Using Yo ur Monitor

This chapter contains information about using your LCD monitor.

Turning the Monitor On and Off

Use the power button located at the lower middle of the front panel of the monitor to turn the
monitor on and off. When the monitor is on, the light (LED) near the Power button is illuminated.
The light is green when both the monitor and PC are active, and amber when the monitor is in a
reduced power mode.

If your PC sends power saving signals to the monitor, the monitor’s power management features
reduce power consumption to low levels when your PC goes into its power-saving mode. See the
“Minimizing Power Consumption” section for more information.

If your PC doesn’t use industry standard power-save signaling techniques, you can reduce power
consumption by turning off the monitor when it won ’t be used for an extended period. You can turn
the monitor off even if you leave your PC running.

Note:

Because of the technology used in LCD panels, screen savers will not prolong the life of
your monitor. So if t he monitor will not be used f or an extende d period, be su re to turn it off.

Wa rning

To completely disconnect power from your display, you must
remove the power cord from the wall outlet and then remove
the power cable from the display.

MAIN PAGE

Tilting the Monitor

The monitor has a tilt feature that allows you to tilt the monitor back and forth to find the most
comfortable viewing position. To tilt the monitor, grasp the sides and push the monitor back or pull
it toward you until it is in the desired position. The monitor can be tilted 20º backward and 5º
forward.

Note: Do not tilt the monitor by grasping the top edge.

Setting the Video Mode

Since the inherent format of this monitor is 1024 pixels by 768 lines, the monitor will perform best
when your PC is set to a screen resolution of 1024 x 768. If you use a lower resolution (such as 640
x 480), the image is expanded to fill the screen but with a slightly degraded image quality.

Your monitor supports many common video modes, as shown in the “Video Modes” section.
Check the documentation supplied with your PC and video adapter card to find out which modes
they support.

To view the video mode in Microsoft Windows, check the Windows settings in your PC.

Setting the Refresh Rate

The image refresh rate is the number of times per second that the image is refreshed; it is also
known as the vertical frequency.

Although your LCD monitor supports up to 75 Hz for analog video input, we recommend that you

9

MAIN PAGE

use 60 Hz refresh rate for best performance. The table in the “Video Mode” section shows the
image refresh rates supported by the monitor at different screen resolutions.

T o set the refresh rate with a standard Windows installation, consult your Windows or graphics card
documentation.

Minimizing Power Consumption

Many PCs support industry standard power-save signaling techniques. Power management
features reduce the monitor’s power consumption after a period of keyboard and mouse inactivity .

When the monitor is in a power-saving mode, the screen is blank and the power indicator turns
amber . P ressing a key on the keyboard or moving the mouse r estores the image in several seconds.
Consult your PC documentation for information about setting the power-saving modes.

The monitor accepts the signals for the three standard power-saving modes – Standby, Suspend,
and Sleep – from your PC. For any of these conditions, the monitor will go into Sleep mode.

Caring for and Cleaning the Monitor

To maximize screen life and prevent damage to the LCD panel, we recommend that you:

 Use the monitor power management system (if available on your PC).
 If you don’t use a power management system, t u rn off the monitor when you won’t be using it

for an extended period.

 Don’t press, rub, or poke the monitor with your finger or other object.
 Handle your monitor with care.

Your LCD module is a high-quality optical device that requires special care when cleaning.

Wa rning

Don’t use liquid, aerosol, or abrasive cleaning solutions to
clean the screen.

To clean the screen:

1. Shut down the PC.

2. Turn off and unplug the monitor.

3. Gently dust the screen with a dry, soft, lint-free cloth.

10

MAIN PAGE

Note: If the screen is still dirty, you can dampen the cloth with several drops of distilled water.

Make sure the LCD panel is completely dry before you turn the monitor back on.

4. Plug in the monitor.

5. Turn on your PC and monitor.

LCD Monitor Quality and Pixel Policy for
vf51 Monitor

vf51 15-inch monitor

The HP vf51 TFT monitor uses high-precision technology, manufactured according to HP
standards, to guarantee trouble-free performance. Nevertheless, the monitor may have cosmetic
imperfections that appear as small bright or dark spots. This is common to all LCD monitors used
in products supplied by all vendors and is not specific to the HP P4824A LCD. One or more
defective pixels or sub-pixels cause these imperfections.

• A pixel consists of one red, one green, and one blue sub-pixel.

• A defective whole pixel is always 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 P4824A monitor does not have more than:

• 10 total dot defects.

• 10 defective full pixels.

• 10 defective red sub-pixels.

• 4 defective green sub-pixels (green is most visible).

• 10 defective blue sub-pixels.

• No more than two adjacent (less than 2.5 mm edge-to-edge) and defective pixels.

• No more than two pairs of two adjacent defective pixels.

To locate defective pixels, the monitor should be viewed under normal operating conditions, in
normal operating mode at a supported resolution and refresh rate, from a distance of
approximately 50 cm (16 in.).

HP expects that, over time, the industry will continue to improve its ability to produce LCDs with
fewer cosmetic imperfections and HP will adjust guidelines as improvements are made.

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.

This product meets the requirements for the TCO'99 scheme which provides for an international
environmental and quality 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), Statens Energimyndighet
(The Swedish National Energy Administration) and SEMKO AB.

The requirements cover a wide range of issues: environment, ergonomics, usability, reduction of
electric and magnetic fields, energy consumption and electrical safety.

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 the environmenal labelling involve?

The environmental demands has been developed by Svenska Naturskyddsforeningen (The Swedish
Society for Nature Conservation). These 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.

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
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.

*

processes. Flame retardants have been found in human blood and researchers fear that

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. 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.

*

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

**

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