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. 
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 15 
factory preset modes, there are ten user modes that can be entered 
and stored.

Technical Specifications 
Energy Saver Feature 
When the monitor is in its normal operating mode, the monitor 
uses less than 70 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 2 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). 
✎ The above energy saver feature only works when connected to 
computers that have energy saver 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.

Power Cord Set Requirements 
The monitor power supply is provided with Automatic Line 
Switching (ALS). This feature allows the monitor to operate on 
input voltages between 100-120V or 200-240V. 
The power cord set (flexible cord or wall plug) received with the 
monitor meets the requirements for use in the country where you 
purchased the equipment. 
If you need to obtain a power cord for a different country, you 
should purchase a power cord that is approved for use in that 
country. 
The power cord must be rated for the product and for the voltage 
and current marked on the product's electrical ratings label. The 
voltage and current rating of the cord should be greater than the 
voltage and current rating marked on the product. In addition, the 
cross-sectional area of the wire must be a minimum of 0.75 mm² 
or 18AWG, and the length of the cord must be between 6 feet 
(1.8 m) and 12 feet (3.6 m). If you have questions about the type 
of power cord to use, contact your HP authorized service 
provider. 
A power cord should be routed so that it is not likely to be walked 
on or pinched by items placed upon it or against it. Particular 
attention should be paid to the plug, electrical outlet, and the 
point where the cord exits from the product. 
For use in Japan: 
■	Please use the power cord received with the product. 
■	The power cord received with this product is not for use with 
other products.
