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.

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.

Self Diagnostics
The Studioworks 99T has a SELF DIAGNOSTICS OSD feature that
pops up when there may be possible causes of non-operation. The
OSD would highlight a possible reason the display is not showing an
image. An example of this may be when you turn on the monitor with
no signal cable attached. The monitor will display the SELF
DIAGNOSTICS OSD with the CHECK INPUT SIGNAL. This would be
a clue for you to check the signal 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 three DDC function; DDC1, DDC2B.
DDC1 and 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.
If you using the 5 BNC connector with other types of video
cards, this monitor has not support DDC function.
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
antistatic 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.

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 30-96kHz Horizontal and 50-160Hz Vertical. In the
PC area, this relates to a maximum flicker-free usable resolution of
1600x1200 at a non-interlaced refresh rate of 75Hz Vertical.
For convenience, the monitor has a 40 mode memory, of which 12
modes come from the factory preset to popular video modes as
described below.
Modes 25-40 are empty and can accept new video data.
If the monitor detects one of the signals above 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 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 25). When you now
adjust the digital controls to your preference, these image settings will
also be stored in mode 25. Whenever your video card or PC switches
to the mode that the monitor recognizes as mode 25, your personal
image settings will also be recalled.

Polarity

A note about the video memory modes:
There is a total of 40 video memory modes, generally more modes than
you will use at any one time. Of these 40 modes, 12 are permanent,
factory fixed modes that cannot be changed, and another 12 are set at
the factory, but may be overwritten to make more room. The remaining
16 modes are left blank (empty). If you use up the 16 blank modes and
still have more new video modes, the monitor will store information in the
other 12 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 25 if this is the first new data
encountered).
2) If you have used up modes 25-40 with 16 new video modes, and the
monitor encounters another mode (41th mode), it will store the new
data in mode 25 and the old data of mode 25 is deleted.
In addition, If the monitor encounters 42th new video data, the old
data of mode 26 is deleted and 42th data will replace the mode 26,
with above method, when this monitor encounters new mode, it can
update from mode 25 to mode 40 sequentially and continuously.
Because the monitor is designed this way, you will always have the
most recent 28 video modes generated by your graphics card
available with your own image settings recalled automatically.
