Recognizing Preset Display Resolutions
The HP f2304 High Definition 23” LCD Monitor supports the
display resolution modes listed in the table below. Some of
these modes may not be available from the video graphics
system used in the computer. Preset modes 20, 22 and 24
supports the f2304 monitor using only the VGA signal input.
If using a DVI signal input, these preset modes will not
properly display although the operating system and video
graphics card may indicate these modes are supported.
Using modes 20, 22 and 24 with a DVI signal may not
display images properly on the screen. If changing
resolution modes does not display images properly, do not
touch your keyboard and 15 seconds later your settings will
revert to the previous resolution mode.
Preset mode 23, 1920 x 1200, is a new video resolution
mode developed for digital monitors that support DVI signal
input using reduced blanking techniques. Before selecting
this new video mode on the f2304 monitor and to avoid
images not displaying properly, refer to the documentation
that comes with the video graphics system to confirm if the
system supports this 1920 x 1200 reduced blanking mode.
If your digital graphics card provides the 1920 x 1200
digital resolution using a single DVI connector, then the
reduced blanking mode is supported.

LCD Monitor Quality and Pixel Policy
for f2304 Monitor
The HP f2304 monitor uses high-precision technology
manufactured according to HP standards, to guarantee
trouble-free performance. Nevertheless, the display may
have cosmetic imperfections that appear as small bright or
dark spots. This is common to all LCD displays used in
products supplied by all vendors and is not specific to the
HP f2304 displays. These imperfections are caused by one
or more defective pixels or sub-pixels.
■ A pixel consists of one red, one green, and one blue
sub-pixel.
■ A defective whole pixel is always turned on (a bright
spot on a dark background), or it is always off (a dark
spot on a bright background). The first is the more visible
of the two.
■ A defective sub-pixel (dot defect) is less visible than a
defective whole pixel and is small and only visible on a
specific background.
The HP display does not have more than:
■ 5 total defects — combination of full pixel and sub-pixel
defects
■ 3 defective bright sub-pixels
■ 5 defective dark sub-pixels
■ Bright dots must have a 15 mm minimum separation
■ Bright dot to dim dot must have a 5 mm minimum
separation
■ Dim dot to dim dot must have 5 mm minimum separation

Specifications
To locate defective pixels, the monitor should be viewed
under normal operating conditions and in normal operating
mode at a supported resolution and refresh rate, from a
distance of approximately 16 inches (50 cm).
HP expects that, over time, the industry will continue to
improve its ability to produce displays with fewer cosmetic
imperfections and HP will adjust guidelines as improvements
are made.
Entering User Modes
The video controller signal may occasionally call for a mode
that is not preset if:
■ You are not using a Hewlett-Packard standard graphics
adapter.
■ You are not using a preset mode.
If this occurs, you may need to readjust the parameters of the
monitor screen by using the on-screen display. Your changes
can be made to any or all of these modes and saved in
memory. The monitor automatically stores the new setting,
then recognizes the new mode just as it does a preset mode.
In addition to the 24 factory preset modes, there are four
user modes that can be entered and stored.

Using the Energy Saver Feature
When the monitor is in its normal operating mode, the
monitor uses less than 100 watts of power and the Power
light is green.
The monitor also supports a reduced power state. The
reduced power state will be entered into if the monitor
detects the absence of either the horizontal sync signal
and/or the vertical sync signal. Upon detecting the absence
of these signals, the monitor screen is blanked, the backlight
is turned off, and the Power light is turned amber. When the
monitor is in the reduced power state, the monitor will utilize
less than 3 watts of power. There is a brief warm-up period
before the monitor will return to its normal operating mode.
Refer to your computer manual for instructions on setting
energy saver features (sometimes called power management
features).
The above energy saver feature only works when connected
to computers that have energy saver features.
✎
By selecting settings in the monitor’s Energy Saver utility, you
can also program the monitor to enter into the reduced
power state at a predetermined time. When the monitor’s
Energy Saver utility causes the monitor to enter the reduced
power state, the Power light blinks amber.

TCO ‘99 Requirements
You have just purchased a TCO ‘99 approved and labeled
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 to the further
development of environmentally adapted electronics products.
Why do we have environmentally labeled computers?
In many countries/regions, environmental labeling 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 (for example, 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.

TCO ‘99 Requirements
What does the environmental labeling involve?
This product meets the requirements for the TCO ‘99 scheme which
provides for an international and environmental labeling of
personal computers. The labeling scheme was developed as a
joint effort by the TCO (The Swedish Confederation of Professional
Employees), Svenska Naturskyddsforeningen (The Swedish Society
for Nature Conservation), Statens Energimyndighet (The Swedish
National Energy Administration), and SEMKO AB.
The requirements cover a wide range of issues: environmental,
ergonomic, usability, reduction of electric and magnetic fields,
energy consumption, and electrical 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/region where the company
implements its operational policy.
The energy requirements include a demand that the computer
and/or monitor, 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.
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 ‘99 Requirements
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-accumulative processes.
Flame retardants have been found in human blood and
researchers fear that disturbances in fetus 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
color-generating layers of display screens and the electrical or
electronics components must not contain any cadmium.
*
Bio-accumulative is defined as substances which accumulate within living
organisms. Lead, Cadmium and Mercury are heavy metals which are
bio-accumulative.

TCO ‘99 Requirements
*
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
labeled 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):
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.
*
Bio-accumulative is defined as substances which accumulate within living
organisms. Lead, Cadmium and Mercury are heavy metals which are
bio-accumulative.
