1. Precautions and Safety Notices

1. Appropriate Operation

(1) Turn off the product before cleaning.
(2) Use only a dry soft cloth when cleaning the LCD panel surface.
(3) Use a soft cloth soaked with mild detergent to clean the display housing.
(4) Use only a high quality, safety approved AC/DC power cord.
(5) Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.
(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.
(7) Do not touch the LCD panel surface with sharp or hard objects.
(8) Do not place heavy objects on the LCD display, video cable, or power cord.
(9) Do not use abrasive cleaners, waxes or solvents for your cleaning.
(10) Do not operate the product under the following conditions:

- Extremely hot, cold or humid environment.

- Areas containing excessive dust and dirt.

- Near any appliance generating a strong magnetic field.

- In direct sunlight.

2. Caution

No modification of any circuit should be attempted. Service work should only be performed after you are thoroughly familiar

with all of the following safety checks and servicing guidelines.

3. Safety Check

Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit, the voltage is

exposed in such areas as the associated transformer circuits.

4. LCD Module Handling Precautions

4.1 Handling Precautions

(1) Since front polarizer is easily damaged, pay attention not to scratch it.
(2) Be sure to turn off power supply when connecting or disconnecting input connector.
(3) Wipe off water drops immediately. Long contact with water may cause discoloration or spots.
(4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
(5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
(6) Since CMOS LSI is used in this module, take care of static electricity and ensure human earth when handling.
(7) Do not open or modify the Module Assembly.
(8) Do not press the reflector sheet at the back of the module in any direction.
(9) In the event that a Module must be put back into the packing container slot after it was taken out of the

container, do not press the center of the CCFL Reflector edge. Instead, press at the far ends of the
CFL Reflector edge softly. Otherwise the TFT Module may be damaged.

(10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate or tilt the Interface

Connector of the TFT Module.

(11) After installation of the TFT Module into an enclosure (LCD monitor housing, for example), do not twist or

bend the TFT Module even momentarily. When designing the enclosure, it should be taken into consideration
that no bending/twisting forces may be applied to the TFT Module from outside. Otherwise the TFT Module
may be damaged.

(12) The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local

ordinances or regulations for disposal.

(13) The LCD module contains a small amount of materials having no flammability grade. The LCD module

should be supplied with power that complies with the requirements of Limited Power Source
(IEC60950 or UL1950), or an exemption should be applied for.

(14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950

or UL1950). Do not connect the CCFL to a Hazardous Voltage Circuit.

Correct methods : Incorrect Methods :
Only touch the metal-frame of the panel or the front cover
of the monitor.
Do not touch the surface of the polarizer .

Surface of the panel is pressed by fingers & this may
cause “ MURA “

Take out the monitor with cushion Take out the monitor by grasping the LCD panel.

That may cause “ MURA“.

Do the following to adjust the screen image:

1. To display the Main Menu, press button [1].

NOTE: All OnView 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 you want to adjust, press S or T to scroll up or down the Main Menu.

3. After the control is selected, press button [2]. A control screen like the one shown below

appears.

The command line at the bottom of the
control screen tells what to do next from
this screen. You can toggle between control
screens, adjust the selected option, or exit
the screen.

4. To adjust the control, press the up S or down T buttons.

5. To save the adjustments and exit the menu, press button [1] twice.

The following tips may help you optimize your display:

• Adjust your computer's graphic card so that it outputs a video signal 1280 x 1024 @ 60Hz
to the LCD display. (Look for instructions on “changing the refresh rate” in your graphic
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.)

Information displays the timing mode (video signal input) coming from the
graphics card in your computer, the LCD model number, the serial number, and
the ViewSonic website URL. See your graphic cards 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 Sub-menu

H. Size (Horizontal Size) adjusts the width of the screen image.

H./V. Position (Horizontal/Vertical Position) moves the screen image left or

screens.

Resolution Notice allows you to enable or disable this notice.

If you enable the Resolution Notice shown above and your computer is set at a
resolution other than 1280 x 1024, the following screen appears.

OSD Position allows you to move the on-screen display menus and control
screens.

OSD Timeout sets the length of time the on-screen display screen is displayed.
For example, with a “30 second” setting, if a control is not pushed within 30
seconds, the display screen disappears.

OSD Background On/Off allows you to turn the On-Screen Display
background On or Off.

2. Flash Memory

The F29C51001T/F29C51001B is a 1 Megabit, 5.0 Volt-only Flash Memory organized as 131,072
bytes of 8 bits each. This device is designed to use a 4.7 Volt to 5.3 Volt power supply to perform
in-system programming.
The 1 Megabit memory array is divided into thirty-two uniform blocks of 4 Kbytes each for data and/or
code storage.

The block architecture allows users to flexibly make chip erase or block erase operation. The block
erase feature allows a particular block to be erased and reprogrammed without affecting the data in
other blocks. After the device performs chip erase or block erase operation, it can be reprogrammed on
a byte-by-byte basis.

3. GM5120

The gm5116/26 is a graphic processing IC for Liquid Crystal Display (LCD) monitors at XGA/SXGA
resolution. It provides all key IC functions required for the highest quality LCD monitors. On-chip
functions include a high-speed triple-ADC and PLL, Ultra-Reliable DVI
zoom and shrink scaling engine, an on-screen display (OSD) controller, digital color controls and an
on-chip microcontroller (OCM). With this level of integration, the gm5116/26 devices simplify and
reduce the cost of LCD monitors while maintaining a high-degree of flexibility and quality.

4. LVDS (THC63LVDM83A)

The THC63LVDM83A transmitter converts 28 bits of CMOS/TTL data into LVDS (Low Voltage
Differential Signaling) data stream. A phase-locked transmit clock is transmitted in parallel with the
data streams over a fifth LVDS link. The HC63LVDM83A can be programmed for rising edge or
falling edge clocks through a dedicated pin. The THC63LVDF84A receiver converts the LVDS data
streams back into 28 bits of CMOS/TTL data with falling edge clock. At a transmit clock frequency of
85MHz, 24 bits of RGB data and 4 bits of LCD timing and control data (HSYNC, VSYNC, CNTL1,
CNTL2) are transmitted at a rate of 595 Mbps per LVDS data channel.
