5 feet away. Blink often.
• Position the monitor at a 90° angle to windows and other
light sources to minimize glare and reflections.
• Clean the LCD monitor surface with a lint-free, non-abrasive
cloth. Avoid using any cleaning solution or glass cleaner!

controls to enhance readability.
• Avoid displaying fixed patterns on the monitor for long
periods of time to avoid image persistence (after image

Ergonomics
To realize the maximum ergonomic benefits, we recommend
the following:
• Use the preset Size and Position controls with standard
signals.
• Use the preset Colour Setting.
• Use non-interlaced signals.
• Do not use primary colour blue on a dark background, as it
is difficult to see and may produce eye fatigue due to
insufficient contrast.

• When the liquid crystal panel is stained with dust or dirt,
please wipe with soft cloth gently.
• Please do not rub the LCD panel with hard material.
• Please do not apply pressure to the LCD surface.
