Connecting a TV to a computer tower makes it possible to enjoy website content and other multimedia accessible from the computer on the television screen. Most TVs and computers are equipped with a variety of jacks for hooking up different types of equipment. Adaptors are also available if the two components each have completely different jacks from the other. The most common connection on a TV and a computer is an S-video jack. Check the back of both components to determine the best cable to buy before heading to the store.

Instructions

    Using the Same Connection Type

  1. 1

    Check the back of the computer tower and the TV for compatible connections. An S-video jack is round, with four holes in the centre and three notches around the perimeter. If both the TV and PC have S-video jacks, use an S-video cable.

  2. 2

    Plug an S-video cable from the computer to the TV, aligning the four pins in each plug with the four holes in each jack.

  3. 3

    Connect the mini-plug on the Y-adaptor to the Line OUT jack on the back of the computer tower, or plug into the headphone jack on a laptop.

  4. 4

    Insert the plugs on one end of the audio cables into the two Y-adaptor jacks. Connect the plugs on the other end to the audio IN jacks on the TV.

    Connect with an Adapter

  1. 1

    Use the computer's Video Graphics Array (VGA) jack if it is not equipped with S-video. The four-sided VGA jack contains 15 holes arranged in three rows to match with the 15 metal pins in a VGA plug. Buy an S-video to VGA adaptor at a computer or electronics store to convert the PC's VGA jack into an S-video connection for the TV.

  2. 2

    Connect one end of the VGA cable to the VGA port on the back of the computer tower and turn the lock bolt clockwise on each side of the VGA plug to secure the connection.

  3. 3

    Connect the plug on the other end to the VGA to S-video adaptor.

  4. 4

    Plug in the S-video cable to the jack on the adaptor and the other end to the S-video jack on the back of the TV.

  5. 5

    Connect the mini-plug on the Y-adaptor to the Line OUT jack on the back of the computer tower, or plug into the headphone jack on a laptop. Insert the plugs on one end of the audio cables into the two Y-adaptor jacks, then connect the plugs on the other end to the audio IN jacks on the TV.

Tips and warnings

  • Unplug the TV and shut down the computer while connecting the equipment.
