How to Use Cat 5 Cable to Run HD Video & Audio

Updated February 21, 2017

Cat 5 cable, also known as Category 5 cable, is well-suited for transmitting high-definition video and audio from a device to a TV at a distance of more than 50 feet. To use a Cat 5 cable as an audio/video cable, add a Cat 5 transmitter/receiver kit. The kit converts the signals from a HD source device into a format that can be transferred through the Cat 5 cable. This gives you the ability to send HD video and audio at distances of 50 feet and greater---something that difficult to do with conventional video and audio cables.

Place the Cat 5 transmitter next to the video source device, for example, a Blu-ray player. Plug one end of a HDMI cable that transfers HD video and audio into the HDMI input on the Blu-ray player. Plug the other end of the HDMI cable into the HDMI input on the Cat 5 transmitter. Plug the power cord of the included power supply into the Cat 5 transmitter and the AC plug into a wall socket for power.

Place the Cat 5 transmitter next to the video device that will display the HD video and audio, for example, a high-definition TV. Plug one end of a HDMI cable into the HDMI output on the Cat 5 receiver. Plug the other end of the HDMI cable into the HDMI input on the HDTV. Plug the power cord of the included power supply into the Cat 5 transmitter and the AC plug into a wall socket for power.

Screw one end of the 100 foot Cat 5 cable into the coax output on the Cat 5 transmitter. Screw the other end of the Cat 5 cable into the coax input on the Cat 5 receiver.

Turn the HDTV on with its remote. Press the "Menu" button. Select "Settings," then "Video," then "Video input." Select the proper HDMI input.

Tip

Component cables and audio cables can be attached to a Cat 5 transmitter/receiver kit that has the appropriate connectors for sending HD video and audio in the same manner as that of a HDMI cable.
