HDMI Cable Overview

This latest HDMI Cable is the only cable that complies with stringent specifications designed to ensure support for all HDMI 2.1b 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.

Premium HDMI Cables are a special certification for High Speed HDMI Cables that have been designed and certified for ultra-reliable performance for 4K/UltraHD at up to 18Gbps bandwidth including advanced features such as 4K60, HDR, and expanded color spaces including BT.2020. They have low EMI and are identified by HDMI LA’s Premium HDMI Cable Certification Label for authentication and in-field verification.

This cable type offers the same baseline performance as the High Speed HDMI Cable with an additional dedicated data channel, known as the HDMI Ethernet Channel, for device networking. HDMI Ethernet Channel functionality is only available if both linked devices are HDMI Ethernet Channel-enabled.

The High Speed HDMI Cable is designed and tested to handle video resolutions of 1080p and beyond with support up to 10.2Gbps bandwidth, including advanced display technologies such as 4K@30Hz, 3D, and Deep Color. If you are using any of these technologies, or if you are connecting your 1080p HD display to a 1080p HD content source, such as a Blu-ray Disc player, this is the recommended cable.

Since an automotive system may be wired with one or more internal relays that can affect signal strength, the High Speed Automotive HDMI Cable needs to send a stronger signal than other cables types, so it is tested to higher performance standards. It also may utilize a special dust and vibration-resistant HDMI Type E connector with locking tab.

This cable type offers the same baseline performance as the Standard HDMI Cable, plus an additional, dedicated data channel, known as the HDMI Ethernet Channel, for device networking. HDMI Ethernet Channel functionality is only available if both linked devices are HDMI Ethernet Channel-enabled.

The Standard HDMI cable is designed to handle some earlier consumer applications, and is tested to reliably transmit 1080i or 720p video. Most of these cables have been replaced by the High Speed HDMI Cables but there are still some in the marketplace and consumers should note while fine for some uses, they don’t support the later resolutions, refresh rates and bandwidth requirements.
