WARNING
Working in
Comfort
CAUTION
For your safety always connect equipment to a grounded wall outlet.
Always use a power cord with a properly grounded plug, such as the one
provided with the equipment, or one in compliance with your national
safety standards. This equipment can be disconnected from the power
by removing the power cord from the power outlet. This means the
equipment must be located close to an easily accessible power outlet.
To avoid electrical shock, do not open the monitor's cover. There are no
user-serviceable parts inside. Only qualified service personnel should
service these parts.
Make sure your computer is powered off before connecting or

Setting the Amount of Displayed Information
Setting the Amount of Displayed Information
It is recommended that you use a resolution of 1280 x 1024 at
85 Hz. This gives easy-to-read characters, a large amount of displayed
information and a flicker-free image.
You can make adjustments to the displayed image which are
automatically saved for the resolution you are using. For example, if you
adjust your monitor when working in SVGA, those settings are saved for
SVGA. If you then work in VGA and change the image settings, they are
saved for VGA. The next time you switch back to SVGA your previous
settings are used automatically.
To find out which resolutions are supported by your monitor, refer to
“What Video Modes are Supported” on page 9. To change the screen
resolution, please refer to the manual that came with your computer or
your operating system documentation.
Your monitor has a Plug and Play capability (VESA DDC1/2B standard)
which enables it to identify itself to suitably equipped HP computers.
This will automatically give you the best refresh rate for the resolution
that you have set. Also, by using the appropriate software (when
available) you can adjust the monitor settings directly from your
computer.

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:

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.

Below you will find a brief summary of the environmental requirements met by this
product. The complete environmental criteria document may be ordered from:

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
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
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.
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.
