I replaced my original RCA 40" set a couple of months ago with a new Samsung 43". I would have gone larger, but that is the widest set I could get to fit in my rear mounted TV lift. Even though the new set is the same width as the original 40" it has a larger screen due to the newer low width bezel design and a much better picture.
The only issue was the new set had a VESA 200x200 mounting arrangement where the old RCA was 400x400. I'm sure the fact that the new set weighs half what the old one did was the reason. I removed the bracket from the lift and took it to a machine shop with a drill press and had holes drilled in the 200x200 arrangement. Bolted the new set on and was good to go.
That bracket is heavy heavy heavy.
