Plug and play capability

You can install the monitor in any Plug and Play-compatible system. The monitor automatically

provides the computer 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 your

monitor.

LCD monitor quality and pixel policy

During the LCD Monitor manufacturing process, it is normal 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 about Dell Monitor Quality and Pixel Policy, see Dell Support

site at https://www.dell.com/support/monitors.
