•Position whatever you are looking at most of the time (the screen or reference material) directly in front of you to minimize turning your head while you are typing.

•Get regular eye checkups.

Ergonomics

To realize the maximum ergonomics benefits, we recommend the following:

•Use the preset Size and Position controls with standard signals.

•Use the preset Colour Setting.

•Use non-interlaced signals with a vertical refresh rate between 60-75 Hz.

•Do not use primary colour blue on a dark background, as it is difficult to see and may produce eye fatigue to insufficient contrast.

*1 Interpolated Resolutions: When resolutions are shown that are lower than the pixel count of the LCD module, text may appear different. This is normal and necessary for all current flat panel technologies when displaying non-native resolutions full screen. In flat panel technologies, each dot on the screen is actually one pixel, so to expand resolutions to full screen, an interpolation of the resolution must be done.

*2 NEC-Mitsubishi Electronics Display cites recommended resolutions at 60 Hz for optimal display performance.

*3 If your display is not showing a picture for the SOG and Composite Sync. Signal, please contact our hotline for further assistance.
