Important Safety Instructions

Minimizing Eye Strain

To avoid screen flicker and minimize eye strain, use the highest
supported image refresh rate for the chosen resolution. It is
recommended that you use a refresh rate of 85 Hz. The image refresh
rate is the number of times per second that the image is refreshed.

Minimizing Energy Consumption

If your computer supports VESA monitor power management
(available on many HP computers), you can minimize the power
consumed by the monitor. There is one power saving mode:
• Active off mode1 (uses less than or equal to 3W). In this mode, the
monitor's front panel indicator light is amber.
To set these power saving modes, refer to the manual that came with
your computer. If your screen is not displaying an image, check the
front panel indicator light first as your monitor may be in a power
saving mode.

1. Unique power saving mode which is activated if SYNC, H SYNC or V SYNC inactive.

Troubleshooting
Refer to this section, before contacting technical support.

If thin lines appear on your screen (damper wires)

The lines you are experiencing on your screen are normal for the
Trinitron monitor and are not a malfunction. These are shadows from
the damper wires used to stabilize the aperture grille and are most
noticeable when the screen’s background is light (usually white). The
aperture grille is the essential element that makes a Trinitron picture
tube unique by allowing more light to reach the screen, resulting in a
brighter, more detailed picture.

Damper wires

On-screen messages
If there is something wrong with the input signal, one of the following
messages appears on the screen.

If NO INPUT SIGNAL appears on the screen

This message shows the currently selected INPUT.

NO INPUT SIGNAL. This indicates that no signal is input

from the selected connector.

Troubleshooting

The Remedies
One or more of the following messages may appear on the
screen.
If ACTIVATE USING PC appears on the screen, try pressing
any key on the computer, and confirm that your computer’s
graphic board is completely seated in the correct bus slot.
If CHECK INPUT SELECTOR appears on the screen, try
changing the input signal.
If CHECK SIGNAL CABLE appears on the screen, check that
the monitor is correctly connected to the computer.

If OUT OF SCAN RANGE appears on the screen

This message shows the currently selected connector

(INPUT 1 or INPUT 2). If the monitor recognizes the
frequencies of the current input signal, the horizontal and
vertical frequencies are also displayed.

This indicates that the input signal is not supported by the

monitor’s specifications.

If you are replacing an old monitor with this monitor,

reconnect the old monitor. Then adjust the computer’s
graphics card so that the horizontal frequency is between 30 -
130 kHz, and the vertical frequency is between 48 - 170 Hz.

Care and Cleaning

Care and Cleaning

Do not place anything on top of the monitor. Doing so may block the
monitor vents and cause damage to the monitor due to overheating.
Do not let liquid get on or into the monitor. To maximize screen life
and prevent damage to the picture tube (such as burned phosphor
due to leaving the same image on the screen for a long time), it is
recommended that you:
• Use the monitor power management system (on HP computers) or
a screen saver program.
• Avoid setting contrast and brightness to their maximum levels for
prolonged periods.
• If you do not have a power management system or a screen saver
program, switch the monitor off or reduce the brightness and
contrast to minimum levels when the monitor is not in use.
Your monitor has an anti-glare, anti-static screen coating. To prevent
damage to the monitor screen's coating, use a regular household
glass cleaner when cleaning the screen. To clean the screen:
1 Switch the monitor off and remove the power plug (pull the plug,
not the cable).
2 Wet a soft cotton cloth with the cleaning solution and gently wipe
the screen. Do not spray cleaner onto the screen because the
cleaner may drip inside the monitor.
3 Dry with a clean, soft cotton cloth. Do not use any type of abrasive
pad, alkaline cleaner, scouring powder or solvents such as alcohol
or benzine as they might damage the anti-reflective coating.

Environmental Information
HP has a strong commitment toward the environment. Your HP
monitor has been designed to respect the environment as much as
possible.
HP can also take back your old monitor for recycling when it reaches
the end of its useful life. In fact, HP has a product take-back program
in several countries. The collected equipment is sent to one of HP's
recycling facilities in Europe or the USA. As many parts as possible
are reused. The remainder is recycled. Special care is taken for
batteries and other potentially toxic substances, which are reduced
to non-harmful components through a special chemical process. If
you require more details about HP's product take-back program,
contact your dealer or your nearest HP Sales Office.

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.
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.

Regulatory Information

Below you will find a brief summary of the environmental requirements met by this
product. The complete environmental criteria document may be ordered from:
TCO Development
SE-114 94 Stockholm, Sweden
Fax: +46 8 782 92 07
Email (Internet): development@tco.se
Current information regarding TCO'99 approved and labelled products may also be
obtained via the Internet, using the address: http://www.tco-info.com/
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 bio-accumulative1 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.
Cadmium2
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.
Mercury2
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.
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.
Lead2
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.

1. Bio-accumulative is defined as substances which accumulate within living organisms

2. Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
