How to Hide TV Wires: Choose the Right Cable and Power Route

A surface cord cover is usually the first option to consider when you want fewer visible wires without opening the wall. For a concealed route, plan AV cables separately from power: an ordinary TV power cord or extension cord stays outside the wall. A suitable listed power-relocation system or properly installed electrical receptacle can provide power behind the TV. Choose the method after checking wall construction, cable access and the movement of the mount.

List the connections before choosing a cover or kit

Count the cables that actually need to reach the TV. A streaming setup may need only power and a soundbar connection; another room may have a console, receiver, antenna and wired network connection. Note both the cable diameter and the size of its plugs. A narrow channel may hold a cable but lack space to turn its connector behind the TV.

Separate three questions: where each cable starts and ends, which part must remain accessible, and what moves when the TV extends. Sketch the route with the TV in its normal and farthest intended positions. Decide where the equipment will live before buying cable lengths or cutting openings.

An HDMI lead is not a power lead, and a brush-style wall plate is not an electrical receptacle. Packaging described as a “concealment kit” can refer to different products. Check the component list and instructions rather than assuming that every kit supplies both signal routing and a suitable power system.

Use a surface cover when the wall route is uncertain

A surface cover hides a cord along the face of the wall. It can work well on a wall you cannot open, in a rental where alterations need permission, or when masonry makes a concealed route impractical. It remains a visible channel, so choose its position as part of the room layout rather than expecting it to disappear completely.

Select a cover intended for the cables being routed, with enough capacity and appropriate bends and fittings. For example, Legrand's CordMate C100 is an on-wall cord-cover product with adhesive backing and a paintable finish. It is not a substitute for a listed building-wiring system, and one product's capacity does not apply to a whole cable bundle.

Lay out the route before attaching it. Keep plugs accessible, avoid pinching cables, and follow the cover's instructions for attachment and painting. Adhesive may lift paint or damage wallpaper when removed, so “no drilling” is not the same as “no possible wall damage.” Confirm landlord permission where needed.

Keep cords away from walkways and places where furniture can crush them. The CPSC home-safety checklist discusses cord damage and trip hazards. Hiding a problem behind a cover does not correct an overloaded, damaged or poorly routed cord.

Understand what a power-relocation kit does

A suitable power-relocation system has a defined path from the existing room receptacle to an inlet, through the system's specified in-wall wiring, and back out at a receptacle behind the TV. The TV's own cord plugs into that upper receptacle on the room side. The connecting supply cord at the lower end also remains outside the wall.

That is a functional explanation, not a wiring diagram or permission to assemble the system from loose components. PowerBridge's ONE-PRO instructions distinguish its inlet, outlet, building cable and exterior supply cord, and specify wall and installation conditions for that model. Other products may use different components or connections. Follow the current instructions supplied with the exact listed system.

An ordinary TV cord or extension cord must not be run through a concealed wall cavity, including inside a tube. PowerBridge's FAQ explicitly distinguishes that misuse from its intended system. Calling a cord “heavy duty” does not turn it into the specified in-wall wiring. Do not splice a normal cord to building wire or improvise an inlet from an outlet.

Some products combine power components and AV openings in one assembly. Legrand's CPT306WV1 listing is an example of a specific power-and-cable kit, not evidence that any two wall plates provide the same function. Verify the exact model, listing, wall compatibility and local installation requirements before buying.

Check the cavity before planning openings

An empty-looking patch of drywall does not establish an unobstructed path behind it. Framing, horizontal blocking, insulation, pipes, electrical wiring and other systems can interrupt the route. A stud finder can contribute information, but it does not prove an entire cavity is safe to cut or fish through.

Have uncertain construction assessed before making openings. Do not cut a stud, drill through unknown blocking, or disturb a fire-resistance assembly simply to connect two convenient points. If the intended route cannot be established, a surface cover or a different equipment position may be the appropriate solution.

Use the template supplied for the actual cable or power component when an approved installation is ready to proceed. A wall-mount drilling template marks bracket fasteners; it does not define the cutout for a power inlet, receptacle or AV plate. Their dimensions and locations serve different purposes.

The upper components must also clear the wall plate, moving arms, TV connections and ventilation. A box centered behind the TV can still collide with the mount. Resolve the screen height and bracket layout before fixing the cable openings.

Know when the work belongs to an electrician

Adding or moving a branch-circuit receptacle is electrical work. An appropriately qualified electrician should assess the circuit, installation method and applicable local requirements. A generic mounting guide cannot establish whether a permit is required at your property or whether an existing circuit is suitable.

Power wiring supplies electricity; it does not carry your HDMI signal just because both connections appear behind the TV. Plan the AV route separately, using cable types suitable for their location and the required separation or enclosures. Do not mix power and AV in an improvised shared box.

Masonry also changes the routing problem. Cutting a channel can affect the structure or hidden services and should be assessed before any work begins. The brick and concrete guide explains why a visible finish does not establish the construction behind it. A cord cover can be a useful finished solution rather than a temporary failure to achieve an in-wall route.

Test cable length through the full movement

Full-motion mounts need a route that works both extended and parked. Measure along the intended cable-management path instead of only measuring the straight-line distance between the TV and wall. Allow the movement and bend radius specified by the cable and mount manufacturers; there is no universal extra length for every arm geometry.

Check the setup slowly through its intended motion while watching the connectors and arm joints. Cables should not pull tight at the ports, become trapped between folded links, rub sharp edges, or hang where they can be caught. Use the mount's intended guides without overtightening ties around the cables. Extra cable should remain controlled and accessible rather than becoming a loop in a walking area.

Test the signal with the actual equipment before the route is closed. Label the accessible ends so a future device change does not require guessing which lead belongs to which connection. Keep access to plugs and service points that the products require.

Choose the finish and define the scope

Choose a surface route when you want accessible cables or cannot verify a concealed path. Consider an appropriate power-relocation system when the actual wall and installation conditions fit its instructions. Involve an electrician for branch-circuit work, and reassess the location if the route would require uncertain structural changes.

When comparing installation prices, separate the cover or kit hardware from labor, and ask whether patching or painting is included. TVMounty's catalog lists in-wall labor for suitable drywall separately from supplied kit hardware; the cost breakdown shows dated examples of that distinction.

For help planning the work, configure a TVMounty installation request with the cable finish you want and the equipment details. Your address is used to check coverage and any travel fee, and the requested arrival window needs confirmation. Agree on the actual route and any scope change before work begins, with power components and signal cables clearly identified.
