How to Connect a Computer to a TV With a Coaxial Cable


Connecting your television to your computer will allow you to utilize the screen as your monitor, easing eyestrain from having to read small characters on a tiny computer screen all day long. While newer televisions have connections specifically designed for PC input, older TVs often do not--they normally possess nothing more than a coaxial connection on the back of the machine. With the right equipment, it is still possible to attach even the oldest television to your computer using a coaxial connection.

Things You'll Need

  • Coaxial cable
  • Coaxial-ready video card
  • Phillips screwdriver
  • Remove the side of your computer case to install the video card. The most common method of doing this is to remove the screws on the rear right hand side of your machine, but this can vary so consult your instruction manual if you have difficulty removing the case.

  • Install the card into the AGP or PCI-E slot. Consult your computer's operating guide to determine which of these slots is present on your machine. They are typically located on the lower half of the motherboard in horizontally aligned slots that line up with the holes in the back of the case. Simply push the card down into the slot until it locks into place then screw it in with the included screw.

  • Attach one end of the coaxial cable to the coaxial port in your new video card and the other to the back of your television.

  • Start up your computer. The computer will auto-detect the television as the monitor, displaying the loading screens for your operating system as the computer boots up.

  • Install the drivers that came with your new video card by placing the CD in the drive and following the on-screen instructions to complete the installation process.
