Energy Saving Design
This monitor complies with the EPA's Energy Star program, which is a
program designed to have manufacturers of computer equipment
build circuitry into their products to reduce power consumption during
time of non-use.
This monitor also goes into its energy saving mode if you exceed the
monitor's operating limits, such as the maximum resolution of
1280x1024 or the frequency refresh rates of 30-70kHz horizontal or
50-160Hz vertical. When this monitor is used with a Green or EPA
Energy Star PC, or a PC with a screen blanking software following the
VESA Display Power Management Signalling (DPMS) protocol, this
monitor can conserve significant energy by reducing power
consumption during periods of non-use. When the PC goes into the
energy saving mode, the monitor will go into a suspended operation
state, indicated by the Power LED light changing from a green color
to an amber color. After an extended period in the suspended mode,
the monitor will then enter a semi-OFF mode to conserve more
energy. In the semi-OFF mode or DPMS OFF mode as we call it in
our specifications, the Power LED will still show an amber color.
When you awaken your PC by hitting a key or moving the mouse, the
monitor will also awaken to its normal operating mode, indicated by
the green Power LED light. By following these conventions, the power
consumption can be reduced to the following levels:
