unplug the unit and have it checked by qualified
personnel before operating it any further.
• Do not drop or place heavy objects on the power cord.
If the power cord is damaged, turn off the power
immediately. It is dangerous to use the unit with a
damaged power cord.
• Unplug the unit from the wall outlet if it is not to be
used for several days or more.
• Disconnect the power cord from the AC outlet by
grasping the plug, not by pulling the cord.
• The socket-outlet shall be installed near the equipment
and shall be easily accessible.
• Do not use the 3D glasses as sunglasses.
• Do not use the 3D glasses as eye protection.
• Do not use the 3D glasses as welding glasses.
• Do not drive while wearing the 3D glasses.
• Take regular breaks between watching 3D video
images.
• Be careful not to pinch your fingers in the hinges of
the 3D glasses when moving the temple frames.
On Installation
• Allow adequate air circulation to prevent internal heat
build-up.
Do not place the unit on surfaces (rugs, blankets, etc.)
or near materials (curtains, draperies) that may block
the ventilation holes.
• Do not install the unit in a location near heat sources
such as radiators or air ducts, or in a place subject to
direct sunlight, excessive dust, mechanical vibration
or shock.
For LMD-4251TD
• To prevent injuries or accidents that might occur as a
result of the monitor falling over, be sure to use a
dedicated monitor stand when placing it on the table or
the floor. For details on the stand, please contact your
Sony dealer.
• Consult with Sony qualified personnel for installation.
Handling the LCD Screen
• The LCD panel fitted to this unit is manufactured with
high precision technology, giving a functioning pixel
ratio of at least 99.99%. Thus a very small proportion
of pixels may be “stuck”, either always off (black),
always on (red, green, or blue), or flashing. In
addition, over a long period of use, because of the
physical characteristics of the liquid crystal display,
such “stuck” pixels may appear spontaneously. These
problems are not a malfunction.
• Do not leave the LCD screen facing the sun as it can
damage the LCD screen. Take care when you place
the unit by a window.
• Do not push or scratch the LCD monitor’s screen. Do
not place a heavy object on the LCD monitor’s screen.
This may cause the screen to lose uniformity.
• If the unit is used in a cold place, horizontal lines or a
residual image may appear on the screen. This is not
a malfunction. When the monitor becomes warm, the
screen returns to normal.
• The screen and the cabinet become warm during
operation. This is not a malfunction.
On Burn-in
For LCD panel, permanent burn-in may occur if still
images are displayed in the same position on the screen
continuously, or repeatedly over extended periods.
Images that may cause burn-in
• Masked images with aspect ratios other than 16:9
(LMD-4251TD)
• Masked images with aspect ratios other than 16:10
(LMD-2451TD)
• Color bars or images that remain static for a long time
• Character or message displays that indicate settings or
the operating state
To reduce the risk of burn-in
• Turn off the character displays
Press the MENU button to turn off the character
displays. To turn off the character displays of the
connected equipment, operate the connected
equipment accordingly. For details, refer to the
operation manual of the connected equipment.
• Turn off the power when not in use
Turn off the power if the viewfinder is not to be used
for a prolonged period of time.
On a Long Period of Use
Due to the characteristics of LCD panel, displaying
static images for extended periods, or using the unit
repeatedly in a high temperature/high humidity

Precaution
6
environments may cause image smearing, burn-in, areas
of which brightness is permanently changed, lines, or a
decrease in overall brightness.
In particular, continued display of an image smaller than
the monitor screen, such as in a different aspect ratio,
may shorten the life of the unit.
Avoid displaying a still image for an extended period, or
using the unit repeatedly in a high temperature/high
humidity environment such an airtight room, or around
the outlet of an air conditioner.
To prevent any of the above issues, we recommend
reducing brightness slightly, and to turn off the power
whenever the unit is not in use.
Handling the 3D Glasses
• Do not touch the lens surface of the 3D glasses.
• Do not leave the 3D glasses in ambient high-
temperature, such as near heating equipment or inside
a car.
• Do not put extra pressure on the 3D glasses to avoid
them becoming misshapen.
• Make sure hard accessories or buckles not to touch the
lens surface of 3D glasses while holding or
transporting.
• Avoid wearing the 3D glasses when they are aging,
breaking or being damaged. Tiny scratches on the lens
surface may interfere with your viewing enjoyment.
Laying down or looking away from the screen will
lessen the 3D effect or shifts image colors.
About the Fluorescent Tube
A specially designed fluorescent tube is installed as the
lighting apparatus for this unit. If the LCD screen
becomes dark, unstable or does not turn on, consult your
Sony dealer.
On Cleaning
Before cleaning
Be sure to disconnect the AC power cord from the AC
outlet.
On cleaning the monitor screen and lens of 3D
glasses
While the monitor screen surface is especially treated to
reduce light reflections, the lenses of the 3D glasses are
also specially finished. As incorrect maintenance may
impair their performance, take care with respect to the
following:
• Wipe the screen and lens gently with a soft cloth such
as a cleaning cloth or glass cleaning cloth.
• Stubborn stains on the screen may be removed with a
soft cloth such as a cleaning cloth or glass cleaning
cloth lightly dampened with water. To remove
stubborn stains on the lens of the 3D glasses, rinse the
lens by hand with water and dry the lens gently with a
soft cloth.
• Never use solvent such as alcohol, benzene or thinner,
or acid, alkaline or abrasive detergent, or chemical
cleaning cloth, as they will damage the surface.
On cleaning the monitor cabinet and 3D
glasses frames
• Clean the cabinet and frames gently with a soft dry
cloth. Stubborn stains may be removed with a cloth
lightly dampened with mild detergent solution,
followed by wiping with a soft dry cloth.
• Use of alcohol, benzene, thinner or insecticide may
damage the finish of the cabinet and frames or remove
the indications on the cabinet. Do not use these
chemicals.
• If you rub on the cabinet and frames with a stained
cloth, they may be scratched.
• If the cabinet and frames are in contact with a rubber
or vinyl resin product for a long period of time, the
finish of them may deteriorate or the coating may
come off.
On Moisture Condensation
If the unit is brought directly from a cold place to a warm
place, or the unit is warm and the ambient temperature
cools suddenly (by air-conditioning, for example),
moisture may condense on the surface or inside of the
unit, or create a mist residue inside the protection plate.
This is called moisture condensation, and is not a
malfunction of the product itself, although it may cause
damage to the unit.
Leave the unit in a condensation free area.
If moisture condensation has occurred, turn off the unit
and do not use it until moisture condensation has
evaporated.
On Repacking
Do not throw away the carton and packing materials.
They make an ideal container which to transport the
unit.

stops and the RETURN button on the front panel blinks
for fan error indication, turn off the power and contact an
authorized Sony dealer.
Features
The LMD-4251TD (42-type) or LMD-2451TD (24-
type) is a multiple format LCD monitor equipped with a
circular micro-polarizer filter for broadcast use,
featuring a precise image and high performance. It
supports various 3D signal formats, including dual-
stream HD-SDI signals, by using an optional input
adaptor (BKM-250TG with a serial number 7400001 or
later) for both 2D and 3D signals. The provided two
pairs of 3D glasses are designed to suit the performance
of the monitor and for comfort over long hours of use.
The monitor has a number of new features for 3D picture
production, as well as various features supporting 2D
picture production.
Circular micro-polarizer filter
Two input signals are separated into even lines and odd
lines on the display and circular polarized before
appearing on the screen. Images on the left of the screen
are viewed through left lens of the 3D glasses and those
on the right are viewed through right lens. With this
feature, you can monitor multiple screens at one time.
Comfortable fitting lightweight 3D glasses
The provided 3D glasses are a lightweight design for
reduced fatigue after extended periods of use. The
glasses provide precise image quality and accurate color
reproduction. The frames are made of flexible material
and the lenses are encased in the top-center part of the
frames. This helps the glasses fit any face shape and
avoids distorting images through the lenses even when
adjusting the temple frames. Additionally, nose pad and
temple tips hold the glasses firmly under sweaty
conditions or physical working environment. Optional
3D glasses are available in two types; BKM-30G for
additional viewers and BKM-31G for eyeglasses users.
BKM-31G is lightweight, and includes flip-up lenses. It
can be directly attached to your eyeglasses.
Supporting various 3D input signal formats
With BKM-250TG (optional), various signals, such as
3G, dual-stream, side-by-side and line-by-line, are
supported. Install BKM-250TG with a serial number
7400001 or later to display HD-SDI signal in 3D. While
multiple signal formats–including 1080P, 1080i,
1080PsF and 720P–are available, line-by-line-type DVI
signals are also supported.
In addition, non-compressed horizontal resolution side-
by-side-type signals are supported. (Software versions
1.1 or later)
Select 720P scan size
NORMAL or NATIVE scan size can be selected when a
720P signal is input. (Software versions 1.1 or later, and
BKM-250TG with a serial number 7400001 or later)

in the text.

Features
8
Luminance difference display
Luminance difference between the left and right signals
is displayed. This function is convenient to check the
disparity. (Software versions 1.1 or later, and BKM-
250TG with a serial number 7400001 or later)
Checkerboard
Left and right HD-SDI input signals are displayed in a
grid pattern. The two signals shown in a grid makes for
easy adjusting of the iris and color settings for the
camera. This function is only available in 2D display
mode.
L/R switch
Left and right dual-stream HD-SDI signals can be
swapped over without being visually disturbed by black
frames. This allows you to easily compare the color and
brightness between left and right signals. This function
is only available in 2D display mode.
The automatic switch of left and right signals function is
supported. The switching interval can be selected from
among SHORT, MEDIUM and LONG. (Software
versions 1.1 or later, and BKM-250TG with a serial
number 7400001 or later)
White balance offset for 3D
You can set to match the white balance for 2D and 3D
images (with glasses). Also you can set to switch the
white balance automatically when selecting 2D or 3D
display. (Software versions 1.1 or later)
Grid display function
A grid (vertical and horizontal lines) can be displayed on
the entire screen. The vertical lines are used when
checking the overall image disparity. Both the vertical
and horizontal lines are used to check the geometrical
mismatch of left and right images. (Software versions
1.1 or later, and BKM-250TG with a serial number
7400001 or later)
Disparity ruler
Two vertical lines can be displayed for measuring the
disparity value of specific subjects. (Software versions
1.1 or later, and BKM-250TG with a serial number
7400001 or later)
Virtual subject marker
Use the virtual subject marker for planning the subject
position. A square marker is displayed as a pseudo-3D
subject marker. The position and screen depth of the
marker can be adjusted for planning the real subject’s
placement. The size of the square marker can also be
adjusted. (Software versions 1.1 or later, and BKM-
250TG with a serial number 7400001 or later)
Disparity simulation
The phase of either or both left and right signal for 3D
image can shift horizontally. The monitor simulates
parallax without the need for 3D rig adjustment. It saves
time and effort in setting and adjusting the 3D rig and
equipment.
Notes
• Going out of the disparity simulation feature
initializes the parallax setting. Adjust 3D rig if
parallax needs to be changed.
• Simulated images cannot be output to any device.
Horopter check
Left/right signals for the 3D image are displayed in
selected single colors. This helps you define if the
subjects are in front of the determined screen position or
behind it. You can carefully adjust the depth of the 3D
effect using this feature. This function is only available
in 3D display mode.
Flip H
If a half mirror type rig is used, left or right signal will
be reversed. With the Flip H feature, signals that are shot
this way are horizontally reversed again for normal
viewing.
Note
A delay between left and right signals occurs as a result
of the signal processing. Because left and right signals
are internally synchronized to offset the delay, display
speed may decrease before the image reaches the screen.
Payload ID
Channel assign information of payload ID data
superimposed on input signals is displayed. You can
monitor which of two channels a left/right input signal
is assigned to.
Dual time code display
The time codes for the both left and right signals are
displayed. When the time codes are out of sync, due to
incorrect VTR settings, etc., and the time code lag is
more than one frame, the time code on the right of the
screen is displayed with the black and white inverted.
(Software versions 1.1 or later, and BKM-250TG with a
serial number 7400001 or later)
High brightness LCD panel
Because of precise image, wide viewing angle
technology and high speed response, real color image
can be reproduced.
Multi-format
The monitor supports the video, Y/C, RGB, component,
SDI (3G/HD/SD, when the optional input adaptor is
used) signals and NTSC/PAL color systems.
