• If you notice white powder when you unpack your monitor, wipe it off with a
cloth.
• Handle your monitor with care as a dark-colored monitor may get scratched
and show white scuff marks more than a light-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.
