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 xed 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 o the monitor when it is not in use or use the power management setting, if supported on your system, to turn o the display when the system is idle.

Using Auto-Sleep Mode

The monitor supports an OSD (on-screen display) menu option called Auto-Sleep Mode that allows you to enable or disable a reduced power state for the monitor. When Auto-Sleep Mode is enabled (enabled by default), the monitor will enter a reduced power state when the host PC signals low power mode (absence of either horizontal or vertical sync signal).
Upon entering this reduced power state (sleep mode), the monitor screen is blanked, the backlight is turned o and the power LED indicator turns amber. The monitor draws less than 0.5 W of power when in this reduced power state. The monitor will wake from the sleep mode when the host PC sends an active signal to the monitor (for example, if you activate the mouse or keyboard).
You can disable Auto-Sleep Mode in the OSD. Press one of the four front bezel buttons to activate the buttons, and then press the Menu button to open the OSD. In the OSD menu select Power Control > Auto-Sleep Mode > O.

Adjusting to Low Blue Light Mode

Decreasing the blue light emitting from the display reduces the blue light exposure to your eyes. The monitor provides a setting to reduce blue light output and create a more relaxing and less stimulating image while reading content on the screen. To make this adjustment, press the Menu button, select Color Control > Low Blue Light. Press the (ok) button to Save and Return.

Using the auto-adjustment function (analog input)

When you rst set up the monitor, conduct a Factory Reset of the computer, or change the resolution of the monitor, the Auto-Adjustment feature automatically engages, and attempts to optimize your screen for you.
You may also optimize the screen performance for the VGA (analog) input at any time by using the auto­adjustment button on the monitor and the auto-adjustment pattern software utility on the optical disc provided (select models only).
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 eects
Faint vertical bars
Thin, horizontal scrolling lines
An o-center picture
To use the auto-adjustment feature:
1. Allow the monitor to warm up for 20 minutes before adjusting.
2. Press the auto-adjustment button on the monitor front bezel.
You can also 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. Insert the optical disc into the optical drive. The optical disc menu is displayed.
4. Select Open Auto-Adjustment Utility. The setup test pattern is displayed.
5. Press the auto button on the monitor front bezel to produce a stable, centered image.
6. Press the ESC key or any other key on the keyboard to exit the test pattern.
NOTE: The auto-adjustment test pattern utility can be downloaded from http://www.hp.com/support.

Optimizing image performance (analog input)

Two controls in the on-screen display can be adjusted to improve image performance: Clock and Phase (available in the OSD menu).
NOTE: The Clock and Phase controls are adjustable only when using an analog (VGA) input. These controls
are not adjustable for digital inputs.
The Clock must rst 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 ickering or blurring.
NOTE: When using the controls, you will obtain the best results by using the auto-adjustment pattern
software utility provided on the optical disc.
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.
To eliminate vertical bars (Clock):
1. Press the Menu button on the monitor front bezel to open the OSD menu, and then select Image Control
> Clock and Phase.
2. Use the Function buttons on the monitor front bezel that display up and down arrow icons to eliminate
vertical bars. Press the buttons slowly so that you do not miss the optimum adjustment point.
3. After adjusting the Clock, if blurring, ickering, or bars appear on the screen, proceed to adjust the
Phase.
To remove ickering or blurring (Phase):
1. Press the Menu button on the monitor front bezel to open the OSD menu, and then select Image Control
> Clock and Phase.
2. Press the Function buttons on the monitor front bezel that display up and down arrow icons to eliminate
ickering or blurring. Flickering or blurring may not be eliminated, depending on the computer or graphics controller card installed.
To correct screen position (Horizontal Position or Vertical Position):
1. Press the Menu button on the monitor's front bezel to open the OSD menu, and then select Image
Position.
Optimizing image performance (analog input) 25

2. Press the Function buttons on the monitor front bezel that display up and down arrow icons to properly
adjust the position of the image in the display area of the monitor. The Horizontal Position shifts the image left or right; the Vertical Position shifts the image up and down.

Button lockouts

Holding down the Power button or Menu button for ten seconds will lock out the functionality of that button. You can restore the functionality by holding the button down again for ten seconds. This functionality is only available when the monitor is powered on, displaying an active signal, and the OSD is not active.

5 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 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.
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 o 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 surface cleaning, use 100% isopropyl alcohol to avoid any residue or damage.
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.

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.
