26 | About your monitor
Plug and Play capability
You can connect the monitor to 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 as required. 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 Dell Monitor Quality and Pixel
Policy, see
