Features
High-quality LCD panel which provides a wide variety of
contents and messages clearly
Full HD panel
Page 56
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.
Power-on Delay
Page 51
For installations employing numerous monitors, the poweron delay function can power up the monitors sequentially with
delay between 2-50 seconds after the power is applied. Using
this function can prevent inrush current problems and reduce
the overall electrical load requirements when a single power
supply is used.
Others
Enhanced Display Functionality for Various Commercial
Use/Support for System Configuration Suitable for
Diversified Applications
Digital Zoom
Page 44
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
Page 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
Pages 10, 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.
DisplayPort
Pages 9 and 19
DisplayPort-compliant terminal is provided.
The monitor is equipped with a terminal supporting DisplayPort,
the digital interface standard. You can transmit video signals
over a single cable of max. 15 meters long.
Built-in Speakers
Pages 8, 16, and 34
Speakers inside the display unit create stereo sounds and used
to communicate voice messages. External special optional
speakers can be connected, so that the built-in and external
speakers can be switched for use.
Remote Control
Pages 10 and 11
Special wireless remote control supports major operations and
settings.
The special wireless remote control is supplied for major
controls such as power-on/off, video source switching, and
various settings.
Closed Caption
Page 51
You can display captions.
When closed-caption video signals are input, you can select to
display or hide the captions on the screen.
This monitor is compliant with EIA-608-A.
USB hub function
Pages 9 and 26
Multiple USB devices can be connected to the computer.
The monitor is equipped with the USB hub having four selfpowered downstream ports, where the USB devices can be
connected.
Equipped with CAT5 Analog Signal Transmission Function/
Supports Max. 150-meter Cable
CAT5 Video Connection (option)
Page 22
Transmitting analog video signal and control signal over a
single CAT5 cable.
You can transmit analog RGB video signal and display control
signal over a single CAT5 cable up to 150 meters at the
maximum. Furthermore, you can connect up to 4 monitors in a
daisy-chain configuration using CAT5 cable (max. 200 meters).
Variable Management Functions Supporting Efficient
Operation and Management
Programmable Scheduling Function Pages 35, 36, and 49
The monitor’s operating schedule can be programmed for
up to seven different scheduled time intervals by time, day
of the week and input port. This allows video content from
different inputs to be displayed on certain monitors within the
same installation according to the schedule, and extends the
monitor’s life and saves the power by turning it off during those
hours or days it is not in use.
Screen-saver Functions
Page 47
To reduce image persistence and maximize the panel life in
demanding signage applications, this product is equipped with
four screen-saver functions.

Recommend Use
CAUTION:
• For optimum performance, allow 20 minutes for warm-up.
• Rest your eyes periodically by focusing on an object at least
5 feet away. Blink often.
• Position the monitor at a 90° angle to windows and other
light sources to minimize glare and reflections.
• Clean the LCD monitor surface with a lint-free, non-abrasive
cloth. Avoid using any cleaning solution or glass cleaner!
• Adjust the monitor’s brightness, contrast, and sharpness
controls to enhance readability.
• Avoid displaying fixed patterns on the monitor for long
periods of time to avoid image persistence (after image
effects).

Ergonomics
To realize the maximum ergonomic benefits, we recommend
the following:
• Use the preset Size and Position controls with standard
signals.
• Use the preset Color Setting.
• Use non-interlaced signals.
• Do not use primary color blue on a dark background, as
it is difficult to see and may produce eye fatigue due to
insufficient contrast.
