Introduction
Thank you for purchasing an LG color monitor. This monitor
supports OSD, DDC2B and Sound. It will give you high resolution
performance and operation in a variety of video operating modes. It is
compatible with standard PC type personal computers. The 15-inch
(13.8 inches viewable) flat Square Tube design is excellent for use in
a Windows or desktop publishing environment, where smaller screen
sizes result in images difficult to see easily. The anti-glare treatment is
easy on the eyes.
The microprocessor-based On Screen Display (OSD) controls allow
you to adjust a variety of image controls, automatically storing up to 37
different video modes, including 6 pre-set modes.
For greater user health and safety, this monitor complies with the
Swedish Nutek MPR II requirements for low radiation emissions.
For low cost of monitor operation, this monitor is certified as meeting
the EPA Energy Star Requirements, and utilizes the VESA Display
Power Management Signalling (DPMS) protocol.
Please review this manual completely before operating the monitor.

Important Precautions
This unit has been engineered and manufactured to assure your
personal safety, but improper use can result in potential electrical
shock or fire hazard. In order not to defeat the safeguards
incorporated in this monitor, observe the following basic rules for its
installation, use, and servicing. Also follow all warnings and
instructions marked directly on your monitor.
On safety
1. Use only the power cord supplied with the unit. In case you use
another power cord, make sure that it is certified by the applicable
standards (UL/CSA or VDE) if not being provided by the supplier.
2. Operate the monitor only from a power source indicated in the
specifications of this manual or listed on the monitor. If you are not
sure what type of power supply you have in your home, consult
with your dealer.
3. Overloaded AC outlets and extension cords are dangerous. So are
frayed power cords and broken plugs. They may result in a shock
or fire hazard. Call your service technician for replacement.
4. DO NOT OPEN THE MONITOR. There are no user serviceable
components inside. There are Dangerous High Voltages inside,
even when the power is OFF. Contact your dealer if the monitor is
not operating properly.
5. To avoid personal injury :
Do not place the monitor on a sloping shelf unless properly secured.
Use only a stand recommended by the manufacturer.
Do not try to roll a stand with small casters across thresholds or
deep pile carpets.
6. To prevent Fire or Hazards:
Always turn the monitor OFF if you leave the room for more than a
short period of time. Never leave the monitor ON when leaving the
house.
A3
Keep children from dropping or pushing objects into the
monitor's cabinet openings. Some internal parts carry hazardous
voltages.
Do not add accessories that have not been designed for this
monitor.
During a lightning storm or when the monitor is to be left
unattended for an extended period of time, unplug it from the wall
outlet.
Do not bring magnetic devices such as magnets or motors near
the picture tube.
On installation
1. Do not allow anything to rest upon or roll over the power cord, and
do not place the monitor where the power cord is subject to damage.
2. Do not use this monitor near water such as near a bathtub,
washbowl, kitchen sink, laundry tub, in a wet basement, or near a
swimming pool.
3. Monitors are provided with ventilation openings in the cabinet to
allow the release of heat generated during operation. If these
openings are blocked, built-up heat can cause failures which may
result in a fire hazard. Therefore, NEVER:
Block the bottom ventilation slots by placing the monitor on a
bed, sofa, rug, etc.
Place the monitor in a built-in enclosure unless proper ventilation
is provided.
Cover the openings with cloth or other material.
Place the monitor near or over a radiator or heat source.
On cleaning
Unplug the monitor before cleaning the face of the picture tube.
Use a slightly damp (not wet) cloth. Do not use an aerosol
directly on the picture tube because overspray may cause
electrical shock
.
On repacking.
Do not throw away the carton and packing materials. They make
an ideal container in which to transport the unit. When shipping
the unit to another location, repack it in its original material.
A4

Power Management System
This monitor incorporates new circuitry for lowering energy usage
during idle time, following the Display Power Management Signalling
(DPMS) guide lines of the Video Electronics Standards Association
(VESA), and is certified as exceeding the EPA's Energy Star program
for reduced power usage.
For the power savings feature to operate, the monitor must be used with
either a PC having power saving circuitry. The monitor has three power-
saving states, and the power saving operation is indicated by the power
indicator on the front panel.
When the power indicator is green, operation is normal. When the
power indicator is Amber, the monitor is in a power saving mode.
If the power indicator is Amber, press the power button to turn on the
monitor. If the power indicator is Amber and you wish to use the PC
again, move your mouse pointer or touch a keyboard button. When the
monitor is not in use, save energy by turning it off.

Video Memory Modes
This multi-synchronous auto-scanning monitor can automatically
detect and display several video modes falling within the monitor's
scanning range of 30-70kHz Horizontal and 50-120Hz Vertical. In the
PC area, this relates to a maximum flicker free usable resolution of
1280 x 1024 at a non-interlaced refresh rate of 60Hz Vertical.
For convenience, the monitor has a 37 mode memory, of which 6
modes come from the factory preset to popular video modes as
described below.

Modes 13-37 are empty and can accept new video data.
If the monitor detects one of the above signals from your computer's
video card, it will recall that mode and any stored image adjustments
you may have made before. If the monitor detects a new video mode
that had not been present before or is not one of the above listed
factory presets, it will store a new mode automatically in one of the
blank (empty) memory modes (in this example, mode 13). When you
now adjust the OSD controls to your preference, these image settings
will also be stored in mode 13. Whenever your video card or PC
switches to the mode that the monitor recognizes as mode 13, your
personal image settings will also be recalled.
A16
A note about the video memory modes:
There is a total of 37 video memory modes, generally more modes than
you will use at any one time. Of these 37 modes, 6 are permanent,
factory fixed modes that cannot be changed, and another 6 are set at the
factory, but may be overwritten to make more room. The remaining 25
modes are left blank (empty). If you use up the 25 blank modes and still
have more new video modes, the monitor will store information in the
other 6 soft preset modes for the new mode storage. If additional new
modes are encountered, the monitor will delete the lowest memory mode
and add the new mode.
If you use a video card that has a number of resolutions and frequencies
that do not correspond to any of the monitor video modes set at the
factory, here's what will happen:
1) As the monitor encounters new video data, if you adjust the image
control icons, the monitor will save the new information in the next
available empty mode (mode 13 if this is the first new data
encountered).
2) If you have used up modes 13-37 with 25 new video modes, and the
monitor encounters another mode (38th mode), it will store the new
data in mode 13 and the old data of mode 13 is deleted.
In addition, If the monitor encounters 39th new video data, the old
data of mode 14 is deleted and 39th data will replace the mode 14,
with above method, when this monitor encounters new mode, it can
update from mode 13 to mode 37 sequentially and continuously.

available with your own image settings recalled automatically.
A17
Microphone Operation
On the left side there is a MIC (Microphone) jack. By plugging a
microphone in here, it may reduce the long length of cable needed to
reach the PC's sound card. In order to use this MIC jack, you need to
use the cable (supplied) to plug into the rear of the monitor (MIC
OUT) and into the MIC input jack of your sound card (if available).
If you lost the supplied cable, consult with your dealer or buy a stereo
cable.
Audio Features
A major feature of this monitor is its built-in audio system. This
conveniently integrates a stereo audio amplifier and speakers without
taking up any more space. Because the monitor is designed like this,
you can easily upgrade to audio capable multimedia applications by
attaching your PC with sound card to the back of this monitor. It will
result in significantly less cabling and space requirements.
Audio Connections
Use the supplied cable to attach to the rear of the monitor (AUDIO IN)
and to the sound card in your PC (line out). The cable will carry both
left and right channel signals in one wire. Make sure when you use
the PC to turn up the volume of the sound card all the way.
A18
Low Radiation Compliance (MPR II)
This monitor meets one of the strictest guidelines available today for
low radiation emissions, offering the user extra shielding and an anti-
static screen coating. These guidelines, set forth by a government
agency in Sweden, limit the amount of emission allowed in the
Extremely Low Frequency (ELF) and Very Low Frequency (VLF)
electromagnetic range.
Self Diagnostics
This monitor can sense when there is a possible problem present,
and informs you of this condition by presenting you with a SELF
DIAGNOSTICS OSD. This OSD may pop up when it is On but no
signal is detected. In this case the message NO SIGNAL DETECTED
will be high lighted, alerting you to check the signal cable
connections.

C H E C K I N P U T S I G N A L
N O S I G N A L D E T E C T E D
DDC (Display Data Channel)
DDC is a communication channel over which the monitor
automatically informs the host system (PC) about its capabilities.This
monitor has DDC function; DDC2B carry out uni-directional
communication between the PC and the monitor. Under these
situations, the PC sends display data to the monitor but not
commands to control the monitor settings.
NOTE :
PC must support DDC functions to do this.
Some older computer systems are not compatible with the
DDC standard. If your monitor is displaying a monochrome
image or the wrong resolution, need to change with a DDC
compatible VGA card.
A19
Troubleshooting
Symptom: SELF DIAGNOSTICS message.
Possible causes:
The signal cable is not connected.
Symptom: OUT OF FREQUENCY message appears.
Possible causes:
The frequency of the sync input is outside the operating range of
the monitor.

service technician to perform the safety check described in the
