MMoiré effectA 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 showsitself as wavy patterns on the screen and becomes more noticeable as monitor resolution increases. Sincethe video signal varies continuously, little can be done about video moiré. Scan moiré depends on thehorizontal 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 incertain video modes.MPRSee Electromagnetic radiation standards.MultiSync monitorSee Autoscan monitor.RETURN TO TOP OF THE PAGENNon-interlacedSee Interlaced/non-interlaced.RETURN TO TOP OF THE PAGEOOSD (On Screen Display)The feature that allows an end user to adjust screen performance and parameters of monitors directlythrough an on-screen instruction window. See CustoMax in CrystalClear section.OverscanThe practice in which areas without useful video information are scanned outside the visible screen area inorder to make maximum use of the screen for display of active video information. This practice isoccasionally necessary because some video cards generate a video pattern that is smaller than the visibleGlossaryfile:///D|/rita/LF2/LF2/LFa1/multi_manual/english/GLOSSARY/GLOSSARY.HTM (9 of 18) [8/29/2001 2:55:48 PM]
