Dell UltraSharp U2424H User Manual page 42

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.
• If you notice white residual 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.
