Maintenance guidelines
Cleaning your monitor
WARNING: Before cleaning the monitor, unplug the monitor power
cable from the electrical outlet.
CAUTION: Read and follow the Safety instructions before cleaning the
monitor.
For best practices, follow the instructions in the list below while unpacking, cleaning
or handling your monitor:
• To clean your 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 cloth to clean the monitor. Avoid using detergent of
any kind as some detergents leave a milky film on the monitor.
• If you notice white powder when you unpack your monitor, wipe it off with a
cloth.
• Handle your monitor with care as the black-colored monitor may get
scratched and show white scuff marks.
• 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.
