EDID (Extended Display Identification Data)

EDID (Extended Display Identification Data) is a small amount of information stored in a monitor or display device that communicates its capabilities to a computer or graphics source. It includes details like resolution, refresh rate, color support, and audio capabilities. This data allows the computer to automatically adjust its output settings for optimal display quality without manual configuration. Essentially, EDID helps devices "understand" each other to ensure compatible and best-performing visual and audio output.
