Introduction

Thank you for purchasing an GoldStar high resolution monitor. It will

give you high resolution performance and convenient reliable

operation in a variety of video operating modes.

Features

The StudioWorks 77i is a 17-inch (15.9 inches viewable ) intelligent,

microprocessor 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. 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 adaptor.

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 70KHz, 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 adjust

conveniently 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 25

user storable modes, for a total of 49 memory modes.

This monitor is capable of producing a maximum horizontal resolution

of 1280 dots and a maximum vertical resolution of 1024 lines. It is

well suited for CAD work and sophisticated windowing environments.

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.

WARNING : To reduce the risk of fire or electric shock, do not

expose this appliance to rain or moisture.

AVERTISSEMENT :

Ne pas placer cet appareil dans un endroit humide.

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 :

@@@@@@@@@@@@g

Do not place the monitor on a sloping shelf unless properly secured.

@@@@@@@@@@@@g

Use only a stand recommended by the manufacturer.

@@@@@@@@@@@@g

Do not try to roll a stand with small casters across thresholds or

deep pile carpets.

6. To prevent Fire or Hazards:

@@@@@@@@@@@@g

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.

@@@@@@@@@@@@g

Keep children from dropping or pushing objects into the

monitor's cabinet openings. Some internal parts carry hazardous

voltages.

@@@@@@@@@@@@g

Do not add accessories that have not been designed for this

monitor.

@@@@@@@@@@@@g

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.

@@@@@@@@@@@@g

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:

@@@@@@@@@@@@g

Block the bottom ventilation slots by placing the monitor on a

bed, sofa, rug, etc.

@@@@@@@@@@@@g

Place the monitor in a built-in enclosure unless proper ventilation

is provided.

@@@@@@@@@@@@g

Cover the openings with cloth or other material.

@@@@@@@@@@@@g

Place the monitor near or over a radiator or heat source.

On Cleaning

@@@@@@@@@@@@g

Unplug the monitor before cleaning the face of the picture tube.

@@@@@@@@@@@@g

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.

@@@@@@@@@@@@g

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 two 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 connector for the signal cable is located on the back of the

monitor. The 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 and

Quadra.

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 22 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.

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 NO SIGNAL message, check the signal cable and

connectors.

5.After using the system, power OFF the monitor, then the PC.

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.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.

3.Connect the attached adapter block/signal cable to the video

output on your MAC.

4.Power ON the PC, then the monitor.

5.If you see the NO SIGNAL message, check the signal cable and

connectors.

6.After using the system, power OFF the monitor, then the PC.
