Usin g t h e Ener gy S aver Featur e

When the monitor is in its normal operating mode, the monitor uses less than 75 watts 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 3 watts of power. There is a brief warm up period before the monitor will return to its normal operating mode.

Refer to your computer manual for instructions on setting energy saver features (sometimes called power management features).

By selecting settings in the monitor s Energy Saver utility, you can also program the monitor to enter into the reduced power state at a predetermined time. When the monitor s Energy Saver utility causes the monitor to enter the reduced power state, the Power light blinks amber.

En terinGUs er Mod es

The video controller signal may occasionally call for a mode that is not preset if:

You are not using a Hewlett Packard 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 on-screen display. 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 18 factory preset modes, there are four user modes that can be entered and stored.

Connection to PC

S ettin g U p th e Monitor

To set up the monitor, ensure that the power is turned off to the monitor, computer system, and other attached devices, then follow these steps:

1. Place the monitor in a convenient, well-ventilated location near your computer.

2. Connect one end of the monitor signal cable to the video connector on the rear panel of the computer, and the other end to the back of the monitor.

3. Connect the power cable to the back of the monitor, and the other end of the power cable to an electrical wall outlet.
