HDMI cables are used to connect high-definition audio/visual devices, such as Blu-ray players and video game systems, to televisions. These cables connect to the devices through the use of an HDMI connector. Inside this connector are small wires that serve as the leads for the HDMI cable.
Use your box cutter to cut through the HDMI cable, roughly 2 inches below the HDMI connector.
Insert the cut cable into the wire stripper and cut through the black outer covering of the cable. Use your hand to pull the cable away from the leads.
Separate the leads from each other, making sure they are uncrossed, and peel the plastic wrapper and aluminium foil from the four twisted pairs in the group of leads.
Repeat the process with the other side of the cable. You now have an HDMI cable with two sets of exposed leads.
