Image Persistence

¥Image persistence is when a residual or ÒghostÓ image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitorsÕ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.

NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display recommends using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.

Message “OUT OF RANGE” is displayed (screen is either blank or shows rough images only)

¥Image is displayed only roughly (pixels are missing) and OSM warning ÒOUT OF RANGEÓ is displayed: Either signal clock or resolution is too high. Choose one of the supported modes.

¥OSM warning ÒOUT OF RANGEÓ is displayed on a blank screen: Signal frequency is out of range. Choose one

of the supported modes.

¥Use the OSM Image Adjust controls to focus and adjust display by

increasing or decreasing the fine total. When the display mode is changed, the OSM Image Adjust settings may need to be readjusted.

¥Check the monitor and your display card with respect to compatibility and recommended signal timings.

¥If your text is garbled, change the video mode to non-interlace and use 60Hz refresh rate.

LED on monitor is not lit (no green or amber color can be seen)

¥ Power Switch should be in the ON position and power cord should be connected.

Display image is not sized properly

¥Use the OSM Image Adjust controls to increase or decrease the Coarse total.
