Unpacking
Before unpacking the monitor, prepare a suitable workspace for
your monitor and computer. You need a stable and clean surface
near a wall power outlet. Make sure that monitor has enough
space around it for sufficient airflow. Though the monitor uses
very little power, some ventilation is needed to ensure that the
monitor does not become too hot.
After you unpack the monitor box, make sure that the following
items were included in the box:
■ Monitor
■ 1.5M Monitor-to-PC VGA Cable
■ 2M Monitor-to-PC DVI-D Cable (digital models only)
■ 1.5M Stereo Jack Audio Cable (speaker models only)
■ 1.8M Power Cord

Troubleshooting
This monitor has been pre-adjusted using factory standard VGA
timings. Due to the output timing differences among various
VGA cards in the market, users may initially experience an
unstable or unclear display whenever a new display mode or new
VGA card is selected.
Note: This monitor supports multiple VGA modes. Refer to the
Preset Display Modes Table for a listing of modes supported by
this monitor.
PROBLEM: Picture is unclear and unstable.
The picture is unclear and unstable, please perform the following
steps :
1. Enter PC to "Shut Down Windows" status while you're in
MS-Windows environment.
2. Check the screen to see if there's any black vertical stripes
appear. If there are, take advantage of the "Clock" function
in OSD menu and adjust (by increment or decrement
numbers) until those bars disappear.
3. Move to "Phase" function in OSD menu again and adjust the
monitor screen to its most clear display.
4. Click "No" on "Shut Down Windows" and back to the
normal PC operating environment.
Compaq 7020 Flat Panel Monitor User’s Guide

Troubleshooting
PROBLEM: There is no picture on the monitor.
If there's no picture on the monitor, please perform the following
steps:
1. Make sure the power indicator on the monitor is ON, all
connections are secured, and the system is running on the
correct timing. Refer to Chapter 3 for information on
timing.
2. Turn off the monitor and then turn it back on again. If there
is still no picture, press the Adjustment Control button
several times.
3. If step 2 doesn't work, connect your PC system to another
external CRT. If your PC system Functions properly with a
CRT monitor but it does not function with the monitor, the
output timing of the VGA card may be out of the LCD's
synchronous range. Please change to an alternative mode
listed in the Standard Timing Table or replace the VGA card,
and then repeat steps 1 and 2.
PROBLEM: There is no picture on monitor.
If you have chosen an output timing that is outside of the
monitor's synchronous range (Horizontal: 30~ 80KHz and
Vertical: 56 ~ 75 Hz), the OSD will display an "Out of Range"
message. Choose a mode that is supported by your monitor.
Also, if the signal cable is not connected to monitor at all or
properly, the monitor screen will display a message "No Input
Signal".

TCO ‘99
Congratulations!
You have just purchased a TCO'99 approved and labelled
product! Your choice has provided you with a product developed
for professional use. Your purchase has also contributed to
reducing the burden on the environment and also to the further
development of environmentally adapted electronics products.
Why do we have environmentally labelled computers?
In many countries, environmental labelling has become an
established method for encouraging the adaptation of goods and
services to the environment. The main problem, as far as
computers and other electronics equipment are concerned, is that
environmentally harmful substances are used both in the
products and during their manufacture. Since it is not so far
possible to satisfactorily recycle the majority of electronics
equipment, most of these potentially damaging substances
sooner or later enter nature.
Compaq 7020 Flat Panel Monitor User’s Guide
B-1
TCO ‘99
There are also other characteristics of a computer, such as energy
consumption levels, that are important from the viewpoints of
both the work (internal) and natural (external) environments.
Since all methods of electricity generation have a negative effect
on the environment (e.g. acidic and climate-influencing
emissions, radioactive waste), it is vital to save energy.
Electronics equipment in offices is often left running
continuously and thereby consumes a lot of energy.
What does labelling involve?
This product meets the requirements for the TCO'99 scheme
which provides for international and environmental labelling of
personal computers. The labelling scheme was developed as a
joint effort by the TCO (The Swedish Confederation of
Professional Employees), Svenska Naturskyddsforeningen (The
Swedish Society for Nature Conservation) and Statens
Energimyndighet (The Swedish National Energy
Administration).
Approval requirements cover a wide range of issues:
environment, ergonomics, usability, emission of electric and
magnetic fields, energy consumption and electrical and fire
safety.
The environmental demands impose restrictions on the presence
and use of heavy metals, brominated and chlorinated flame
retardants, CFCs (freons) and chlorinated solvents, among other
things. The product must be prepared for recycling and the
manufacturer is obliged to have an environmental policy which
must be adhered to in each country where the company
implements its operational policy.
The energy requirements include a demand that the computer
and/or display, after a certain period of inactivity, shall reduce its
power consumption to a lower level in one or more stages. The
length of time to reactivate the computer shall be reasonable for
the user.
Labelled products must meet strict environmental demands, for
example, in respect of the reduction of electric and magnetic
fields, physical and visual ergonomics and good usability.

Environmental Requirements
Flame retardants
Flame retardants are present in printed circuit boards, cables,
wires, casings and housings. Their purpose is to prevent, or at
least to delay the spread of fire. Up to 30% of the plastic in a
computer casing can consist of flame retardant substances. Most
flame retardants contain bromine or chloride, and those flame
retardants are chemically related to another group of
environmental toxins, PCBs. Both the flame retardants
containing bromine or chloride and the PCBs are suspected of
giving rise to severe health effects, including reproductive
damage in fish-eating birds and mammals, due to the
bioaccumulative* processes. Flame retardants have been found
in human blood and researchers fear that disturbances in foetus
development may occur.
The relevant TCO'99 demand requires that plastic components
weighing more than 25 grams must not contain flame retardants
with organically bound bromine or chlorine. Flame retardants are
allowed in the printed circuit boards since no substitutes are
available.

Cadmium is present in rechargeable batteries and in the colour-
generating layers of certain computer displays. Cadmium
damages the nervous system and is toxic in high doses. The
relevant TCO'99 requirement states that batteries, the colour-
generating layers of display screens and the electrical or
electronics components must not contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays and switches. It
damages the nervous system and is toxic in high doses. The
relevant TCO'99 requirement states that batteries may not
contain any mercury. It also demands that mercury is not present
in any of the electrical or electronics components associated with
the labelled unit. There is however one exception. Mercury is,
for the time being, permitted in the back light system of flat
panel monitors as there today is no commercially available
alternative. TCO aims on removing this exception when a
mercury free alternative is available.
CFCs (Freons)
The relevant TCO'99 requirement states that neither CFCs nor
HCFCs may be used during the manufacture and assembly of the
product. CFCs (freons) are sometimes used for washing printed
circuit boards. CFCs break down ozone and thereby damage the
ozone layer in the stratosphere, causing increased reception on
earth of ultraviolet light with e.g. increased risks of skin cancer
(malignant melanoma) as a consequence.

Lead**
Lead can be found in picture tubes, display screens, solders and
capacitors. Lead damages the nervous system and in higher
doses, causes lead poisoning. The relevant TCO´99 requirement
permits the inclusion of lead since no replacement has yet been
developed.
*Bioaccumulative is defined as substances which accumulate
within living organisms.
**Lead, Cadmium and Mercury are heavy metals that are
Bioaccumulative.
