I have been considering a product by the name of Evo Vantage Point for our BV 7-55. It is a wall panel that mounts on the wall behind the TV. It is available in different sizes. It is designed to be placed over any wall outlets. There are multiple removable panels of wood to access wall outlets and a gap around the panels to run wires. My thought is to run the wires straight back from the TV into the Evo.
