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 Dell Monitor
Quality and Pixel Policy, see www.dell.com/pixelguidelines.

Maintenance guidelines

Cleaning your monitor

WARNING: Using improper methods when cleaning the monitor can
result in a physical damage to the screen or the body of your Dell
monitor.
CAUTION: Read and follow the
monitor.
WARNING: Before cleaning the monitor, unplug the monitor power
cable from the electrical outlet.
For best practices, follow the instructions in the list below when unpacking,
cleaning, or handling your 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 or other chemicals such as benzene,
thinner, ammonia, abrasive cleaners, or compressed air.
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 peeling of screen area.
WARNING: Do not 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.
NOTE: Monitor damage 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.
