HDMIkábel

An HDMI kábel, short for High-Definition Multimedia Interface cable, is a digital audio/video interface cable used to transmit uncompressed high-definition video and compressed or uncompressed digital audio. It is a common standard for connecting devices such as Blu-ray players, game consoles, computers, and televisions. HDMI technology was developed by a consortium of electronics manufacturers.

The primary function of an HDMI kábel is to provide a single cable solution for both audio and video signals, eliminating the need for multiple cables that were common with older analog technologies. This simplifies connections and can improve signal quality by reducing interference. HDMI supports various video resolutions, including standard definition, high definition (720p, 1080i, 1080p), and ultra-high definition (4K, 8K). It also supports multiple audio formats.

There have been several versions of the HDMI standard, each introducing improvements and new features. These include increased bandwidth for higher resolutions and frame rates, support for 3D video, and enhanced audio capabilities like Dolby Atmos. The physical connector for HDMI is standardized, though variations exist for smaller devices like smartphones and tablets (e.g., Mini HDMI and Micro HDMI). When choosing an HDMI kábel, it's important to ensure it supports the features required by the connected devices, such as the desired resolution, refresh rate, and any specific HDMI version features like HDR (High Dynamic Range).
