Our 2012 came with the 26" tv. Don't know if a 32" would work, based on the wall it's installed on. I just checked and the distance from the outside to the inside of the wall it's installed on is exactly 32". My old, clunky LCD set, not the LED type, is 31" wide and 20" high. So, I would bet that a 32" LED LCD set would fit fine. Just make sure it's not too heavy as I don't know how much weight the wall will hold.
