Step 1: Plan Your Installation

Before starting the installation process, take some time to plan your setup. Consider the location of your devices (e.g., TV, gaming console, Blu-ray player), seating arrangements, and any potential obstacles such as power outlets or other cables. Determine the most convenient and aesthetically pleasing spot for your HDMI wall plate keystone, ensuring it is within reach of your devices and easily accessible for future adjustments.

Step 2: Choose the Right HDMI Wall Plate

Select an HDMI wall plate keystone that suits your needs and preferences. There are various types available, including single-gang plates for one HDMI connection, double-gang plates for multiple connections, and angled plates for tight spaces. Additionally, consider factors such as color, material, compatibility with your existing wall plates or decor, and any additional features like Ethernet or USB ports.

Step 3: Locate and Mark the Installation Point

Use a stud finder to locate the studs in your walls and identify a suitable spot for your HDMI wall plate keystone that avoids drilling into studs. Mark the center of the hole for the wall plate using a pencil, ensuring accurate measurements and double-checking your markings. If necessary, use a level to ensure the mark is straight.

Step 4: Check for Hidden Utilities

Before drilling, it’s crucial to check for any hidden utilities like electrical wires, plumbing, or gas lines. You can do this by contacting your local utility companies or using a non-contact voltage detector. This step is vital for safety and preventing potential damage to your home.

Step 5: Drill the Hole for the Wall Plate

With the hole marked and utilities checked, put on your safety goggles, gloves, and dust mask. Use a drill and a hole saw or paddle bit that matches the size of your HDMI wall plate to carefully cut the opening in the wall. Be cautious not to damage any electrical wires or pipes behind the wall. If you encounter resistance while drilling, stop immediately to avoid potential hazards.

Step 6: Install the Keystone Jack

Take the HDMI wall plate keystone and gently insert the keystone jack into the opening in the wall plate. If your keystone jack does not come pre-installed, you may need to use a keystone jack removal tool to help press it into place. Ensure the keystone is securely seated and flush with the wall plate.

Step 7: Prepare the HDMI Cable

Strip the outer insulation of your HDMI cable to expose about 1 inch of the inner wires. Be careful not to damage the delicate wires inside. Using wire strippers, remove approximately 1/4 inch of the insulation from each of the individual wires (usually 19 pins).

Step 8: Connect the HDMI Cable to the Keystone Jack

Carefully align the exposed wires of the HDMI cable with the corresponding pins inside the keystone jack. Gently press each wire into its respective pin until it clicks into place. Once all wires are connected, use electrical tape to secure the wires to the back of the keystone jack, ensuring a neat and tidy finish.

Step 9: Run the HDMI Cable to Your Devices

If you haven’t already done so, run the HDMI cable from the wall plate location to your devices. To facilitate this process, you may find it helpful to use a fish tape to guide the cable through the wall cavity. Ensure that the cable is routed safely and securely, avoiding any sharp edges or pinch points. Use cable ties or Velcro straps to manage excess cable length and prevent tangling.

Step 10: Conceal Cables and Manage Wires

For a clean and professional appearance, consider concealing the HDMI cable and other wires using cable conduits, raceways, or wire moldings. These solutions can be painted to match your walls and help blend them seamlessly into your room’s decor.

Step 11: Connect the HDMI Cable to Your Devices

Attach the HDMI cable to your devices, making sure to firmly seat the connectors and lock them in place if applicable. Power on your devices and test the HDMI connection to ensure that video and audio are functioning correctly.

Step 12: Mount the HDMI Wall Plate

With the HDMI cable connected and functioning properly, it’s time to mount the wall plate to the wall. Align the holes in the wall plate with the ones you drilled earlier, and insert screws through the plate into the wall. If your wall is made of drywall without studs, use a wall anchor kit to ensure a secure attachment.

Step 13: Touch-Up and Finishing

Inspect the area around the installed HDMI wall plate keystone for any rough edges or damage caused during the installation process. Sand down any rough spots and use a drywall patching kit if necessary. Once the area is smooth and even, paint or touch up the wall to match your existing decor.

Step 14: Organize and Label Cables

For easy identification and maintenance, consider labeling your HDMI cables and organizing them with cable ties or Velcro straps. This will make it simpler to locate and troubleshoot issues in the future.

Step 15: Maintain and Upgrade Your Setup

Periodically inspect your HDMI wall plate keystone and cables for signs of wear and tear, and address any issues promptly. As technology advances, you may want to upgrade your HDMI cables or wall plate to accommodate newer features or higher bandwidth capabilities.


Installing an HDMI wall plate keystone in your home theater is a straightforward process that can greatly enhance the functionality and aesthetics of your entertainment system. By following these detailed steps and considering the provided tips and considerations, you can achieve a professional-looking and well-organized setup that will serve you well for years to come. Remember to prioritize safety throughout the installation process and consult professional assistance if needed. Regular maintenance and upgrades will help keep your home theater system performing at its best.
