LCD Technology may experience a phenomenon known as Image Persistence Image Persistence occurs when a residual or ghost image of a previous image remains visible on the screen Unlike CRT monitors LCD monitors 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 displaying moving images and using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use Image is unstable unfocused or swimming is apparent Signal cable should be completely attached to the computer 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 re adjusted e 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 colour can be seen Power Switch should be in the ON position and power cord shou
