High-Definition Multimedia Interface ( HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. [3] HDMI is a digital replacement for analog video standards. If you’ve got a long connection to set up – running from one floor of the house to another, perhaps – then you’ll want to invest in an extra-long HDMI cable. KabelDirect’s 20m HDMI cable is an excellent example and offers a 2.0 connection. Best of all, it comes with a 36-month warranty. A new certification program was introduced in October 2015 to certify that cables work at the 18Gbit/s maximum bandwidth of the HDMI 2.0 specification. [79] In addition to expanding the set of cable testing requirements, the certification program introduces an EMI test to ensure cables minimize interference with wireless signals. These cables are marked with an anti-counterfeiting authentication label and are defined as: [80] HDMI has become the standard connection for hooking up your TV or projector to Blu-ray players, media streamers, set-top-boxes, gaming consoles and home cinema systems. And while it’s now been around for nearly 20 years, it keeps evolving to cover new resolutions and features.

Standard HDMI cables have a maximum resolution of 1080p. They also support 3D video and Audio Return channels. It is typically used to connect televisions to DVD players, gaming consoles, and other devices. Standard HDMI cables are available in lengths up to 25 feet. Uncompressed 8 bpc (24 bit/px) color depth and RGB or Y′C BC R 4:4:4 color format are assumed on this table except where noted. An HDMI repeater extends the connection for shorter runs by connecting two HDMI cables and amplifies the signals for better transmission.To determine if an HDMI cable version supports a particular refresh rate, measured in Hertz (Hz), you will have first know the resolution you want to use for your display. Higher resolutions take up more data, and each HDMI version has different limits.

As of January2021 [update], nearly 10 billion HDMI devices had been sold.
