How to Hide All the Wires Behind Your TV
That tangle of black cords hanging under a wall-mounted TV is the first thing people notice and the last thing anyone wants to look at. The good news: it's completely avoidable. The better news: doing it right takes one afternoon, not a renovation.
Homeowners across Naperville, Bolingbrook, and Plainfield ask us about this constantly. Here's how hiding TV wires actually works, what your options are, and where DIY attempts usually go wrong.
Why the Cords Show Up in the First Place
Most TVs get mounted first and wired second. The mount goes on the studs, the TV goes on the mount, and only then does someone realize the power cord, HDMI cable, and maybe an Ethernet line all have to go somewhere. So they hang.
A pro plans the cable path before the mount goes up. That single change is the difference between a wall that looks finished and one that looks like a weekend project that ran out of time.
Wall-mounted TVs also sit higher than most people expect, which makes any visible cord look longer and messier than it does on a stand. A two-story home with a vaulted family room makes it worse. Six feet of dangling cable reads as twelve.
Your Two Real Options
There are really two ways to hide TV wires. You run them inside the wall, or you cover them on the surface. Everything else is a variation of one of these.
In-wall is the cleanest and what we recommend for most home owners. Surface raceway, a slim channel you can paint to match the wall, makes sense for rentals, brick, block, or any wall you can't open up. Here's how they compare.
If you plan to stay in the house and you care how the room looks, go in-wall. Raceway is a fine compromise. It just isn't invisible, and it never will be.
What Actually Goes Inside the Wall
This is where DIY jobs get risky. Low-voltage cables like HDMI, Ethernet, and speaker wire need to be rated for in-wall use, and they need to be kept separate from line-voltage wiring. Running a standard power cord inside a wall is a fire hazard and against code.
Only a short cord runs from the TV to the outlet, and both are hidden behind the screen. Everything low-voltage goes through a matching pass-through plate below or beside the TV.
While the wall is open, it's the right moment to think about everything else that might connect to it. A soundbar, a streaming box, a wired network connection so the TV isn't fighting for WiFi. If you're considering in-wall speakers down the road, our comparison of in-ceiling speakers vs. a soundbar will help you decide before the drywall is patched.

How a Clean Install Actually Runs
The process is more methodical than most people expect. Nothing gets cut until the path is planned, and nothing gets closed up until every connection is tested.
Planning the path means finding studs, checking for obstructions like fire blocks and existing wiring, and deciding where the equipment will live. Cables get fished from the TV location down to a nearby cabinet or media closet, then terminated to plates. Testing comes last, and it matters. Finding a bad HDMI run after the wall is patched is an expensive way to learn.
Mistakes We Fix All the Time
The most common one is cutting into the wall before checking what's behind it. Studs, fire blocks, and electrical runs don't announce themselves. Second is using the wrong cable for the job, a cheap HDMI cable that works today and drops the picture at 4K next year. Third is forgetting the future: no spare conduit, no extra Ethernet drop, no way to add anything without opening the wall again.
A good install leaves you room to grow. One extra cable run costs almost nothing while the wall is open and a lot of trouble once it's closed.
