Introduction
Thank you for purchasing an LG high resolution monitor. It will give
you high resolution performance and convenient reliable operation in a
variety of video operating modes.
Features
The 99T is a 19-inch (18.0 inches viewable ) intelligent, microproces-
sor based monitor compatible with most analog RGB (Red, Green,
Blue) display standards, including IBM PC®, PS/2®, Apple®,
Macintosh®, Centris®, Quadra®, and Macintosh II family. It can also be
used with a Sun SPARC workstation as well as other sources using
the 5 BNC connectors. The monitor provides crisp text and vivid color
graphics with VGA, SVGA, XGA, and VESA Ergo modes (non-
interlaced), and most Macintosh compatible color video cards when
used with the appropriate adapter.
The monitor's wide compatibility makes it possible to upgrade video
cards or software without purchasing a new monitor.
Digitally controlled auto-scanning is done with the microprocessor for
horizontal scan frequencies between 30 and 96kHz, and vertical scan
frequencies between 50 and 160Hz. 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 conveniently
adjust a variety of image controls by using the OSD (On Screen
Display).
The monitor is shipped with 12 factory pre-programmed video modes
that are permanently resident, and another 12 are set at the factory,
but may be overwritten to make more room. In addition, there are 16
user storable modes, for a total of 40 memory modes.
This monitor is capable of producing a maximum horizontal resolution
of 1600 dots and a maximum vertical resolution of 1200 lines. It is well
suited for CAD work and sophisticated windowing environments.
For greater user health and safety, this monitor complies with the
stringent Swedish TCO’95 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 for power saving
during non-use periods.

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
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.
3
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.

Connecting the Monitor
On the back of the monitor are three plug-in connections; one for the
AC power cord, and the others for the signal cable from the video card.
1. AC Power Connection
One end of the AC power cord is connected into the AC power connector
on the back of the monitor. The other end is plugged into a properly
grounded three-prong AC outlet. The monitor's auto-sensing power supply
can automatically detect 100-120V AC or 200-240V AC, 50 or 60Hz.
2. Signal Cable Connection
The connectors for the signal cable are located on the back of the
monitor. The BNC and 15 pin VGA connectors on the back of the
monitor allow for a wide variety of video controllers to be connected to
the monitor. Examples of signals that might be sent to the monitor
include signals from IBM PC and compatibles, Apple Macintosh,
Centris, Quadra, and SPARC workstations.
The supplied signal cable consists of 15 pin VGA connectors at both
ends, suitable for connections to an IBM PC or compatible.
Other generic cables or adapters may be used for connections to your
equipment, as long as they meet the compatible signal requirements
to activate this monitor (see page 24 for input specifications). For
Apple Macintosh use, a separate plug adapter is needed to change
the 15 pin high density (3 row) D-sub VGA connector on the supplied
cable to a 15 pin 2 row connector. Examples of typical connections
are shown below. Select the connection example that fits your needs.

A) Connection to any IBM VGA PC compatible system
Figure 3 shows the signal cable connections from the monitor to the
Video Graphics Array (VGA) port typical in an IBM PC or PC
compatible. This also applies to any graphics video card for PC-CAD
or workstation that has a 15 pin high density (3 row) D-Sub connector.
1.Power off both the monitor and PC.
2.Connect the 15 pin VGA connector of the supplied signal cable to
the output VGA video connector on the PC and the matching input
connector on the rear of the monitor. The connectors will mate
only one way. If you cannot attach the cable easily, turn the
connector upside down and try again. When mated, tighten the
thumbscrews to secure the connection.
3.Power ON the PC, then the monitor.
4.If you see the SELF DIAGNOSTICS message, check the signal
cable and connectors.
5.After using the system, power OFF the monitor, then the PC.

B) Connecting to an Apple Macintosh II, Centris, and Quadra
Figure 4 shows the connection to an Apple Macintosh, using a
separately purchased adapter.
1.Power OFF both the monitor and the PC.
2.Connect the 15 pin VGA connector of the supplied signal cable to
the matching input on the back of the monitor. Tighten the
thumbscrews to secure the connection.
3.Locate the appropriate MAC to VGA adapter block at your local
computer store. This adapter changes the high density 3 row 15
pin VGA connector to the correct 15 pin 2 row connection to mate
with your MAC. Attach the other end of the signal cable to the
side of the adapter block with 3 rows.
4.Connect the attached adapter block/signal cable to the video
output on your MAC.
5.Power ON the PC, then the monitor.
6.If you see the SELF DIAGNOSTICS message, check the signal
cable and connectors.
7.After using the system, power OFF the monitor, then the PC.
