4 Maintaining the monitor
Maintenance guidelines
To enhance the performance and extend the life of the monitor:
●
Do not open the monitor cabinet or attempt to service this product yourself. Adjust only those controls
that are covered in the operating instructions. If the monitor is not operating properly or has been
dropped or damaged, contact an authorized HP dealer, reseller, or service provider.
●
Use only a power source and connection appropriate for this monitor, as indicated on the label/back
plate of the monitor.
●
Be sure the total ampere rating of the products connected to the outlet does not exceed the current
rating of the electrical outlet, and the total ampere rating of the products connected to the cord does
not exceed the rating of the cord. Look on the power label to determine the ampere rating (AMPS or A)
for each device.
●
Install the monitor near an outlet that you can easily reach. Disconnect the monitor by grasping the plug
rmly and pulling it from the outlet. Never disconnect the monitor by pulling the cord.
●
Turn the monitor o when not in use. You can substantially increase the life expectancy of the monitor
by using a screen saver program and turning o the monitor when not in use.
NOTE: Monitors with a “burned-in image” are not covered under the HP warranty.
●
Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked or
covered. Never push objects of any kind into cabinet slots or other openings.
●
Do not drop the monitor or place it on an unstable surface.

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.
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, there are at least 10 user modes that can be entered and stored.
Entering user modes 27
Energy saver feature
The monitors support a reduced power state. The reduced power state will be entered into 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 blanked, the backlight is turned o, and the power light is
turned amber. When the monitor is in the reduced power state, the monitor will utilize 0.5 watts of power.
There is a brief warm-up period before the monitor will return to its normal operating mode.
Refer to the computer manual for instructions on setting energy saver features (sometimes called power
management features).
NOTE: The above power saver feature only works when the monitor is connected to a computer that has
energy saver features.
By selecting the 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.
