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 today’s complex computing
environments.
The LCD1280 features a 13-inch (diagonal viewable
image size), active matrix, true-color, thin-film-transistor,
liquid crystal display to provide superior display performance 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-
formance necessary for today’s sophisticated Windows,
Macintosh, Silicon Graphics, Sun and other workstation
applications.
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.
Analog Interface
Because the LCD1280 accepts an analog input, a graphics
card with digital output is not required. The same graphics boar
d 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.
Reduced Footprint
The LCD1280 monitor offers nearly the same active
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 con
cern.
Introduction

LCD1280 10/29/99 9:25 AM Page 3
Low Power Consumption
The LCD1280 has been designed with NEC’s IPM™ (Intelligent
Power Manager) System. When utilized with an Energy Star
system or video card, the LCD1280's IPM System is an innovative power saving utility that complies with both the EPA’s
Energy Star requirements and Europe’s NUTEK’s power management requirements.
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, environmental protection, reduced emissions and reduced air
conditioning costs of the work environment.
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 monitor’s horizontal and
vertical SYNC signals, the monitor can be prompted into the
different IPM modes. The following is the description of the
LED indicator for the IPM power saving modes:
Mode LED Indicator Power Consumption
ON Green Typical: 45 watts
Stand By & Suspend Amber
Typical: Less than 8 watts
Power Switch, OFF No Light No Power Used
ErgoDesign™
The LCD1280 utilizes NEC’s ErgoDesign philosophy to
make the panel more comfortable and easy to use. The
panel’s power and brightness control are positioned within
easy reach, and the tilt base adjusts to each individual’s
preferred angle of vision. The LCD1280 monitor’s cabinet
design and aesthetics look good from all angles.
Reduced Emissions
Incorporating NEC’s own Reduced Magnetic Field™ technology, 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.

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 monitor’s 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.
• Handle with care when transporting.
• Use the monitor in a clean and dry area.
• Clean the LCD surface with a lint-free, non-abrasive cloth and a nonalcohol, 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 supports high resolution graphics (1280 x 1024), 24-bit color
(16.7M colors), delivers an analog output, and which has
a high resolution pixel frequency of 107.5 MHz ± 50 ppm
or 107.352 MHz ± 50 ppm. Silicon Graphics’ INDIGO2
workstation does not require a graphics card. (For a current
list of compatible platforms please call NEC’s FastFacts at
1-800-366-0476 and request document #52301280).
To attach the monitor to your system, follow these instructions:
1. Turn off the power to the monitor and computer.
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.
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
SGI’s INDIGO2, a timing of 107.352 MHz applies (Mode 2).

H-SEL Pixel Frequency (DOT clock):

5. Make sure the appropriate BNC cable is used. Should the
graphics adapter require a connector other than the 15 pin
mini D-sub male included with the monitor, please call NEC
at (800) 820-1230. Connect cable to system.
6. Connect BNC cables as follows according to the input video
mode selected above. (Note: incorrect cable connections
may result in irregular operation, damage display quality/
components of LCD module, and/or shorten the
module’s life.)
Input Video Mode H/CS VS R G/SYNC B
Separate Sync OOOOO
Composite Sync OXOOO
Sync on Green XXOOO
O - BNC connector is utilized; X - BNC connector is not utilized
Connect the red BNC cable to the BNC connector on the
monitor labeled R. The green BNC cable should be connected to the BNC connector on the monitor labeled G. The
blue BNC cable should be connected to the BNC connector
on the monitor labeled B. If you have a fourth BNC connector (Composite Sync), connect it to the BNC connector on the
monitor labeled H/CS. If you have a fifth BNC connector
(Vertical Sync), connect it to the BNC connector on the monitor labeled VS. Please see Appendix 1 for pin assignments.
7. Connect one end of the power cable to the LCD1280
monitor and the other end to the power outlet.
8. Turn on the monitor and the computer.
Note: If the settings and connections were made properly,
the LED on the front of the LCD1280 will show green.
If the LED displays an amber color, the monitor is not receiving the appropriate input. Please make certain that the
above settings were made properly. If the LED continues
to display an amber color or the monitor is not displaying
a stable image, please refer to the Troubleshooting section
of this manual.
