Best Way To Run HDMI Cable Through Wall

Here is the Best Way To Run HDMI Cable Through Wall. I didn’t even realize that this was a hot topic until the Christmas season. Several family members purchased new flat-screen televisions and were looking for the best way to achieve the “clean appearance” that a wall mounts display with no cables visible.

Because the majority of us with new flat screens do not have homes built recently to be able to run the TV’s electricity, HDMI, RCA, and other cables on the wall.

They are tools you can use to stay ahead of the game:

  • Wire Fish Tape (or: Fish Tape, Wire Snake, Wall Snake, whatever you want to call these times).
  • Drywall Hand Saw
  • Sharpie Marker
  • Electrical Tape

Let’s discuss the equipment you’ll require:

  • Two (2) Wall Plates
  • Two (2) Existing Construction Gang Boxes
  • Cables [in my instance: two 15 feet. HDMI (1 for DirecTV another for HTPC), One RCA cable (goes from the TV to a surround-sound receiver), One television power cable (of course, it is included along with the television)[


  • Grab the Sharpie, set your Single Gang Wall Box against the wall, and trace the inside with your marker. This will give you the approximate dimensions of the hole you’re going to make in the wall.
  • Make sure you do this two times: one down by the baseboard and another higher on the wall mount of the TV bracket. Make sure the holes are straight in line with each other and are within the same stud area. In a problem, it is hard or even impossible to connect cables.
  • Get your hand saw for drywall and cut the rectangular holes. Wiggle the saw into there does not need to go any further than the surface (say approximately 1/8 inch). After cutting the rectangular shape, you can check whether the wall gang box will fit. It’s likely not, however, so you can perform some fine-tuning and trim the areas that require it.
  • Install the wall gang boxes into the holes. It is not necessary to tighten them up yet.
  • Wire the fish or snake cable through the hole at the top and down into the wall, then remove it through the hole in the bottom. It’s much more complicated than it sounds, so it’s best to have a helping hand. My experience is that using the “wire fish” tool is a must… We tested a wire hanger for clothes, but it didn’t work.
  • Once you have your fish wire dangling from the bottom hole, grab your cables and attach them onto the wire of your fishing in a way that will make the wires “aerodynamic” but not large. Keep in mind that you’re pulling the wires through walls that have insulation, another wiring, or whatever else is in. Your cable bundle needs to be as clean as possible to avoid getting in the way of other cables when you take it out.
  • Then, have your assistant pull the cables upwards from the bottom while you pull the fish wire from above.
  • After you have the wires running, make sure that you’ve got each of them. I had completed the entire task before realizing I didn’t have the TV’s power cord!
  • Take your screwdrivers out, and then turn the screws inside the gang box until the small “arms” are firmly pressed against the wall’s back.
  • The cables should be threaded through the holes in the faceplates that pass through (or connect them to an individual faceplate if you purchased one).
  • Use the screws to connect them to the boxes for gangs.

For instance, if you need to conceal the HDMI cable from your television in your living space, you can prepare to work more quickly. But, that doesn’t mean that you can’t make things to do, such as finding the power cables and studs on the wall you’ll put in the cable.
