Introduction

The monitor is a multiple frequency high-resolution color monitor for IBM
compatible PC's or Macintosh and workstation systems. The monitor is
equipped with microprocessor based intelligence and multiple frequency
scanning capability, allowing it to provide maximum compatibility for various
system platforms.

The monitor uses the latest screen technology including a 0.26mm fine
pitch flat square CRT to display crisp text and vivid color graphics with a
max. resolution up to 1600 x 1200/75Hz pixels. Furthermore, it supports
VESA 85Hz modes to provide a flicker free display. The full-function digital
control and On-Screen Display (OSD) system provides easy adjustment of
image geometry and color settings for different display modes with the
precision of a fixed frequency monitor.

The design of the monitor is also ergonomics concerned. In addition to the
friendly controls and user comfort features, the emission level of the elec­tric and magnetic field is kept low to meet the Swedish MPR II and TCO
standards.

The monitor is also equipped with energy saving functions; it is compatible
with the VESA power saving standards. The lowest power consumption is
less than 8 W.

Furthermore, the monitor is built-in the USB (Universal Series Bus) hub. Please
refer to the "USB Kit Content" for the implementation of USB hub.

INTRODUCTION

Feature Highlights

Maximum Compatibility

 Automatically scans all horizontal frequencies between 30kHz and 95kHz,

and all vertical frequencies between 50 Hz and 160 Hz.

 Supports multiple operating platforms such as IBM compatible PC's or

Macintosh computers (with optional adapter).

 Multiple graphic standards with high refresh rates:

640 x 480/160Hz, 800 x 600/150Hz, 1024 x 768/117Hz, 1280 x 1024/
85Hz, 1600 x 1200/75Hz.

 Supports wide range of graphics standards including VGA, Super VGA,

8514/A, XGA, Mac II 13" (640 x 480), Mac 16" (832 x 624), Mac 21"
(1152 x 870), as well as all VESA standards.

Latest Screen Technology

 0.26 mm fine pitch flat square CRT increased the clarity and displays

greater detail.

 Special anti-reflection, anti-glare and anti-static coating of the screen face

provides better focus, contrast and color performance.
 Flat and square screen reduces image distortion and glare.
 Full feature digital control and multi-lingual OSD system allows easy

adjustment of geometry and color. Furthermore the monitor provides

even advanced adjustments like trapezoid, parallelogram, side-pin, pin-

balance, convergence and rotation which allow the user to fine-tune the

screen image.

Ergonomics Concerned

 Electric and magnetic field emissions are kept low to meet the Swedish

MPR II and TCO standard.

 Front user controls allow easy access and comfort to adjust the screen

image to your personal preferences.

 Horizontal and vertical full-scan capabilities allow you to use the entire

screen area in most resolutions.

 A tilt/swivel base for horizontal and vertical adjustments always provides

the optimum viewing angle.

 The BNC/D-15 selection allows user to connect two systems to the moni-

tor and easily select between the two from the front panel switch.

Instant Power Saving Solution

 The monitor is compatible with VESA DPMS (Display Power Management

Signalings) standard which provides four power saving modes by detecting

horizontal and vertical sync signals.

 The monitor consumes 65 W to 120 W depending on the screen contents

in normal operation; when a power saving mode is activated, it con-

sumes less than 15 W in Stand-by mode, less than 15 W in Suspend

mode and less than 8 W in Off mode.

Recommended Use of the Monitor

When setting up and using the monitor, pay special attention to the follow­ing for optimum performance:

 Do not use your monitor against a bright background or where sunlight

or other light sources will shine directly on the screen.

 The monitor should be placed just below eye level (10°~15°) for

optimum viewing.

 Set the monitor's brightness to match the ambient room light.

 For optimum focus, the contrast control should not be set to the maxi-

mum level unless the input signal level is extremely low. Also, the bright-

ness control should be set to a point where the overall background area

just begins to disappear.

 Allow adequate ventilation around the monitor so that the heat from the

monitor can properly dissipate.

 Neither the monitor itself, nor any other heavy objects, should rest on the

power cord. Damage to the power cord can cause fire or electrical shock.

 Keep the monitor away from high-capacity transformers, electrical motors,

or other strong magnetic fields.

 Your monitor should not be used in damp, dusty, or dirty areas.

 Handle your monitor with care when transporting it.

INTRODUCTION

!

CAUTION

 Do not scrape or knock the surface of the CRT with a pen,

a screwdriver and so on.

 Clean the CRT surface with a lint-free, nonabrasive, soft

cloth, do not use a solution or glass cleaner containing
corpuscels like an abrasive, alcohol and an alkaline
solution.

Energy Declaration

This monitor is equipped with a function for saving energy which supports
the VESA Display Power Management Signaling (DPMS) standard. This means
that the monitor must be connected to a computer which also supports the
VESA DPMS standard to fulfill the requirements of the NUTEK specification
803299/94/96. The time settings for switching to a power saving mode are
adjusted from the system unit by software. From the first indication of inac­tivity to power saving position A2 the total time must not be set to more than
70 minutes.
