People use the term "to wire" something loosely, but when it comes to connecting computers and other video equipment, you're not so much wiring in the true sense as you are making the right connections. When you connect a computer and a TV together it can be used to watch TV on your computer or to see your computer screen on the TV. Most people however, want to record something from their TV to their computer, which can be accomplished but it will be recorded in real time.

  1. 1

    Install a video card that has the input or output connection that matches with your TV's input and output connections. Open your computer case by unscrewing the access door. Unscrew your current video card and lift it out of the card slot. Put the new card in place and screw it into the case. Close the case and attach the monitor cable.

  2. 2

    Connect the cables from the video card to the TV. Connect the appropriate type cable from the video card's "out" to the TV's video input and vice versa. These cables may be RCA, HDMI or coaxial cable depending on what the card and TV use for connections.

  3. 3

    Install the software that came with the video card. The software should include software to capture video.

  4. 4

    Change the settings to watch the TV or computer. On the computer you can choose to show the computer on the TV if the video card has that capability by choosing the TV as a monitor. Right click on the desktop and choose "Screen resolution" and change the settings to show on the secondary monitor. Change the video input settings on your TV accordingly by hitting the input button on the TV remote.
