Plug-and-Play
You can install the display in any Plug-and-Play-compatible system. The display automatically
provides the computer system with its extended display identification data (EDID) using display
data channel (DDC) protocols so the computer can configure itself and optimize the display
settings. Most display installations are automatic; you can select different settings if desired. For
more information about changing the display settings, see
