Hide TV Cables Behind Your Wall

A wall-mounted TV transforms a living room, but the bundle of cables dangling down the wall destroys the effect. The impulse is to ignore it or drape them behind furniture, but there's a proper fix that takes less than two hours and costs about thirty dollars. An in-wall cable management system creates a legal, safe pathway inside the wall cavity, keeping power separate from low-voltage cables and bringing everything to code. The job breaks into three parts: locating studs and planning the route, cutting access holes and fishing the pathway, then mounting plates and running cables. Most walls are open cavity construction, meaning there's usually a clear run between the TV location and the outlet below. You'll install two gangbox-style recessed plates, one behind the TV and one near your components, with a flexible conduit connecting them inside the wall. The result looks built-in, passes inspection if you ever sell, and makes switching gear or adding cables trivial.

1. Map Your Cable Route. Use a stud finder to locate studs on both sides of where your TV will mount. Mark a point centered between studs, about four inches below where the TV will hang. Mark a second point directly below it, about twelve inches above the baseboard, also centered between the same studs. Hold a level vertically between marks to confirm they're plumb and the pathway won't cross a stud.
2. Open the Upper Pathway. Place the upper mounting plate against the wall at your top mark and trace its outline. Use a drywall saw to cut along the traced line, angling the blade slightly outward so the cutout piece is larger than the hole. Save the cutout — if you hit something unexpected, you can patch it. Peer inside with a flashlight to confirm the cavity is clear down to the lower mark.
3. Clear the Lower Opening. Trace and cut the lower hole using the same technique. Check that you can see light from the upper hole when looking up from the lower opening. If insulation blocks the view, pull it aside gently. This confirms your cable pathway is clear.
4. Snake the Conduit Through. Thread the flexible tube from your cable management kit down through the upper hole. Let gravity pull it down while guiding it from below. When the end emerges from the lower hole, pull through about six extra inches. The tube should hang slack inside the wall, not stretched tight, to allow cables to move freely.
5. Seat the Upper Box. Install the upper recessed box according to kit instructions, feeding the conduit through its back opening. The box should sit flush with the wall surface. Attach its faceplate with the power inlet and cable pass-throughs. Plug in the power jumper cable that came with the kit — this connects to your TV and is the only cord that will show.
6. Mount the Lower Outlet. Feed the conduit through the lower box and mount it flush to the wall. Install its faceplate with cable exit ports. The power cable from this box will plug into your existing wall outlet. Run this cable and verify you have power at the upper box before proceeding.
7. Thread Cables Carefully. Feed HDMI, streaming device power, and any other cables through the conduit from top to bottom. Work one cable at a time. Label each cable end with tape before feeding it through so you know what's what when they emerge. Leave a service loop of about eight inches at each end coiled inside the wall box.
8. Verify Power and Picture. Plug the upper power jumper into your TV. Connect all cables to their devices above and below. Power everything on and verify each input works. Cable-manage the lower connections with velcro straps so they stay organized inside or behind your media console. The wall should now show only the single short power jumper behind the TV.
