• Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.
Image persistence
• Image persistence is when a “ghost” of an image remains on the screen even after the monitor has been turned off.
Unlike CRT monitors, LCD monitors’ image persistence is not permanent. To alleviate image persistence, turn the
monitor off for as long as an image was displayed. If an image was on the monitor for one hour and a “ghost” of that
image remains, the monitor should be turned off for one hour to erase the image.
NOTE: As with all personal display devices, NEC-Mitsubishi Electronics Display recommends using a screen
saver at regular intervals whenever the screen is idle.
Image is unstable, unfocused or swimming is apparent
• Signal cable should be completely attached to the computer.
• Use the OSD Image Adjust controls to focus and adjust display by increasing or decreasing the fine total. When the
display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.
• Check the monitor and your display card with respect to compatibility and recommended signal timings.
• If your text is garbled, change the video mode to non-interlace and use 60Hz refresh rate.
LED on monitor is not lit (no green or amber colour can be seen)
• Power Switch should be in the ON position and power cord should be connected.
• Check the LED of AC adapter is ON.
• Make certain the computer is not in a power-saving mode (touch the keyboard or mouse).
Display image is not sized properly
• Use the OSD Image Adjust controls to increase or decrease the Coarse total.
• Check to make sure that a supported mode has been selected on the display card or system being used. (Please
consult display card or system manual to change graphics mode.)
Selected resolution is not displayed properly
• Use OSD Display Mode to enter Information menu and confirm that the appropriate resolution has been selected. If not,
select corresponding option.

Troubleshooting
TCO’95
TCO’95 demand requires that plastic components weighing more
than 25 grams must not contain organically bound chlorine and
bromine.
MultiSync LCD1920NX Black Model
Congratulations! You have just purchased a TCO’95
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.
Lead**
Why do we have environmentally labelled computers?
Lead can be found in picture tubes, display screens, solders and
capacitors. Lead damages the nervous system and in higher
doses, causes lead poisoning.
TCO’95 requirement permits the inclusion of lead since no
replacement has yet been developed.
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 the manufacturing. Since it has not been possible for
the majority of electronics equipment to be recycled in a
satisfactory way, 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 conventional electricity generation have a
negative effect on the environment (acidic and climate-influencing
emissions, radioactive waste, etc.), it is vital to conserve energy.
Electronics equipment in offices consume an enormous amount
of energy since they are often left running continuously.
Cadmium**
What does labelling involve?
CFCs (freons)
This product meets the requirements for the TCO’95 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), Naturskyddsforeningen (The Swedish
Society for Nature Conservation) and NUTEK (The National Board
for Industrial and Technical Development in Sweden).
The requirements cover a wide range of issues: environment,
ergonomics, usability, emission of electrical and magnetic fields,
energy consumption and electrical and fire safety.
The environmental demands concern 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 plan 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.
TCO’95 is a co-operative project between TCO (The Swedish
Confederation of Professional Employees),
Naturskyddsforeningen (The Swedish Society for Nature
Conservation) and NUTEK (The National Board for Industrial and
Technical Development in Sweden).
CFCs (freons) are sometimes used for washing printed circuit
boards and in the manufacturing of expanded foam for packaging.
CFCs break down ozone and thereby damage the ozone layer in
the stratosphere, causing increased reception on Earth of
ultraviolet light with consequent increased risks of skin cancer
(malignant melanoma).
The relevant TCO’95 requirement; Neither CFCs nor HCFCs may
be used during the manufacturing of the product or its packaging.
Cadmium is present in rechargeable batteries and in the
colourgenerating layers of certain computer displays. Cadmium
damages the nervous system and is toxic in high doses.
TCO’95 requirement states that batteries may not contain more
than 25 ppm (parts per million) of cadmium. The colourgenerating
layers of display screens must not contain any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays, switches, and
back-light systems, Mercury damages the nervous system and is
toxic in high doses.
TCO’95 requirement states that batteries may not contain more
than 25 ppm (parts per million) of mercury. It also demands that
no mercury is present in any of the electrical or electronics
components concerned with the display unit, except the back-light
system.
*Bio-accumulative is defined as substances which accumulate
within living organisms.
**Lead, Cadmium and Mercury are heavy metals which are
Bio-accumulative.

Environmental Requirements
Brominated flame retardants
Brominated flame retardants are present in printed circuit boards,
cables, wires, casings and housings. In turn, they delay the
spread of fire. Up to thirty percent of the plastic in a computer
casing can consist of flame retardant substances. These are
related to another group of environmental toxins, PCBs, which are
suspected to give rise to similar harm, including reproductive
damage in fisheating 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.

Lead**
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.
Lead can be found in picture tubes, display screens, solders and
capacitors. Lead damages the nervous system and in higher
doses, causes lead poisoning.
TCO’99 requirement permits the inclusion of lead since no
replacement has yet been developed.
Cadmium**
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 the manufacturing. Since it has not been possible for
the majority of electronics equipment to be recycled in a
satisfactory way, 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 conventional electricity generation have a negative
effect on the environment (acidic and climate-influencing
emissions, radioactive waste, etc.), it is vital to conserve energy.
Electronics equipment in offices consume an enormous amount
of energy since they are often left running continuously.
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).
The requirements cover a wide range of issues: environment,
ergonomics, usability, emission of electrical and magnetic fields,
energy consumption and electrical and fire safety.
The environmental demands concern 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 plan 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.
Cadmium is present in rechargeable batteries and in the
colourgenerating layers of certain computer displays. Cadmium
damages the nervous system and is toxic in high doses.
TCO’99 requirement states that batteries, the colourgenerating
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,
Mercury damages the nervous system and is toxic in high
doses.
TCO’99 requirement states that batteries may not contain any
Mercury. It also demands that no mercury is present in any of
the electrical or electronics components associated with the
display unit.
CFCs (freons)
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 consequent increased risks of skin cancer
(malignant melanoma).
The relevant TCO’99 requirement; Neither CFCs nor HCFCs
may be used during the manufacturing and assembly of the
product or its packaging.
*Bio-accumulative is defined as substances which accumulate
within living organisms.
**Lead, Cadmium and Mercury are heavy metals which are
Bio-accumulative.

Environmental Requirements
Flame retardants
Flame retardants are present in printed circuit boards, cables,
wires, casings and housings. In turn, they delay the spread of fire.
Up to thirty percent of the plastic in a computer casing can consist
of flame retardant substances. Most flame retardants contain
bromine or chloride and these are related to another group of
environmental toxins, PCBs, which are suspected to give rise to
severe health effects, including reproductive damage in fisheating
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.
TCO’99 demand requires that plastic components weighing more
than 25 grams must not contain flame retardants with organically
bound chlorine and bromine. Flame retardants are allowed in the
printed circuit boards since no substitutes are available.
