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.
