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  
 
Installing the Tilt/Swivel Base  
Turn off the equipment and all attached options.  
Carefully set the monitor face-down with the underside facing you.  
Installation  
1.Align the hooks on the tilt/swivel stand with the matching slot on the  
base (underside of the monitor). The open hooks of the stand  
should face the front of the monitor. The matching slots are on the  
first row of slots showing 2 pairs of slots.  
2.Insert the hooks into the front and rear slots. The stand should now  
fit flush with the bottom of the monitor.  
3.Slide the stand toward the front of the monitor, until the latch clicks  
into the locked position. Now only the bottom of the stand should be  
movable.  
4.Carefully upright the monitor, taking care to place the monitor down  
flatly on an even surface.  
NOTE: To remove the stand, gently push in the latch on the bottom of  
the monitor and then slide the stand toward the back of the monitor.  
After sliding the stand back, lift off the stand from the monitor.  
A5  
 
Installation  
The supply voltage is marked on the ID label located on the rear  
panel of the monitor. If your local voltage is different, do not use the  
monitor and contact your supplier before using the display.  
Connections  
To connect your monitor after the video adapter is properly installed:  
1. Turn OFF the power to your computer and all its attached options.  
2. Position the monitor and the computer so that you can easily  
get to the back panel of each.  
3. Connect the signal cable with D-sub connector to the graphics  
board on your PC as described in your PC Owner's Manual.  
4. Tighten the screws on the video cable connectors to keep them  
from coming loose and to prevent radio and TV interference.  
5. Connect the power cord to the AC receptacle on the back of the  
monitor. Plug the other end of the power cord into a properly  
grounded electrical outlet.  
6. The socket-outlet should be installed near the equipment and

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.

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.

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.

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.

qualified technician to restore the monitor to normal operation.  
The monitor has been dropped or the cabinet has been  
damaged.  
The monitor exhibits a distinct change in performance.  
Snapping or popping from the monitor is continuous or frequent  
while the monitor is operating. It is normal for some monitors to  
make occasional sounds when being turned on or off, or when  
changing video modes.  
2. Do not attempt to service the monitor yourself, as opening or  
removing covers may expose you to dangerous voltage or other  
hazards. Refer all servicing to qualified service personnel.  
3. When replacement parts are required, have the service technician  
verify in writing that the replacements used have the same safety  
characteristics as the original parts. Use of manufacturer specified  
replacements can prevent fire, shock, and other hazards.
