Introduction
Congratulations on your purchase of the MultiSync P750 colour Monitor!
The MultiSync P750 monitor includes the CROMACLEAR CRT,
Microsoft’s Plug and Play, NEC’s ErgoDesign properties, the On
Screen Manager (OSM), as well as all the unique features you expect
from MultiSync Monitors.
The MultiSync technology provides you with automatic compatibility
with multiple operating platforms and a vast array of graphics standards
allowing resolution upgrades without upgrading the monitor.
The MultiSync P750 monitor strictly follows ErgoDesign guidelines
featuring enhanced human ergonomics (human and earth condition).
The goal of ErgoDesign is to maximise the comfort and productivity of
the end user. ErgoDesign parallels the strict European standards of
power management and reduced emissions. In addition our monitor is
designed to be recyclable.
CROMACLEAR CRT Technology
The MultiSync P750 monitor features NEC’s exclusive CROMACLEAR
CRT (Cathode Ray Tube), the latest advancement in display technology.
This technology, patented by NEC, delivers images with more clarity
than found in traditional dot-trio CRTs. Unlike the conventional shadow
mask with phosphor dots, CROMACLEAR CRT has ellipse-shaped
phosphors. Screen images have higher definition, color saturation and
more depth and dimension.
The CROMACLEAR CRT has Dynamic Beam Focus which provides
precise and continuous focus adjustment of the electron beams.
Dynamic beam focus provides optimum image quality, even to the far
edges of the screen. You will notice a significant difference in the focus
and clarity of the image for realistic text, graphics and video.
The OptiClear Surface of the P750 CRT dramatically reduces the
reflection of ambient illumination and glare resulting in greatly
improved user comfort and productivity. This multilayered screen
coating increases the contrast without sacrificing the focus level, clarity
or brightness.
Introduction E - 1

A high contrast screen with a .25 mm mask pitch sharpens image clarity
and enhances detail. On-screen information is easier to read.
The flat square CRT technology reduces image distortion and glare.
Plug and Play
Plug and Play is the new Microsoft®solution with Windows®95 to
provide automatic peripheral connections without confusing and
time-consuming setup. When used with a Plug and Play compatible system
and video card, the MultiSync P750 monitor automatically tells the system
its identification and capabilities. The system will then select its highest
resolution and refresh rate to take advantage of your MultiSync monitor.
D-SUB/BNC Selection
Up-front BNC/D-SUB Selection Button on the monitors allows you to
connect two systems to one MultiSync P750 monitor. This front panel
button allows you to select a system. Use the MultiCable with the
D-Sub connector to display the video of one system, and use the BNC
inputs to display the video of another system. Using the same P750
monitor, you can easily select either one of the systems by simply
pushing the BNC/D-SUB Button.
ErgoDesign
The MultiSync ErgoDesign features enhance human ergonomics
(human and earth conditions). MultiSync monitor’s ErgoDesign will
improve the working environment, protect the health of the user and
save money. ErgoDesign parallels the strict European standards of
power management and reduced emissions:
–automatic display power-down (also known as NUTEK
specification 803299)
–emission characteristics (stricter than those referred to as
reduced electromagnetic fields as recommended by MPR II
and, for JC-1744UMB, also by TCO)
–safety (EN 60950)
E - 2 Introduction

MultiSync monitors comply with these standards by offering IPM
System power management and Reduced Magnetic Field technology.
Power Manager
IPM (Intelligent Power Manager) System is an innovative power-saving
utility that complies with both the EPA’s Energy Star requirements and
Europe’s TCO NUTEK’s power management requirements. Energy Star
products use less than 30 watts when in the main power saving mode. The
NUTEK specification 803299 requires automatic power down to less than
30 watts in the suspend mode and less than 8 watts in the off mode.
When in the maximum power-down mode, the MultiSync P750 monitor
will consume approximately 10% of the total power drawn under
normal operation. This innovation adds up to 90% energy savings,
longer monitor life, environmental protection, reduced emissions and
reduced air conditioning costs of the work environment. The IPM
System increases the monitor’s life and saves energy and costs by
powering down when not in use.
MultiSync monitors follow the Video Electronics Standard Association
(VESA) approved DPMS power-down signalling method. VESA’s
Display Power Management Signalling (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
be utilised only 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:
Introduction E - 3

Mode LED Indicator Power Saving
On Green None
Stand By Green Minimum (Quickest Recovery)
Suspend Yellow Moderate (< 20 Watts, Moderate
Recovery)
Off (IPM Mode) Orange Maximum (< 5 Watts, Slow Recovery)
Off (Power
Switch, Off) No Light No Power Used (Fully Off)
Reduced Emissions
The P750 monitor incorporates Reduced Magnetic Field technology designed
to reduce magnetic and alternating electric field emissions and static
electricity. NEC’s monitors follow the strictest magnetic field, alternating
electric field, and electrostatic recommendations of the Swedish Board for
Technical Accreditation, or SWEDAC (previously known as MPR, National
Board for Measurement and Testing). The JC-1744UMB follow the
recommendations of the TCO which specify maximum recommended values
of electric and magnetic fields.
Multiple Frequency Technology
Multiple Frequency Technology automatically adjusts the monitor to the
video card’s scanning frequency, displaying the resolution you desire. The
MultiSync P750 color monitor also supports multiple operating platforms
such as PC compatible, Macintosh family and workstation systems.
Increased refresh rates at all resolutions provide a flicker-free image.
The clearer image is easier on your eyes and extends your viewing time.
A wide range of graphics standards of PC and Macintosh computers,
including VESA standards, is supported by the MultiSync P750 color
monitor including:

NOTE: Some system may not support all modes listed.
Horizontal and vertical FullScan capability can increase the display size
of a variety of video modes to the edges of the monitor bezel. The
FullScan capability allows you to use the entire screen area in most
resolutions, significantly expanding image size.
