CONNECT YOUR COMPUTER TO YOUR TV
1. Look at the back of your computer for a monitor connection. It should be a 15-pin VGA output, a DVI connection or an S-Video output. If you’re unsure, check the video section of your computer’s user manual.
2. Check your TV connections. If you own an analog set, look for an S-Video input. Most digital TVs have a VGA input.
3. For analog TVs, use an S-Video cable and a 1/8-inch left/right RCA cable for sound to connect to the computer. If your computer has only VGA, you should use a VGA-to-S-Video adaptor. For digital TVs, use a 15-pin VGA cable and a 1/8-inch left/right cable.
