1. Precautions and Safety Notices
1.1 safety precautions
round principle that a user’s safety comes first. However, improper use
WARNINGS
should be operated only at the correct power sources indicated on the label on the rear end of the monitor.
If you’re unsure of the power supply in your residence, consult you local dealer or power company.
-serviceable parts. This monitor should only be repaired by
monitor cabinet. There is high-voltage parts inside that may cause electric shock to human bodies,
nly in a clean, dry environment. If it gets wet, unplug the power cableimmediately and consult your
-ammonia based
oth, not directly onto the glass screen.
1.2 Product safety notice
chassis have special safety visual inspections and the protection afforded
by them cannot necessarily be obtained by using replacement components rated for higher voltages, 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.
1.3 Service notes
When replacing parts or circuit boards, clamp the lead wires around terminals before soldering.
When replacing a high wattage resistor(more than 1W of metal oxide film resistor) in circuit board, keep the resistor
about 5mm away from circuit board.
Keep wires away from high voltage, high temperature components and sharp edges.
Keep wires in their original position so as to reduce interference.
Usage of this product please refer to also user’s manual.

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.)

Control Explanation
Auto Image Adjust automatically sizes, centers, and fine tunes the video signal
to eliminate waviness and distortion. Press the [2] button to obtain a sharper
image.
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.
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, press and.
Important: If you select RECALL from the Main Menu when the product is set
to a Preset Timing Mode, colors return to the 6500K factory preset.

Control Explanation
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 1366 x 768 @ 60Hz (recommended) means that the resolution is
1366 x 768 and the refresh rate is 60 Hertz.
Manual Image Adjust displays the Manual Image Adjust menu.
H./V. Position (Horizontal/Vertical Position) moves the screen image left or
right and up or down.
H. Size (Horizontal Size) adjusts the width of the screen image.
Fine Tune sharpens the focus by aligning text and/or graphics with pixel
boundaries.
NOTE: Try Auto Image Adjust first.
Sharpness adjusts the clarity and focus of the screen image.
Aspect ratio Selects the image size for 4:3 and full screen.
ECO Mode provides the lower power consumption by reducing the brightness.
Standard: The default brightness setting
Optimize: Decreases the brightness by 25 %
Conserve: Decreases the brightness by 50 %
NOTE: When the ECO Mode is set to "Optimize" or "Conserve", the
Brightness, Contrast, and Dynamic Contrast cannot be adjusted.
