The latest in a series of Kordz’ articles outlining the essentials of HDMI technology explores key features, as well as hidden and seldom-used functionality, to optimise audio-visual performance.  

June 4, 2024 – HDMI technology has improved the performance of audio and video systems immensely and it’s the understanding of HDMI features that is the key to systems integrators optimising their audio-visual setups. Unlike HDMI cables, which physically transmit signals, HDMI features define how these signals are interpreted and utilised by devices. So, whether configuring a home theatre, gaming console, or professional AV setup, familiarity with HDMI features empowers integrators to make smarter decisions, ensuring seamless compatibility and optimal performance in their projects.

Despite the industry’s general knowledge of HDMI features, there remains some confusion and little-known aspects of HDMI that are valuable for integrators to keep in mind, which is why Kordz has put together an informative article that explores commonly overlooked nuances and intricacies. The third in Kordz’ popular HDMI Demystified series, HDMI Demystified: Exploring the Features, delves deep into the technologies behind each specific feature, helping systems integrators choose the best cabling for the job while preparing their AV systems for the future.  

Kordz begins by explaining the performance advantages of audio features found in some HDMI cables including Audio Return Channel (ARC) and Enhanced Audio Return Channel (eARC). By understanding the differences and benefits of each attribute to audio reproduction, systems integrators can deliver rich and immersive audio experiences. 

The unique features of an HDMI cable also impact video performance, so Kordz breaks down the finer points here, as well, including the cable’s support of Source-Based Tone mapping, Deep Colour, High Dynamic Range (HDR), and Extended Display Identification Data (EDID), outlining the impact of these technologies on the viewing experience. 

In addition to these core functionalities are a litany of other features that can play a critical role in the performance of an AV system, which Kordz thoroughly explains, including HDMI with Ethernet, Consumer Electronics Control (CEC), Variable Rate Refresh (VRR), and High-Bandwidth Digital Content Protection (HDCP).  

“Whether a customer needs basic connections or seeks high-definition perfection, there’s a specific HDMI solution for every project and application,” says James Chen, Kordz managing director. “The trick is selecting the correct HDMI cable for the job and budget, and this third chapter of our HDMI Demystified series provides systems integrators with a shopping list of sorts when selecting an HDMI cable that will ensure optimal performance and interoperability now and in the future.”
