Such an override is frequently made available to customers through Windows Update or digital media in the shipping box, and receives higher precedence than the EDID override mentioned here. ![]() In addition to replacing the EDID information, a vendor can provide an override for the monitor name and the preferred display resolution. Windows extracts the updated EDID information from the INF and provides it to components instead of using the EEPROM EDID information, effectively overriding the EEPROM EDID. The better solution, described here, is for the manufacturer to implement an INF file that contains the correct EDID info, and have the customer download it to the computer that is connected to the monitor.Have the customer send the monitor back to the manufacturer, who reflashes the EEPROM with the correct EDID and returns the monitor to the customer.There are two approaches to correcting EDIDs: Incorrect or invalid EDID information on the monitor’s EEPROM can therefore lead to problems such as setting incorrect display modes. For example, during initialization the monitor driver queries the Windows Display Driver Model (WDDM) driver for its brightness query interface and device driver interface (DDI) support, which is in the EDID. ![]() Monitors provide the EDID to Microsoft Windows components, display drivers, and some user-mode applications. This data is stored in the monitor’s EEPROM in a format that is specified by VESA. Approaches to correcting EDIDsĪll monitors, analog or digital, must support EDID, which contains information such as the monitor identifier, manufacturer data, hardware identifier, timing info, and so on. This topic describes how vendors and manufacturers can override the Extended Display Identification Data (EDID) of any monitor through an INF file, and provides a sample INF file ( Monsamp.inf).įor information on how to use and modify Monsamp.inf, see Monitor INF File Sections. ![]()
