For best practices, follow the instructions in the list below while unpacking,
cleaning, or handling your monitor:
• To clean your antistatic screen, lightly dampen a soft, clean cloth with

for the antistatic coating. Do not use benzene, thinner, ammonia,
abrasive cleaners, or compressed air.
• Use a lightly-dampened, warm cloth to clean the monitor. Avoid using
