APPLECOLOR HIGH-RESOLUTION RGB MONITOR OWNER'S GUIDE
The AppleColor High-Resolution RGB Monitor is an ideal companion for your Macintosh
computer. Take a few minutes to review the information in this guide about setting up and
using your monitor.
About This Monitor and Guide
Your AppleColor High-Resolution RGB Monitor provides excellent image quality and an
ergonomic design. Some of its innovative features include:
- a Trinitron color picture tube for true colors and crisp, sharp focus
- a high-contrast, full-sized screen
- stable, flicker-free images
- high brightness for easy viewing
- easy-to-reach brightness and contrast controls
- manual degauss button to eliminate distortion and ensure maximum color purity
- height-adjustment bar to improve viewing angle
Your AppleColor High-Resolution RGB Monitor is easy to set up and adapt to your working
habits and environment. You can change the brightness and contrast of the monitor to suit
your preferences. You can also adjust the viewing angle of your monitor with the
accompanying height-adjustment bar or a monitor stand (available from your authorized
Apple dealer).
By the way: The name RGB means that the monitor creates color images by combining red,
green, and blue light.
Here's an overview of the topics you will find in this owner's guide:
- installing a video card, if needed
- setting up the optional monitor height-adjustment bar
- connecting the monitor to your Macintosh computer
- turning the monitor on
- setting the number of colors
- adjusting the monitor's display
- troubleshooting
You'll also find some tips on using and caring for the monitor, notes on service and
support, and a section that provides technical specifications.
Important Safety Guidelines
As you begin to set up your AppleColor High-Resolution RGB Monitor, keep in mind the
following:
- Read all the installation instructions carefully before you plug your monitor into an
electrical outlet.
- Keep these instructions handy for reference by you and others.
- Follow all instructions and warnings dealing with your system.
!! WARNING: Electrical equipment may be hazardous if misused. Operation of this
product, or similar products, must always be supervised by an adult. Do not allow
children access to the interior of any electrical product, and do not permit them to
handle any cables. !!
What You Need to Set Up Your Monitor
Before you set up the monitor, it's a good idea to have the original setup instructions
that came with your computer. In addition, you need these items, which are packaged with
your monitor:
- the height-adjustment bar
- the video cable
- the power cable
You may also need a video card (sometimes called a display card). A video card is not
required if your Macintosh model has a built-in video port (sometimes called on-board
video). However, you can add a video card that provides more capabilities than those of
the built-in video circuitry.
Your AppleColor High-Resolution RGB Monitor is designed to work with any of these three
video cards from Apple:
Macintosh Display Card Maximum number of colors
4•8 256
8•24 16.7 million
8•24 GC (accelerated) 16.7 million
Compatible video cards are also available from other manufacturers. Consult your
authorized Apple dealer for more information.
By the way: A video card is an example of what's called an "expansion" card because it
expands the capabilities of your computer.
If you're missing any of the pieces you need, contact your authorized Apple dealer.
Installing a Video Card
If you need to install a video card in one of the expansion slots inside your computer,
it's best to use the specific setup instructions that came with your computer. If you
don't have these, you can follow the general steps listed here. Don't worry if your
computer and video card look slightly different from the ones shown in Figure 1.
1. Make sure your computer's power cord is plugged into the recessed power plug on the
back of your computer and into a grounded electrical outlet or power strip.
2. If you hear the computer start up, turn it off using the button or switch on the back
panel.
3. Remove the lid from your computer.
4. To discharge any static electricity, touch the shiny metal cover of the power supply.
5. Choose any unused expansion slot.
If there is a protective metal shield for the slot inside the computer's back panel, lift
the shield up and out.
6. Push out the plastic cover for the slot so that there is an opening in the back panel
of the computer.
Figure 1 Adding a video card to a Macintosh IIfx computer
7. Remove the video card from its static-proof bag.
8. Hold the card by its top edge.
9. Align the video card connector over the expansion slot you want to use.
10. Press down firmly on the card until the connector is seated on the expansion slot.
11. Replace the lid on the computer.
After installing the video card, you'll see its video port accessible inside the opening
on the back of your computer. This is where you will connect the video cable.
Placing Your Monitor on Top of the Computer
Your AppleColor High-Resolution RGB Monitor is designed to fit right on top of the
computer case, but you can put it wherever you like -- for instance, next to the
computer. You also have the option to use the height-adjustment bar to raise the monitor
one-fourth or one-half inch higher.
Follow these instructions to use the height-adjustment bar:
1. Gently turn the monitor on its side.
2. Align the slots on the height-adjustment bar with the plastic guides on the bottom of
the monitor.
- To raise the monitor one-fourth inch, use the slots on the wide side of the bar.
- To raise the monitor one-half inch, use the slots on the narrow side of the bar.
3. Push the bar onto the plastic guides.
4. Gently return the monitor to its upright position.
Figure 2 Attaching the height-adjustment bar
If the height-adjustment bar doesn't meet your needs, you can purchase a monitor stand.
With a monitor stand, you can raise the monitor even higher and adjust the viewing angle.
Monitor stands swivel from side to side and tilt forward and back, allowing you to set
your monitor to the viewing angle you find most comfortable. (Monitor stands are
available from your authorized Apple dealer.)
!! WARNING: Protect your monitor from dampness and wet weather and keep it away from
other sources of liquids, such as coffee cups, drinking glasses, and wash basins. !!
Connecting Your Monitor
Before you connect the monitor to your computer, make sure your computer is turned off.
You need to attach the monitor's power and video cables to the back panel of your
computer. (Note the exception in step 3 for a Macintosh LC.) Follow these steps:
1. Place the monitor and computer so that you can easily get at the back panel of each.
2. Plug the socket end of the power cable (or, if you have a Macintosh LC, the extra
power cord that came with your computer) into the monitor's recessed power plug.
3. Plug the pronged end of the power cable into the computer's power socket (unless you
have a Macintosh LC).
- Most Macintosh models have a power socket on the back panel that matches the other end
of the monitor's power cable. The monitor's power cable will not fit into a wall outlet
or power strip.
- The Macintosh LC does not have a power socket for your monitor cable. You will need to
use the monitor power cord that came with your Macintosh LC to connect the monitor
directly to a grounded wall outlet or power strip.
By the way: If for some reason you decide not to plug your monitor into your computer,
or if you're using more than one monitor, you'll need at least two outlets near your
computer, and you'll need to contact your authorized Apple dealer to get a standard power
cord with a three-prong grounded plug.
4. Plug one end of the video cable (both ends are the same) into the monitor's video
socket.
The socket is on the monitor's back panel, marked with the video icon.
5. Tighten the thumbscrews.
Tightening the screws keeps the connection from coming loose and helps prevent radio and
television interference.
6. Connect the other end of the video cable to the appropriate video port on the
computer and tighten the thumbscrews.
- If you have not installed a video card, connect the cable to the built-in video port on
the computer's back panel.
- If you have installed a video card, connect the cable to the port on the video card.
TURNING YOUR MONITOR ON
To turn your monitor on, press the on/off button on the monitor's back panel. When you
turn on the monitor, you should see the green power-on light come on.
If it doesn't work: If the power-on light doesn't come on, press the on/off button
again. If this doesn't work, make sure you've connected the monitor according to the
instructions in "Connecting Your Monitor." For instance, if the monitor's power cable is
connected to your Macintosh, be sure the computer is turned on. If the light still
doesn't come on after you've checked the connections, consult "Troubleshooting."
To turn just the monitor off, you can press the monitor's on/off button. If you want to
turn off your entire computer system, leave the monitor's on/off button in the on
position, and shut down your computer. With the monitor plugged into the back of the
computer, shutting down the computer shuts down the whole system. The next time you turn
your computer on, the monitor will come on with it.
By the way: If you have a Macintosh LC or if you haven't connected the monitor's power
cable to your computer, you will need to turn the monitor on and off each time by using
the monitor's on/off button.
Setting the Number of Colors
You set the number of colors (or shades of gray) you want in the Monitors control panel,
according to the following steps. The boldface instructions for steps 2 through 5 are for
system software version 7.0 or later. Notes after those boldface steps explain any
differences with earlier versions of system software.
1. Start up your computer.
Depending on your model of Macintosh, you can press the Power On key on the keyboard or
use the on/off switch on the back of the computer. The Power On key does not work this
way with a Macintosh LC, so you need to use the on/off switch at the back of the
computer.
2. Choose Control Panels from the Apple menu.
If you are using a version of system software earlier than 7.0, you will need to choose
Control Panel from the Apple menu.
3. Open the Monitors control panel icon.
If you are using a version of system software earlier than 7.0, scroll in the small
window on the left side of the Control Panel to find the Monitors icon and then click the
icon.
4. Click Colors to turn on the color capability.)
5. Click the number of colors you wish to use.
See the Macintosh reference materials that came with your computer for more details on
using the Monitors control panel.

Adjusting the Display
You can adjust the screen display on the monitor to suit your preferences, using these
controls:
- The brightness and contrast controls work just like those controls on a television.
- The degauss button corrects any distortions that might appear in the colors displayed
on your monitor.
These controls are described in the next sections.
The Brightness and Contrast Controls
Under normal lighting conditions, you'll get the best results by setting the brightness
and contrast controls as follows:
1. Turn the contrast control clockwise as far as it will go.
This gives maximum contrast.
2. Turn the brightness control clockwise until it's in about the center, or detent,
position.
As you turn the brightness control, you'll feel a catch near the center of the brightness
range. This detent position marks the best balance between light and dark on your
monitor.
It takes about 20 minutes for the monitor to warm up completely. During this time you may
see slight changes in brightness.
For best performance over the life of the monitor, keep brightness set below maximum,
preferably at the detent position. You will find tips for adjusting brightness and
contrast to avoid eyestrain in various room lighting situations in "Troubleshooting."
The Degauss Button
Changes in the magnetic field around a monitor can cause distortions to the image
displayed on the screen. The magnetic field may change when you move the monitor, or when
you bring a magnetized object, such as an audio speaker, close to the monitor.
The monitor automatically adjusts, or degausses (de gous' ez), every time you turn it on.
However, if you leave the monitor turned on over long periods (more than three days),
it's a good idea to press the manual degauss button on the back of the monitor. This
ensures that you are getting the best quality image possible.
The degauss button is located just below the on/off button on the back panel.Pressing the
degauss button makes the screen flicker for a few seconds as the degauss circuitry
corrects the colors in your monitor. When the screen becomes steady again, the colors
should be correct. If you still detect color distortion, contact your authorized Apple
dealer.
Using and Caring for Your Monitor
This section includes important guidelines on caring for your monitor and suggestions on
how to use it efficiently.
For Your Safety
For your own safety and that of your equipment, immediately disconnect the power plug
from the electrical outlet (by pulling the plug, not the cord) when any of the following
conditions exists:
- The power cord or plug becomes frayed or otherwise damaged.
- You spill something onto the case.
- Your monitor is exposed to rain or any other excess moisture.
- Your monitor has been dropped and damaged, or the case has been otherwise damaged.
- You suspect that your monitor needs service or repair.
- You want to clean the case (use only the recommended cleaning procedure described later
in this guide).
Working Tips
Here are some tips you should keep in mind when using the AppleColor High-Resolution RGB
Monitor:
- To reduce glare, place the monitor so that the screen won't reflect bright light. Also,
avoid placing the monitor near a source of bright light, such as a window.
- Staring at anything for a long time can cause eyestrain. Make it a rule to focus on a
distant object occasionally to relax your eye muscles.
Things to Avoid
Follow these guidelines to avoid damaging your monitor:
- Avoid placing objects -- books, papers, magazines, clothing, and so on -- where they
will block the cooling vents.
- Avoid jostling or bumping the monitor. It has sensitive internal parts that can be
damaged by rough treatment.
- Avoid exposing the monitor to direct sunlight. Heat can damage the case and even the
electronic circuitry.
- Avoid setting cups, glasses, or anything containing liquids on or beside the monitor.
Spilling liquid into any electronic device can damage the circuitry.
By the way: Your monitor feels warm to the touch when it's on. This is normal. Like a
television set, the electronic circuitry and picture tube give off some heat.
About Screen Savers
Images left on the screen for long periods of time can become permanently imprinted on
the screen. This effect reduces the phosphor brightness of the monitor in the areas where
the images appear. A screen saver is a special kind of utility software that preserves
the screen when your Macintosh is not being used for long periods of time. A screen saver
protects your monitor from phosphor degradation by darkening the screen. (Turning the
brightness control down to dim the screen can protect the monitor's phosphor, too.)
It's not a good idea to turn the contrast all the way down for long periods of time, or
to use a screen saver that leaves your screen completely black. A black screen gives the
impression that the computer is off, and someone might move the computer or unplug it -either of which can cause data loss or damage to the hard disk.
The best screen savers keep the screen dark while monitoring a moving image -- for
example, fireworks or roving geometric shapes.
You can get information about screen savers from your authorized Apple dealer.
Protecting Your Monitor from Theft
The small rectangular opening next to the video socket on the back of the monitor is for
connecting a security lock. It lets you attach a narrow, flexible cable that you can use
to secure your monitor (and the rest of your Apple computer system) to prevent theft.
(See Figure 10.) Security locks are available from your authorized Apple dealer.
Cleaning Your Monitor
Follow these procedures whenever you need to clean your monitor:
1. Turn off the monitor by pressing the on/off button.
2. Disconnect the monitor power cable or cord from your computer's power socket (or from
the electrical outlet if you have a Macintosh LC).
Pull the plug, not the cable or cord.
3. Clean the cabinet with a damp (not wet), lint-free cloth.
Don't use aerosol sprays, alcohol, solvents, or abrasives that might damage the finish on
the case.
4. If the screen gets dirty, apply a household glass cleaner to a clean cloth or paper
towel and wipe the screen.
Don't spray glass cleaner directly onto the screen. It could run down inside the case and
damage electrical circuits.
Keep your monitor clean: An accumulation of dust on the screen can result in reduced
y
image quality.
Storing Your Mointor
When you're not going to use your monitor for an extended period, it's a good idea to put
it back in its original packaging and store it in a place where the temperature stays
between -40F and 116F (-40C and 47C). The packing material will protect the monitor
against jarring bumps and spilled liquids.
Working with More Than One monitor
To use more than one monitor with your Macintosh computer, you need to install a video
card for each additional monitor. (Your computer must have a NuBus expansion slot to
accommodate each additional video card.)
To control how your monitors will interact, use the Monitors control panel to adjust the
monitor settings to suit your needs. (If you're using a version of system software
version earlier than 7.0, use the Monitors section of the Control Panel.) See your
Macintosh reference materials for more details.
If you're using more than one monitor and you notice that the image on one or both of the
monitors is unstable, your monitors may be interfering with each other. To find out if
this is the problem, turn off one of the monitors. If the image on the other monitor
becomes stable, you know that the problem is interference, or "jitter."
The solution to a jitter problem is to place your monitors farther apart. (Moving them 16
inches apart should eliminate the jitter.) If you have a limited work space and you want
to keep your monitors together, try setting the monitors at an angle so that their
screens are together and their back panels are apart.
Troubleshooting
This section gives solutions to some common problems you might encounter while using your
AppleColor High-Resolution RGB Monitor. If you have a problem with your monitor that you
can't solve, contact an authorized Apple dealer, or call one of the phone numbers listed
in "Service and Support."
There's a very thin gray line across the screen, about one-third of the way up from the
bottom
Solution: This thin line is a normal part of the Trinitron color picture tube design. It
appears only on the screen.
There's no image on the screen
Solution: Make sure that your monitor's video cable is connected to the video port (or
video card connector) on the Macintosh, and that the Macintosh is running. Make sure the
monitor is plugged into the computer's power socket (or other electrical outlet) and that
the power-on light is on. Finally, check the brightness and contrast settings to make
sure they aren't turned all the way down.
There's flickering and distortion on the screen
Solution: First, press the degauss button on the back of the monitor. If that doesn't
correct the problem, check to make sure the monitor's video cable is connected firmly to
the computer. If it is, the flickering could be caused by interference from a nearby
power line or electrical device -- for example, a radio, a microwave oven, or another
computer. Try moving the electrical devices that might be causing interference, or move
our Macintosh and monitor. ("Working With More Than One Monitor" explains how to deal
with interference that is caused by another monitor.)
Something magnetic (for example, a stereo speaker) near the monitor has disturbed the
colors on the screen
Solution: Press the degauss button on the back of the monitor.
The monitor's power-on light doesn't come on
Solution: Check to see that all cords and cables are plugged in properly.
In a dim room, faint lines are visible along the outer perimeter of the screen
Solution: Turn down the brightness slightly.
After the initial 20-minute warm-up time, or after many hours of use, the screen image
appears dim
Solution: Turn up the brightness to suit your preference.
Over time, you feel eyestrain
Solution: Adjust the contrast to suit your preference. In a bright room, contrast is
usually best set at maximum; in a dim room, lower contrast is usually more comfortable.
Also, be sure to take occasional breaks to focus your eyes on a distant object.
