How to Display Your Computer Screen on a TV

By Techwalla Computers Editor

You can display your computer screen on a TV if your video card and PC have a TV-out port. Here's how:

Things You'll Need

  • A composite video cable
  • Video-out cable

Step 1

Turn off your computer and TV and disconnect the power supply for each.

Step 2

Connect your video card's S-video port to the TV's S-video port. If your TV does not have an S-video port, connect your video card's S-video port to the composite video-in port of your TV through a video-out cable and a composite video cable.

Step 3

Switch on your computer.

Step 4

Go to your operating system's control panel.

Step 5

Double-click on the "Display" icon and open the "Display Properties" window.

Step 6

Click on the "Output Device" tab. If you can't see this tab, go to "Settings" and click "Advanced." Then, select the "TV" tab.

Step 7

Enable video on TV by clicking on the "Enable Output to TV" button or "Output Device: TV." Your computer screen will go blank. Retain that setting. You can now use your TV as your computer's monitor.

Tips & Warnings

  • Some TVs have a VGA cord and port. In such cases, you can simply remove the VGA cord from your computer's monitor and connect it to the TV.
