Entering user modes
Under the following conditions, the video controller signal may occasionally call for a mode that is not preset:
● You are not using a standard graphics adapter.
● You are not using a preset mode.
If this occurs, you may need to readjust the parameters of the monitor screen by using the OSD. Your changes
can be made to any or all of these modes and saved in memory. The monitor automatically stores the new
setting, and then recognizes the new mode just as it does a preset mode. In addition to the factory preset
modes, at least eight user modes can be entered and stored.

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 o, 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.
