What does 'EDID' stand for in AV technology?

EDID stands for Extended Display Identification Data. In AV technology, EDID is a metadata format that provides essential information about a display device to a video source. This information can include details such as the manufacturer’s name, product type, native resolutions, and supported audio formats. By utilizing EDID, devices can automatically configure themselves to ensure optimal video and audio output, thus simplifying the setup process in AV systems.

The significance of EDID lies in its ability to enable interoperability among different devices, allowing for seamless communication and ensuring that the connected video source sends the correct resolution and refresh rate to the display. This ability to communicate device capabilities enhances user experience in environments such as multimedia presentations and home theaters. Other options do not accurately define the term or relate closely to the functionality provided by EDID in AV systems.
