Entering User Modes
The video controller signal may occasionally call for a mode that is not preset if:
●You are not using a standard graphics adapter.
●You are not using a preset mode.
It this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen
display or HP Display Assistant software. Your changes can be made to any or all of these modes and
saved in memory. The monitor automatically stores the new setting, then recognizes the new mode just
as it does a preset mode. In addition to the 15 factory present modes, there are four user modes that
can be entered and stored.
Energy Saver Feature
When the monitor is in its normal operating mode, the monitor uses less than 25 watts (LE1901wi) or
40 watts (L1910i) or 28 watts (LE1911i) of power and the Power light is green.
The monitor also supports a reduced power state. The reduced power state will be entered into if the
monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon
detecting the absence of these signals, the monitor screen is blanked, the backlight is turned off, and
the power light is turned amber. When the monitor is in the reduced power state, the monitor will utilize
less than 1 watt of power. There is a brief warm up period before the monitor will return to its normal
operating mode.

into the reduced power state at a predetermined time. When the monitors Energy Saver utility causes
the monitor to enter the reduced power state, the power light blinks amber.
