Hiding TV wires: in the wall, cord cover, or leave them?

The three ways to deal with the cords under a mounted TV, what electrical code allows inside a wall, and which option suits renters.

A mounted TV looks best with nothing hanging below it. There are three ways to get there, and the main difference is the power cord.

Why the power cord is different

A TV's power cord is not allowed to run inside a wall. Electrical code doesn't permit a regular appliance cord inside the wall cavity, which is why "just push the cord through a hole" is the wrong fix even though it's common.

HDMI, soundbar and network cables are low-voltage, so they can run inside the wall through proper wall plates.

Option 1: cables in the wall, power cord on the outlet

Two low-voltage openings, one behind the TV and one down low, with clean wall plates. HDMI and soundbar cables run inside the wall. The TV plugs into an outlet as normal, so this works best when there's already an outlet behind where the TV hangs. (+$89)

Option 2: everything in the wall, power included

An in-wall power kit puts a recessed outlet behind the TV, fed from an inlet down low that plugs into your existing outlet. It's made for exactly this job, so your home's wiring is never opened and you don't need an electrician. Nothing shows at all. (+$199, kit included)

Option 3: a paintable cord cover

For renters, or walls that can't be cut, like brick or a wall with a fire break in it, a slim cord cover runs the wires down the wall surface. Painted to match the wall, it nearly disappears, and it comes off cleanly when you move. (+$49)

Or leave them

Not everyone wants the wires hidden. In an apartment, opening the wall isn't always allowed, and some people just don't mind a cord. That's a fine choice too.

Use cables you won't want to replace

Anything going inside a wall is a pain to swap later, so use a certified HDMI cable. For long runs, use one rated for in-wall use (CL2 or CL3).
