HDMI20

HDMI20 is a specification for High-Definition Multimedia Interface (HDMI) technology, officially known as HDMI version 2.0. Introduced in 2013, HDMI 2.0 significantly enhances the bandwidth and capabilities of previous HDMI standards, enabling higher-resolution video and improved audio features.

One of the key features of HDMI 2.0 is its increased bandwidth of up to 18 Gbps, which supports 4K video resolution at 60 frames per second (fps). This allows for smoother motion and higher image quality suitable for modern high-definition displays. HDMI 2.0 also expands color depth options, supporting 4:4:4 chroma subsampling at higher resolutions and refresh rates. It introduces support for Dual Video Streams, enabling multiple displays to be connected and used simultaneously through a single connector.

Audio enhancements are notable in HDMI 2.0 as well, with support for up to 32 audio channels and increased bandwidth for high-fidelity sound formats such as Dolby Atmos and DTS:X. These features make HDMI 2.0 suitable for advanced home theater and professional audio applications.

HDMI 2.0 is backwards compatible with earlier versions, ensuring seamless integration with existing HDMI devices. It utilizes HDMI Type A connectors but can also be found in other connector types such as Type C (Mini HDMI) and Type D (Micro HDMI).

Overall, HDMI 2.0 represents a significant step forward in multimedia interface technology, providing higher resolution, better color, richer audio, and multi-stream capabilities for modern video and audio systems.
