HDMI cables


HDMI has different connectors on the cables. Most are Type A on both ends like HDTV to HD cable box hookup. Camcorders can have the mini-HDMI connector, Type C on one end and Type A on the other end.

Type A

HDMI Type A connector has 19 pins, with bandwidth to support all SDTV and HDTV modes.

Type B

This connector has 29 pins and can carry double the video bandwidth of Type A, for use with very high-resolution future displays such as WQUXGA

Type C

A Mini connector defined in the HDMI 1.3 specification, it is intended for portable devices. It is smaller than the Type A plug connector but has the same 19-pin configuration. The Type C Mini connector can be connected to a Type A connector using a Type A-to-Type C cable.

Type D

A Micro connector defined in the HDMI 1.4 specification keeps the standard 19 pins of Types A and C but shrinks the connector size to something resembling a micro-USB connector.

Cable length

Although no maximum length for an HDMI cable is specified, signal attenuation dependent on the cable's construction quality and conducting materials limits usable lengths in practice.

Cable category

HDMI 1.3 defines two cable categories:
Category 1-certified cables, which have been tested at 74.5 MHz (which would include resolutions such as 720p60 and 1080i60), and Category 2-certified cables, which have been tested at 340 MHz (which would include resolutions such as 1080p60 and 2160p30).

Category 1 HDMI cables are to be marketed as "Standard" and Category 2 HDMI cables as "High Speed".

The Ultra High Speed HDMI® Cable

The latest HDMI Cable is the only cable that complies with stringent specifications designed to ensure support for all HDMI 2.1a features including uncompressed 8k@60 and 4K@120. The cable’s bandwidth supports up to 48Gbps, it is backwards compatible with existing HDMI devices, and features exceptionally low EMI which reduces interference with nearby wireless devices. For verification and authentication, the cable packaging is required to display the Ultra High Speed HDMI Certification Label which includes the Cable Name Logo printed on it.

What is HDMI with Ethernet?

HDMI with Ethernet allows a device that's connected to an Ethernet network to share the connection with other components over an HDMI cable equipped with Ethernet capabilities. These cables can carry data between the connected devices. Installation is simplified because a single cable does the job of what previously required two cables. Perhaps the most common application for HDMI with Ethernet is for use with a gaming console. Instead of having to run two separate Ethernet cables, one to an internet-capable display and one to the gaming console, the connection is shared by the two components connected by the HDMI with Ethernet cable. Note that both of the devices in the installation must support HDMI with Ethernet for this to work. These devices will be labeled as HDMI Ethernet Channel (HEC) compatible. A high-speed HDMI with Ethernet cable will be backward compatible, future-proofing your installation for any new devices, even if your current setup lacks HEC capabilities.

Audio Return Channel (ARC) and
Enhanced Audio Return Channel (eARC)


One of your TV's HDMI ports might be labeled ARC or eARC. Audio Return Channel (ARC) enables a TV to use the same cable transmitting the HDMI signal to the TV to “return” the audio signal to a sound bar or AV receiver. That means fewer cables in your setup and you can use your TV's remote to control volume levels. It also provides the ability to transmit Dolby TrueHD or DTS HD Master Audio to your sound bar or receiver. An HDMI cable that supports 4K resolutions will support ARC. Enhanced Audio Return Channel (eARC) is a feature of HDMI 2.1. It supports full-resolution audio signals, meaning it supports Dolby Atmos and other uncompressed sound formats. If your components support eARC, use a high-speed HDMI cable with Ethernet.
