Energy saver feature
The monitor supports a reduced power state. The reduced power state is initiated if the monitor detects the
absence of either the horizontal sync signal or the vertical sync signal. Upon detecting the absence of these
signals, the monitor screen is blank, the backlight is turned off, and the power light turns amber. When the
monitor is in the reduced power state, the monitor uses <0.5 W of power. There is a brief warm-up period
before the monitor returns to its normal operating state.
See the computer manual for instructions on setting the energy saver mode (sometimes called power
management feature).
NOTE:
This power saver feature works only when the monitor is connected to a computer that has energy
saver features.
By selecting the settings in the monitor Sleep Timer utility, you can also program the monitor to initiate the
reduced power state at a predetermined time. When the monitor Sleep Timer utility initiates the reduced
power state, the power light blinks amber.
