Understanding Those Strange Cables That Stick Out Of Your Television

When it comes to our televisions, most of us have no idea how the things actually manage to work. It’s some kind of miracle that involves satellites in outer space, seven remote controls, and Gran Denyer smiling like a five year old. The back of our television is a forest of cables. Wander in too far, and you’ll have strange experiences with late-night SBS films. But it’s worth trying to understand a little about our televisions. What does each cord do? Where should I plug in my blue ray player? When will Family Feud be taken off air?

Most of the time, we go through an agonizing process of trial and error, putting cables into holes based on the idea that maybe some of them are colour coordinated. Risking electrocution can be a fun way to spend your afternoon, but if Russian roulette is not your game, it’s worth understanding how to plug in and set up your television.

Let’s look at the different cables and their uses.

HDMI cables.

HDMI Cables

HDMI cables transmit the highest quality audio and visual that your television is capable of displaying. Most modern television equipment can be plugged in with HDMI cables if you choose to. You should use HDMI cables for equipment that supports high definition. If you have a television set-top box, you can use HDMI cables. They are also useful for blu-ray players, which project high definition images.

Composite cables.

Composite Cables

Composite cables carry standard definition audio and visual signals. The red and white plugs are for audio, whilst the yellow is for visual display. These cables are generally outdated, but most modern televisions have plugs for them so that you can still use old VHS players and gaming systems.

Component cables

Component Cables

Component cables split the visual signal into red, green and blue. The two other cables are for audio. Modern gaming systems and media players can be plugged in using component cables. Often, these players will have a custom port on the player end, and the standard five plugs on the television end.

DVI cables.

DVI Cable

DVI cables are usually used by computers for transmitting a visual signal. Many modern televisions have DVI ports so you can plug your computer into your TV. This will not trnsmit audio from your computer to your television. To do that, you will need to buy special cables that can be plugged into your computer’s headphone jack.

USB cables –

With downloaded content being so popular, televisions usually have USB ports. You can use these ports to connect a hard drive, or you can plug a USB drive directly into your TV. This allows you to play AVI files, or look at photos files and listen to audio files.

A rudimentary understanding of television audio and visual set up can help you out with small problems. But televisions are complex, and even if you get your set working it’s most likely that a professional could arrange a set up that gives you a better quality image. Paying for a professional to correct or install your system pays for itself in the long run because you get a much better image and audio.
