Abstract
The present invention employs two unique identification files associated with the same dual-interface display monitor. Each identification file identifies one of the display monitor's two interfaces, so that each identification file identifies the display monitor as a separate display monitor, with a unique product code and its associated characteristics, to the computer system. When an initiating event occurs, such as a power on self test, hot plug-in, or reboot, the monitor responds to a request for its identification file with the digital identification file if the monitor is connected to the digital video connector and with the analog identification file if the monitor is connected to the analog video connector. If both connectors are connected, the monitor with send the digital identification file as a default. In the preferred embodiment, the identification files are EDID™ files.
