Troubleshooting  
This LCD Monitor has pre-adjusted using factory standard VGA timings. Due to the output  
timing differences among various VGA cards in the market, users may initially experience  
an unstable or unclear display whenever a new display mode or new VGA card is selected.  
Attention  
This LCD Monitor Supports Multiple VGA Modes.  
Refer to the Standard Timing Table for a listing of modes supported by this LCD Monitor.  
PROBLEM  
Picture is unclear and  
unstable  
Check Items  
The picture is unclear and unstable, please perform the  
following steps:  
1. Enter PC to “Shut Down Windows” status while you’re in  
MS-Windows environment.  
2. Check the screen to see if there’s any black vertical stripes  
appear. If there are, take advantage of the “Clock”  
function in OSD menu and adjust (by increment or  
decrement numbers) until those bars disappear.  
3. Move to “Phase” function in OSD menu again and adjust  
the monitor screen to its most clear display.  
4. Click “No” on “Shut Down Windows” and back to the  
normal PC operating environment.  
If there’s no picture on the LCD Monitor, please perform the  
following steps:  
There is no picture on  
LCD Monitor  
1. Make sure the power indicator on the LCD Monitor is ON,  
all connections are secured, and the system is running on  
the correct timing. Refer to “Supported Timing List” for  
information on timing.  
2. Turn off the LCD Monitor and then turn it back on again.  
If there is still no picture, press the Adjustment Control  
button several times.  
3. If step 2 doesn’t work, connect your PC system to another  
external CRT. If your PC system Functions properly with a  
CRT Monitor but it does not function with the LCD  
Monitor, the output timing of the VGA card may be out of  
the LCD’s synchronous range. Please change to an  
alternative mode listed in the Supported Timing List or  
replace the VGA card, and then repeat steps 1 and 2.  
If you have chosen an output timing that is outside of the  
LCD Monitor’s synchronous range (Horizontal: 24 ~ 80 KHz  
and Vertical: 49 ~ 75 Hz), the OSD will display a “Out of  
Range” message. Choose a mode that is supported by your  
LCD Monitor.  
There is no picture on  
LCD Monitor  
Also, if the signal cable is not connected to LCD monitor at all  
or properly, the monitor screen will display a message “No  
Input Signal”.

Interface Frequency  
The following frequency range is the working period. If the entered mode between below  
period but not match the frequency of supported timing, display optimization not be  
assured. If the entered mode is out of the working period, the display will be blanking  
(just show “out of range”) then go to power saving.  
Basically, mode judgment is regardless the sync polarity except both or more modes that  
are all belong to the supported timing list and could be judged by sync polarity only.  
At the meantime, real entered frequency of the supported timing is not requested exactly.  
Normalization of VGA card’s deviation will be acceptable.

TCO'99  
Congratulations!  
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 also to the further development of environmentally adapted electronics products.  
Why do we have environmentally labeled computers?  
In many countries, 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 (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 labeling involve?  
This product meets the requirements for the TCO'99 scheme which provides for 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) 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.  
Labeled 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  
bio-accumulative* 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 labeled 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.  
* Bio-accumulative is defined as substances which accumulate within living organisms  
** Lead, Cadmium and Mercury are heavy metals which are Bio-accumulative.
