EDID (Extended Display Identification Data) is the protocol that allows sources (such as computers or media players) and displays (such as monitors or projectors) to communicate in order to ensure the display is sent the correct signal. EDID provides a way for the display to convey its capabilities (such as resolution, refresh rate, and color depth) to the source device, enabling the source to adjust its output to match these capabilities, thereby ensuring optimal display performance.
