The course of HDMI cable development

HDMI cable introduction

HDMI (High-Definition Multimedia Interface) is a cable used to transmit audio and video signals between devices such as a Blu-ray player, gaming console, television, or computer monitor. HDMI cables provide an uncompressed, all-digital audio/video interface, which means they can support enhanced picture and sound quality. This type of cable has become the industry standard for connecting high-definition audio/video components.

HDMI cable history
The development of HDMI cables began in 2002 with the release of HDMI 1.0. Since then, the technology has been continually developed and improved, with the latest version being HDMI 2.1. This version was released in 2017 and is capable of supporting high-speed data transfer and resolutions up to 8K ultra-high-definition (UHD).
