EDID data exchange is a standardized means for a display to communicate its capabilities to a source device. The premise of this communications is for the display to relay its operational characteristics, such as its native resolution, to the attached source, and then allow the source to generate the necessary video characteristics to match the needs of the display. This maximizes the functional compatibility between devices without requiring a user to configure them manually, thus reducing the potential for incorrect settings and adjustments that could compromise the quality of the displayed images and overall reliability of the system.

楼主参考一下
Extended Display Identification Data (EDID) is a metadata format for display devices to describe their capabilities to a video source (e.g. graphics card or set-top box). The data format is defined by a standard published by the Video Electronics Standards Association (VESA).

延伸顯示能力識別(Extended display identification data,簡稱EDID)是指螢幕解析度的資料,包括廠商名稱與序號。一般EDID存在於顯示器的PROM或EEPROM內。一般如要讀取EDID都是透過I2C,slave address是0x50。目前HDMI 1.0 - 1.3c使用EDID結構1.3版。
