Introduction  
formance necessary for todays sophisticated Windows,  
Contents of Package  
Macintosh, Silicon Graphics, Sun and other workstation  
applications.  
Congratulations on your purchase of the NEC LCD1280  
True Color monitor!  
In addition to offering support for VGA graphics mode  
(640 x 480), the LCD1280 supports WS high resolution  
mode (1280 x 1024). The LCD1280 automatically detects  
and changes between WS high resolution mode and VGA  
graphics mode. The LCD1280 can display an infinite  
number of colors in its high resolution mode.  
Included with your LCD1280 monitor are the following items:  
1. NEC LCD1280 (Model #LA-1331JSW) True Color monitor.  
2.AC power cable.  
3.Video signal cable (15 pin mini D-sub male to 5  
branched BNC male).  
4.Users Manual.  
Analog Interface  
Remember to save the original box and packing materials  
to transport or ship this monitor.  
Because the LCD1280 accepts an analog input, a graphics  
card with digital output is not required. The same graph-  
ics board can be used to drive the LCD1280 or a standard  
CRT monitor. The analog interface also provides the LCD  
with its true-color capability. Unlike digital panels, the  
LCD1280 is able to display a continuous spectrum of  
“true” colors.  
Introduction to the NEC LCD1280  
True Color Monitor  
The LCD1280 monitor provides superior display  
performance, a reduced footprint and the flexibility and  
adaptability required by todays complex computing  
environments.  
Reduced Footprint  
The LCD1280 monitor offers nearly the same active  
The LCD1280 features a 13-inch (diagonal viewable  
image size), active matrix, true-color, thin-film-transistor,  
liquid crystal display to provide superior display perform-  
ance with a reduced footprint. Less than seven inches in  
depth, the LCD1280 monitor is ideal for environments with  
space and weight constraints that require superior image  
quality. The LCD1280 also delivers the outstanding per-  
display size as a conventional 15-inch CRT (13.8” diagonal  
viewable image size) at 40% of the depth and 30% of the  
weight. With a depth of less than seven inches, the reduced  
footprint of the LCD1280 provides the ideal solution for  
applications requiring a large display and high resolution but  
where space and weight are of particular concern.

Introduction  
Low Power Consumption  
The LCD1280 has been designed with NECs IPM™ (Intelligent  
Power Manager) System. When utilized with an Energy Star  
system or video card, the LCD1280's IPM System is an innova-  
tive power saving utility that complies with both the EPAs  
Energy Star requirements and Europes NUTEKs power man-  
agement requirements.  
different IPM modes. The following is the description of the  
LED indicator for the IPM power saving modes:

Power Consumption  
Typical: 45 watts  
Stand By & Suspend  
Power Switch, OFF  
Amber  
No Light  
Typical: Less than 8 watts  
No Power Used  
With a maximum power consumption of only 50 watts in  
its on mode, the LCD1280 monitor consumes up to 50%  
less power and emits less heat than conventional CRTs.  
In its power saving mode, the LCD1280 consumes less  
than 8 watts. All this translates into energy savings, envi-  
ronmental protection, reduced emissions and reduced air  
conditioning costs of the work environment.  
ErgoDesign™  
The LCD1280 utilizes NECs ErgoDesign philosophy to  
make the panel more comfortable and easy to use. The  
panels power and brightness control are positioned within  
easy reach, and the tilt base adjusts to each individuals  
preferred angle of vision. The LCD1280 monitors cabinet  
design and aesthetics look good from all angles.  
The LCD1280 monitor follows the Video Electronics Standard  
Association (VESA) approved DPMS power-down signaling  
method. VESA’s Display Power Management Signaling (DPMS)  
method which is endorsed by the EPA is the power-down  
process a system should use to communicate to the monitor to  
save power. Power-down functions can only be utilized with  
an Energy Star system or video card which adheres to the  
VESA DPMS standard. By using the monitors horizontal and  
vertical SYNC signals, the monitor can be prompted into the  
Reduced Emissions  
Incorporating NECs own Reduced Magnetic Field™ tech-  
nology, the LCD1280 has minimal field emissions and  
follows the strictest magnetic field, alternating electric field  
and electro-static recommendations of the Swedish Board  
for Technical Accreditation, or SWEDAC (previously  
known as MPR, National Board for Measurement and  
Testing). The LCD1280 conforms to SWEDAC MPR  
1990:8 (MPR II) Testing Methods for Emissions. These  
standards are the most restrictive guidelines in the world.

list of compatible platforms please call NECs FastFacts at  
1-800-366-0476 and request document #52301280).  
Recommended Use  
For optimum performance, please note the following when  
setting up and using the LCD1280 color monitor:  
• The optimum monitor position is facing away from direct sunlight.  
• Match the monitors brightness to the ambient room brightness.  
The brightness control should be adjusted to a point where the

overall background area just begins to disappear.  
• If possible, use a white background and black text to ease eye  
strain.  
• Do not place any heavy objects on the power cord. Damage  
to the cord may cause shock or fire.  
2. If necessary, install the graphics card and drivers.  
Determine the pixel frequency (DOT clock) output and the  
SYNC method used by the graphics card or system. For  
more information, refer to the graphics card or system manual  
or the FastFacts document referred to above.  
• Handle with care when transporting.  
3. Make sure the H-SEL switch on the rear of the panel  
is positioned to the appropriate pixel frequency (if you are  
not sure, refer to the board manual or documents). Under  
most cases, a timing of 107.5 MHz will apply (Mode 1). For  
SGIs INDIGO2, a timing of 107.352 MHz applies (Mode 2).  
• Use the monitor in a clean and dry area.  
• Clean the LCD surface with a lint-free, non-abrasive cloth and a non-  
alcohol, neutral, non-abrasive cleaning solution or glass cleaner.  
• For optimum performance, allow 20 minutes for warm-up.  
• Avoid displaying fixed patterns on the monitor for extremely long  
periods of time to avoid after-image effects.

Connection to Graphics Cards using BNC cables  
The NEC LCD1280 color monitor complements a host of  
computing platforms. However, because the LCD1280 is a  
high resolution, full color analog monitor, it may require  
the use of a graphics card (sometimes referred to as a  
video card, video adapter or graphics board) that sup-  
ports high resolution graphics (1280 x 1024), 24-bit color  
(16.7M colors), delivers an analog output, and which has

Troubleshooting/Support  
Problem  
Check These Items  
No Picture  
• The signal cable should be completely connected to the video card/computer.  
• The video card should be completely seated in its slot.  
Power Switch and computer power switch should be in the ON position.  
• Check BNC connectors to make certain that each connector has been attached correctly.  
• Check H-SEL Switch and SYNC Switch to make certain that they are in the  
correct position according to the Installation section of this manual.  
Image is unstable or swimming  
is apparent  
• Signal cable should be completely attached to the computer.  
• Check the monitor and your video card with respect to compatability and recommended  
signal timings (Please see FastFacts document #52301280 and Appendix 2).  
• Check the SYNC Switch and H-SEL Switch for their correct position.  
LED on the monitor is not lit  
(no green or amber color can  
be seen)  
• Power Switch should be in the ON position and the power cord should be connected.  
• Make certain the computer is not in a Power-Saving mode (touch the keyboard or mouse).  
Picture is not focused or  
jitter is present  
• Use WS Clock Delay Adjust (H-C) or VGA Clock Delay Adjust (V-C) to focus  
display. When the display mode will be changed, the clock settings may need to be  
re-adjusted.  
Display image is not centered  
• Use WS and VGA horizontal and vertical adjustment controls located on the rear of the  
panel to adjust centering.
