1. HDMI cable (preferably CL2 or in-wall rated for safety)

2.Fish tape or wire puller

3.Wall plates with HDMI ports


5.Drill with a long, flexible drill bit

Plan the Cable Route

Begin by planning the route for your HDMI cable. Identify the starting and ending points for the cable and determine the best path to run it through the wall. Avoid electrical wires, plumbing, and potential obstacles. Use a stud finder to locate studs and plan your route accordingly.

Choose the Right Cable

Select an HDMI cable that’s appropriate for in-wall installation. CL2 or in-wall rated cables are designed to comply with building codes and ensure safety within walls. These cables have fire-resistant jackets that reduce the risk of fire hazards.

Measure and Mark

Measure the distance between the HDMI source (e.g., AV receiver, game console) and the display (TV or projector). Mark the points on the wall where you’ll be drilling holes for cable entry and exit. Use a level to ensure accuracy.

Drill the Holes

Drill a hole at the starting point and another at the ending point of the cable route. Use a long, flexible drill bit to make the process easier. 

Attach the HDMI Cable to the Fish Tape

How to Run HDMI Cable Through Wall

Attach the HDMI cable to a fish tape or wire puller. Secure it tightly using masking tape to prevent it from detaching while pulling it through the wall.

Thread the Cable Through the Wall

Insert the fish tape with the attached HDMI cable into the hole at the starting point. Carefully guide the fish tape through the wall cavity, using a gentle twisting motion to navigate around obstacles. Once the fish tape reaches the hole at the ending point, pull it out, bringing the HDMI cable with it.

Install Wall Plates

Attach wall plates with HDMI ports at both ends of the cable route. Wall plates provide a clean and organized look while allowing you to easily connect and disconnect your devices.

Connect and Test

Connect one end of the HDMI cable to your source device and the other end to your display. Power on the devices and check if the signal is successfully transmitted. Test various content formats (e.g., movies, games) to ensure the cable is functioning properly.

Conceal the Cable

To achieve a seamless appearance, consider using cable management solutions such as cable raceways, paintable cord covers, or in-wall cable management kits. These options help conceal the cable and maintain a neat look.

Safety Precautions

When working with power tools, cables, and walls, safety is paramount. Be cautious when drilling holes and avoid damaging electrical wiring or plumbing. Turn off the power to any electrical outlets near your work area to minimize risks.


Running HDMI cables through walls might seem like a daunting task, but with the right tools, materials, and a systematic approach, you can achieve a professional-looking installation. By following this step-by-step guide, you’ll not only enhance the aesthetics of your entertainment setup but also ensure the safety and functionality of your HDMI connections.
