High-quality LCD panel which provides a wide variety of contents and messages clearly

Full HD panel

The LDT551V panel reproduces images from video and computer signals with precision and clarity, delivering full 1920 x 1080 high-definition resolution. The high-durability panel reduces the risk of image persistence in commercial applications.

Enhanced Display Functionality for Various Commercial Use/Support for System Confi guration Suitable for Diversifi ed Applications

Digital Zoom

Zoom mode for expanding 4:3 image to 16:9.

Various zoom modes are provided and it is possible to expand 4:3 aspect ratio images to 16:9. In addition, you can select the dynamic display mode to display naturally widened images with different zooming rates around the screen center and screen edges. You can also optimally change the image size diagonally, horizontally, and vertically.

Tiling Capability with Frame compensation

50

Up to 25 panels (5 wide x 5 high) can be combined to create a single large image (i.e., video wall) or other high-impact signage. A frame compensation function is incorporated to compensate the width of panel bezels so that images are displayed with the utmost accuracy.

PiP, PoP and Side-by-side

46, and 53

Picture-in-Picture and Picture-out-of-Picture are available when you want to display video content from a video input source in the sub picture and display the PC input source in the main picture, and vice versa.

The native resolution as high as 1920 x 1080 can display these two input sources in the Side-by-side mode, ideal for broadcasting and video-conferencing applications.

RS-232C/RS-485 Remote control

When the monitor is connected directly to a computer using an RS-232C cable (commercially available), the following operations can be controlled via a communication. When the monitor is connected with a computer using an optional CAT5 Kit (option), the CAT5 Tx BOX is connected to the CAT5 Rx BOX through RS-485, which makes longer-distance remote control possible. When the CAT5 Tx BOX is connected using a USB cable, it functions as an RS-232C (COM) port by a Windows driver.

  • Power ON or OFF
  • Switching between input signals
    • Volume control and mute
  • Auto setup
  • Check of the internal temperature of the monitor, etc.

CAUTION:

Never connect network devices to the CAT5 IN and OUT connectors. If you do so, they may adversely affect with each other, causing breakdown.

NOTE:

For connection with a 25-pin serial port connector on the computer, a conversion adapter (commercially available) is required.

1) Interface

PROTOCOL RS-232C/RS485 (CAT5)
BAUD RATE 9600 [bps]
DATA LENGTH 8 [bit]
PARITY BIT NONE
STOP BIT 1 [bit]
FLOW CONTROL NONE
  • For direct connection using RS-232C, use the RXD, TXD, and GND lines.
  • For connection of the CAT5 Tx BOX using RS-485, either of the two communication modes can be selected by the COM. MODE switch.

LEGACY: The RXD, TXD, RTS, DTR, and GND lines are used. For a control program, RTS and DTR as transmit control signals of negative logic are used. The transmission period of TXD and the hold time of 70 ms are defined as “Sending (Low),” and the subsequent processes as “Receiving (High).”

AUTO: The RXD, TXD, and GND lines are used. A response from the monitor will be returned in 70 ms or later.

2) Control command diagram

The command is structured by the address code, function code, data code and end code. The length of the command is different for each function.

NOTE:

  • This example shows a basic command that is used when a single computer and a single monitor are connected. When you want to connect multiple monitors or perform complicated control using other commands than the basic commands, contact your dealer for advanced command specifications.
  • To send commands with a keypad using terminal software, select "2s" or "30s" for CONTROL TIME OUT in CONFIGURATION2 in the OSD menu. (Follow the same procedure for LAN control.)
Address codeFunction codeData codeEnd code
HEX30h 30hFunctionData0Dh

[Address code] 30h 30h (ASCII code, '0' '0'), fixed.
[Function code] Code unique to each control function.
[Data code] Data unique to each control function (Not always indicated by numerical values.)
[End code] 0Dh (In ASCII code, ‘☐’) fixed.

3) Control sequence

(1) A command is sent from the computer to the monitor. (Commands should be sent at intervals of at least 600 ms.)
(2) The monitor sends a return command within 600 ms* after receiving and encoding the command. If the monitor fails to receive the command, it doesn't send any return command.
(3) The computer checks the return command to see that the command it sent was executed or not.
(4) The monitor sends various codes other than the return code. While RS-232C control sequence is in progress, reject other codes on the personal computer side.

*: Transmission of the return command may be delayed during signal switchover, etc.

Example: Turn the power ON (‘ ’ is for ASCII code)

  • When you send the POWER ON or POWER OFF command, send the next command at intervals of at least 14 seconds.
  • When you send each INPUT switch command, send the next command at intervals of at least five seconds.
  • In the power off mode or the sleep mode, only the POWER ON, POWER OFF, and POWER ON read command which is described on the next page can be operated.
    * OPTION can be used when an optional module is mounted on the option slot.

5) Read command

The computer sends the command without datacode to the monitor.

After receiving this command, the monitor returns the command with datacode including the current status to the computer.

Example: When the computer asks the power status of the monitor, and the status of the monitor is powered-on.

Remote control numbering function

By connecting multiple LDT551V monitors using RS-232C cables, you can control any one monitor or all the monitors by one remote controller.

  1. Assign arbitrary ID number to each of multi-connected LDT551V monitors using MONITOR ID.

ID numbers 1 to 26 are selectable.

It is recommended to assign sequential ID numbers from 1 and up.

  1. The remote control mode of the first LDT551V monitor is set to PRIMARY and those of the other monitors are set to SECONDARY.
  2. When you direct the remote controller at the remote control signal sensor of the PRIMARY monitor and press the DISPLAY button on the remote controller, the ID selection OSD appears at the upper left of the screen.

MITSUBISHI LDT551V - Remote control numbering function - 1

ID number of the currently viewed monitor

Select the ID number of the monitor you want to control using the +/- button on the remote controller.

The ID of the monitor you want to control is displayed at the upper left of its screen.

By selecting ALL, you can control all the multi-connected monitors.

  1. Direct the remote controller at the remote control signal sensor of the PRIMARY monitor.

OSD appears on the monitor having the ID number you selected.

NOTE:

When the ID selection OSD is being displayed on the PRIMARY monitor, press the DISPLAY button on the remote controller again to cancel the ID selection OSD and then control the monitor you selected.

If you set the remote control mode wrongly and remote control operation becomes unavailable, press any button on the control panel of the monitor to display the OSD screen and change the remote control mode using ADVANCED OPTION. By pressing and holding down the DISPLAY button on the remote control for 5 seconds or longer, the remote control mode is initialized to NORMAL.

No picture

  • The signal cable should be securely connected to the display card/computer.
  • The display card should be securely seated in its slot.
  • The Main Power Switch and the computer power switch should be in the ON position.
  • Make sure that the correct mode has been selected on the display card or system being used.
    (Please consult the display card or system manual to change the graphics mode.)
  • Check the monitor and your display card with respect to the compatibility and recommended settings.
  • Check the signal cable connectors for bent or pushed-in pins.

Power button does not respond

- Unplug the power cord of the monitor from the AC outlet to turn off and reset the monitor.

Image persistence

- Please be aware that LCD Technology may experience a phenomenon known as “image persistence.” Image persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but constant images being displayed for a long period of time should be avoided. To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an image was on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image.

NOTE:

As with all display devices, MITSUBISHI ELECTRIC recommends displaying moving images and using a moving screen saver at regular intervals whenever the screen is idle or turning off the monitor when not in use.

Image is unstable, unfocused or swimming is apparent

  • Signal cable should be securely attached to the computer.
  • Use the OSD Image Adjust controls to focus and adjust the display by increasing or decreasing the fine adjustment.
    When the display mode is changed, the OSD Image Adjust settings may need to be re-adjusted.
  • Check the monitor and your display card with respect to the compatibility and recommended signal timings.
  • If the displayed text is garbled, change the video mode to the non-interlace mode and use 60 Hz refresh rate.

Image of component signal is greenish

- Check to see if the DVD/HD input connector is selected.

LED on the monitor is not lit (No green or red color can be seen)

  • Power Switch should be in the ON position and power cord should be connected.
  • Make certain the computer is not in the power-saving mode (touch the keyboard or mouse).

RED LED on the monitor is blinking

- A certain failure may have occurred. Please contact your nearest authorized MITSUBISHI ELECTRIC service facility.

Displayed image is not sized properly

  • Use the OSD Image Adjust controls to increase or decrease the coarse adjustment.
  • Make sure that the correct mode has been selected on the display card or system being used.
    (Please consult the display card or system manual to change the graphics mode.)

Selected resolution is not displayed properly

- Use OSD Display Mode to enter Information menu and check that the appropriate resolution has been selected. If not, select corresponding option.

No sound

  • Check to see if the speaker cable is properly connected.
  • Check to see if the mute is activated.
  • Check to see if the volume is set to the minimum level.

Wireless remote control is not available

  • Check the wireless remote control's batteries status.
  • Check if the batteries are inserted correctly.
  • Check if the wireless remote control is pointing at the monitor's remote sensor.

"SCHEDULE"/"OFF TIMER" function is not working properly

  • The "SCHEDULE" function will be disabled when the "OFF TIMER" is set.
  • If the “OFF TIMER” function is enabled and the power to the LCD monitor is turned off if the power supply is interrupted unexpectedly, then the “OFF TIMER” will be reset.

Either light vertical or horizontal stripes may appear, depending on the specific display pattern. This is no product fault or degradation.
