The quick answerThe right way to hide TV wires depends on the wall and the cables. Use a paintable surface raceway when the wall is solid, rented or difficult to open; use a manufacturer-designed in-wall power system plus appropriately rated signal cables when the route and local requirements allow it; or keep cables accessible behind furniture when devices change often. Do not assume a television’s ordinary detachable power cord, an extension cord or every HDMI cable can be concealed inside a wall.
The direct answer: choose the route before the television goes up
Cable concealment is part of the installation plan, not a finishing touch after the bracket is already mounted. First list every cable the finished setup needs. Then compare the wall construction, outlet location, device location, mount movement and future access. The cleanest-looking option is only useful if it is appropriate for the actual products and still lets the system be serviced.
Power and signal connections should not be treated as interchangeable. A manufactured in-wall power kit uses components intended to extend power to a finished receptacle behind the television. HDMI, Ethernet, antenna and other signal cables follow their own product markings and instructions. When fixed electrical work is required, use a qualified professional and follow the requirements that apply at the address.
| Approach | Usually fits | Confirm before choosing |
|---|
| Paintable surface raceway | Rentals, masonry, plaster, uncertain wall cavities and installations that may change | Its intended cable types, capacity, fittings, attachment method and indoor location |
| Manufacturer-designed in-wall power kit plus signal route | A suitable hollow wall with an accessible path and a compatible listed system | Wall path, kit instructions, signal-cable ratings, local requirements and service access |
| New recessed receptacle or fixed wiring | Projects that need a new permanent power location or cannot use a plug-in relocation kit | Electrical scope, permits or licensed work that may be required locally |
| Furniture or panel route | Frequent device changes, media consoles, removable panels and situations where wall work is undesirable | Ventilation, connector access, cord protection and a route that does not create pinch or trip points |
Why the TV power cord and HDMI cable are different decisions
A television power cord is flexible appliance wiring. Hiding it is not the same task as routing a low-voltage signal cable. Do not push an ordinary TV cord or extension cord through a wall opening as a substitute for a finished power solution. OSHA’s published flexible-cord guidance, written for workplace installations, likewise prohibits using flexible cords as permanent fixed wiring or concealing them behind walls; residential requirements are governed by the codes and authorities that apply locally.
Purpose-built products solve the problem differently. SANUS, for example, describes an in-wall kit that extends power from an existing outlet to a pre-wired tamper-resistant receptacle at the TV while providing a route for AV cables. The complete manufacturer instructions—not the appearance of the wall plate—determine what that system is designed to do.
Signal cables also need verification. Samsung advises using in-wall-rated cables and a suitable kit when routing connections behind a wall. Check the actual cable jacket, packaging and manufacturer documentation instead of assuming every cable of the same connector type has the same installation rating.
Option 1: a paintable surface raceway
A surface raceway keeps the route visible and accessible while organizing the cords against the wall. It can be the practical choice for brick, stone, concrete, some plaster walls, rental properties or any room where opening the wall is undesirable. A neatly measured vertical run painted to match the wall can look intentional without pretending the wall cavity is simple.
Match the raceway to the intended use. Legrand’s 48-inch flat-screen cord cover is an on-wall residential product designed to hide and organize cords and low-voltage cabling; its cover can be removed to add cables, and the product can be painted and cut to fit. Other raceway systems have different listings, capacities and fittings, so read the exact product specification.
Plan the start and end points before mounting. The raceway should meet the television at a place the screen hides, reach the device or outlet without an awkward offset, and avoid blocking a mount arm, ventilation opening or furniture door.
- Measure the total route, not only the visible drop below the TV.
- Count the plugs and connector heads; they may need more room than the cable itself.
- Check whether inside or outside corners require compatible fittings.
- Confirm how the cover attaches and whether the wall finish can accept that method.
Option 2: a finished in-wall power and signal system
A compatible in-wall system can create the floating-TV look on a suitable wall. The finished installation normally separates the power solution from the low-voltage pathway even when both are presented in coordinated wall plates. Use only the components and cable types the system instructions permit.
The wall still has to cooperate. Fire blocking, insulation, plumbing, ductwork, an exterior wall, a fireplace chase or an offset between the upper and lower openings can change the route. A wall photo cannot prove that the cavity is clear; the route must be assessed before cutting.
Think about replacement, too. HDMI standards and connected devices change. If future access matters, ask whether the selected pathway makes cable replacement practical rather than permanently trapping a cable that may later need to be upgraded.
Option 3: a new recessed receptacle or other electrical work
Some rooms need a permanent receptacle behind the television rather than a plug-in relocation system. That may be the case when the existing outlet is poorly located, the proposed route does not fit a manufactured kit, or the broader project already includes electrical work.
Treat this as a separate scope item. Ask who is responsible for the electrical portion, what approval or permit may be required, and when it must be completed relative to the TV-mounting appointment. Do not assume that a standard mounting visit includes new branch-circuit wiring at every location.
Option 4: keep the route accessible through furniture
A media console, removable wall panel or purpose-built furniture channel can hide most of the view without burying the connections. This option is useful when game consoles, streaming devices or receivers change frequently, or when the homeowner wants easy access for troubleshooting.
Keep ventilation and connector access in the plan. Do not pack power supplies and equipment into a sealed space simply to hide them. Protect cords from sharp furniture edges, hinges and pinch points, and leave enough room to remove a device without pulling on the television’s ports.
Count every connection before selecting the route
Build the cable list from the finished experience. A television that streams over Wi-Fi may need only power, while another room may need HDMI for a receiver or console, Ethernet, antenna coax, a soundbar connection and a control cable. Photograph the TV ports and the planned device location so the route can be checked before installation.
Some televisions use a separate connection box. Samsung says the One Connect Box is available only with select models and cautions owners not to bend its cable sharply. Samsung also distinguishes the in-wall-rated One Connect cables that are available from a standard along-the-wall or baseboard route. Verify the exact television, box and cable rather than relying on the phrase “One Connect.”
Full-motion mounts add another variable. The cable bundle must reach the TV throughout the mount’s intended movement without becoming taut, pinched or caught in the arm. At the same time, excessive loose cable should not interfere with the bracket or hang into view.
- TV power and any separate connection-box power
- HDMI or eARC for soundbar, receiver, console or media player
- Ethernet or antenna/coax where used
- USB, optical audio or control cables required by the actual devices
- Service slack and access for the mount’s full intended range
What to send before a cable-concealment appointment
A useful request shows the whole system, not only a close-up of dangling wires. Send a wide room photo, a straight-on wall photo, the exact television and mount models, the outlet location, the device list and a photo of the furniture or equipment location. Mention brick, stone, tile, plaster, paneling, a fireplace or any known renovation.
State the result you want—no visible cords, a paintable cover, easy device access, or a fully recessed look—without prescribing a method before the wall and equipment are assessed. Ask the provider to confirm the cable-management method, included components, electrical scope, current availability and written price for the address.
| Send this | Why it matters |
|---|
| Wide wall and room photos | Shows outlet, furniture, fireplace, windows and likely route |
| Exact TV and mount models | Reveals port positions, depth and movement |
| Every connected device | Determines cable count, connector size and access needs |
| Existing cable labels or product links | Helps verify length and intended installation use |
| Wall and access notes | Flags masonry, managed-property rules or other constraints |
How QuickMountTV approaches the decision
QuickMountTV’s public cable-concealment page describes in-wall power relocation and AV routing for suitable drywall installations, while noting that solid brick, stone and some plaster walls may call for a paintable surface raceway instead. The correct method still depends on the actual wall, products, local requirements and appointment scope.
QuickMountTV™ owns and publishes this Journal, so its recommendation to book QuickMountTV is not independent. Homeowners can use this guide to compare any qualified provider. If you choose QuickMountTV, request a current written scope and price for the exact television, wall and cable list; do not rely on a national starting price or assume every method is available at every address.
Common questions
Can I run the TV’s ordinary power cord inside the wall?
Do not assume so. Use a finished power method designed and documented for that installation, follow the product instructions and local requirements, and use qualified electrical help when fixed wiring is involved.
Can any HDMI cable be hidden in a wall?
No. Verify the exact cable’s markings and manufacturer documentation for the planned in-wall use, plus any local requirements. Plan a replaceable path when future cable changes are likely.
Does a surface raceway look professional?
It can. A straight, correctly sized cover that meets the TV and furniture cleanly and is painted to match the wall is a practical finished solution, especially where in-wall routing is unsuitable.
Can a Samsung One Connect cable go in the wall?
Only use a model-compatible cable that Samsung identifies for in-wall installation and follow local guidelines. Samsung’s standard guidance also describes routing along a wall or baseboard and warns against sharp bends.
Can wires be concealed with a full-motion mount?
Yes, when the route, connector access and service slack are planned for the mount’s full intended movement. The cable bundle must not become taut, pinched or trapped in the arm.
