EDID (Extended Display Identification Data) is a set of information stored in a display’s EEPROM that allows its parameters to be automatically recognized by the source device (e.g. a computer or graphics card). EDID includes details such as the native resolution, maximum refresh rate, preferred modes, connector type (HDMI, VGA, DVI), color depth, manufacturer ID and serial number. This information is read via the DDC (Display Data Channel) bus, enabling automatic adjustment of image settings without user intervention.
Proper EDID support prevents issues like incorrect resolution, image distortion or no signal, and in industrial display systems it is crucial for compatibility and reliable operation.
