Looking at features 9
Looking at features
Your NEC C Series monitor includes a host of features that enhance
performance, ensure your comfort, save power, and let you maximize
your multimedia applications.
Just plug your monitor into a Plug and Play compatible system and
it’s automatically ready to provide optimal performance.
The unlimited color palette and non-glare screen provide a crisp,
detailed image.

10 Looking at features
Your color monitor has the following features:

Plug and Play capability

contemporary ergonomic design

optimized power management system

reduced magnetic field technology

multiple frequency technology

color management with the On-Screen Display (OSD).
Plug and Play
Plug and Play is the Microsoftsolution with Windows95 that
provides automatic peripheral connections without confusing and
time-consuming setup. When used with a Plug and Play compatible
system and display board, the NEC C Series monitor automatically
tells the system its identification and capabilities. The system then
selects its highest resolution and refresh rate to take advantage of the
capabilities of your monitor.
Ergonomic design
The NEC C Series monitor has been designed to enhance human
ergonomics (human and earth conditions), which improve the
working environment, protect the health of the user, and save money.
The color monitor has a tilt/swivel stand so you can adjust it fully for
maximum comfort. It has a high-resolution, flicker-free screen that
can be adjusted using an easy-to-use screen display.
The ergonomic principles used in the monitor design parallel the strict
European standards of power management and reduced emissions and
the requirements in the TCO (Swedish Confederation of Professional
Employees) Agreement on Environmental Labeling 1992.

Looking at features 11
Optimized power management
The NEC C Series monitor uses an optimized power management
system. This is an innovative power-saving feature that complies with
both the EPA’s Energy Star requirements and Europe’s
TCONUTEK’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 monitor consumes
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.
Reduced emissions
The NEC C Series monitor incorporates reduced magnetic field
technology to reduce magnetic and alternating electric field emissions
and static electricity.
NEC monitors follow the strictest magnetic field, alternating electric
field, and electrostatic recommendations of the Swedish Board for
Technical accreditation.
SWEDAC (previously known as MPR, National Board for
Measurement and Testing) specifies maximum recommended values
of electric and magnetic fields. The NEC C Series monitor conforms
to SWEDAC’s MPR 1990:8 (MPR II) methods, which is one of the
most restrictive guidelines in the world.

12 Looking at features
Multiple frequency technology
Multiple frequency technology automatically adjusts the monitor to
the display card’s scanning frequency, displaying the resolution you
desire.
Increased refresh rates at all resolutions provide a flicker-free image
which is easier on your eyes and extends your viewing time.
Depending on the system used, a wide range of graphics standards is
supported by the monitor:

640 x 480 — 60 to 75 Hz vertical refresh

800 x 600 — 56 to 75 Hz vertical refresh

832 x 624 — 75 Hz vertical refresh

1024 x 768 — 60 to 75 Hz vertical refresh (recommended for
optimal display performance)

1280 x 1024 — 60 Hz (maximum resolution based on
horizontal and vertical frequencies only).

Adjusting the monitor 13
Adjusting the monitor
Your NEC C Series monitor features On-Screen Display (OSD)
controls for adjusting monitor settings.
On-Screen Display controls make the monitor easier to use by
providing an on-screen control menu. A touch of the front controls
turns on the OSD, allowing you to move through a menu and adjust
settings.

14 Adjusting the monitor
OSD controls let you adjust the following settings:

horizontal and vertical position

horizontal and vertical size

a convex or concave screen

trapezoid screen shape

color saturation and balance.
You can also use OSD controls to:

return to factory-state settings

degauss (demagnetize) the monitor.
In addition, two manual controls on the front of the monitor allow
you to adjust the brightness and contrast of your monitor screen.
See the following sections for information about using the OSD
controls and the brightness and contrast controls.
Access the On-Screen Display
You can adjust your monitor using a combination of the following
features:

On-Screen Display (OSD) control menu

control panel buttons.
See the following sections for information about using the control
panel buttons and the OSD control menu. The buttons are located
behind the control panel door.
To open the control panel door, press the triangle-shaped icon at the
lower right corner of the door.

Adjusting the monitor 15
Control panel buttons
To use control panel buttons, monitor and computer power must be
on. See the following figure to locate the monitor control panel
buttons.
Locating control panel buttons
Note:
The power lamp shows the operating state of
the monitor. When the lamp is red, the monitor is on, but it
is not getting a signal (either because the signal cable is
not connected or the computer is not on). When the lamp is
green, the monitor is on and is receiving a signal. When the
lamp is orange, the monitor is in power management mode.
Use control panel buttons to bring up the OSD menus and adjust
monitor settings.

16 Adjusting the monitor
On-Screen Display
The On-Screen Display consists of an OSD status display and an
OSD control menu.
The OSD status display shows the horizontal and vertical frequency
and synchronization polarities of the monitor. The status display also
shows the type of display. The OSD status display looks like the
following when you bring it up.
The OSD status display
The OSD control menu is comprised largely of icons. The icons
represent the settings you can access. The OSD control menu is
divided into two areas:

the icon bar

the adjustment bar.
Two rows of icons appear on the top of the OSD control menu in the
icon bar. The adjustment bar appears along the bottom of the menu.
The adjustment bar shows the value of the monitor settings. The OSD
control menu looks like the following menu when you bring it up.
