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.
