Are you saying that the EPS-1 adapter needs to fit into an power strip that sits behind the TV? Yup, it's definitely going to be a problem, or is it some other configuration.
On another issue, I and a few others cannot post any clipboard or other images like yours, to this reply box. Cox tells us that this is not possible, at least for selected areas. I'm in SoCal and using Win Firefox. So Cox, how do some of this posters get to do this...am I missing something. In the Insert pulldown below, I cannot even do a file insert...bummer! I can copy/paste text and URL's.
Power adapters are the bane to concealment. No matter how thorough you plan, you'll always be confronted with a thicker "wall wart."
Where will you place the Mini Box...near the TV on a shelf?
Who made the TV mount?
You'll need to check the manufacturer's website for a shelf designed for wire management. Not just wire management but wire management designed to easily manage wires. For example, would I need to remove everything from the shelf to access its power strip?
There are basically 2 schools-of-thought: conceal all coiled wires near the TV or conceal all uncoiled wires to/from the TV. Sometimes the coiled option only works with ceiling mounts.
