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
