• Avoid displaying fixed patterns on the monitor for long periods of time to
avoid image persistence (after-image effects).
• Get regular eye checkups.
Ergonomics
To realize the maximum ergonomics benefits, we recommend the following:
• Adjust the Brightness until the background raster disappears
• Do not position the Contrast control to its maximum setting
• Use the preset Size and Position controls with standard signals
• Use the preset Color Setting
• Use non-interlaced signals with a vertical refresh rate between
60-75 Hz
• Do not use primary color blue on a dark background, as it is difficult to
see and may produce eye fatigue to insufficient contrast
