HDMI Cable Central
Everything you need to know about HDMI cables, from quality and construction to versions and features.
HDMI, or High Definition Multimedia Interface, is the current standard for high definition video. Capable of carrying high definition video, surround sound audio, EDID handshaking signals, Ethernet and IR signals via a single cable, HDMI has solidified its standing as the industry standard for easy and efficient high definition video runs.
Available from Sewell Direct - The very latest in HDMI technology

Why is HDMI better?
Older signal formats like RCA, VGA, or DVI all suffer from technical or convenience issues that leave HDMI the clearly superior format. The maximum resolution for RCA is 480i, while HDMI can carry a full 1080p signal. DVI can carry 1080p as well, but it doesn’t include an audio channel. You are forced to run either an extra 3.5mm audio cable for simple stereo sound or a fragile SPDIF cable for surround sound.
HDMI combines and surpasses the specs from multiple previous video formats, capable of carrying full 3D 1080p signal and 7.1 Dolby digital surround sound in a single sturdy cable. It also has an EDID handshaking channel which means that source devices are able to interface with display devices in a way that analog signal formats can’t. This allows your source device to custom tailor its signal content for the receiving device, cutting down on incompatibilities and facilitating ease of use.
How do I use HDMI?
Like most video formats HDMI is as simple as plugging it in and letting it run! All you’ll need is an HDMI source device and a display with an available HDMI port. Just plug one into the other with a single HDMI cable and watch high definition video with crisp surround sound to your hearts content!
If you don’t have an HDMI port on your source device we have a number of converters available to change signal types from the older style signals to HDMI.
Quality is a factor
There are many different types of HDMI cables, at different prices and different qualities. You don't have to overspend for a quality HDMI cable, but you should take a couple things into consideration. Where is this cable going to be used? If your cable is going to be run behind walls, stretched, pulled, or possibly kinked- look for a durable cable with a strong outer coating. The Sewell Premium line of HDMI cables feature 5 layers of protection for all varieties of cables stress.
Length is a factor
The further an HDMI signal has to travel across a cable the more that signal will deteriorate, giving you a loss in quality. The HDMI standard for maximum length is 15 feet. This doesn't mean you can't go longer, it just means you start running the risk of losing some picture quality when you attempt using longer lengths of cable. To ensure you have a strong HDMI signal, especially over more than 40 feet of cable, we recommend using an HDMI repeater. An HDMI repeater features an HDMI input and an HDMI output, regenerating the incoming HDMI signal before outputting it through the next cable. This will guarantee a strong HDMI signal across long connections.
Frequently asked questions
Q: I seem to remember something about 1.3b or 1.4 HDMI cables. What happened to those naming conventions?
A: HDMI Licensing LLC, the company responsible for regulating the HDMI standard, is encouraging retailers to drop the old HDMI tiered rating system. The difference between an old 1.3b cable and a 1.4 cable is technical and confusing although the cables will do largely the same thing. Instead resellers are encouraged to list the specifications for our cables. Our HDMI cables are full 3D compatible with an Ethernet channel and can carry 1080p signal plus 7.1 surround sound.
Q: Your prices are amazing! What allows you to sell these for so much less than a brick and mortar retailer?
A: Since we manufacture our own name brand cables we are able to control the quality and the cost, keeping the former high and the latter low. Since HDMI is a relatively new format and knowledge of competitive pricing is low most brick and mortar resellers capitalize on that rift to mark up their cables. Our cables adhere to the exact same HDMI standards but are much, much more competitively priced.
