• Do not apply pressure to the screen or touch the screen with bare fingers or
objects. Pressure can affect image quality. Cosmetics and oils on the skin are
both detrimental to the screen and difficult to remove.
• Allow the display to warm up to room temperature before turning it on. Avoid
sudden temperature changes in the environment, as this may cause
condensation, which damages the display.
• Do not set up the display near strong light or heat sources.
• Do not block the vents on the back of the display or install the display in a
built-in enclosure. Blocked vents cause excessive heat to build up inside the
display, increasing risk of fire.
• When installing components, turn off your computer, but leave it plugged into a
grounded outlet.
• Do not remove the back cover or disassemble the display. There are no
user-serviceable parts inside.
Preventing fire and injury
• Replace the power supply cables if damaged.
• Use only the power source indicated in this guide or listed on the display.
• Do not plug the power supply into an overloaded AC outlet or extension cord.
Overloaded AC outlets and cords can result in electric shock or fire.
• Do not drop or push objects into the display case. Internal components contain
high voltage.
• Unplug the power cord from the wall outlet during thunderstorms.
• Do not place magnetic devices, such as motors, near the display.
