While you can use different types of cables to link your equipment when building a home theatre, choosing HDMI cables comes with many advantages, which are difficult to ignore. The HDMI cables carry digital audio and video, allowing for the highest resolution images and sound to be supported, and they are the cables that you would want to use if you want to get the best out of your equipment. The HDMI cables are now at version 1.4, where the 1.3 and 1.4 are the only Category 2 cables; the Category 2 specification supports including 1080p resolution and virtually all PC and TV video formats.
When buying an HDMI cable, the price does matter, but you are not required to buy the most expensive one in order to get perfect quality video and audio. In fact, you can find good quality cables from as little as twenty pounds, which cables should work for almost all setups. The cheapest cables cost around two to five pounds, but most of them are built from low quality material and they are not likely to be as durable as the higher-grade ones. Many manufacturers and retailers are pushing cables that cost hundreds of pounds, but these cables are unlikely to outperform the more affordable ones. There are only some specific instances when you might need a higher end HDMI cable and these are the cases when you would need in-wall installation or when you need a cable, which is longer than fifteen meters.
Before you purchase an HDMI cable, you need to make sure that all your equipment is HDMI-ready. If you have purchased the latest models Blu-ray Disk Player, DVD player, or HDVT, then they are likely to be HDMI equipped, but some older devices might not support HDMI and you might have to use different cables or adapters. If you need Audio return channel (ARC), which allows sound to be passed from the TV back to the home sound system, then you would have to purchase 1.4 version since they are the only cables that support ARC. They are also the only cables with Ethernet channel, but at the time of this writing, there is no equipment on the market, which uses the Ethernet channel. However, the 1.4 HDMI cables are ready to meet some future specifications and if you purchase one now, you are likely to use it with all video sources and displays that will be released in the near future.
