HDMI stands for High-Definition Multimedia Interface. It is the global industry standard for connecting high-resolution components — like a 4K Blu-ray player, PlayStation 4 or cable box — to HDTVs, 4K TVs or home theater A/V receivers that are HDMI capable. This is an all-digital interface that does not compress transferred data. As a result, HDMI produces superior picture and sound quality compared to other connections.
Because most audio and video components process information digitally, older analog cables require data conversion. Information can be lost that way. An HDMI connection keeps data in its original, uncompressed digital format, so you experience better picture and sound quality.
Other types of A/V connections require separate cables for audio and video data. But a single HDMI cord carries both data streams, which simplifies setup and reduces cord clutter.
HDMI accommodates existing high-definition video resolutions (720p, 1080p, 4K), plus it has capacity for future technologies. HDMI-connected components are also intelligent. They communicate to deliver the top video and audio formats that are mutually supported by your equipment.
HDMI is also favorable because of its backward compatibility with prior versions. This means you can use an older HDMI cable with a newer HDMI-equipped device, or vice versa, and still get terrific picture and sound. Additionally, HDMI is backward compatible with DVI (Digital Visual Interface) with the use of an adapter. However, DVI passes video data only.
Which HDMI Cable Do I Need?
Best Buy offers a large selection of HDMI cables. Begin by measuring the distance between devices to determine the necessary cable length. A long HDMI cable or an HDMI extender might be best for your arrangement.
Increase your setup options with cables that are certified for in-wall installation. For instance, if you want to mount Samsung TVs to the wall, buy in-wall HDMI cables so they can be hidden from sight.
Ultimately, you should look for an HDMI cable that supports the video resolution and features you wish to enjoy. Remember, your linked devices must share those capabilities for full performance. To support resolutions of 1080p and beyond, plus technologies like 3D and 4K Ultra HD, choose a high-speed HDMI cable. Some cables also include support for advanced features, like HDR and expanded color. An HDMI cable with Ethernet includes a dedicated channel for devices to share an Internet connection.
