Plug-and-Play

You can install the monitor in any Plug-and-Play-compatible computer. The
monitor automatically provides its Extended Display Identification Data (EDID) to the
computer 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 dierent settings if desired. For more information about changing the
monitor settings,see Operating the Monitor.

LCD Monitor Quality and Pixel Policy

During the LCD Monitor manufacturing process, it is not uncommon for one or
more pixels to become fixed in an unchanging state. These are hard to see and
do not aect the display quality or usability. For more information on Dell Monitor
Quality and Pixel Policy, see dell.com/support/monitors.
