WARNING! To reduce the risk of electric shock or damage to the equipment:
• Plug the power cord into an AC outlet that is easily accessible at all times.
• Disconnect power from the computer by unplugging the power cord from the AC outlet.
• If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded (earthed)
3-pin outlet. Do not disable the power cord grounding pin, for example, by attaching a 2-pin adapter.
The grounding pin is an important safety feature.
For your safety, do not place anything on power cords or cables. Arrange them so that no one may
accidentally step on or trip over them.
To reduce the risk of serious injury, read the Safety & Comfort Guide. It describes proper workstation,
setup, posture, and health and work habits for computer users, and provides important electrical and
mechanical safety information. This guide is located on the Web at http://www.hp.com/ergo.
CAUTION: For the protection of the monitor, as well as the computer, connect all power cords for
the computer and its peripheral devices (such as a monitor, printer, scanner) to some form of surge
protection device such as a power strip or Uninterruptible Power Supply (UPS). Not all power strips
provide surge protection; the power strips must be specifically labeled as having this ability. Use a power
strip whose manufacturer offers a Damage Replacement Policy so you can replace the equipment, if
surge protection fails.
Use the appropriate and correctly sized furniture designed to properly support your HP LCD monitor.
WARNING! LCD monitors that are inappropriately situated on dressers, bookcases, shelves, desks,
speakers, chests, or carts may fall over and cause personal injury.
Care should be taken to route all cords and cables connected to the LCD monitor so that they cannot be
pulled, grabbed, or tripped over.
Be sure that the total ampere rating of the products connected to the AC outlet does not exceed the
current rating of the outlet, and that 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 AC outlet that you can easily reach. Disconnect the monitor by grasping the
plug firmly and pulling it from the AC outlet. Never disconnect the monitor by pulling the cord.
Do not drop the monitor or place it on an unstable surface.
NOTE: This product is suitable for entertainment purposes. Consider placing the monitor in a controlled
luminous environment to avoid interference from surrounding light and bright surfaces that may cause
disturbing reflections from the screen.

8 1 Getting Started
HP Watermark and Image Retention Policy
The IPS (In-Plane Switching) monitor models are designed with IPS display technology which provides
ultra-wide 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.
Installing a security cable
You can secure the monitor to a fixed object with an optional cable lock available from HP.

You may also optimize the screen performance for the VGA (analog) input at any time by using the
auto button on the monitor (see your model’s user guide for the specific button name) and the autoadjustment pattern software utility on www.hp.com/support.
Do not use this procedure if the monitor is using an input other than VGA. If the monitor is using a VGA
(analog) input, this procedure can correct the following image quality conditions:
• Fuzzy or unclear focus
• Ghosting, streaking or shadowing effects
• Faint vertical bars
• Thin, horizontal scrolling lines
• An off-center picture
To use the auto-adjustment feature:
1. Allow the monitor to warm up for 20 minutes before adjusting.
2. Press the Menu button, and then select Image Control>Auto-Adjustment from the OSD menu. If
the result is not satisfactory, continue with the procedure.
3. Display the auto-adjustment setup test pattern on your screen.
• Download the auto-adjustment test pattern utility from http://www.hp.com/support.
4. Press the ESC key or any other key on the keyboard to exit the test pattern.

NOTE: You may need to install the digitally signed monitor .INF and .ICM files from
in the event of an installation error.
The Clock must first be set correctly since the Phase settings are dependent on the main Clock setting.
Use these controls only when the auto-adjustment function does not provide a satisfactory image.
• Clock—Increases/decreases the value to minimize any vertical bars or stripes visible on the screen
background.
• Phase—Increases/decreases the value to minimize video flickering or blurring.
NOTE: When using the controls, you will obtain the best results by using the auto-adjustment pattern
software utility from www.hp.com/support.
When adjusting the Clock and Phase values, if the monitor images become distorted, continue adjusting
the values until the distortion disappears. To restore the factory settings, select Yes from the Factory
Reset menu in the on-screen display.

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.
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.
