High-Definition Multimedia Interface

Sign in to edit

High-Definition Multimedia Interface (HDMI) is an industry standard for connecting digital audio and video devices through a single cable. HDMI can connect any audio/video source, such as a set-top box, DVD player, or A/V receiver to an audio and/or video output device such as a digital television (DTV).

Description[]

HDMI supports standard, enhanced, and high-definition video, plus multi-channel digital audio. It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS), HDMI 1.3 adds additional support for new lossless digital audio formats Dolby TrueHD and DTS-HD Master Audio with bandwidth to spare to accommodate future enhancements. HDMI 1.4 incorporates connection via Ethernet.

HDMI was created by Hitachi, Panasonic, Philips, Sony, Thomson (RCA), Toshiba, and Silicon Image. It also has the support of major motion picture producers and distributors.[1]

Support by Apple devices[]

The only portable Mac models to directly include an HDMI port were the 15 and 13-inch MacBook Pros with Retina display, introduced in 2012 and 2013, respectively. All other models since then require a USB-C Digital AV Multiport Adapter or a 3rd-party Mini DisplayPort to HDMI adapter or cable.[2] Among desktop models, the Mac Mini has included HDMI support since the thinner aluminum form factor was introduced with its 3rd generation update in 2010.[3] Direct support by Mac Pro models depends on the installed graphics card or adapter.

iOS and iPadOS devices with Lightning ports require a Lightning Digital AV Adapter to support HDMI. Older devices with 30-pin dock connectors would need a Apple 30-pin to Digital AV Adapter.[4]
