save money. Examples include OSD controls for quick and easy image adjustments, tilt base for preferred angle of vision,
small footprint and compliance with MPRII and TCO guidelines for lower emissions.
Plug and Play: The Microsoft solution with the Windows operating system facilitates setup and installation by allowing the
monitor to send its capabilities (such as screen size and resolutions supported) directly to your computer, automatically
optimizing display performance.
IPM (Intelligent Power Manager) System: Provides innovative power-saving methods that allow the monitor to shift to a
lower power consumption level when on but not in use, saving two-thirds of your monitor energy costs, reducing emissions
and lowering the air conditioning costs of the workplace.
Multiple Frequency Technology: Automatically adjusts monitor to the display card’s scanning frequency, thus displaying the
resolution required.
FullScan Capability: Allows you to use the entire screen area in most resolutions, significantly expanding image size.
VESA Standard Mounting Interface: Allows users to connect their AccuSync monitor to any VESA standard third party
mounting arm or bracket. Allows for the monitor to be mounted on a wall or an arm using any third party compliant device.
Environmental Impact (AS171): Annual typical maximum operating carbon footprint of this monitor (world-wide average) is
approximately 20.0 kg (calculated by: rated wattage x 8 hours per day x 5 days a week x 45 weeks per year x Power-to-
Carbon conversion factor - conversion factor is based on OECD publication of global CO2 emissions 2008 Edition).
This monitor has a manufacturing carbon footprint of approximately 13.5 kg.
Environmental Impact (AS191): Annual typical maximum operating carbon footprint of this monitor (world-wide average) is
approximately 21.8 kg (calculated by: rated wattage x 8 hours per day x 5 days a week x 45 weeks per year x Power-to-
Carbon conversion factor - conversion factor is based on OECD publication of global CO2 emissions 2008 Edition).
This monitor has a manufacturing carbon footprint of approximately 15.6 kg.
Note: The manufacturing and operating carbon footprints are calculated by a unique algorithm developed exclusively by NEC
for its monitors.

Troubleshooting
No picture
•The signal cable should be completely connected to the display card/computer.
•The display card should be completely seated in its slot.
•Check front power Switch 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.
•Check the signal cable connector for bent or pushed-in pins.
•Check the signal input.
Power Button does not respond
•Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.
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, but constant images being displayed for a
long period of time should be avoided.
To alleviate image persistence, turn the monitor off for as long as an 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 using a 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 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 60 Hz refresh rate.
Picture is not as bright
•Make sure ECO MODE is turned off.
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 OSD Image Adjust controls to increase or decrease the H.SIZE.
•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.)
No Video
•If no video is present on the screen, turn the Power button off and on again.
•Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
