Understanding HDMI Cables

With all the mystery that surrounds high-definition television, some cable manufacturers take the opportunity to confuse customers into buying over-priced HDMI cables. The truth about HDMI cables is; you only need to buy the cable that fits the needs of your installation. Follow the guidelines below so you can make an informed cable buying decision.

HDMI specification numbers should not dictate your cable purchase. HDMI specifications were written for device manufacturers so the HDMI interface will support features becoming available to the market. All of our cables have been tested by an HDMI Authorized Testing Center (ATC) to meet the bandwidth required to support the features commonly requested by electronics consumers. It is important to note that using a different cable type will not add or even defeat features like 3D, Audio Return Channel or HDMI Ethernet Channel, the device must have been designed with particular features.

There are essentially four cable types that apply to the AV market; High Speed HDMI Cable with Ethernet, High Speed HDMI Cable, Standard HDMI Cable with Ethernet, and Standard HDMI Cable. Since all of these cables are backward compatible, we primarily offer the High Speed HDMI Cable with Ethernet so we can buy in larger volume and offer a lower price.

Of the characteristics that determine if an HDMI cable will function correctly at long lengths the most critical are; conductor size, shielding, and manufacturing tolerance. We have selected HDMI cable suppliers that use only high quality materials and proven manufacturing techniques to guarantee our HDMI cable selection will meet your needs.

If cables will be permanently installed within the walls of your house you will want to install CL2 rated HDMI cables. CL2 rated cables meet NFPA and UL specifications for in-wall cable installation. If you are not going to install the cable in the wall, we offer non-UL listed cables to save you money.

While on the subject of installing a cable in the walls, although active cables feature error correction for inherent loss associated with all copper cables, we often steer people away from this cable type. Any active circuit is vulnerable to electrical surges and spikes by any number of origins. If a cable has been permanently installed behind the wall it will be costly to replace.

The physical size of the HDMI interface can make installation difficult, especially with TVs mounted close to the wall. We offer cable and adapter solutions that help in tight installations. If the route between the source and TV is short we have Super-Slim HDMI cables. We also offer flat HDMI cables that really make installation easier. Keep in mind though, flat HDMI cables are not intended for installation underneath carpet.

There are three commonly used connector types from the HDMI specification. The Type A connector is the full-sized HDMI connector and is the most widely used. The Type C connector or HDMI Mini connector is a little smaller than Type A and is used for portable devices like camcorders. The Type D connector or HDMI Micro connector is less than half the size of the Type A connector and is used with video devices like mobile phones. We offer HDMI Mini and HDMI Micro to Type A cables for use with your portable devices.
