How to Convert a Flat Screen Computer Monitor for Use As a TV

If you recently purchased a new computer with a monitor, you may be wondering what to do with the old one. You could set up a dual monitor system or even donate the old monitor to charity. However, turning the old flat screen into a new television is also a practical alternative.

To convert your old monitor into a TV, you do not need a computer. All you need is an external TV tuner and a couple of cables. It is not difficult to convert the old monitor for use as a TV, and the task should take you less than an hour.

Things You'll Need

  • Flat screen computer monitor
  • Analog external TV tuner
  • VGA Cable
  • Computer speakers (if monitor does not have built in speakers)
  • S-Video, Composite or R/F coaxial video cable
  • RCA sound cable (red/white)


    • 1

      Place the monitor and the external TV tuner in the location where you will view the monitor/television.

    • 2

      Connect the video output from the cable/satellite box to the external TV tuner's video input (use the S-Video, Composite or R/F coaxial video cable). Alternatively, you can connect the R/F coaxial cable connection directly to the external TV tuner's coaxial cable port.

    • 3

      Plug the red and white RCA cables into the audio output jacks of the cable/satellite box and the audio input jacks of the external TV tuner.

    • 4

      Plug the monitor's VGA cable into the external TV tuner's VGA output port.

    • 5

      Connect the cable from the monitor's built-in speakers into the external TV tuner's audio output jacks. If the monitor does not have built-in speakers, connect a pair of external multimedia speakers to the external TV tuner.

    • 6

      Plug in all devices into available electrical outlets. Power-on all the devices and use the remote control for the external TV tuner to select a video source. Use the remote control for the external TV tuner or the remote for the cable/satellite box to change channels on your new TV.

Tips & Warnings

  • You can connect a VCR, DVD player or even video games to the analog external TV tuner and enjoy them on the newly converted monitor.
