HDMI
Definition
HDMI (High-Definition Multimedia Interface) 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.
Why It Matters
HDMI became the de facto standard for connecting consumer electronics, replacing a mess of older analog cables with a single digital cable for both high-definition video and audio.
Contextual Example
You use an HDMI cable to connect your gaming console, Blu-ray player, or computer to your TV.
Common Misunderstandings
- There have been multiple versions of HDMI (1.4, 2.0, 2.1), each adding support for higher resolutions, faster refresh rates, and new features.
- DisplayPort is a competing standard that is more common on computer monitors and often offers higher performance capabilities than HDMI.
