Power Consumption

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 1024 x 768

or the frequency refresh rates of 31-69kHz horizontal or 56-85Hz 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:
