2 Safety and maintenance guidelines

Important safety information

A power cord is included with the display. If another cord is used, use only a power source and

connection appropriate for this display. For information on the correct power cord set to use with the

display, refer to the Product Notices document included on the media disc provided with the display.

WARNING! To reduce the risk of electric shock or damage to the equipment:

• Do not disable the power cord grounding feature. The grounding plug is an important safety feature.

• Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.

• Disconnect power from the product by unplugging the power cord from the electrical outlet.

For your safety, do not place anything on power cords or cables. Arrange them so that no one can

accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from the

electrical outlet, grasp the cord by the plug.

To reduce the risk of serious injury, read the Safety and 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 www.hp.com/ergo

and/or on the documentation disc, if one is included with the display.

CAUTION: For the protection of the display, as well as the media player/computer, connect all

power cords for the media player/computer and its peripheral devices (such as a display, 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 display.

WARNING! Displays that are inappropriately situated on dressers, bookcases, shelves, desks,

speakers, chests, or carts can fall over and cause personal injury.

Care should be taken to route all cords and cables connected to the display so that they cannot be

pulled, grabbed, or tripped over.

CAUTION: Do not place the device in a location where water may drip and/or splash on the

device.

Do not place an object that contains water, such as a flower vase, on the device.

Important safety information 3

Maintenance guidelines

To enhance the performance and extend the life of the display:

●Do not open the display cabinet or attempt to service this product yourself. Adjust only those

controls that are covered in the operating instructions. If the display 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 display, as indicated on the label/

back plate of the display.

●Be sure the total ampere rating of the products connected to the outlet does not exceed the current

rating of the electrical outlet, and 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 display near an outlet that you can easily reach. Disconnect the display by grasping the

plug firmly and pulling it from the outlet. Never disconnect the display by pulling the cord.

●Turn the display off when not in use. You can substantially increase the life expectancy of the

display by using a screen saver program and turning off the display when not in use.

CAUTION: Burn-in or image sticking might occur on displays which display the same static

image on the screen for prolonged periods of time. To avoid burn-in or image sticking and to

prolong the life of the display, you should activate one of the four ISM selections in the OSD,

activate a screen-saver application, periodically cycle between static information and moving

images, or turn off the display when it is not in use for prolonged periods of time.

●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.

●Do not drop the display or place it on an unstable surface.

●Do not allow anything to rest on the power cord. Do not walk on the cord.

●Keep the display in a well-ventilated area, away from excessive light, heat or moisture.

●When removing the display base, you must lay the display face down on a soft area to prevent it

from getting scratched, defaced, or broken.

Cleaning the display

1. Turn off the display and unplug the power cord from the back of the unit.

2. Dust the display by wiping the screen and the cabinet with a soft, clean antistatic cloth.

3. For more difficult situations such as removing fingerprints or other substances from the display

screen, use a foam window cleaner with no petroleum derivatives or alternatively use a 50/50

mix of water and isopropyl alcohol sprayed onto a cloth to clean the screen surface. Make sure to

protect against dripping any liquid under the bezel.

CAUTION: Never spray the cleaner directly on the screen surface. It might seep behind the bezel

and damage the electronics.

4 Chapter 2 Safety and maintenance guidelines

CAUTION: To clean the display screen or cabinet, do not use cleaners that contain any petroleum-

based materials such as benzene or thinner or any volatile substance. These chemicals might damage

the display.

Cleaning the protective glass overlay on select models

The protective glass is extremely easy to clean. Most marks wipe off with a dry cloth. Use a foam

window cleaner with no petroleum derivatives to remove more difficult substances. Avoid scrubbing

with any abrasive materials or scraping, as this can scratch the glass.

Shipping the display

Keep the original packing box in a storage area. You might need it later if you move or ship the

display.

Mounting a single display on a stand (Sold

Separately)

The stand kit is an optional accessory available from HP. It allows you to mount a single display in

landscape position. To mount the display on the stand:

1. Remove the four M4 x 32 mm (1.26 in) screws and stand from the box.

Figure 3-8 Stand accessory contents

2. Place a soft cloth on the table and place the display with the screen facing downward. Connect

the stand as shown in the following figure.

Figure 3-9 Securing the stand to the display

The long side of the foot should face forward when the screen is upright.

Installing the HP Frame System (Sold Separately)

The frame system creates a 10 mm border around one or more of the 47–in/119 cm displays, giving

the edge a finished look. To frame a group of displays, you need as many kits as you have displays in

a row or column, whichever is greater. For example, three kits will frame a 3 x 3 group, a 3 x 1 group,

or a 1 x 3 group.

The frame kit includes four rails, one each for top, bottom, left and right. It also contains four

interchangeable corner pieces and four interchangeable straight connectors.

12 Chapter 3 Setting up the display

The rails are labelled TOP for the top in landscape position, BOTTOM for the bottom in landscape

position, RIGHT for your right side as you face the front of the screen, and LEFT for your left side as

you face the front of the screen. All the screw holes match for the one rail that goes to each side; no

force is needed. Attempting to attach the wrong rail could damage the bezel.

When you frame a single array, the numbers on the rails match at each corner:

1 2

4 1

To frame a single display, attach the top rail to the top of the display with three of the large (M4 x 10

mm) screws provided. The rail overlaps the bezel of the display. Attach the bottom, left, and right rails

in the same manner, leaving the two small holes at each end open.

Figure 3-10 Attaching rails

Attach the four corner pieces with four small (M3 x 5 mm) screws each. These overlap the rails and

secure their ends.

Installing the HP Frame System (Sold Separately) 13

Figure 3-11 Attaching corners

Framing a group of displays is similar to framing a single display except that you will use some of the

straight connectors to cover the gap between adjacent displays.

Figure 3-12 Framing an array

Attach corners and straight connectors after the rails are in place.

Figure 3-13 Attaching corners and connectors

When you frame an array, the peripheral displays can no longer move independently. For this reason,

the following tasks may best be done before framing:

●Color Calibration

●Attaching all cables

●Putting the main power switch in the ON (|) position

●Horizontal, vertical and depth adjustment of all displays

14 Chapter 3 Setting up the display

Securing the display

Security cable provision—To help prevent theft, a security cable provision is available on the rear

of the display. The cable and lock required to connect to the display are available separately and can

be purchased from HP.

Figure 3-16 Power

Read the power-cord safety precautions in Important safety information on page 3, then plug the

other end into an electrical outlet.

Figure 3-17 Connecting the power cord

2. Put the master power switch (2) into the ON (|) position.

Figure 3-18 Turn On Power Switch

Connecting cables 17

3. If you will be using the VGA input for video, and you want to play the audio feed through the

external speakers, connect one end of an audio cable (sold separately) to the Audio input jack (3)

and the other end to the Line Out jack on the media player/computer.

NOTE: Before connecting to the AUDIO port on the display, verify what type of Audio Out

connection is available on the media player/computer sound card. The Line Out on a media

player/computer is used to connect to speakers, including a built-in amplifier (AMP). For

additional instructions, refer to the sound card manual.

If the Audio Out on the media player/computer sound card has only Speaker Out, reduce the

media player/computer volume before connecting to the AUDIO port on the display.

If the Audio Out on the media player/computer sound card supports both Speaker Out and Line

Out, choose Line Out.

Figure 3-19 Audio connection

NOTE: The ferrite core can be used to reduce electromagnetic waves when connecting an audio

cable. Fit the ferrite core to the audio cable. The ferrite core needs to be separated from the mold

by 5 cm (2 in).

Figure 3-20 Using the ferrite core

4. If you will be employing the HP external speakers, the bare speaker wire should be connected to

the matching color coded speaker connector for the Right and Left speaker, as in Connecting the

speakers (sold separately) on page 8.

Figure 3-21 External speaker connections

18 Chapter 3 Setting up the display

7. If you will be using analog video, plug the VGA cable into the VGA input connector (7). Since the

VGA connection does not transmit audio, you may need to connect an audio cable as described

in Step 1 (input is the lower of the two VGA connectors with the display on its face) and plug the

other end of the VGA cable into the VGA adaptor on the media player/computer.

If you will be connecting this display to another display via VGA (daisy chain), plug a one end of

a second VGA cable into the Output (upper) VGA connector (7) on the display and plug the other

end of the VGA cable into the Input (lower) VGA connector of the next display in the chain. (See

Connecting multiple displays to one player on page 24 for more details.)

Figure 3-24 VGA connection

Plug the free end of the VGA cable into a media player/computer or the previous display in a

chain of displays.

8. If you want to send video over the DisplayPort, connect the DisplayPort cable to the DP IN port on

the display (9) and connect the other end of the DisplayPort cable to the DisplayPort adaptor of

the media player/computer.

If you will be connecting this display to another display via DisplayPort (daisy chain), plug a one

end of a second DisplayPort cable into the DP-Out connector (10) on the display and plug the

other end of the DisplayPort cable into the DP-IN connector of the next display in the chain. (See

Connecting multiple displays to one player on page 24 for more details.)

Figure 3-25 DisplayPort

Connect the free end of the DisplayPort cable to the DisplayPort OUT port on the media player/

computer or previous display in a series.

NOTE: Since DisplayPort does not support RS-232 command data, you will also need to

connect either an RS-232 cable between the display and media player/computer or an Ethernet

connection to the network or media player/computer to use HP Network Sign Manager to

manage and control the display remotely.

20 Chapter 3 Setting up the display

9. If you will be connecting the display to a network, plug your CAT-5 network cable into the Ethernet

port (11).

Figure 3-26 Ethernet

The Ethernet cable from the display can connect to a media player/computer, a router (switch), or

an Intranet. A network connection enables the use of the Video Over Ethernet software to assign a

media player to drive the display. The connection also allows the HP Network Sign Manager

program, running on a networked media player/computer, to send command data.

Connect the Ethernet cable (not included) using one of the following connections:

●Computer Direct Connection—Connect the LAN cable to the LAN port on the display and to

the LAN port on the media player/computer (1).

●Router—Connect the LAN cable to the LAN port on the display and to a LAN port on the

router (2).

●Intranet—Connect the LAN cable to the LAN port on the display and to the Intranet network

via an access point (3).

Connecting cables 23

Connecting multiple displays to one player

Multiple displays may be connected to a single media player/computer two different ways, using

Video Over Ethernet or using Tile Mode with VGA or DisplayPort video inputs.

Connecting multiple displays with Video Over Ethernet (VOE)

To connect multiple displays to a single media player/computer, each display must be connected to the

same network as the media player/computer. The input source of each display must be set to VOE.

With VOE, displays are connected to media players/computer by establishing an Association between

the media player/computer and one or more displays on the network with the VOE software that runs

in the media player/computer. Up to 12 displays may be associated with a single media player/

computer (See the VOE Users Guide for more detail). When multiple displays are associated with a

single media player/computer, the displays may be mirrored (a single desktop image displays on all

the displays simultaneously).

Figure 3-30 Mirrored displays

The image may be extended across all the displays simultaneously using the View Span “Display

Resolution” dialog box.

Figure 3-31 Extended desktop

The displays may be treated by an application as 12 individual displaysthough there were up to

connected to 12 graphic adaptor heads on the media player/computer.

24 Chapter 3 Setting up the display

Figure 3-32 Multiple independent displays

The association of up to 12 displays is the technical limit, and depending upon the complexity of the

desktop image to be displayed (playing flash, or streaming video), the number of displays which can

be associated with acceptable video performance may be less than 12 (See the Video Over Ethernet

User Guide for more detail).

Connecting multiple displays to one player 25

Connecting multiple displays with Tile Mode

The recommended cable routing for daisy chain in Tile Mode is to start with the upper left display and

connect across the upper tier of displays going from left to right to the last display in that tier. Then

cable from the upper right display to the display just below it and connect across from right to left to the

last display on the left. Continue this back and forth, top to bottom cable route for all the tiers in the

wall as indicated in the next figure.

Figure 3-33 Recommended cable routing for Tile Mode

Multiple displays (up to 25) may be connected to a single media player/computer using Tile Mode.

Multiple displays in Tile Mode are only supported with either DisplayPort or VGA video input sources.

When connecting the multiple displays, the media player/computer is connected to the first display

only with either a DisplayPort or VGA connection to the media player/computer. All the subsequent

displays are connected to each other via daisy chain using either the DP OUT connector from one

display to the DP IN connector of the next display (Figure 3-35 Daisy chain connection – DisplayPort

on page 27), or using the VGA OUT connector from one display to the VGA IN connector of the next

display (Figure 3-36 27 Daisy chain connection -- VGA on page ). All displays must be connected

with the same video source, either DisplayPort or VGA. When using Tile mode to connect multiple

displays, only one desktop image may be displayed across all the tiled displays

To remotely manage and control multiple displays in Tile Mode when using either VGA or DisplayPort

video source, either a RS-232 or Network connection may be used with the HP Network Sign

Manager.

If using the RS-232 interface, the displays must be daisy chained with RS-232 cables. Attach one end

of a RS-232 cable to the RS-232 Input connector of the first display and connect to the serial connector

of the media player/computer. Then attach one end of an RS-232 cable to the RS-232 Output

connector and the other end to the RS-232 Input connector of the next display and continue to connect

the RS-232 cables between each display in the tiled matrix as shown in Figure 3-37 Daisy chain

connection – RS232-C on page 28.

Connecting multiple displays to one player 27

If using a Network connection, just attach each display to a network hub or access point using a CAT-5

cable, and HP Network Sign Manager will locate each network attached display. The HP Network

Sign Manager will allow users to select any display or assigned group of displays to manage and

control. If the display is already attached to the network for VOE, there is no further action required.

The HP Network Sign Manager will detect the displays via its search function (See the HP Network Sign

Manager Users Guide for more details).

Multiple displays may also be controlled and managed with the IR Remote Control. Since the primary

use of the displays is for video walls, use of the External IR Sensor is needed to provide the best IR

remote control responsiveness. Connect the supplied External IR Sensor to the IR IN (Blue) jack. Take

one end of the supplied IR Daisy Chain Cable and connect it to the IR OUT (Green) jack of the display

and connect the other end of the cable to the IR IN jack of the next display as shown in Figure 3-38

Daisy chain connection – External IR Sensor on page 28. Once all the displays are connected, the

user can issue any OSD command with the IR Remote Control to all the displays at once (for example,

turn the displays ON or OFF, set Picture Mode to VIVID, etc.), or the user can indicate a single display

in the wall to control by selecting the ID of the appropriate display and then issuing any OSD command

with the IR Remote Control. See Navigating with the infrared remote control on page 37 for more

detail.

Figure 3-38 Daisy chain connection – External IR Sensor

NOTE: The number of displays that can be connected by daisy chain to one media player/computer

might vary depending on the signal status and cable loss. If the signal status is good, and there is no

cable loss, it is possible to connect up to twenty-five displays in a daisy chain from one media player/

computer.

If you are going to play video that is copy protected with High-bandwidth Digital Content Protection

(HDCP), you must use DisplayPort as the video source, and you are limited to a maximum of six

displays in the daisy chain which can support HDCP.

When using Tile Mode, the display ID can be set in the display OSD with the IR Remote Control, the

display control panel, or for Network attached displays, the display ID can be set with the HP Network

28 Chapter 3 Setting up the display

Sign Manager software (See Using Tile Mode on page 49 and the HP Network Sign Manager User

Guide for more details).

After installing the cables, ensure that the power switch on all displays is in the on position (|). Turning

the Power Switch ON does not turn the display on. This is especially important if you will be mounting

the displays where access to the power switches is difficult.

Figure 3-39 Turn On Power Switch

The last step, after all the cables are connected and making sure the Power Switch is turned ON, is to

plug the AC power cord into a power source.

Mounting the display

The display can be mounted on a wall or a stand. If the mounting hardware permits, it can be mounted

in landscape or portrait orientation.

CAUTION: Always use the handles to lift the display, as the bezel is not meant to take its weight.

CAUTION: Two people are needed to safely mount the display.

This product supports a VESA FDMI (Video Electronics Standards Association Flat Display Mounting

Interface)-compliant mounting device. The mounting devices can be purchased separately from HP. Two

hole patterns are available, holes on 400 mm centers (1) and holes at 400 mm x 200 mm (2).

Mounting the display 29

Figure 3-40 VESA mounting holes

It is recommended that the 400 mm x 400 mm mounting pattern be used whenever possible.

The distances of each hole to the edges of the display are shown in Technical specifications

on page 63. The weight for your model can be found there as well; when mounting to a wall, ensure

that the supporting structure is strong enough for the listed weight.

30 Chapter 3 Setting up the display

Mounting in portrait position

When installing the display in the portrait position, rotate it clockwise based on its front. The display

can be rotated in only one direction. Arrows on the back of the display indicate which side should be

at the top in both portrait and landscape positions:

Figure 3-41 Up arrows

Figure 3-42 Installing portrait

The cable connectors will be on your left as you face the screen.

Considerations for wall mounting

When mounting displays in a video wall consider the following:

●If all the displays are on one electrical circuit, you can avoid overload at power up by using the

Power On Delay option in the OSD menu (Option 2 → Time → Power On Delay).

●Care should be taken to make sure that the displays are mounted so that they are just touching

and that there is no load bearing pressure between displays.

Mounting the display 31

4 Operating the display

The display can be operated with the infrared remote control, with the control panel buttons, or

remotely by any network connected media player/computer using HP Network Sign Manager. The

media player/computer running HP Network Sign Manager can be connected to the display directly

with an Ethernet peer to peer connection or RS-232-C serial connection, or remotely via an intranet

connection.

Operation with the remote or the control panel uses the On-Screen Display (OSD) menu. This chapter

details the menu.

The display provides for more than one source of video input. It will scan the various inputs to find an

active one and display that image. The default scan order is Video Over Ethernet, DisplayPort, VGA for

any inputs that are connected to a video source. Using the OSD menu, you can prevent the display

from switching inputs by disabling this function.

In order to send video over a network, you need to install the VOE software on the computer/media

player which serves as the source. See the Video Over Ethernet User Guide for details.

If the display is not receiving any input, it will go into low power mode (“sleep”). You can send it into

low-power mode using the power button on the back, the infrared remote control, or by scheduling

sleep times. Scheduling is done through the OSD or management software. You can also prevent the

display from sleeping.

Using the On-Screen Display menu

The on-screen display menu (OSD) lets you set a variety of parameters to control the display. Not all

settings are applicable to all video sources and these will be greyed out (unselectable) where they don't

apply. Auto Configuration, Clock Frequency, and Clock Phase apply only to VGA input.

Other settings store three values, one each for Video Over Ethernet, VGA and DisplayPort. These

settings are:

●Picture Mode

●Contrast

●Brightness

●Sharpness

●Backlight

34 Chapter 4 Operating the display

●Resolution

●Color Temperature

●Speaker

●Aspect Ratio

All other OSD settings need only be set once in order for the new value to apply regardless of the

video source.

You can operate the OSD using the infrared remote control or the control panel on the back of the

display.

Controlling displays with IR Daisy Chain

The display provides the capability of using IR Daisy Chain to enable selectable control of the displays

locally, using the IR Remote Control when the displays are mounted in a video wall. You may control

one display at a time by selecting the ID of the display, or you may control all the displays

simultaneously by selecting an ID of “00”.

Setting up IR Daisy Chain

The following describes how to set up the displays for IR Daisy Chain

1. Insert the External IR Sensor into the IR IN (blue) jack at the back of the display

2. Using the included IR Daisy Chain Cable, connect all the displays in the video wall. See

Connecting cables on page 15 for details.

3. Using the IR Remote Control or the display control buttons, go to MENU → OPTION 2 → SET

MONITOR ID and set the unique ID number (number between 1 and 25) for each display in the

video wall

4. Using the IR Remote Control or the display control buttons, go to MENU → OPTION 2 → IR OUT

and chose ENABLE for each of the displays in the video wall

5. Using the double sided tape, locate the External IR Sensor away in a spot where it will be easy to

point the IR Remote Control. It is recommended that the sensor be located at the top left or right of

the video wall.

NOTE: Care should be taken to avoid locating the sensor next to the bottom of any of the displays

where the IR sensor of the display could sense the IR Remote Control or where the sensor might block

the viewing area of any display.

Controlling displays with the IR remote control

Point the IR remote control at the External IR Sensor and press the MENU button. The IR Daisy Chain

home menu will appear on each display, with the Monitor ID displayed so you can easily identify the

36 Chapter 4 Operating the display

Press the SET button to select the display ID number as the display you want to send commands. The

LOCK message window will appear in all the other displays to indicate that they will not receive any

commands from the IR remote control through the External IR Sensor (Figure 4-3 IR Lock Message

on page 37). The On-Screen Display Menu will appear in the display selected. Any command, menu

selection, or setting entered with the IR remote control will now be executed by the selected display.

Figure 4-3 IR Lock Message

After a short period of time, the Lock message will disappear from the displays. At any time, you may

press the INFO button on the IR remote control and the Lock message will reappear on the displays not

selected to receive the IR commands:

Figure 4-4 Lock message from INFO command

Pressing the MENU key on the IR remote control will exit the IR daisy chain mode and unlock all the

displays.

Navigating with the infrared remote control

The IR sensor is on the back of the display but will receive IR signals coming from the front. Point the

remote control toward the bottom center of the screen. You can also use the external sensor provided,

which makes the remote control very easy to use. This is especially true for displays in a video wall. If

you have connected multiple displays with IR daisy chain, they will all respond to a key press of the

remote. See Controlling displays with IR Daisy Chain on page 35 for more details.

See Identifying remote control buttons on page 10 for details on IR remote control buttons and their

functions.

ceiling on the Backlight level. For example, if Energy Saving is set to Level 2 (60%), the Backlight scale

is effectively reduced to 0 to 60, since any setting above 60 will function as 60.

48 Chapter 4 Operating the display

Preventing and fixing ghost images

Displaying a static image on the screen for a long time can result in “burn-in” or image retention. To

avoid image retention, do not display a fixed image for long periods of time. Either turn the display off,

use one of the image retention choices (ISM) in the OSD, or change the image. You can help to avoid

or correct ghost images by using one of the ISM Method options:

1. Navigate to the Option 2 submenu and then to the ISM Method option.

2. Select one of the following menu options:

●Orbiter — The image will move two pixels every two minutes, alternately moving left, right,

up, and down. Orbiter will remain on until changed in the ISM Method menu.

●Inversion — This function can be used to fix a ghost or burned-in image. It will invert the

image colors every 30 minutes. The inversion function will remain on until changed in the

ISM Method menu.

●White wash — This function can also be used to fix a ghost or burned-in image. This

function will fill the screen with solid white. This helps to remove permanent images burned

into the screen. Pressing any key on the remote control will exit the White Wash function

and return the screen to Normal.

●Dot wash — Imposes a pattern of black dots on the image and moves them every 5

seconds.

●OFF — Choose if you do not want the ISM function to be active. When the display is turned

off, the ISM setting is lost and will be OFF when the display is next turned on.

Using Tile Mode

Tile Mode lets you define an array of up to 25 displays showing a single image. The array need not

have the same number of columns as rows, and the displays can be in landscape or portrait

orientation. Tile mode is designed for use with daisy chained displays receiving VGA or DisplayPort

input. If the input source is Video Over Ethernet, each display must be sent the same image for tile

mode to work. (See the Video Over Ethernet User Guide for details).

Video signal strength will determine how many displays may be daisy chained together. Degradation

of the video signal due to distance may limit the maximum number of displays to less than 25.

You can set up tiling through the OSD menu of each display in the array. That method is described

here. You can also use HP Network Sign Manager for the same purpose. See the HP Network Sign

Manager User Guide for details.

On each display, enter the OSD and navigate to the Tile submenu. Set H Monitors to the number of

columns in the array and V Monitors to the number of rows. Set H Position to the column number

Optimizing analog images

When using VGA as your video source, you can optimize the screen performance by using the Auto

Configuration option in the OSD and the Auto-adjustment Pattern Utility software on the disc provided.

(When the video source is one of the digital formats, the display adjusts itself and there is no user

intervention.)

The procedure can correct the following image quality conditions:

●Fuzzy or unclear focus

●Ghosting, streaking or shadowing effects

●Faint vertical bars

●Thin, horizontal scrolling lines

Although the process will work with any image, it works best with the image in the Auto-adjustment

Pattern Utility supplied on the disc that comes with the display.

To use the auto-adjustment feature:

1. Allow the display to warm up for 20 minutes before adjusting.

2. Insert the disc in the disc drive. The disc menu appears.

3. Select Open auto-adjustment software. The setup test pattern appears.

4. You can launch the display's auto configuration process in two ways: by pressing the down arrow

on the back of the display while the OSD menu is inactive, or by selecting the Auto

Optimizing analog images 51

Configuration choice in the Option 1 menu of the OSD. Either way, the display will adjust

itself.

If the result is not satisfactory, continue with the procedure.

5. Navigate to Clock Frequency under the Option 1 submenu of the OSD. Increase or decrease

the value to minimize any vertical bars or stripes visible on the screen background.

Figure 4-7 Adjust frequency

6. Navigate to Phase. Increase or decrease the value to minimize video flickering or blurring.

Figure 4-8 Adjust phase

NOTE: The frequency must be adjusted before the phase, since the phase setting is dependent

on the frequency setting.

7. If the monitor images become distorted, continue adjusting the values until the distortion

Tuning color

The HP DreamColor Calibration Solution (purchased separately) can be used to calibrate the displays

in a video wall to ensure that their output closely matches each other. This prevents visible differences in

the composite image due to variations in color temperature, luminance, or gamut (the range of colors)

among the displays. It can also be useful to calibrate displays that are not in a video wall but which

should match each other, as when they are in the same room.

The HP displays contain an internal color management engine and calibration processing hardware,

allowing calibration without the use of an external computer; the colorimeter contained in the HP

DreamColor Calibration Solution is all that is required.

Calibration is performed on each display in a video wall and can be done before or after the wall is

assembled. It may be easier to calibrate the displays prior to wall assembly because the colorimeter

must be connected to the USB port on the back of the display. Since you might want to recalibrate a

video wall after it has been installed, HP recommends using scissor mounts or some other type that

allows you to move each display out from the wall and access the USB port. For a permanent wall

installation, a rack-mount USB extender facilitates access to the USB ports.

52 Chapter 4 Operating the display

In preparing to calibrate a display or video wall, observe the following guidelines:

●Decide how bright you want the screen to be. During calibration, you will choose a target

luminance. This value incorporates both the brightness of the backlight and of the LCD at full

white. As with the brightness control of a conventional monitor, the most pleasing setting depends

on the environmental lighting.

The maximum luminance depends on the color temperature, because temperature is adjusted by

decreasing light of certain colors. If you choose 9300K as your target color temperature for

calibration, you will be offered a luminance range from 200-500 cd/m

. If you set color

temperature to 8000K, the offered range will be 200-450 cd/m

, and for color temperature

6500K it will be 200-400 cd/m

Total light output diminishes as a display ages. After one year of continuous use all day every

day, the total light output the display is expected to have dropped by approximately 10%. With

these considerations in mind, you will be able to choose a target luminance from the range

offered.

●Warm up the display for at least one hour. This is required because the colorimetry of the image is

not stable until the display has reached uniform operating temperature. Even when the effect of

warm-up is not apparent, it can impact the calibration results.

●Ensure that there is no bright light shining directly onto the screen. Light reflecting off the display

onto the measuring sensor of the colorimeter will result in an incorrect calibration. If necessary,

cover the display surface and colorimeter with a light-blocking cloth.

●Clean the screen. Refer to Cleaning the display on page 4 for specific instructions.

●Set Energy Saving, Picture mode, Contrast, Brightness, Sharpness, Backlight, and Ambient Light

Sensor to their default values. Decide on the desired settings for Dynamic Contrast, Color

Temperature and Local Dimming. Set these to the same value on every display in the video wall.

●When calibrating a video wall, use the same colorimeter for all displays in the wall. Otherwise,

variation between colorimeters can jeopardize uniformity of the results.

Tuning color 53

To calibrate the display, follow these steps:

1. Plug the colorimeter into the USB port.

Figure 4-9 Plugging in the colorimeter

2. Navigate to the Color Calibration menu of the OSD. Use the Color Calibration option to Enter

the calibration process.

3. The time since power-up will be shown. If the display has not yet warmed up for one hour, either

wait for the display to complete the warm up or exit calibration menu and return later. If at least

one hour has passed since the display was last powered on, proceed to the next step.

4. Choose the desired color temperature from the color temperature options provided. This setting

must be the same for all displays in a video wall.

The native color temperature of the display is 9300° Kelvin (“9300K”). You can choose between

6500K, 8000K and 9300K. A lower color temperature results in a warmer picture, which may be

more pleasing, depending on the environmental lighting in the area of the video wall. However, in

order to lower the color temperature, blue light output must be restricted, which will reduce the

maximum possible brightness.

After choosing a color temperature, click on Enter.

5. Choose the target luminance. The slider moves in increments of 10 cd/m

. Once you have set the

luminance, click on Enter to move to the next option.

NOTE: If the display cannot be calibrated to the target luminance, an error message will appear

indicating the luminance that could be achieved. Use that or a lower value as the target for the

video wall, to ensure equal light output across the wall.

54 Chapter 4 Operating the display

6. Open the colorimeter by rotating the ambient light filter away from the lens. Do this by pulling up

on the filter arm and then swinging it out of the way.

Figure 4-10 Rotating the filter

Tuning color 55

7. Hang the colorimeter over the top of the display and position it in the center of the target

displayed on-screen. To do this, drape the USB cable over the top of the display so that the

counterweight is in back and the colorimeter in front.

Figure 4-11 Positioning the colorimeter

56 Chapter 4 Operating the display

8. Adjust the position of the counterweight so that the colorimeter is properly positioned and

maintains its position when released. To adjust the position of the counterweight on the USB cable,

squeeze the release button and slide the weight.

Figure 4-12 Adjusting the counterweight

Alternatively, you can mount the colorimeter on a tripod and position it in front of the displayed

target. If you use a tripod, position the colorimeter as close as possible to the screen and ensure

that it is positioned perpendicular to the surface of the display.

9. Click on Enter to begin the calibration process. The display will now begin calibrating itself. If the

colorimeter is not connected to the USB port of the display, a “Device Connection Error” will

appear. Connect the device and Retry.

If the colorimeter is not correctly aligned, a “Diffuser Position Error” will appear. Position the

colorimeter perpendicular to the screen, with the lens (which was covered by the ambient light

filter) against the screen, in the target being displayed. Then Retry.

Otherwise, you will see a message that the display is calibrating.

10. If you are calibrating a video wall, repeat these steps for each display.

To achieve the color temperature and luminance you specify, the display and colorimeter interact to

display and measure a series of colors. Needed corrections are written into a look-up table which the

display uses in daily operation.

To gauge the success of this process, the devices set brightness and contrast to 50, adjust the backlight

to produce the target luminance, and measure the following parameters:

●Luminance

●Color Temperature

●Gamma

●R, G, and B Primaries in CIE X,Y color space.

If any of their targets for these can not be achieved, a “Color Calibration Fail” message will appear

listing those parameters from the list that could not be adjusted properly.

When the process is finished, you can view the results with the Result option in the Color Calibration

submenu. In addition to the parameters listed, you will also see the number of hours since calibration.

Following calibration, changes to settings that affect brightness or color may prompt a warning that lets

you know the displays may no longer be showing the target luminance and color temperature. To

preserve uniformity, make any such changes to all displays in the video wall. Also, leave the ambient

light sensor off.

Tuning color 57

Once a wall has been calibrated, the calibration should be valid for 9000 hours, which is equivalent to

one year of continuous use (no off time). If an individual display is replaced during that time, it may

only be necessary to calibrate the replacement display(s).
