HDMI is quick becoming the interface of choice for a wide variety of home entertainment devices. You will find HDMI sockets on loads of LCD and plasma TVs, projectors, DVD recorders and players and home theater systems.

What is HDMI?

Lacking going into the technical fine points, the High Definition Multimedia Interface simply allows the transmission of both video and audio in a digital, rather than analogue, fashion. It is somewhat akin to the DVI interface you may be familiar with which is found on loads of computers and set-top boxes, but DVI can single carry video signals. You can though straightforwardly buy a DVI to HDMI converter, for model to join an LCD TV to your computer for a high quality digital show.

The Benefits of HDMI

With older interfaces, such as SCART and component video, extra steps are caught up in translating signals between analogue and digital formats; each time this happens the signal is degraded. HDMI solves this problem by transmitting an uncompressed digital signal, improving quality and dependability. It supports the latest 1080p high definition video standards, as well as being backwards-compatible with lower resolution standards. It also allows for high quality digital audio finished as loads of as 8 channels, all on the same cable. The ease with which you can now join your audio and video devices is greatly augmented. As you no longer need separate leads for audio and video, cable management is much simpler. Also, HDMI has much greater bandwidth than that needed for any mainstream audio or video contrivance currently on the market, for that wits it’s ‘future-proof’

What Category of Cable Should I Buy?

With HDMI cables unreliable in price from under $10 to $50 or more, you may wonder what the difference is between the multitude of cables on the market. The answer is not very much. A salesperson may tell you that their premium cable with gold-plated connectors and specially thick wiring is superior to cheaper offerings, but this is fundamentally untrue. Don’t be seduced by sales talk and gimmicks. As the cable is single transmitting digital signals — 1′s and 0′s — it will either work or it won’t, there’s no halfway household. It’s not possible to get a ‘better’ signal by using a special coating on the plug or different wire.

If you’re in the administer of setting up your home entertainment devices, then you would be well advised to opt for cheap HDMI cables and spend the money you will save on other parts of the system.
