Read and follow these instructions when connecting and using your computer monitor: q Disconnect the monitor from the power supply if the monitor is not to be used for an extended period of time. q q q q q Do not attempt to remove the back cover, as you will be exposed to a shock hazard. The back cover should only be removed by qualified service personnel. Do not place objects on top of the monitor cabinet, objects could fall into vents or cover them and prevent proper cooling of the monitor's electronic devices. To avoid the risk of shock or permanent damage to the set, do not expose the monitor to rain or excessive moisture.

HTM (8 of 18) [8/29/2001 2:55:48 PM] Glossary M Moiré effect A fringe pattern arising from the interference between two superimposed line patterns. In a monitor it comes from the interference between the shadow mask pattern and the video information (video moiré), and between the shadow mask pattern and the horizontal line pattern (scan moiré). It shows itself as wavy patterns on the screen and becomes more noticeable as monitor resolution increases. Since the video signal varies continuously, little can be done about video moiré. Scan moiré depends on the horizontal scanning frequency and can be alleviated by appropriate choice of frequency. Autoscan (MultiSync) monitors, which operate over a range of scanning frequencies, may sometimes exhibit moiré in certain video modes. MPR See Electromagnetic radiation standards. MultiSync monitor See Autoscan monitor. RETURN TO TOP OF THE PAGE N Non-interlaced See Interlaced/non-interlaced. RETURN TO TOP OF THE PAGE O OSD (On Screen Display) The feature that allows an end user to adjust screen performance and parameters of monitors directly through an on-screen instruction window. See CustoMax in CrystalClear section. Overscan The practice in which areas without useful video information are scanned outside the visible screen area in order to make maximum use of the screen for display of active video information. This practice is occasionally necessary because some video cards generate a video pattern that is smaller than the visible file:///D|/rita/LF2/LF2/LFa1/multi_manual/english/GLOSSARY/GLOSSARY. HTM (9 of 18) [8/29/2001 2:55:48 PM] Glossary screen area, resulting in an image that is smaller (and less legible) than it needs to be. RETURN TO TOP OF THE PAGE P Parallelogram Distortion See Geometric distortion. Phosphor Generic name for the class of substances that exhibit luminescence. To produce a picture on screen, phosphors are deposited on the inner surface of the picture-tube screen and excited into luminescence by the electron beam. Typical examples of phosphors are P22 medium short-persistence phosphor and EBU high-color-saturation phosphor. Pin-cushion Distortion See Geometric distortion. Pixel Abbreviation for picture element, the smallest element of the picture that can be displayed on the screen. The smaller the pixel size, the better the resolution of the monitor. Pixel size is determined by the size of the electron spot on the screen and not necessarily by the phosphor dot pitch (the size of the triad). Thus, a monitor with a large electron spot covering several triads can exhibit poor resolution even though its dot pitch is small. Pixel frequency The number of pixels that can be written in a video line per second. Pixel rate See pixel frequency Plug-and-Play See DDC.

Refresh rate See Vertical scanning frequency. Resolution The number of pixels that can be displayed on the screen. The resolution is specified as the number of pixels in a line multiplied by the number of horizontal lines. See also video graphic adapter. Rotation function The feature that allows users to adjust the whole screen rotating to be horizontal. Because of the magnetic field of earth, the screen of monitor will be tilt when the screen faces toward the different direction.

HTM (11 of 18) [8/29/2001 2:55:48 PM] Glossary Anti-Static coatings Due to bombardment by beam electrons, monitor screens become electrically charged when in use. Electrically charged screens surfaces can attract dust particles. [. . . ] Adjustments of the controls discussed there may save you a service call. TO GET WARRANTY SERVICE IN U. S.
