Plug-And-Play; Lcd Monitor Quality And Pixel Policy - Dell S2421HSX User Manual

Plug-and-play

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 that 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 about LCD Monitor Pixel Policy,
see Dell support site at: https://www.dell.com/pixelguidelines.
