In this article, we focus on HDMI cables specifically. HDMI cables have different versions, which have evolved alongside the electronics versions to enable the latest HDMI technology to work effectively. However, instead of numbers they have names. We know. Why not just use the numbers?! So allow us to walk you through it. In this article we’ll learn what these cable names mean, from the basic Standard HDMI Cable to the Advanced Ultra High-Speed HDMI Cable, and how you can make more informed choices and select the right HDMI cables for your devices in your next project.
An introduction to HDMI Cable Versions
HDMI cables are essential conduits that have evolved over time to keep pace with the ever-advancing world of audio-visual technology. It’s worth noting upfront that every HDMI cable is designed:
- for backwards compatibility with previous versions, and
- to effectively support every HDMI feature.
Before we delve into the details, here’ a quick summary of the evolution of HDMI cable versions, highlighting their key developments:
2003: Standard HDMI Cable – Up to 1080p and 720p
The ‘Standard HDMI Cable’ made its debut alongside the HDMI 1.0 specification, ushering in a new era of audio and visual connectivity. Initially this only supported up to around 4.95Gbps. This cable was designed for basic audio and video needs and supported resolutions up to 1080p and 720p.

2009: Standard HDMI Cable with Ethernet
As our technological needs grew, HDMI introduced the ‘Standard HDMI Cable with Ethernet’. This cable not only supported the same resolutions as the Standard HDMI Cable but also came equipped with Ethernet capabilities, simplifying setups and reducing cable clutter.
2009: High-Speed HDMI Cable with Ethernet
Building upon the capabilities of its predecessor, HDMI then introduced the ‘High-Speed HDMI Cable with Ethernet’ in the same HDMI 1.4 specification. This cable combined high-resolution support with networking capabilities, making it a valuable addition to modern home theatres and multimedia setups.
2009: Standard Automotive HDMI Cable
HDMI took to the open road with the ‘Standard Automotive HDMI Cable’. This was specially designed for in-car entertainment systems. Honda was one of the first adopters of this cable type, installing it into the Honda Odyssey.
2015: Premium HDMI Cable
The HDMI Premium Cable was the first optional certification, a departure from the previously mandatory certifications required to use the HDMI mark. These cables support a wide range of resolutions, including 4K and advanced features like 4K60, HDR and expanded colour spaces.
2017: Ultra High-Speed HDMI Cable
The current pinnacle of HDMI cable technology was reached in 2017 with the ‘Ultra High-Speed Cable’. Engineered to handle the most demanding tasks of today’s technology, this cable boasts support for 8K resolutions, high frame rates, dynamic HDR and more, making it ideal for future-ready setups that embrace the latest advancements in audio and visual quality.
All these cable versions are still on the market and can still be used to this day for appropriate devices, so let’s now delve into the cable versions in more detail.
Standard HDMI Cable: Up to 1080p and 720p
As always, it makes sense to start this story at the beginning. So our exploration of HDMI cable versions begins with the ‘Standard HDMI Cable’, the foundation for HDMI technology. This cable is designed for simplicity and reliability, making it a popular choice for various applications.
The Standard HDMI Cable is tailored to meet basic audio and video needs, offering a versatile and straightforward solution. It supports resolutions up to 1080p and 720p (for a quick refresher on data rates, click here), ensuring clear and satisfactory audio-visual experiences. While it may not venture into the realms of ultra high-definition, it remains an efficient choice for many scenarios.
This cable version is particularly suitable for older devices and setups where high-definition content isn’t a primary concern. If you have an older TV or a straightforward audio arrangement, the Standard HDMI Cable can effectively serve your needs.
One of its standout features is affordability, as this cable has been around for over two decades. Standard HDMI Cables are often the most budget-friendly option in the HDMI cable spectrum. This accessibility ensures that basic AV connections are within reach for a wide range of basic HDMI applications where higher resolutions and performance aren’t required such as CCTV monitors etc.
High-Speed HDMI Cable: 1080p, 4K 30 Hz, 3D, and Deep Colour
The ‘High-Speed HDMI Cable’ is a versatile and dependable choice designed to meet the demands of higher resolutions and advanced features. This cable is engineered to excel in multiple aspects of audio-visual transmission, enhancing overall viewing and entertainment experiences.
With its introduction more connector types were offered, including the Type C mini and type D micro. These connector types proved very popular with compact HDMI-enabled devices, such as digital camera and camcorders, allowing them to be plugged directly into display devices.
One of the key strengths of the High-Speed HDMI Cable is its capability to support resolutions up to 1080p. This makes it particularly suitable for Full HD displays, and at the time of its launch, allowed viewers to experience content with remarkable new clarity and detail.
In addition to Full HD support, this cable offers compatibility with 4K content at 30 Hz. This means that users can take advantage of the increasing availability of 4K content, which provides even higher resolution and more detailed images. While it may not match the 60 Hz capability of higher-speed cables, the High-Speed HDMI Cable still works for those who have 4K displays and are reluctant to upgrade their cable due to physical limitations, such as it being permanently installed in a wall!
Furthermore, this cable is specifically designed to support 3D content. On the whole, 3D content has been a passing fad that had a life span of only a couple of years or so. The demand for 3D content has been eclipsed by the promise of 8K resolution.
One notable feature is its support for deep colour. Deep colour technology expands the spectrum of hues that can be displayed, resulting in more vibrant and lifelike images. This enhancement is especially valuable when viewing content that relies on a wide range of colours, as the technology allows compatible displays to resolve the significant difference between the darkest blacks and the brightest whites, resulting in more defined and visually striking images. Deep colour ensures that you see content as intended by its creators, with rich and true-to-life colours and high contrast ratio colours.
Standard HDMI Cable and High-Speed HDMI Cable with Ethernet
The ‘with Ethernet’ cable version takes the capabilities of the standard and high speed versions and expands them to include integrated networking features. In practice, the need for both audio-visual and internet connections in a single cable is relatively rare. However, it potentially simplifies cable management significantly by combining audio, video and networking functions into one streamlined solution. The original design was well-intended but generally not adopted by device manufacturers, so it never gained traction in the market.
In modern multimedia setups, both the Standard HDMI Cable with Ethernet and High-Speed HDMI Cable with Ethernet offer the possibility of supporting the latest eARC (enhanced Audio Return Channel) features using the additional twisted pair that was destined for the ethernet functionality.
