and more depth and dimension.  
color monitor! The MultiSync P750 monitor delivers superior  
image quality for all your demanding application needs. The  
MultiSync P750 monitor delivers the power you need for today’s  
high-end applications. The MultiSync P750 monitor features the  
latest advancements in display technology, allowing you to take  
advantage of all your sophisticated applications.  
The CROMACLEAR CRT has dual Dynamic Beam Focus which  
provides precise and continuous focus adjustment of the electron  
beams. Dual Dynamic beam focus provides optimum image  
quality, even to the far edges of the screen. You will notice the  
significant difference CROMACLEAR makes through enhanced  
image clarity, depth and definition for realistic text, graphics and  
video.  
The MultiSync P750 monitor includes many features designed  
to give you the extra functionality and performance that you  
need in your monitor. NEC’s newest feature, the CROMACLEAR  
CRT, is offered in the MultiSync P750. Other features that enhance  
the MultiSync P750 monitor’s performance are dual Dynamic  
Beam Focus, On-Screen Manager, Microsoft’s Plug and Play  
compatibility and ErgoDesign® features.  
The OptiClear® Screen Surface of the MultiSync P750 CRT  
dramatically reduces the reflection and glare of ambient lighting  
resulting in greatly improved user comfort and productivity. This  
multilayered screen coating increases the contrast without  
sacrificing the focus level, clarity or brightness.  
Screen Technology  
CROMACLEAR CRT  
The MultiSync P750 features NEC’s exclusive CROMACLEAR CRT  
(Cathode Ray Tube), the latest advancement in display technol-  
ogy. The CROMACLEAR CRT, patented by NEC, delivers images  
with more clarity than found in traditional dot-trio or aperture  
grille CRTs. Unlike the conventional shadow mask with phosphor  
A high contrast screen with a 0.25 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  
When in the maximum power-down mode, the MultiSync  
P750 monitor will consume approximately 10% of the total  
power drawn under normal operation, which follows the Video  
Electronics Standard Association (VESA) approved DPMS  
power-down signaling method. This innovation adds up to 90%  
energy savings, longer monitor life, environmental protection,  
reduced emissions and reduced air conditioning costs of the  
work environment.  
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  
system and display card, the MultiSync® P750monitor automati-  
cally 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.  
ErgoDesign® Features  
Reduced Emissions  
ErgoDesign features enhance human ergonomics (human and  
earth conditions), which will improve the working environment,  
protect the health of the user and save money. ErgoDesign  
features parallel the strict European standards of power manage-  
ment and reduced emissions and the requirements laid down in  
the MPR II.  
The MultiSync P750 monitor incorporates Reduced Magnetic  
Fieldtechnology designed to reduce magnetic and alternating  
electric field emissions and static electricity. NEC MultiSync  
monitors follow 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) and TCO  
(excluding alternating electric fields) which specify maximum  
recommended values of electric and magnetic fields.  
Power Manager  
IPM(Intelligent Power Manager) System is an innovative  
power-saving feature that complies with both the EPA’s Energy  
Star requirements and Europe’s TCO NUTEK 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.  
Multiple Frequency Technology  
Multiple Frequency Technology automatically adjusts the  
monitor to the display card’s scanning frequency, displaying the  
resolution you desire. The MultiSync P750 monitor also supports  
multiple operating platforms such as PC compatible, Macintosh  
family and workstation systems.

FOLLOWING WHEN YOU POSITION THE MONITOR:  
Rest your eyes periodically by focusing on an object at least 20 feet  
away. Blink often.  
Position the monitor at a 90° angle to windows and other light  
sources to minimize glare and reflections. Adjust the monitor tilt so  
that ceiling lights do not reflect on your screen.  
If reflected light makes it hard for you to see your screen, use an anti-  
glare filter.  
Clean your monitor regularly. Use a lint-free, non-abrasive cloth and  
a non-alcohol, neutral, non-abrasive cleaning solution or glass  
cleaner to minimize dust.  
Adjust the monitor’s brightness and contrast controls to enhance  
readability.  
Use a document holder placed close to the screen.  
Position whatever you are looking at most of the time (the screen or  
reference material) directly in front of you to minimize turning your  
head while you are typing.  
Get regular eye checkups.
