A third-party certification according to ISO 14024
Say hello to a more sustainable
product
IT products are associated with a wide range of sustainability risks throughout their life cycle.
Human rights violations are common in the factories. Harmful substances are used both in
products and their manufacture. Products can often have a short lifespan because of poor
ergonomics, low quality and when they are not able to be repaired or upgraded.
This product is a better choice. It meets all the criteria in TCO Certified, the world's most
comprehensive sustainability certification for IT products. Thank you for making a
responsible product choice, that help drive progress towards a more sustainable future!
Criteria in TCO Certified have a life-cycle perspective and balance environmental and social
responsibility. Conformity is verified by independent and approved verifiers that specialize
in IT products, social responsibility or other sustainability issues. Verification is done both
before and after the certificate is issued, covering the entire validity period. The process also
includes ensuring that corrective actions are implemented in all cases of factory non-
conformities. And last but not least, to make sure that the certification and independent
verification is accurate, both TCO Certified and the verifiers are reviewed regularly.

Chapter 2. Adjusting and Using the Display
This section describes how to adjust and use this display.
Comfort and Assistance Functions
Good ergonomic designs are important for the comfortable use of your personal
computer. Your workplace and the equipment you use should be arranged
appropriately for your personal needs and the type of work you do. In addition,
healthy work habits can help you achieve optimal efficiency and comfort when using
a computer.
Arrange Your Working Area
Use a work surface of the right height and enough work area so that you can work
comfortably.
Arrange your work area according to the way you use materials and equipment. Keep
frequently used materials neatly organized in your work area, and place frequently
used items (such as a computer mouse or telephone) in an easily accessible location.
The placement and setup of equipment are very important to your work posture. The
following topics describe how to optimize equipment settings to achieve and maintain
a good working posture.
Placing and Viewing the Display
For comfortable viewing of the display, the following factors should be considered
when placing and adjusting computer displays:
Viewing Distance: The recommended viewing distance between your eyes
and the display screen is 1.5X the screen diagonal. Solutions to meet this
required distance in a small office include: keeping the desk a certain distance
from the wall or partition to allow space for the display, using a flat panel or
smaller display and keeping the display in the corner of the desk, or placing
the keyboard in an adjustable drawer board to create a deeper work surface.
Display Height: If your display is not height-adjustable, place your head and
neck in a natural, comfortable (vertical or upright) position. If your display is
not height-adjustable, you can place a book or other sturdy object under the
base of the display to achieve the desired height. The general rule is to sit
comfortably with the top of the display screen at eye level or slightly lower.
However, it is important to optimize the height of the display so that the
relative position between the eyes and the center of the display provides the
right visual distance and a comfortable viewing experience when the eye
muscles are relaxed.
Tilt: Adjusting the tilt of your display optimizes the appearance of your screen
content and keeps your head and neck in the best possible position.
Regular Location: Place the display in such a way that overhead lighting or
nearby windows do not cause glare or reflection on the screen.
2-1 Display User Guide
Here are some additional tips for comfortable viewing of your display:
• Use adequate lighting for the type of work you do.
• Use display brightness, contrast, and image controls (if available) to optimize the
image on the screen for your visual needs.
• Keep the display screen clean so that you can see the content clearly.
Long periods of focused visual activity tend to strain the eyes. Be sure to periodically
move away from the display screen and gaze at a distant object to relax your eye
muscles. If you have any questions about eye strain or visual discomfort, consult
vision care professional for advice.
Tips on Healthy Work Habits
The following is a summary of some important factors that are useful to keep you
comfortable and productive while using your computer.
Good posture comes from equipment placement: The layout of your work area
and the placement of your computer equipment can have a significant impact
on your posture while using the computer. Be sure to follow the tips listed in "
Arrange Your Working Area" on pages 2-1 to optimize the placement and
orientation of your equipment so you can maintain comfortable posture and
efficiency. In addition, be sure to use the adjustment features of your computer
components and office furniture to meet your needs, and adjust them over time
as your needs change.
Slight changes in posture help keep you comfortable: the longer you sit in
front of a computer, the more important it becomes to pay attention to your
work posture. Avoid maintaining one posture for long periods. Regular slight
changes in posture can help prevent possible discomfort. Use the adjustment
function provided by office furniture or equipment to adapt to changes in
posture.
Regular short breaks help ensure healthy computing: Because computing is
primarily a static activity, it is especially important to take short breaks during
the workday. Take regular breaks to stand in front of your work area, stretch
your limbs, walk around or have a drink, or otherwise take a short break from
using the computer. Taking short breaks during work allows for changes in
body posture that can help you stay comfortable and productive while
working.

Energy Star is an energy saving program for consumer electronics led by the U.S.
government.
It was launched in 1992 by EPA and DOE to reduce energy consumption and greenhouse gas
emissions. Energy Star logo is a symbol of energy conservation and environmental
protection.
It improves the concept of energy efficiency of consumers and manufacturers, and
effectively guides the market.
The regulation of Energy Star improves energy efficiency and reduces air pollution by using
more energy-efficient equipment in homes, offices and factories. One way to achieve this
goal is to use management to reduce energy consumption when products are not in use.
The default settings for monitors conform to Energy Star certification. Any changes by users
for more features and functionalities may increase power consumption, which will exceed
the limitation of Energy Star’s standard. If the user changes the options related to energy
efficiency when using, such as brightness, color mode, etc., select All Reset Factory or
choose the Energy Star option, the power consumption will be restored to the energy
efficiency with Energy Star standard.
For more information, please refer to (www.energystar.gov/products). All products of
Energy Star will be posted online and can be accessed directly by governments, public
institutions and consumers.

Select Supported Display Modes
The display mode used by the display is controlled by the computer. Therefore, you should
refer to the computer's documentation for detailed information on how to change the display
mode.
When the display mode is changed, the image size, position, and shape may change. This is
normal and the image can be readjusted using the automatic image settings and image
controls.
Unlike CRT displays, which require high refresh rates to minimize flicker, LCD or flat
panel technology is inherently flicker-free.
Note: If the system has previously been used in conjunction with a CRT display and is
currently configured for a display mode outside the range of that display, you may need to
temporarily reconnect the CRT display until the system has been reconfigured; it is best to
set it to 1600x900 (60Hz), the normal display mode.
The display modes shown below are factory optimized.
