y Rest your eyes periodically by focusing on an object at least 5 feet away. Blink often.
y Position the monitor at a 90° angle to windows and other light sources to minimize glare and reflections.
y Clean the LCD monitor surface with a lint-free, nonabrasive cloth. Avoid using any cleaning solution or glass cleaner!
y Adjust the monitor’s brightness, contrast and sharpness controls to enhance readability.
y Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after image effects).

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