It's a "media-ready wall" and it is above the fireplace. Friends of ours have another model that is almost identical and they have the TV over the fireplace. I am not sure if they paid for the media ready wall or just did it themselves. Haven't heard any complaints from them. They've been in their place nearly 5 years.
We opted for no mantle or fireplace surround; will do our own later (still no mantle). Tilting bracket, for sure. Fully articulating one upstairs (in case we move furniture around or get a stationary bike or elliptical).
