Recommended Use
• For optimum performance, allow 20 minutes for warm-up.
• Rest your eyes periodically by focusing on an object at least
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!
• Adjust the monitor’s brightness, contrast and sharpness
controls to enhance readability.
• Avoid displaying fixed patterns on the monitor for long
periods of time to avoid image persistence (after image

following:
• Use the preset Size and Position controls with standard
signals.
• Use the preset Color Setting.
• Use non-interlaced signals.
• 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.
