TCO certied
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.

• The monitor should be operated only from the type of power source indicated
on the label. If you are not sure of the type of power supply to your home,
consult your dealer or local power company.
• Use the appropriate power plug which complies with your local power standard.
• Do not overload power strips and extention cords. Overloading can result in re

Care & Cleaning
• Before you lift or reposition your monitor, it is better to disconnect the cables
and power cord. Follow the correct lifting techniques when positioning the
monitor. When lifting or carrying the monitor, grasp the edges of the monitor.
Do not lift the display by the stand or the cord.
• Cleaning. Turn your monitor off and unplug the power cord. Clean the monitor
surface with a lint-free, non-abrasive cloth. Stubborn stains may be removed
with a cloth dampened with mild cleaner.
• Avoid using a cleaner containing alcohol or acetone. Use a cleaner intended
for use with the monitor. Never spray cleaner directly on the screen, as it may
drip inside the monitor and cause an electric shock.
The following symptoms are normal with the monitor:
• You may find slightly uneven brightness on the screen depending on the
desktop pattern you use.
• When the same image is displayed for hours, an afterimage of the previous
screen may remain after switching the image. The screen will recover slowly or
you can turn off the Power Switch for hours.
• When the screen becomes black or ashes, or cannot work anymore, contact
your dealer or service center to x it. Do not repair the screen by yourself!

to dynamically adjust display refresh rate based on typical content frame
rates for power efcient, virtually stutter free and low-latency display
update.

ports to charge external devices when the monitor enters power
saving mode.
