ENERGY STAR is a consumer electronics energy efficiency program led by the U.S.
government. It was launched at the Department of Energy to reduce energy consumption
and greenhouse gas emissions. The ENERGY STAR logo is a symbol of energy
efficiency and environmental protection. It has improved the concept of energy
efficiency among consumers and manufacturers, and effectively guided the market. The
“ENERGY STAR Regulations” improve energy efficiency and reduce air pollution
through the use of 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 of the monitor are ENERGY STAR
qualified. Any changes made by the user to more features and functions can increase
power consumption, which would exceed the limits of the ENERGY STAR standard. If
the user changes options related to energy efficiency while in use, such as brightness,
color mode, etc., selecting Reset Factory All or selecting the ENERGY STAR option
will restore energy consumption to ENERGY STAR-compliant energy efficiency.
For more information, see (www.enercystar.gov/products). All ENERGY STAR
products will be posted online and directly accessible to governments, public agencies,
and consumers.
