All display devices (monitors, projectors, and televisions), analog or digital, must supply Extended Display Identification Data (EDID), which is stored in the monitor's EEPROM. Sometimes during manufacturing, incorrect or incomplete EDID might be flashed on the EPROM. Such EDIDs can lead to problems such as setting incorrect display modes.
This paper describes how monitor manufacturers can avoid reflashing the monitor's EEPROM by implementing a monitor INF that overrides part of, or the entire, EDID information in software. This white paper describes how to implement such an INF.
This information applies for the following operating systems:
