerable talk about eyes drying out quickly when the head is tipped back slightly. I don't know because my TV is centered at sitting eye height.
Its all personal preference, just because you don't like something doesn't make it wrong. Never heard anything about eyes drying out, gota blink once and awhile.
