HDMI stands for “High-Definition Multimedia Interface”. HDMI cable transmits the highest resolution signal for both video and audio, including a variety of resolutions of 480i, 480p, 720p, 1080i, and 1080p. HDMI cable carries both video and audio, including 5.1 surround sound, on a single cable connection. If the broadband connection is fast and the entertainment system (TV or computer) has HDMI input, this cable will deliver the best overall experience.

A growing number of products use an HDMI cable to achieve a high-clarity multimedia experience. A few examples of these products include computers, video cameras, smartphones, high-definition TVs, DVD players, and HD-DVD players.


The different types of HDMI cables include:

The standard HDMI cable, which has a similar connection for input and output, is used for a classic multimedia experience. It transmits resolutions up to 1080i or 720p.The HDMI cable with Ethernet maximizes resolution to 3840 x2160p and is most commonly used in digital theaters.

The HDMI Ethernet channel allows for an Ethernet connection between two HDMI-compliant devices, creating an internet connection.

The HDMI mini/micro cable is used with smaller devices including smartphones and small video cameras to accommodate their smaller inputs.


HDMI cables come in different thicknesses (measured in AWG). The AWG standard defines the thickness of the HDMI cable and how long the cable can carry information without losing the signal. The lower the AWG number, the better the connection. But keep in mind that higher AWG may provide similar clarity depending on the length it needs to carry the data.

Like everything else, the longevity of HDMI cable depends on maintenance. To prolong its proper function, make sure the cable is properly connected on both ends; Put it away from the path of travel, so it is not stepped on and make sure it lays flat; use mild force when inserting and removing the cable; Do not tug too hard on it, to avoid breaking connections inside the wire; make sure to insert the cable in the correct orientation or the cable may be damaged; keep dust away from the HDMI cable.

Mini HDMI Cables
The Mini HDMI cable was designed for portable devices including cell phones, cameras, navigation systems, and high-definition camcorders. Most of these devices produce file formats or content that is compatible with a high-definition display device, such as an HD TV. The Mini HDMI Cables are designed with two different end sizes. On one end there is an input small enough to fit into the portable device, while on the other end is a standard HDMI input to fit into the TV or other device connected to the portable device.

Micro HDMI Cables
Another small-size input type available is the Micro HDMI cable. It serves the same needs as the Mini HDMI Cable, with a different shape at the small end of the cable. This cable design is needed to fit devices with a connection that is slightly smaller than the Mini HDMI. Like the Mini HDMI Cable, the Micro HDMI Cable allows users to connect their portable device to a larger device to display images and video. More so, the Micro HDMI Cable allows charging the portable device (whether it is a smartphone or a game console). Blackberries and most Samsung and LG phones have a Micro HDMI input.

To determine whether a device uses a Mini or Micro HDMI input, check the device’s instructions or look at the input itself and compare the two different shapes at the smaller ends of the cables.
See the product's instructions to determine if the device is HDMI compliant.
