Why hide wires?
Loose cables make a mounted TV look unfinished. Hiding them makes the TV look built in and keeps cables protected.
In-wall runs
The cleanest option runs power and cable inside the wall to a lower outlet. Codes require approved in-wall power products, so this is a good job for a professional.
Surface raceways
When in-wall is not possible, such as brick or concrete, a paintable raceway keeps cables tidy and can be painted to match the wall.
Shelves and consoles
A shelf or console below the TV can hide sources and cables while keeping everything accessible.
Plan the outlet
A recessed outlet behind the TV lets the TV sit flat against the wall.
