How do I hide the wires to my wall-mounted TV?
You can hide wires from a hanging TV on a wall by putting them behind the wall. However, this requires some drilling or buying an in-wall power kit. Alternatively, you can use what’s called a “raceway” — a hollow metal or plastic channel — that runs down your wall and hides your cables from sight. To get the job done right, and avoid risking damage to your wall, hire a professional TV wall mount installer near you.
