Cleaning the LD4730

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.

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 LD4730G

The protective glass on the LD4730G 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.

ENWW Maintenance guidelines 5

3 Setting up the display

The display offers multiple connections for video and audio input. Analog video is input through the VGA port, while digital video can be input through either Video Over Ethernet (VOE) or DisplayPort.

Sound can be transmitted with accompanying video through VOE or DisplayPort. To play sound accompanying VGA video, use the audio connection.

Control data, such as power-on or input-select, can be sent through the infrared remote control, an attached media player/computer via RS-232, a networked media player/computer via Ethernet (use the HP Network Sign Manager software), or using the control panel buttons on the back of the display.

The displays can be mounted on a stand or a wall. The stand allows good access to the control panel.

With wall mounting, you can control the display with the remote or through software running on a media player/computer. The HP Network Sign Manager is designed for this purpose.

Displays can be set up in a tiled array. See sensor is particularly helpful for displays mounted in an array. Displays can be connected by their IR ports with the IR daisy chain Cable and be controlled either as a group or singularly using the remote control (See

Unpacking

CAUTION: Always use the handles on the back of the display to lift or move it. Avoid holding on to

the bezel or frame.

Care must be taken to avoid breaking or scratching the glass surface of the LD4730G model display. Size and weight make it advisable for two people to unpack it together. When laying it flat, either lay it on its back or on a padded, flat surface. When handling the display, always use the four handles on the back of the display and avoid placing hands on the bezel or frame to lift or move 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 LD4730 Frame System (Sold Separately)

The frame system creates a 10 mm border around one or more LD4730 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.

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:

12 Chapter 3 Setting up the display ENWW

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.

Figure 3-11 Attaching corners

ENWW Installing the HP LD4730 Frame System (Sold Separately) 13

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:

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

The displays may be treated by an application as though there were up to 12 individual displays connected to 12 graphic adaptor heads on the media player/computer.

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

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 (

on page 25), or using the VGA OUT connector from one display to the VGA IN connector of the

next display ( 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 26.

ENWW Connecting multiple displays to one player 25

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

Network Sign Manager Users Guide

Multiple displays may also be controlled and managed with the IR Remote Control. Since the LD4730/LD4730G primary use 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 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

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 Sign Manager software (See

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).

Figure 3-40 VESA mounting holes

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

ENWW Mounting the display 27

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

on page 55. 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.

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:

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

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.

Controlling displays with IR Daisy Chain

The LD4730/LD4730G 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 display you want to issue the command to (

Power On Delay

Power on delay lets you stagger the initial current draw of multiple displays on one electrical circuit. Each display will compute its own delay time. If its V Monitors setting in the Tiling submenu is 1, the delay will be a random number between 0.5 and 2.5 seconds. If V Monitors is anything else, its delay will be (0.5 * V Position) seconds.

Using Key Lock

The buttons on the back of the panel can be disabled to prevent accidental changing of the settings. To do this, press the left and right arrows buttons simultaneously and hold for 5 seconds. The same procedure will enable the buttons again. If the buttons are not accessible, use the infrared remote control to enter the OSD menu, navigate to the Option 2 submenu, and turn the Key Lock option off or on.

Setting the backlight level

The OSD offers two setting which change the backlight level. The Backlight setting is a scale from 0 to 100. The Energy Saving setting is a choice of four levels, given as percents. Energy Saving imposes a 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.

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).

44 Chapter 4 Operating the display ENWW

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

Manager User Guide

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 for this display, counting from left to right. Set V Position to the row number, counting from top to bottom.

Each display in the tile mode array will receive the full image, but will display only its assigned part of the image based on its H Position and V Position.

Natural Mode allows the image to retain proportionality across the array by compensating for the width of the mullion (the distance between the active display area to the active display area of the adjacent display in the array). Set Natural Mode on or off, using the same setting for every display in the array.

If Natural Mode is off, the display shows the its entire portion of its assigned position within the active viewing area. If Natural Mode is on, each display will compensate for the mullion between the displays by eliminating that portion of its assigned image which would overlap the bezel. This results in a small part of the composite picture being invisible, as though blocked by the mullions between window panes.

Choose Natural Mode on if you want the composite to be correctly proportioned and off if you want every pixel visible. The difference can be seen in the following:

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 CD 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 CD that comes with the display.

To use the auto-adjustment feature:

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

all bars are visible and the slope is disjointed.

2. Insert the CD in the disc drive. The CD 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 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.

Tuning color

The HP DreamColor Display 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 LD4730 and LD4730G 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 Display 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.

ENWW Tuning color 47

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 temperature to 8000K, the offered range will be 200-450 cd/m it will be 200-400 cd/m

, and for color temperature 6500K

. If you set color

Total light output diminishes as a display ages. After one year of continuous use all day every day, the total light output an LD4730 or LD4730G 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

●

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

●

Cleaning the LD4730 on page 5 for specific instructions.

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.

To calibrate the display, follow these steps:

1. Plug the colorimeter into the USB port.

Figure 4-9 Plugging in the colorimeter

R+L

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

the calibration process.

48 Chapter 4 Operating the display ENWW

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.

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.

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

ENWW Tuning color 49

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

50 Chapter 4 Operating the display ENWW

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.

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).
