OMPAQ 1024 COLOR MONITOR
This manual provides information necessary for you to install and
operate the COMPAQ 1024 Color Monitor.
A
BOUT THE MONITOR
The 1024 Color Monitor is a microprocessor based, intelligent scanning
color monitor. It is best suited for applications from word processing to
spreadsheets to CAD/CAE. Its microprocessor intelligence allows easy
adjustment of screen configurations with various display modes.
Some of the features of the 1024 Color Monitor are as follows:
•Supports VGA standards, Super VGA (800 x 600), 8514/A
(1024 x 768 interlaced), and 1024 x 768 non-interlaced mode.
•Analog input allows the monitor to display up to 256 colors.
•Front panel controls to adjust the Horizontal-size, Horizontal-
position, Vertical-size, and Vertical-position in each display mode.
•Built-in automatic frequency control that eliminates the need of
Horizontal-hold controls.
•Automatically scans the horizontal frequency from 30 to 58 KHz
and the vertical frequency from 50 to 100 Hz.
•Monitors compliant with MPR 1990 Emissions Standards are
identified by a statement on the product label.
I
NSTALLING THE MONITOR
All COMPAQ personal computers have integrated display adapters that
work with the 1024 Color Monitor. If your computer requires a
separate display adapter, install it before proceeding with these
instructions.

COMPAQ 1024 Color Monitor 2
To install the monitor, ensure that power to the monitor, computer
system, and other attached devices is off and complete the following
steps:
1. Connect the monitor AC power cord to a properly grounded AC
outlet that is easily accessible and located as near the monitor as
possible. Depending on your location, the power cord for your
monitor could be different from the one in the illustration.
2. Connect the video cable on the monitor to the 15-pin video
graphics connector and tighten the fastening screws.
IMPORTANT: Make sure the signal cable aligns with the video
graphics connector. Do not force the cable onto the connector, or you
may damage the video cable.
Rear Panel Connectors
WARNING: This equipment is designed for connection
to a grounded (earthed) outlet. The 3-prong grounding
type plug is an important safety feature. To avoid risk of
electric shock or damage to your equipment, do not
disable this feature.

ARE AND MAINTENANCE
•Use only a power source and connection appropriate for this
monitor, as indicated on the marking label/back plate.
•When you connect the monitor to an outlet or extension cord, make
sure the total ampere rating of the products connected to the outlet
does not exceed the current rating of the electrical outlet, and the
total ampere rating of the products connected to the cord do not
exceed the rating of the cord.
•Install the monitor near an outlet that you can reach easily.
Disconnect the product by grasping the plug firmly and pulling it
from the outlet. Never disconnect it by pulling the cord.
•Unplug the monitor from the wall outlet before cleaning. Do not
use liquid cleaners or aerosol cleaners. Use a damp cloth for
cleaning.
•Do not drop the monitor or place it on an unstable surface.
•Slots and openings in the cabinet are provided for ventilation; these
openings must not be blocked or covered. Never push objects of
any kind into cabinet slots or other openings.
•Do not allow anything to rest on the power cord. Do not walk on
the cord.
•Keep the monitor in a well-ventilated area, away from excessive
light, heat and moisture. Keep the monitor away from high capacity
transformers, electric motors, and other strong magnetic fields.
•Do not open the monitor cabinet or attempt to service this product
yourself. Adjust only those controls that are covered by the
operating instructions. If the monitor is not operating properly, or
has been dropped or damaged, contact your dealer.

DVANCED PICTURE ADJUSTMENTS
This section is intended for the experienced user only. It includes a brief
description on adjusting the picture geometry, as well as the vertical
and horizontal position and size.
NOTE: Specific test patterns and service experience may be required
to perform these adjustments. If you have any problems adjusting the
service controls, just press Reset and start again.

hanging Front Panel Control Functions
A set of DIP switches recessed on the front panel of the 1024 Color
Monitor changes the functions of the front panel control buttons. Once
set, the settings are automatically saved and recalled each time you
change the monitor's mode
Both the DIP switches are set to Off at the factory, and you can use the
front panel controls control the following user functions:

Appendix A-3
The function of each control may be described as follows:
1. Vertical linearity
If a cross-hatch pattern is displayed on the screen, equal spacing
between the horizontal bars at the top and bottom of the screen
indicates good linearity. However, if the horizontal bars appear to
be crowded at the top of the bottom, the vertical linearity controls
can be used to correct the problem.
2. Vertical S-correction
For a cross-hatch pattern displayed on the screen, if the horizontal
bars appear to be crowded near the center but are of equal spacing
at the top and bottom, the vertical S-correction controls can be
used to correct the problem.
3. Vertical/horizontal compensation
Together with the Horizontal compensation controls, these controls
minimizes the "breathing" effect when the Brightness control is
turned up or down with the Contrast control set at maximum.
4. East-west corner / east-west parabola
Together with the East-west parabola controls, these controls can
be used to correct pincushion and barrel distortions.
5. Trapezium correction
Minimize the trapezium distortion of the display screen.
6. Horizontal frequency hold
For input Horizontal-frequencies that are different from the preset
timings, these controls may be used to synchronize the monitor with
the input signal.
D
IP Switch Defaults
The monitor always powers on with the front panel controls controlling
the user functions regardless of the actual DIP switch settings. If the
monitor is powered on with the DIP switch setting other than the
default, reset the DIP switches to their default settings (Off) first before
setting them again to change the front panel control functions.
