Variations of HDMI Cables

While HDMI is the standard, there are different versions and types of HDMI cables, each supporting varying levels of features and bandwidth. It’s important to choose the correct HDMI cable based on your equipment’s specifications. Here are the common types:

• Standard HDMI: Suitable for 720p and 1080i resolutions. Generally, this is an older standard and not suitable for current high-resolution requirements.
• High-Speed HDMI: Supports 1080p, 4K at 30Hz, and 3D. A step up from standard, but not always the best option for more advanced setups.
• Premium High-Speed HDMI: This cable is certified for 4K at 60Hz with HDR (High Dynamic Range) and is the standard for most new high-resolution devices and setups.
• Ultra High-Speed HDMI: Supports 8K at 60Hz or 4K at 120Hz, and eARC (enhanced Audio Return Channel). Essential for the latest gaming consoles and high-end displays.

How to Choose the Correct HDMI Cable for Your Installation

Here are a few steps to guide you to the correct HDMI cable for your installation.

1. Identify Your Equipment’s Specifications: Check the capabilities of all devices that will be connected (TV, monitors, consoles, cameras, etc.) for their output and input resolutions and frame rates.
2. Match the Cable to the Highest Requirements: Choose the HDMI cable that matches or exceeds the highest resolution, refresh rate, and features required by any of your devices. For example, if one device is 4K/120hz make sure to choose at least a high-speed HDMI cable.
3. Consider Cable Length: HDMI signal quality can degrade over longer distances. If you need a longer cable, ensure it’s high-quality and consider active HDMI cables or using an HDMI extender for very long runs.
4. Check Cable Certification: Look for certification labels that guarantee the cable meets the HDMI specifications. Premium High-Speed and Ultra High-Speed HDMI cables have certification programs ensuring their performance.
5. Think about Future Upgrades: Always plan a bit ahead. If you plan to upgrade to a higher resolution or refresh rate device in the future, choose a cable that will support those parameters from the outset to avoid having to replace it.
