1. Precautions and Safety Notices
1. SAFETY PRECAUTIONS
This monitor is manufactured and tested on a ground principle that a user’s safety comes first. However,
improper used or installation may cause damage to the monitor as well as to the user.
WARNINGS:
zThis monitor should be operated only at the correct power sources indicated on the label on the rear of the
monitor. If you’re unsure of the power supply in you residence, consult your local dealer or Power
Company.
zUse only the special power adapter that comes with this monitor for power input.
zDo not try to repair the monitor by yourself, as it contains no user-serviceable parts. Only the qualified
technician can repair it.
zDo not remove the monitor cabinet. There are high-voltage parts inside that may cause electric shock to
human bodies.
zStop using the monitor if the cabinet is damaged. Have it checked by a service technician.
zPut your monitor only in a lean, cool, dry environment. If it gets wet, unplug the power cable immediately
and consult your closed dealer.
zAlways unplug the monitor before cleaning it. Clean the cabinet with a clean, dry cloth. Apply
non-ammonia based cleaner onto the cloth, not directly onto the glass screen.
zDo not place heavy objects on the monitor or power cord.
2. PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety visual inspections and the
protection afforded by them cannot necessarily be obtained by using replacement components rated for
higher voltage, wattage, etc. Before replacing any of these components read the parts list in this manual
carefully. The use of substitute replacement parts, which do not have the same safety characteristics as
specified in the parts list, may create shock, fire, or other hazards.
3. SERVICE NOTES
zWhen replacing parts or circuit boards, clamp the lead wires around terminals before soldering.
zKeep wires away from high voltage, high temperature components and sharp edges.
zKeep wires in their original position so as to reduce interference.
zAdjustment of this product please refers to the user’ manual.

4. Handling and Placing Methods
Correct Methods: Incorrect Methods:
Only touch the metal of the LCD panel or the front
cover of he monitor. Do not touch the surface of the
polarizer.
Surface of the LCD panel is pressed by fingers and
that may cause "Mura".
Take out the monitor with cushions. Taking out the monitor by grasping the LCD panel.
That may cause "Mura".

Correct Methods: Incorrect Methods:
Place the monitor on a clean and soft foam pad. Placing the monitor on foreign objects, That could
scratch the surface of the panel or cause "Mura".
The panel is placed facedown on the lap. That may
cause "Mura".

Do the following to adjust the display setting:
1. To display the Main Menu, press button [1].
NOTE: All OSD menus and adjustment screens disappear automatically after about 15
seconds. This is adjustable through the OSD timeout setting in the setup menu.
2. To select a control to adjust, pressSorTto scroll up or down in the Main Menu.
3. After the desired control is selected, press button [2]. A control screen like the one shown
below appears.
4. To adjust the setting, press the upSor downTbuttons.
5. To save the adjustments and exit the menu, press button [1] twice.
The following tips may help you optimize your display:
• Adjust the computer's graphics card so that it outputs a 1280 x 1024 @ 60Hz video signal to
the LCD display. (Look for instructions on “changing the refresh rate” in the graphics card's
user guide.)
• If necessary, make small adjustments using H. POSITION and V. POSITION until the
screen image is completely visible. (The black border around the edge of the screen should
barely touch the illuminated “active area” of the LCD display.)
The line at the bottom of the screen shows
the current functions of buttons 1 and 2:
Exit or select the Brightness control.

Main Menu Controls
Adjust the menu items shown below by using the upSand downTbuttons.
Control Explanation
Auto Image Adjust automatically sizes, centers, and fine tunes the video signal
to eliminate waviness and distortion. Press the [2] button to execute Auto Image
Adjust.
NOTE: Auto Image Adjust works with most common video cards. If this
function does not work on your LCD display, then lower the video refresh rate
to 60 Hz and set the resolution to its pre-set value.
Contrast adjusts the difference between the image background (black level)
and the foreground (white level).
Brightness adjusts background black level of the screen image.
Color Adjust provides several color adjustment modes, including preset color
temperatures and a User Color mode which allows independent adjustment of
red (R), green (G), and blue (B). The factory setting for this product is 6500K
(6500 Kelvin).
sRGB - This is quickly becoming the industry standard for color management,
with support being included in many of the latest applications. Enabling this
setting allows the LCD display to more accurately display colors the way they
were originally intended. Enabling the sRGB setting will cause the Contrast and
Brightness adjustments to be disabled.
9300K - Adds blue to the screen image for cooler white (used in most office
settings with fluorescent lighting).
6500K - Adds red to the screen image for warmer white and richer red.
5400K - Adds green to the screen image for a darker color.

Control Explanation
User Color - Individual adjustments for red (R), green (G), and blue (B).
1. To select color (R, G or B) press button [2].
2. To adjust selected color, pressSorT.
3. When all color adjustments are complete, press button [1] twice.
Information displays the timing mode (video signal input) coming from the
graphics card in the computer, the LCD model number, the serial number, and
the ViewSonic®website URL. See your graphics card’s user guide for
instructions on changing the resolution and refresh rate (vertical frequency).
NOTE: VESA 1280 x 1024 @ 60Hz (recommended) means that the resolution
is 1280 x 1024 and the refresh rate is 60 Hertz.
Manual Image Adjust
H./V. Position (Horizontal/Vertical Position) moves the screen image left or
