No picture
• The signal cable should be completely connected to the display card/computer.
• The display card should be completely seated in its slot.
• Power Button and computer power switch should be in the ON position.
• Check to make sure that a supported mode has been selected on the display
card or system being used. (Please consult display card or system manual to
change graphics mode.)
• Check the monitor and your display card with respect to compatibility and
recommended settings.

Power Button does not respond
• Unplug the power cord of the monitor from the AC outlet to turn off and reset the
monitor, or simultaneously press the RESET and Power buttons.
Image persistence
• Image persistence is when a "ghost" of an image remains on the screen even
after the monitor has been turned off. Unlike CRT monitors, LCD monitors' image
persistence is not permanent. To alleviate image persistence, turn the monitor off
for as long as an image was displayed. If an image was on the monitor for one
hour and a "ghost" of that image remains, the monitor should be turned off for
one hour to erase the image.
NOTE: As with all personal display devices, NEC Technologies recommends using a
screen saver at regular intervals whenever the screen is idle.
