How to Use My TV as a Computer Screen


Although the technology utilized in conventional television sets and computer screens used to be worlds apart, the advent of LCD screens for computers and HDTV televisions means that computer monitor technology is now essentially interchangeable with television technology. This means that you will be able to use your existing television set as a computer monitor far easier than you could in the past. Your television will have a dedicated port for receipt of a computer signal, necessitating only the proper cable to interface.

Things You'll Need

  • DVI or VGA cable
  • Television operating manual
  • Search through the operating manual of your television for the proper connection for attaching your TV to a computer. This will typically be either a VGA or DVI connection, located on the bottom or the rear of your television set.

  • Attach your computer to your television by using either a VGA or a DVI cable (depending on your connection type). Plug one end of the cable into the back of your computer where your monitor would normally attach and the other into the VGA or DVI port on your television.

  • Set your television to accept a VGA or DVI signal by using the remote control and the "Input" button to toggle through available inputs for your particular set.

  • Reboot the computer to auto-detect the television as your monitor.

  • Set the resolution by right-clicking in empty space on your desktop then going to either the "Properties" or "Personalize" option. Go to the "Display Options" screen, then move the resolution slider all the way to the right, which will be the native resolution of your television. Press "OK" to complete the change.
