HDMI stands for High-Definition Multimedia Interface. It is a global industry standard for connecting high-resolution components — like a 4K Blu-ray player, cable box or PlayStation 5— to HDTVs, 4K TVs or home theater systems. HDMI-connected components communicate with each other to deliver video and audio formats that are mutually supported by your equipment. This allows HDMI cords to help you create optimized gaming set-ups and great home theaters with pristine picture and audio quality.
Unlike classic A/V cables, which use analog signals, an HD cable connection keeps data in an uncompressed digital format. So, if you are working with digital content on both ends of your connection, you will experience top-notch picture and sound quality when using an HDMI cable. Plus, other types of A/V connections require separate cables for audio and video data, but a single HDMI cord carries both data streams at once, reducing cord clutter.
Not only does HDMI accommodate existing high-definition video resolutions (720p, 1080p, 4K, 8K), but it has the capacity to support future technologies as well. This is why investing in higher end HDMI cables now that support 8K will pay off once the technology catches up.
