Introduction to HDMI

HDMI cable

HDMI, or High-Definition Multimedia Interface, is a proprietary audio/video interface. It is capable of transmitting both high-definition (HD) videos and audios between two electronic devices via a single cable.

Over the years, HDMI has rooted among the public enclaves. Being a single-cable solution to every consumer’s audio-visual needs, HDMI promotes guaranteed convenience. It eliminates the use of two separate cables for audio and video functions (like an audio jack and VGA, respectively).

You may not notice it but HDMI is the most commonly used cable in homes right now. It connects devices such as digital TV, DVD player, Blu-Ray player, Xbox, cable box, Playstation and AppleTV with the television. Audio equipment such as mixers, recording systems and speakers use this cable as well.

Modern laptops and PCs recently are designed to have ports compatible with HDMI cables. With this innovation, these devices can now be easily connected with projectors, commercial screens and multi-screen video walls. HDMI cables will definitely help revolutionize corporate and commercial sectors – education, business presentations, digital signages and retail displays, amongst other applications.


Types of HDMI Cables

Audio/video technologies are continually advancing and HDMI specifications are occasionally adjusted and revised to ensure optimal capability and performance. Various HDMI cable types exist in the market, each designed to meet a particular performance standard. With such variety, it can be frustrating when determining the best cable for certain displays.

Below is a guide to assist you in finding the correct cable for a variety of configurations. It will give you an overview of the cable types, their capabilities and how to differentiate them from each other. Furthermore, all HDMI cable products are required to be labeled with Cable Name Logos provided by HDMI Licensing Administrator Inc. To pick out the most suitable cable for their needs, consumers are recommended to look for these logos whenever purchasing.

Eight types of HDMI cables


Standard HDMI Cable

The Standard HDMI Cable is designed to handle most home applications. It is tested to reliably transmit 720p up to 1080i, which are High-Definition (HD) resolution. This cable does not transmit 1080p (also an HD resolution), Ultra-HD (UHD) (3840×2160) and 4K (4096×2160) resolutions. Standard HDMI Cables are recommended for cable and satellite televisions, screen projectors, digital broadcast HD, upscaling DVD players, and other common displays.

Standard HDMI Cable with Ethernet

Standard HDMI Cable with Ethernet offers the same baseline capabilities and performance as that of Standard HDMI Cables. Additionally, it has a dedicated channel, known as the HDMI Ethernet Channel. Both linked devices should have HDMI Ethernet Channel enabled for data transmission functionality.

Note that this cable does not transmit 4K resolution. Likewise, very few products exist which can support Ethernet over HDMI compatibility. For example, Blu-Ray Disc Players and Home Theater Systems support Ethernet streaming channels.

Standard Automotive HDMI Cable

The Standard Automotive HDMI Cable is designed for internal cabling of vehicles equipped with onboard high-definition video and audio systems. It supports 720p up to 1080i resolution but does not support the HDMI Ethernet Channel.

An automotive system may be wired with one or more internal relays that can affect signal strength. To compensate with this, this cable needs to send a stronger signal than other cable types. Hence, Standard Automotive HDMI Cables are tested with much higher performance standards.

A resistant cable, this cable type can withstand the unique stresses (vibration and temperature extremes) present in motoring environments. Using this automotive connection system, car manufacturers now can have a viable solution for HD distribution within a vehicle.

High Speed HDMI Cable

High Speed HDMI Cables handle resolutions of 1080p up to 4K at 60 Hz. This type also includes display technologies such as 3D and Deep Color. High Speed HDMI Cables are recommended in a configuration where a 1080p display is being connected to a 1080p source, such as 4K-capable video game console or a Blu-Ray Disc Player.

High Speed HDMI Cable with Ethernet

High Speed HDMI Cables with Ethernet provide the same features of High Speed HDMI Cables including resolutions of 1080p to 4K. It also includes display technologies such as 3D and Deep Color. Similar to Standard HDMI Cables with Ethernet, it has a dedicated channel called the HDMI Ethernet Channel. Both linked devices should have HDMI Ethernet Channel enabled for data transmission functionality.

There are very few products that support Ethernet over HDMI compatibility existing. For example, Blu-Ray Disc Players and Home Theater Systems support Ethernet streaming channels.

High Speed HDMI Automotive HDMI Cable

This cable is for automotive use and is designed and tested to meet higher performance requirements for High Speed HDMI Cables. It is enabled to handle resolutions of 1080p and beyond, including advanced display technologies such as 4K, 3D and Deep Color.

Premium High Speed HDMI Cable and Premium High Speed HDMI Cable with Ethernet

These are special certification designations for High Speed HDMI Cables that have been designed for reliable performance when using 4K or Ultra HD (UHD) videos. These cables include features such as resolution at 60 frames per second with High-Dynamic Range (HDR), expanded color spaces including BT:2020 and 4:4:4 chroma sampling.

These cables offer low EMI (Electromagnetic Interference) that reduces interferences with nearby wireless devices. They are also identified by HDMI’s LIcensing Administrator’s Premium HDMI Cable Certification Label for authentication verification.

Ultra High Speed HDMI Cable

Ultra High Speed HDMI Cables can deliver high-bandwidth features including 4K, 5K (5120×2880), 8K (1780×4320), and 10K (10328×7760) at 120 Hz. This cable supports 48 Gbps bandwidth and features low EMI. It also includes the HDMI Ethernet Channel as a valuable feature.



HDMI cables are immensely remarkable devices and can help consumers have that ultimate audio/video experience they’ve always wanted. The relative confusion about the several types of HDMI cables is nothing compared to the quality and convenience they offer. Consumers just have to be keener when it comes to choosing the cables best-suited for their needs.

Koincable has several HDMI cables to choose from. Depending on the specifications and features required, Koincable guarantees that you can find exactly all the cables you need.
