Features
High-quality LCD panel which provides a wide variety of
contents and messages clearly
Full HD panel Page 58
The LDT462V 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 Configuration Suitable for
Diversified Applications
Tiling Capability with Frame compensation Page 52
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, 47, and 55
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.
Digital Zoom Page 45
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.
Option slot allowing installation of extension modules
according to applications
Option Slot Page 22
You can mount Intel®OPS-compliant extension modules on the
monitor. With an OPS-compliant extension module, you can extend
the functionality of the monitor according to the purpose of use.
SDI Connection (option) Page 22
The SDI BOX receives SD-SDI, HD-SDI, and 3G-SDI signals at
a maximum speed of 2.970 Gbit/s and displays them on the monitor.
A single image is distributed to multiple monitors that are
daisy-chained via SDI cables (BNC).
Variable Management Functions Supporting Efficient
Operation and Management
Programmable Scheduling Function
Pages 36, 37, and 50
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 48
To reduce image persistence and maximize the panel life in
demanding signage applications, this product is equipped with four
screen-saver functions.
• GAMMA
• COOLING FAN
• BRIGHTNESS
• MOTION
Power-on Delay Page 52
For installations employing numerous monitors, the power-
on 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.

P-1 Preparation for installation
This LCD has a temperature sensor and cooling fan. If the LCD
becomes hot, the cooling fan will turn on automatically. If the
LCD becomes overheated, the “Caution” menu will appear.
If the “Caution” menu appears, stop using the monitor and
allow it to cool. When the LCD monitor is used in an enclosure
or with protection on LCD surface, please check the inside
temperature of the monitor by “HEAT STATUS” (See page 52). If
the temperature is higher than the normal level, set “COOLING
FAN” to ON using the SCREEN SAVER function (See page 48).
When mounting an OPS-compliant computer (commercially
available), turn on the cooling fan.
To avoid the monitor from falling
When installing the monitor using the tabletop stands (option),
take measures to prevent the monitor from falling over in case
of an earthquake or other disaster to lessen the probability of
injury and damage resulting from the fall.
As shown in the figure, secure the monitor to a solid wall or
pillar using rope (commercially available) strong enough to bear
the weight of the monitor. [LDT462V: approximately 26.5 kg (with
the optional stands)]
When using screw hooks (commercially available), use ring
hooks, not C-hooks (with opening).
CAUTION:
• The effect of the fall prevention substantially depends
on the strength of brackets and base to which the fall
prevention devices is attached. When you cannot ensure
sufficient strength, provide adequate reinforcement.
• Though the recommended fall prevention is intended to
lessen the probability of injury and damage, it doesn’t
assure its effectiveness against any kind of earthquake or
disaster.
• Do not sleep where the monitor may topple over or fall in
case of an earthquake or other disaster.
• Before moving the monitor, remove the rope that is
securing the monitor. Failure to do so may result in injury or
breakdown of the monitor.
Determine the installation location
CAUTION:
DO NOT ATTEMPT TO INSTALL THE LCD MONITOR BY
YOURSELF.
Installing your LCD monitor must be done by a qualified
technician. Contact your dealer for more information.
CAUTION:
MOVING OR INSTALLING THE LCD MONITOR MUST BE
DONE BY TWO OR MORE PEOPLE.
Failure to follow this caution may result in injury if the LCD
monitor falls.
CAUTION:
Proper operation of the monitor is not guaranteed when it is
mounted upside down, face up, or face down.
IMPORTANT:
Lay the protective sheet, which was wrapped around the LCD
monitor when it was packaged, beneath the LCD monitor so as
not to scratch the panel.
Ventilation requirements for enclosure mounting
To allow heat to disperse, leave space around the monitor as
shown in the figure below.
CAUTION:
Don’t block the holes in the rear of the monitor shown in the
figure above. If they are blocked, heat accumulates inside the
monitor, causing breakdown. The upper limit of the operation-
guaranteed ambient temperature when the monitor is installed
in the landscape position is 40˚C. When installing the monitor
in a case or an enclosure, ensure adequate ventilation to keep
the temperature inside the case 40˚C or lower by providing
a cooling fan or ventilation holes in the case. The upper limit
when the monitor is in the portrait position is 35˚C.

Using the wall mount or ceiling mount
Lay the screen face down
Lay the protective sheet on a table, which was wrapped around
the monitor when it was packaged, beneath the screen surface
so as not to scratch the screen surface.
This device cannot be used or installed without the Tabletop
Stand or other mounting accessory. Failure to follow the correct
mounting procedures can result in damage to the equipment or
injury to the user or installer. Product warranty does not cover
damage caused by improper installation.
Failure to follow these recommendations can void your
warranty.
For installation, use M6 screws (with a loose-proof spring
washer and having a length 10 mm longer than the thickness of
the mounting bracket) and tighten them securely. MITSUBISHI
ELECTRIC recommends using mounting interface that comply
with TÜV-GS and UL1678 standard in North America.

CAUTION:
For preventing the monitor from falling.
• Install the monitor with metal brackets for wall or
ceiling installation (commercially available) on your own
responsibility. For detailed procedures of installation, refer
to the instructions of the metal brackets.
• To lessen the probability of injury and damage resulting
from fall of the monitor in case of earthquake or other
disaster, be sure to consult the bracket manufacturer for
installation location.
• To lessen the risk of falling of the monitor, thread
commercially available rope through the handles at the
right and left of the monitor and secure the rope to the
wall mount brackets or ceiling mount brackets. Use rope
that can bear a load 6 times the weight of the monitor
(approximately 150 kg).
• Do not sleep where the monitor may topple over or fall in
case of an earthquake or other disaster.
• Use screws having enough strength to support the LCD
display monitor (made of stainless steel etc.).
