Your monitor provides for more than one source of input. It will scan the various inputs to find an active
one and display that image. You can change sources manually, using the SOURCE button on the front
panel. The scanning order is initially set to DisplayPort, DVI-D, HDMI, VGA, making DisplayPort the
default source of video.
Some models give you control of the scanning order and default source through an On-Screen Display
(OSD) menu. If your front panel has a menu (

) button, it provides an OSD. The OSD also lets you
If the monitor is not receiving any input, it will go into low power mode (“sleep”) and the LED on the
front will turn from blue to amber. This means that the monitor will sleep when the computer does,
unless it has some other source of input. You can send it into low-power mode using the power (
)
button on the front. The OSD lets you put sleeping and waking on a timer or stay awake all the time
(not recommended).
Your monitor displays its state through the LED on the front panel and through messages on the screen.
These indicators vary from one model to another, but all use the following LED indicators:
Blue – normal operation
●
●
●
●
Amber – low-power mode
Flashing blue – the input calls for higher resolution than the monitor can provide
Flashing amber – timed sleep, that is, the monitor is in low-power mode and will awaken on a
timer
No light – normal operation or power off
●
In addition to these indicators, some models use screen messages as well, detailed later in this chapter.
Image quality is well-controlled with digital inputs. For analog input, various tools are provided for
adjusting the quality: a software utility, an auto-adjust function, and options in the OSD.
ZR2040w and ZR2240w Model
The order in which these monitors scan the inputs begins with the DisplayPort, making it the default
input. If DisplayPort is inactive, the monitor will scan for an active input in this order: DVI-D, HDMI
(ZR2240w only), VGA. You can change the current input, the default source, and the scan order

Pressing the Power button,
, puts the monitor in low power mode. (To turn power off completely, use
the switch on the rear of the panel.) The monitor also enters low-power mode when there is no video
signal input.
When the monitor is first powered on, the LED turns blue and remains blue for about half a minute. It
then turns off. If the monitor receives a signal outside its range (e.g., too high a frequency), the LED
flashes blue continuously.
This model does not use an OSD or on-screen messages.
Using the On-Screen Display Menu (Select Models)
The On-Screen Display (OSD) menu gives you choices for operating your monitor. Not all menu options
below are available on all models. For example, monitors with no analog input do not show menus
specific to analog images. The ZR2740w does not use an OSD. Models that use an OSD have a menu
(
) button on the front.
NOTE: If there is a problem with the display settings, try resetting the settings to the factory defaults
by opening the OSD and selecting Factory Reset from the OSD menu.
To access the OSD, do the following:
1. If the monitor is not already on, press the Power button to turn on the monitor.
2. Press the Menu button on the monitor's front panel.
You will see a menu of options and submenus.
3. To navigate through the menu, press the + (Plus) button on the monitor's front panel to scroll up, or
the — (Minus) button to scroll down.
4. To select an item from the OSD Menu, use the + or — buttons to scroll to and highlight your
selection, then press the OK button to select that function.
5. Adjust the item using the + or — buttons on the front panel to adjust the scale.
6. After adjusting the function, select Save and Return, or Cancel if you don't want to save the
setting, then select Exit from the Main Menu. The Save and Return option is only active if you
change a menu item.
NOTE: If the buttons remain untouched for 30 seconds (factory default) while displaying a menu, the
firmware will save the current adjustments and exit. Also, if the video controller changes video mode
while the OSD is active, the current (adjusted) settings will not be saved, the OSD will be turned off,
and the new mode will be displayed.
OSD Menu Selections
Below are the submenus of the OSD and their options. Not all models will display all submenus. For
example, a monitor with no DCR (dynamic contrast ratio) will not display the DCR option. In addition,
the wording of some options might vary slightly from the wording here, depending on model. These
variations are not great enough to cause confusion about which option is which.

Adjusting the Monitor Settings
You can use your computer software to set such parameters as sleep timer, resolution and color
temperature. Some monitor models provide for you to override the computer's settings with controls at
the monitor. Below are explanations of some of your options.
Using the HP Display Assistant Utility
HP Display Assistant, included on the software and documentation CD, is a software utility that guides
you through the tuning process with easy to understand instructions and background patterns designed
for each monitor control. Models ZR2040w, ZR2240w, and ZR2440w support the HP Display
Assistant.
The HP Display Assistant provides:
Accurate screen calibration through the use of step-by-step instruction Wizards to obtain the best
overall image quality.
●
Software control of the monitor image and color settings to eliminate dependence on the monitor's
front panel buttons and On-Screen Display (OSD) menu.
●
Defined preset display settings for each individual user in a multi-user environment.
Multiple preset display settings for a single user based on content and ambient lighting.
●
●
●
Asset Management and Power Management capabilities that include remote control for individual
displays or a group of displays on the domain from a centralized console application.
The HP Display Assistant Utility has two modes of operation: Wizard and OSD mode. The preferred
method of use is Wizard mode, which takes you through a step-by-step process to accurately calibrate
the monitor. This method relies on a sequence of steps that will give you the best display results.
NOTE: Refer to the HP Display Assistant user guide for additional information about the software.
Entering User Modes
A display mode is a combination of settings for resolution, horizontal frequency, and vertical
frequency. The monitor has preset modes from which it selects depending on the input it is receiving.
and recognize new modes if you change the settings yourself. The video controller signal may
occasionally call for this if you are not using a standard graphics adapter. To change resolution or
frequency, find the display settings provided by your computer's operating system.
Using the Auto-Adjustment Function
For models with analog input, you can optimize the screen performance for VGA by using the OK/auto
button on the monitor and the auto-adjustment pattern software utility on the CD provided.

Product Environmental Notices
ENERGY STAR® Qualification
As an ENERGY STAR Partner, Hewlett-Packard Company has followed the EPA’s enhanced product
qualification and certification process to ensure that the products marked with the ENERGY STAR logo
are ENERGY STAR qualified per the applicable ENERGY STAR guidelines for energy efficiency.
The following ENERGY STAR® certification mark appears on all ENERGY STAR qualified displays:
The ENERGY STAR® program specifications for displays and computers were created by the EPA to
promote energy efficiency and reduce air pollution through more energy-efficient equipment in homes,
offices, and factories. One way products achieve this goal is by using the Microsoft Windows power
management feature to reduce power consumption when the product is not in use.
The power management feature enables the computer to initiate a low-power or “sleep” mode after a
period of user inactivity. When used with an external ENERGY STAR® qualified display, this feature
also supports similar power management features for the display. To take advantage of these potential
energy savings, users should use the default power management settings that are provided with
ENERGY STAR qualified computers and displays. The default power management settings on ENERGY
STAR qualified computers are preset to behave in the following ways when the system is operating on
AC power:
Turn off an external display after 15 minutes of user inactivity
●
●
Initiate a low power sleep mode for the computer after 30 minutes of user inactivity
ENERGY STAR® qualified computers exit the low power sleep mode and ENERGY STAR qualified
displays resume operation when the user resumes use of the computer. Examples include the user
pressing the power/sleep button, receiving an input signal from an input device, receiving an input
signal from a network connection with the Wake On LAN (WOL) feature enabled, etc.
Additional information on the ENERGY STAR® program, its environmental benefits and the potential
energy and financial savings of the power management feature can be found on the EPA ENERGY

If a defective whole pixel is always turned off, it appears as a dark spot on a bright background.
A defective sub-pixel (dot defect) is less visible than a defective whole pixel and is small and only
visible on a specific background.
To locate defective pixels, the monitor should be viewed under normal operating conditions, in normal
operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm
(20 in).
The panel is 90% defect-free at the time of shipment. HP expects that, over time, the industry will
continue to improve its ability to produce LCDs with fewer cosmetic imperfections and HP will adjust
guidelines as improvements are made.
