Plug-and-Play
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 computer 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.
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 which are hard to see and do not affect the display
quality or usability. For more information on LCD Monitor Pixel Policy, see Dell support site
at: http://www.dell.com/support/monitors.
