¥Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.

Image Persistence

¥Please be aware that LCD Technology may experience a phenomenon known as Image Persistence. Image Persistence occurs 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 DISPLAY SOLUTIONS 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.

¥Use the OSD Image Adjust controls to focus and adjust display by increasing or decreasing the fine total. When the display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.

¥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.
