[. . . ] Your eyes should look slightly downward when viewing the middle of the screen. · Position your monitor no closer than 16 inches and no further away than 28 inches from your eyes. · Rest your eyes periodically by focusing on an object at least 20 feet away. · Position the monitor at a 90° angle to windows and other light sources to minimize glare and reflections. Adjust the monitor tilt so that ceiling lights do not reflect on your screen. · If reflected light makes it hard for you to see your screen, use an anti-glare filter. · Clean the LCD monitor surface with a lint-free, non-abrasive cloth. · Adjust the monitor's brightness and contrast controls to enhance readability. · 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. · Avoid displaying fixed patterns on the monitor for long periods of time to avoid image persistence (after-image effects). 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 60-75Hz · Do not use primary color blue on a dark background, as it is difficult to see and may produce eye fatigue to insufficient contrast For more detailed information on setting up a healthy work environment, call NEC at (800) 820-1230, NEC FastFactsTM information at (630) 467-4363 and request document #900108 or write the American National Standard for Human Factors Engineering of Visual Display Terminal Workstations ­ ANSI-HFS Standard No. Box 1369, Santa Monica, California 90406. 13 1525X. wpc 15 11/5/99, 12:56 PM Specifications Monitor Specifications LCD Module Diagonal: Viewable Image Size: Native Resolution (Pixel Count): Video: Sync: MultiSync® LCD1525XTM Monitor 15. 0 inch 15. 0 inch 1024 x 768 ANALOG 0. 7 Vp-p/75 Ohms Separate sync.

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. NOTE: Technical specifications are subject to change without notice. 14 1525X. wpc 16 11/5/99, 12:56 PM Features ambixTM Technology: Dual input technology allowing both analog and digital inputs off of one connector (DVI-I) as well as additional legacy analog support off of a traditional 15-pin VGA connector. Provides traditional MultiSync® technology compatibility for analog as well as TMDSTM-based (Transition Minimized Differential Signaling) digital compatibility for digital inputs. DVI-I: The intergrated interface ratified by the Digital Display Working Group (DDWG) that allows both digital and analog connectors off of one port. The "I" stands for integration for both digital and analog, The digital portion is TMDSbased. [. . . ] TCO'99 requirement permits the inclusion of lead since no replacement has yet been developed. Cadmium** Cadmium is present in rechargeable batteries and in the colourgenerating layers of certain computer displays. TCO'99 requirement states that batteries, the colourgenerating layers of display screens and the electrical or electronics components must not contain any cadmium. Mercury** Mercury is sometimes found in batteries, relays and switches, Mercury damages the nervous system and is toxic in high doses. TCO'99 requirement states that batteries may not contain any Mercury. It also demands that no mercury is present in any of the electrical or electronics components associated with the display unit. CFCs (freons) CFCs (freons) are sometimes used for washing printed circuit boards. [. . . ]
