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 Power cord set requirements on page 62. 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.
● 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.
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.
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.
Identifying display components The major components of the display and their functions are shown here.
Connecting the speakers (sold separately) 1. Mount the speakers onto the display. Figure 3-2 Mounting the speakers 2. Use the four Taptite D3 x 12 mm (0.47 in) screws to secure the speakers to the display. Figure 3-3 Securing the speakers to the display 3. After installing the speakers, connect to the SPEAKER input terminal by connecting the proper color match for the left and right speakers.

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.
1 3 4 2 1 2 4 3 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.
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.
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.
Label Function 1 AC-IN Receives the power cord. 2 AC SWITCH Turns off or on power to entire device, controller as well as screen. 3 LINE-IN For an audio cable connected to the Line Out on a media player or computer sound card. The plug should be a standard-sized, TRS-type with stereo capability. 4 SPEAKER-OUT Audio output for bare-wire speaker connection to external speakers (sold separately). 5 RS232-OUT, RS232–IN Serial port for control of the display.
2. Put the master power switch (2) into the ON (|) position. Figure 3-18 Turn On Power Switch 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.
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 5.
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.
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.
Figure 3-27 Connecting the Ethernet cable 1 2 3 10. If you want to use the external IR sensor, plug it into the IR-IN jack (12). The external sensor makes using the remote easier, especially with displays mounted in a video wall. Figure 3-28 Infrared sensor connection Place the IR sensor facing where you want the remote to be.
11. If you want to connect this display to another in an IR daisy chain, plug the included IR Daisy Chain cable into the IR-OUT jack (13). The free end will plug into the IR-IN of the next display in the chain. Figure 3-29 IR-OUT connection 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.
Figure 3-31 Extended desktop 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.
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 3-34 Multiple displays with tile mode Figure 3-35 Daisy chain connection – DisplayPort D isp lay I n D isp lay I n Display I n Display I n Display Out Display Out Display Out Display Out Figure 3-36 Daisy chain connection -- VGA 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 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.
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.
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.
● If access to the back of the display will be difficult, you can attach all cables to each display before installation on the wall mount and turn the main power switch ON (|) before placing the display flush against the wall. You can perform any desired color calibration before mounting, or you can install a USB extension cable in the USB port to facilitate color calibration in the future. ● If you will be installing the HP LD4730 Framing System, do so after all displays have been mounted and adjusted.
3. Select Install display driver software. 4. Follow the on-screen instructions. 5. Ensure that the proper resolution and refresh rates appear in the Windows Display control panel. NOTE: You might need to install the digitally signed display .INF and .ICM files manually from the CD in the event of an installation error. Refer to the Display Driver Readme file on the CD for instructions (in English only). Downloading from the Web To download the latest version of .INF and .
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.
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.
Menu Setting Function A Monitor ID ID number assigned to the display in the SET MONITOR ID Dialog B IR Daisy Chain Monitor ID Enter the ID number of the display you want to receive the IR commands or enter “00” to control all the displays simultaneously C Set Button Sets the display ID of the display you want to control and will lock out all the other displays from receiving the commands D Exit Button Exit the IR Daisy Chain dialog without setting the display ID to receive commands Enter the I

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.
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.
Original image Tiled with Natural Mode on, the red bar is hidden and the slope is displayed correctly. Tiled with Natural Mode off, all bars are visible and the slope is disjointed. 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.
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.
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.
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”).
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.
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.
