About your display | 25
Plug-and-Play
You can install the display in any Plug-and-Play-compatible system. The display
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 display settings. Most display installations are automatic; you
can select different settings if desired. For more information about changing the
display settings, see Operating the Display.
LCD display quality and pixel policy
During the LCD display 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 Display Pixel Policy, see
Dell support site at: https: //www.dell.com/pixelguidelines.
Maintenance guidelines
Cleaning your display
WARNING: Before cleaning the display, unplug the display power cable
from the electrical outlet.
CAUTION: Read and follow the Safety Instructions before cleaning the
display.
For best practices, follow these instructions in the list below while unpacking, cleaning,
or handling your display:
• To clean your anti-static screen, lightly dampen a soft, clean cloth with water. If
possible, use a special screen-cleaning tissue or solution suitable for the anti-static
coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or compressed
air.
• Use a lightly-dampened, soft cloth to clean the display. Avoid using detergent of
any kind as some detergents leave a milky film on the display.
• If you notice white powder when you unpack your display, wipe it off with a cloth.
• Handle your display with care as a darker-colored display may get scratched and
show white scuff marks more than a lighter- colored display.
• To help maintain the best image quality on your display, use a dynamically changing
screen saver and turn off your display when not in use.
