14  
User’s Guide  
   
2025 Flat Panel Display  
Entering sleep mode—Indicates the screen display is entering  
a sleep mode.  
No video input—Indicates the video cable may not  
be plugged into the computer or the computer may not be  
turned on.  
Adjusting Screen Quality  
Allow the monitor to warm up for 20 minutes before performing  
the following procedures.  
The Auto Adjustment feature automatically fine-tunes the image  
quality each time a new video mode is utilized. If additional  
improvement is desired, select the Auto Adjust control on the  
front bezel.  
For more precise adjustments, use the adjustment pattern  
provided on the CD-ROM, and adjust the clock and phase  
settings (accessed via the OSD) as described in the following  
section.  
Optimizing Digital Conversion  
This monitor contains advanced circuitry that allows the flat  
panel screen to function like a standard monitor. Two controls  
in the on-screen display can be adjusted to improve image  
performance: Clock and Clock Phase. Use these controls only  
when the auto adjust function does not provide a satisfactory  
image.  
Clock—Increase/decrease the value to minimize any vertical  
bars or stripes visible on the screen background.  
Clock Phase—Increase/decrease the value to minimize video  
distortion or video jitter.  
User’s Guide  
15  
   
2025 Flat Panel Display  
The Clock must first be set correctly since the Clock Phase  
settings are dependent on the main Clock setting.  
When using the controls, you will obtain the best results by using  
the adjustment pattern provided on the CD-ROM.  
When adjusting the Clock and Clock Phase values, if the monitor  
images become distorted, continue adjusting the values until the  
distortion disappears. To restore the factory settings, select Yes  
from the Factory Reset menu in the on-screen display.  
Recognizing Preset Display Resolutions  
The display resolutions listed below are the most commonly used  
modes and are set as factory defaults. This monitor automatically  
recognizes these preset modes and they will appear properly sized  
and centered on the screen.

Entering User Modes  
The video controller signal may occasionally call for a mode that  
is not preset if:  
You are not using a Compaq 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 18  
factory preset modes, there are four user modes that can be  
entered and stored.  
Energy Saver Feature  
When the monitor is in its normal operating mode, the monitor  
uses less than 70 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.  
User’s Guide  
17  
   
2025 Flat Panel Display  
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 5 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.

Congratulations!  
You have just purchased a TCO'99 approved and labelled

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.

Agency Regulatory Notices  
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**  
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.

Power Cord Set Requirements  
The monitor power supply is provided with Automatic Line  
Switching (ALS). This feature allows the monitor to operate on  
input voltages between 100-120V or 200-240V.  
The power cord set (flexible cord or wall plug) received with the  
monitor meets the requirements for use in the country where you  
purchased the equipment.  
If you need to obtain a power cord for a different country, you  
should purchase a power cord that is approved for use in that  
country.  
The power cord must be rated for the product and for the voltage  
and current marked on the product's electrical ratings label. The  
voltage and current rating of the cord should be greater than the  
voltage and current rating marked on the product. In addition, the  
cross-sectional area of the wire must be a minimum of 0.75 mm²  
or 18AWG, and the length of the cord must be between 6 feet  
(1.8 m) and 12 feet (3.6 m). If you have questions about the type  
of power cord to use, contact your Compaq authorized service  
provider.  
A power cord should be routed so that it is not likely to be walked  
on or pinched by items placed upon it or against it. Particular  
attention should be paid to the plug, electrical outlet, and the  
point where the cord exits from the product.
