Preface

Before using this information and the product it supports, please read the following general information.

1. This Service Guide provides you with all technical information relating to BASICCONFIGURATION

decided for Acer’s “global” product offering. To better fit local market requirements and enhance product

competitiveness, your regional office MAY have decided to extend the functionality of a machine (e.g.

add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered

in this generic service guide. In such cases, please contact your regional offices or the responsible

personnel/channel to provide you with further technical details.

2. Please not WHEN ORDERING FRU PARTS, that you should check the most up-to-date information

available on your regional web or channel. If, for whatever reason, a part number change is made, it will

not be noted in the printed Service Guide, for ACER-AUTHORIZED SERVICE PROVIDERS, your Acer

office may have a DIFFERENT part number code to those given in the FRU list of this printed Service

Guide. You MUST use the list provided by your regional Acer office to order FRU parts for repair and

service of customer machines.

WARNING: (FOR FCC CERTIFIED MODELS)

NOTE: this equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against

harmful interference in a residential installation. This equipment generates, uses and can radiate radio

frequency energy, and if not installed and used in accordance with the instructions, may cause harmful

interference to radio communications. However, there is no guarantee that interference will not occur in a

particular installation. If this equipment does cause harmful interference to radio or television reception,

Which can be determined by turning the equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

1. Reorient or relocate the receiving antenna.

2. Increase the separation between the equipment and receiver.

3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

4. Consult the dealer or an experienced radio/TV technician for help.

NOTICE:

1. The changes or modifications not expressly approved by the party responsible for compliance could void

the user’s authority to operate the equipment.

2. Shielded interface cables and AC power cord, if any, must be used in order to comply with the emission

limits.

3. The manufacturer is not responsible for any radio or TV interference caused by unauthorized

modification to this equipment. It is the responsibility of the user to correct such interference.

As an ENERGY STAR® Partner our company has determined that this product meets the ENERGY STAR

WARNING:

To prevent fire or chock hazard, do not expose the monitor to rain or moisture. Dangerously high

voltages are present inside the monitor. Do not open the cabinet. Refer servicing to qualified

personnel only.

PRECAUTIONS

z Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub,

Swimming pool or in a wet basement.

z Do not place the monitor on an unstable trolley, stand, or table. If the monitor falls, it can injure a

person and cause serious damage to the appliance. Use only a trolley or stand recommended by the

manufacture or sold with the monitor. If you mount the monitor on a wall or shelf, use a mounting kit

approved by the manufacture and follow the kit instructions.

z Slots and openings in the back and bottom of the cabinet area provided for ventilation. To ensure

reliable operation of the monitor and to protect it from overheating, be sure these openings are not

blocked or covered. Do not place the monitor on a bed, sofa, rug or similar surface. Do not place the

monitor near or over a radiator or heat register. Do not place the monitor in a bookcase or cabinet

unless proper ventilation is provided.

z The monitor should be operated only from the type of power source indicated on the label. If you are

not sure of the type of power supplied to your home, consult your dealer or local power company.

z The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin. This

plug will fit only into a grounded power outlet as a safety feature. If your outlet does not accommodate

the three-wire plug, have an electrician install the correct outlet, or use an adapter to ground the

appliance safely. Do not defeat the safety purpose of the grounded plug.

z Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will

protect the monitor from damage due to power surges.

z Do not overload power strips and extension cords. Overloading can result in fire or electric shock.
z Never push any object into the slot on the monitor cabinet. It could short circuit parts causing a fire or

electric shock. Never spill liquids on the monitor.

z Do not attempt to service the monitor yourself; opening or removing covers can expose you to

dangerous voltages and other hazards. Please refer all servicing to qualified service personnel.

z To ensure satisfactory operation, use the monitor only with UL listed computers which have

appropriate configured receptacles marked between 100-240V AC, Min. 3.5A.

z The wall socket shall be installed near the equipment and shall be easily accessible.
z For use only with the attached power adapter (output 12V DC) which have UL,CSA listed license

SPECIAL NOTES ON LCD MONITORS

The following symptoms are normal with LCD monitor and do not indicate a problem.

NOTES

z Due to the nature of the fluorescent light, the screen may flicker during initial use. Turn off the Power

Switch and then turn it on again to make sure the flicker disappears.

z You may find slightly uneven brightness in the screen depending on the desktop pattern you use.
z The LCD screen has effective pixels of 99.99% or more. It may include blemishes of 0.01% or less such

as a missing pixel or a pixel lit all of the time.

z Due to the nature of the LCD screen, an afterimage of the previous screen may remain after switching

the image, when the same image is displayed for hours. In this case, the screen is recovered slowly by

changing the image or turning off the Power Switch for hours.

The contrast ratio can be calculated by the following expression and figure below.
Contrast Ratio (CR) = L255 / L0
L255: Luminance of gray level 255

L 0: Luminance of gray level 0
CR = CR (1)

CR (X) is corresponding to the Contrast Ratio of the point X at Figure in Note (5).

Measurement System Setup:
The LCD module should be stabilized at given temperature for (20) minutes to avoid abrupt
temperature change during measuring. In order to stabilize the luminance, the measurement
should be executed after lighting Backlight for (20) minutes in a windless room.

2.6 Plug and Play

u The new VESA Plug and Play function is used which eliminates the complicated and

time-consuming installation process.

u You can use the Plug and Play system without encountering usual installation problems.

Your computer system can easily identify and automatically adjust the monitor.

u The LCD Monitor uses Display Data Channel (DDC) to send Extended Display

Identification Data (EDID) to the computer system, so the computer system can be set
to monitor auto adjust.

2.7 Power Saver

u Power control system, also called (Power Saver), is installed inside the LCD Monitor.
u If the monitor has not been used for a certain period of time, the system will turn the

monitor to low voltage mode to save power. Slight moving or any click will return to the
original image.

u The VGA card inside the computer handles Power Saver. You can use computer

software to set the function.

u The LCD Monitor is compatible with EPA ENERGY STAR and NÜ TEK if used with a

VESA DPMS computer.

u To save power, turn off the power of the LCD monitor when not in use.
