The adoption of the new VESA Plug and Play solution eliminates complicated and
time consuming setup. It allows you to install your monitor in a Plug and Play compati-
ble system without the usual hassles and confusion. Your PC system can easily identi-
fy and configure itself for use with your display. This monitor automatically tells the PC
system its Extended Display Identification Data (EDID) using Display Data Channel
(DDC) protocols so the PC system can automatically configure itself to use the flat
panel display.
