A Beginners Guide to HDMI Cables – Which to Buy and How Much to Pay?

While HDMI cables were designed to simplify the process of connecting the various devices that make up your home theatre system, the simple fact is that many people are totally confused about what HDMI cables actually do; why some cables are so much more expensive than others, and why there are different versions of HDMI.

What Is HDMI?

HDMI or ‘High Definition Multimedia Interface’ is a type of connection widely used in devices, such as HD TVs, satellite boxes and Blu-ray players. HDMI cables carry both audio and video signals, so instead of having to use several runs of cable you now only need a single cable in order to make a connection between your devices.

  • Type B was developed for professional use in the motion picture and broadcasting industry. Type B cables have a slightly different size of plug, and use 29 pins,

Does Size Matter?

As with most cables, the length of the run does have a slight affect on performance. HDMI cables generally deliver the best results with runs up to 15 feet in length. If you use a longer cable the difference in performance is so small that you probably won’t notice, but it’s something to bear in mind if you plan on running a HDMI cable the entire length of your house.

How Much Should You Pay?

The common misconception is that the most expensive HDMI cables deliver the best performance. This simply is not true! All HDMI cables use the same basic technology to carry the audio and video signals, so it’s incredibly hard to spot the difference in performance between cables with a $100 price tag, and cables with a $25 price tag. While you should try to avoid cables that are obviously under priced – these cables tend to be made to a low standard – you should also be cautious of paying large amounts of money just for fancy packaging or a named brand.
