Hi

Beovision 7-40 mark iv, sky+ HD box, apple tv, slingbox = millions of wires coming from the back of the tv and sprawling all over the floor.  Is there a simple solution?

Motor floor stand?

You can either mount everything on STB brackets and run the cables in socks or relocate everything and run the cables under the floor. It really depends on the room/placement etc. 

A local B&O engineer will no doubt be able to help you out with cable management for an hour or twos' labour. (Which is what I'd recommend).

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.
