Cables can make any room look messy, especially if they run across the floor or hang down from your TV or computer. If you want a super clean look, running cables behind a wall is the best way to hide them. This guide will show you, step by step, how to run an HDMI monitor cable, an AC power cable, or any other wire behind your wall in a way that’s safe and easy to understand.
Messy cables are not just ugly. They collect dust, get tangled, and can even trip people. If you have pets or small kids, loose wires can be dangerous. Hiding cables behind a wall keeps your space neat, safe, and stylish.
You can run many types of cables behind a wall, like:
HDMI monitor cable for your computer or TV
Internet cables (Ethernet)
Audio and video cables
: You should not run regular AC power cables or extension cords behind a wall. Only special in-wall rated power cables or permanent wiring should go inside walls for safety reasons. If you need power behind your TV or computer, the best way is to install a new outlet with the help of an adult or electrician.
To run cables behind a wall, first mark where you want the cables to enter and exit. Cut small holes in the drywall at these spots. Use a fish tape or a straightened coat hanger to pull your HDMI monitor cable or other wires through the wall from one hole to the other. Attach wall plates to cover the holes for a neat finish. Only use in-wall rated cables for safety, especially for anything carrying power.

1.
Decide where you want your cables to go. Use a pencil to mark the wall where you want the cable to enter and exit. Use a measuring tape to make sure the holes line up.
2.
Use a stud finder to locate the wooden studs inside your wall. You want to avoid cutting into these. Mark the edges of the studs so you know where to cut.
3.
Use a drywall saw to cut small holes at your entry and exit points. Make the holes just big enough for your wall plates. Be careful not to cut into any wires or pipes hidden in the wall.
4.
Sometimes there are horizontal blocks (called noggins or fire blocks) inside the wall. If you hit one, you may need to drill a small hole through it or adjust your cable path. Always check for hidden pipes or wires before drilling.
5.
Push the fish tape or straightened coat hanger through the top hole until it comes out the bottom hole. If you have insulation in the wall, you might need to wiggle it a bit or use a magnet to guide the wire.
6.
Tape the end of your HDMI monitor cable or other wire to the fish tape or hanger. Make sure it’s secure and smooth, so it won’t get stuck.
7.
Slowly pull the fish tape or hanger back through the wall, bringing the cable with it. Go slowly and gently to avoid damaging the cable.
8.
Once the cable is through, attach low voltage wall plates or brush plates to the holes. These make the job look neat and keep the cables from getting damaged.
9.
Plug your HDMI monitor cable into your computer or TV. If you ran an Ethernet or audio cable, connect those too. If you need power, use a properly installed outlet, not a regular AC power cable through the wall.
Use an in-wall rated HDMI monitor cable for safety and best performance.
Avoid sharp bends or pulling too hard on the cable.
Leave a little extra cable at each end so you can move your devices if needed.
Never run a standard AC power cable or extension cord behind a wall. It’s not safe and goes against safety codes.
If you need to hide power, use an in-wall power kit or have an adult install a new outlet behind your TV or computer.
If you have more than one cable, bundle them together with Velcro straps or cable sleeves. Run them through the wall at the same time to save effort. Use a wide enough wall plate to fit all your cables.
Paint your wall plates to match your wall color.
Use brush plates for a modern, tidy look.
Label each cable at the end so you always know which is which.
Don’t cut into studs or hidden pipes.
Don’t use regular power cords in the wall.
Don’t make holes bigger than you need.
Don’t pull cables too hard or bend them sharply.
Always ask an adult for help if you’re not sure what’s inside your wall. If you need to add a new outlet, get help from a grown-up or a licensed electrician. Safety is more important than speed!
Check your cables every few months. Make sure they’re not damaged or loose. Keeping cables neat and safe helps your electronics last longer.
