Plug and Play Capability
You can install the monitor in any Plug and Play-compatible system. The monitor automatically provides the computer system with its Extended Display
Identification Data (EDID) using Display Data Channel (DDC) protocols so the system can configure itself and optimize the monitor settings. Most monitor
installations are automatic; you can select different settings if desired. For more information about changing the monitor settings, see Operating the monitor.
