TCO Information  
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. With the growing manufacture and  
usage of electronic equipment throughout the world, there is a recognized concern for the  
materials and substances used by electronic products with regards to their eventual recycling  
and disposal. By proper selection of these materials and substances, the impact on the  
environment can be minimized.  
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.  
Electronic equipment in offices is often left running continuously, resulting in unnecessary  
consumption of large amounts of energy and additional power generation. From the standpoint  
of carbon dioxide emissions alone, it is vital to save energy.  
What does labelling involve?  
The product meets the requirements for the TCO’99 scheme which provides for international  
and environmental labelling of personal computers and/or displays. 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: ecology, ergonomics, emission of  
electrical and magnetical fields, energy consumption and electrical safety.  
Ecological criteria impose restrictions on the presence and use of heavy metals, brominated  
and chlorinated flame retardants, and other substances. The product must be prepared for  
recycling and the manufacturing site(s) shall be certified according to ISO14001 or EMAS  
registered.  
Energy requirements include a demand that the system unit 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 system unit shall be reasonable for the user.  
Labelled products must meet strict environmental demands, for example, in respect of the  
reduction of electrical and magnetical fields as well as work load and visual ergonomics.

Ecological requirements  
Flame retardants  
Flame retardants may be present in printed wiring board laminates, cables, and housings. Their  
purpose is to prevent, or at least to delay the spread of fire. Up to 30% by weight of the plastic  
in a computer casing can consist of flame retardant substances. Many flame retardants contain  
bromine or chlorine, and these flame retardants are chemically related to PCBs  
(polychlorinated biphenyls). Both the flame retardants containing bromine or chlorine and the  
PCBs are suspected of giving rise to health effects, including reproductive damage in fish-  
eating birds and mammals, due to the bio-accumulative* processes when not disposed of in  
accordance with strict standards for disposal.  
TCO’99 requires that plastic components weighing more than 25 grams shall not contain flame  
retardants with organically bound bromine or chlorine. Flame retardants are allowed in the  
printed wiring board laminates due to the lack of commercially available alternatives.  
Cadmium**  
Cadmium is present in rechargeable batteries and in the colour-generating layers of certain  
computer displays. TCO’99 requires that batteries, the colour-generating layers of display  
screens, and the electrical or electronics components shall not contain any cadmium.  
Mercury**  
Mercury is sometimes found in batteries, relays and switches. TCO’99 requires that batteries  
shall 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.  
Lead**  
Lead can be found in picture tubes, display screens, solders and capacitors. TCO’99 permits  
the use of lead due to the lack of commercially available alternatives, but in future  
requirements TCO Development aims at restricting the use of lead.  
* Bio-accumulative is defined as substances which accumulate in living organisms.  
**Lead, Cadmium and Mercury are heavy metals which are bio-accumulative.

Using the LCD Display  
Setting the Timing Mode  
Setting the timing mode is important for maximizing the quality of the screen image and  
minimizing eye strain. The timing mode consists of the resolution (example 1280 x 1024) and  
refresh rate (or vertical frequency; example 60 Hz). After setting the timing mode, use the  
OSD (On-screen Display) controls to adjust the screen image.  
For the best picture quality set your LCD display timing mode to:  
VESA 1280 x 1024 @ 60Hz.  
To set the Timing Mode:  
1. Set the resolution: Right-click on the Windows desktop > Properties > Settings > set the  
resolution.  
2. Set the refresh rate: See your graphic card's user guide for instructions.  
WARNING: Do not set the graphics card in your computer to exceed the maximum refresh  
rate of 75Hz; doing so may result in permanent damage to your LCD display.  
OSD and Power Lock Settings  
OSD Lock: Press and hold [1] and the up arrow S for 10 seconds. If any buttons are  
pressed the message OSD Locked will display for 5 seconds.  
OSD Unlock: Press and hold [1] and the up arrow S again for 10 seconds.  
Power Button Lock: Press and hold [1] and the down arrow T for 10 seconds. If the  
power button is pressed the message Power Button Locked will display for 5 seconds. With  
or without this setting, after a power failure, your LCD display’s power will automatically  
turn ON when power is restored.  
Power Button Unlock: Press and hold [1] and the down arrow T again for 10 seconds.

Do the following to adjust the display setting:  
1. To display the Main Menu, press button [1].  
NOTE: All OSD menus and adjustment screens disappear automatically after about 15  
seconds. This is adjustable through the OSD timeout setting in the setup menu.

3. After the desired control is selected, press button [2]. A control screen like the one shown  
below appears.  
The command line at the bottom of the  
control screen tells what to do next from  
this screen. You can toggle between control  
screens, adjust the selected option, or exit  
the screen.  
4. To adjust the control, press the up S or down T buttons.  
5. To save the adjustments and exit the menu, press button [1] twice.  
The following tips may help you optimize your display:  
• Adjust the computer's graphics card so that it outputs a 1280 x 1024 @ 60Hz video signal to  
the LCD display. (Look for instructions on “changing the refresh rate” in the graphic card's  
user guide.)  
• If necessary, make small adjustments using H. POSITION and V. POSITION until the  
screen image is completely visible. (The black border around the edge of the screen should  
barely touch the illuminated “active area” of the LCD display.)

Troubleshooting  
No power  
• Make sure power button (or switch) is ON.  
• Make sure A/C power cord is securely connected to the LCD display.  
• Plug another electrical device (like a radio) into the power outlet to verify that the outlet is  
supplying proper voltage.  
Power is ON but no screen image  
• Make sure the video cable supplied with the LCD display is tightly secured to the video  
output port on the back of the computer. If the other end of the video cable is not attached  
permanently to the LCD display, tightly secure it to the LCD display.  
• Adjust brightness and contrast.  
• If you are using an Macintosh older than G3, you need a Macintosh adapter.  
Wrong or abnormal colors  
• If any colors (red, green, or blue) are missing, check the video cable to make sure it is  
securely connected. Loose or broken pins in the cable connector could cause an improper  
connection.  
• Connect the LCD display to another computer.  
• If you have an older graphics card, contact ViewSonic® for a non-DDC adapter.  
Control buttons do not work  
• Press only one button at a time.
