Introduction
The LG 500LC Flat Panel Monitor has an active matrix TFT (Thin-Film
Transistor) LCD (Liquid Crystal Display).
This monitor is designed for use in small working areas or for those who need
more working space on the desk.
Features
The 500LC is a 15.1-inch (15.1 inches viewable) intelligent micropro-cessor
based monitor.
Digitally controlled auto-scanning is done with the microprocessor for horizontal
scan frequencies between 31 and 61kHz, and vertical scan frequencies between
56 and 75Hz. The microprocessor-based intelligence allows the monitor to
operate in each frequency mode with the precision of a fixed frequency monitor.
The microprocessor-based digital controls allow you to adjust conveniently a
variety of image controls by using the OSD (On Screen Display).
It supports resolutions up to 1024x768, and has a wide viewing angle of 60
degrees horizontal and 45 degrees vertical.
The monitor is shipped with 14 factory pre-programmed video modes that are
permanently resident. In addition, there are 4 user-storable modes, for a total of
18 memory modes.
For greater user health and safety, this monitor complies with the stringent
Swedish TCO '95 requirements for low radiation emissions.

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. Power cord must meet the requirements of the
country where you use the monitor. For more information on power cord
requirements, contact your LG authorized dealer, reseller, or service provider.
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 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 or office.
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.

A4
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.
4. Do not rub or strike the Active Matrix LCD with anything hard as this may scratch,
mar, or damage the Active Matrix LCD permanently.
5. Do not press the LCD screen with your finger for a long time as this may incur
some afterimages.
6. Some dot defects may appear on the screen, like Red, Green or Blue spots on the
screen. However, this will have no impact or effect on the monitor performance.
7. If possible, use the VESA 1024x768 @60Hz video mode to obtain the best image
quality for your LCD monitor. If used under any modes except the VESA
1024x768 @60Hz video mode, some scaled or processed images may appear
on the screen. However, this is the characteristics of the LCD panel which has a
fixed resolution of 1024x768 at 60Hz.
On Cleaning
Unplug the monitor before cleaning the face of the LCD Screen.
Dust the monitor by wiping the screen and the cabinet with a soft, clean cloth. If
the screen requires additional cleaning, use a clean, damp cloth.
Do not use liquid cleaners or aerosol cleaners.
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.

A15
User Modes
Modes 15-18 are empty and can accept new video data. If the monitor detects a
new video mode that has not been present before or is not one of the preset
modes, it stores the new mode automatically in one of the empty modes starting
with mode 15.
If you use the 4 blank modes and still have more new video modes, the monitor
replaces the information in the user modes starting with mode 15.
Recalling Display Modes
When your monitor detects a mode it has seen before, it automatically recalls the
image settings you may have made the last time you used that mode.
You may, however, manually force a recall of each of the 14 preset modes by
pressing the Recall button. All preset modes are automatically recalled as the
monitor senses the incoming signal.
The ability to recall the preset modes is dependent on the signal coming from
your PC’s video card or system. If this signal does not match any of the factory
modes, the monitor automatically sets itself to display the image.

A16
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 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.
