The monitor automatically scans the signal inputs for an active input and uses that input for the screen.
HP watermark and image retention policy
The IPS monitor models are designed with IPS (In-Plane Switching) display technology which provides ultrawide viewing angles and advanced image quality. IPS monitors are suitable for a wide variety of advanced
image quality applications. This panel technology, however, is not suitable for applications that exhibit static,
stationary or fixed images for long periods of time without the use of screen savers. These types of
applications may include camera surveillance, video games, marketing logos, and templates that are
displayed on the screen for a prolonged period of time. Static images may cause image retention damage
that could look like stains or watermarks on the monitor's screen.
Monitors in use for 24 hours per day that result in image retention damage are not covered under the HP
warranty. To avoid image retention damage, always turn off the monitor when it is not in use or use the
power management setting, if supported on your system, to turn off the display when the system is idle.

The .ICM files are data files that are used in conjunction with graphics programs to provide consistent color
matching from monitor screen to printer, or from scanner to monitor screen. This file is activated from within
graphics programs that support this feature.
NOTE: The ICM color profile is written in accordance with the International Color Consortium (ICC) Profile
Format specification.
Installing the .INF and .ICM files
After you determine that you need to update, you can install the .INF and .ICM files from the optical disc or
download them.
Installing from the optical disc

4 Maintaining the monitor
Maintenance guidelines
●
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.
●
Turn the monitor off when not in use. You can substantially increase the life expectancy of the monitor
by using a screen saver program and turning off 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.
●
Keep the monitor in a well-ventilated area, away from excessive light, heat, or moisture.
●
When removing the monitor stand, you must lay the monitor facedown on a soft area to prevent it from
getting scratched, defaced, or broken.
Cleaning the monitor
1. Turn off the monitor and disconnect power from the computer by unplugging the power cord from the
AC outlet.
2. Dust the monitor by wiping the screen and the cabinet with a soft, clean antistatic cloth.
3. For more difficult cleaning situations, use a 50/50 mix of water and isopropyl alcohol.
CAUTION: Spray the cleaner onto a cloth and use the damp cloth to gently wipe the screen surface. Never
spray the cleaner directly on the screen surface. It may run behind the bezel and damage the electronics.
CAUTION: Do not use cleaners that contain any petroleum-based materials such as benzene, thinner, or
any volatile substance to clean the monitor screen or cabinet. These chemicals may damage the monitor.
Shipping the monitor
Keep the original packing box in a storage area. You may need it later if you move or ship the monitor.

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.
28 Appendix A Technical specifications
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 off, 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.
