Maintenance guidelines

Cleaning your monitor

WARNING: Before cleaning the monitor, unplug the monitor power cable
from the electrical outlet.
CAUTION: Read and follow the
monitor.
Improper cleaning methods can result in physical damage to Dell monitors. Physical
defects may affect the screen and body of the monitor.
Follow the instructions in the list below when cleaning the monitor:
• To clean the Dell monitor screen, lightly dampen a soft, clean cloth with water.
If possible, use a special screen-cleaning tissue or solution suitable for the Dell
monitor screen.
CAUTION: Do not use detergents of any kind or other chemicals such as
benzene, thinner, ammonia, abrasive cleaners, alcohol, or compressed air.
WARNING: Do not directly spray the cleaning solution or even water
directly on the surface of the monitor. Doing so will allow liquids to
accumulate at the bottom of the display panel and corrode the electronics
resulting in permanent damage. Instead, apply the cleaning solution or
water to a soft cloth and then clean the monitor.
CAUTION: Using chemicals for cleaning may cause changes in the
appearance of the monitor, such as color fading, milky film on the monitor,
deformation, uneven dark shade, and screen surface peeling.
NOTE: Monitor damages due to improper cleaning methods and the use
of benzene, thinner, ammonia, abrasive cleaners, alcohol, compressed air,
detergent of any kind will lead to a Customer Induced Damage (CID). CID is
not covered under the standard Dell warranty.
• If you notice white powder when you unpack your monitor, wipe it off with a
cloth.
• Handle your monitor with care as a darker-colored monitor may get scratched
and show white scuff marks more than a lighter-colored monitor.
• To help maintain the best image quality on your monitor, use a dynamically
changing screen saver and turn off your monitor when not in use.
