42-inch 3D high grade LCD monitor
The optimum solution for 3D Monitoring
The LMD-4251TD is a 42-inch widescreen LCD monitor designed to satisfy the rapidly growing demand
from 3D productions in the broadcast and professional
This professional monitor incorporates a micro-polarizer filter attached to the LCD panel, and is supplied
with circular polarizer 3D glasses. Wearing these
lightweight 3D glasses, users can enjoy smooth, uninterrupted viewing of multiple monitors.
The LMD-4251TD inherits the proven technology and
features of the widely respected 2D LCD monitor, the
high grade LMD-4250W. The LMD-4251TD can also
display 2D pictures.
Key features of this monitor are Sony’s highly acclaimed, unique ChromaTRU colour matching technology and a Full-HD (1920 x 1080) resolution professional LCD panel with an excellent wide viewing
angle. Full digital 10-bit processing adds to the
already impressive array of specifications, delivering
smooth greyscale and colour transitions.
The LMD-4251TD can accept various source of 3D signal format such as 3D on 3G, Dual stream left and
right, Field sequential and side-by-side HD-SDI as
well as DVI-D line interleave (line by line) mode. A
new set of 3D features have also been added to the
monitor to help the user to manage the 3D effects
with efficiency. The BKM-250TG board is required to
display these features.
Entirely at home in broadcast, OB, production, postproduction and corporate environments, the
LMD-4251TD accepts a wide variety of PC and analogue video formats and optional decoder boards are
available for Standard and High Definition digital
video display.
All LMD Monitors come supplied with a 2-year
PrimeSupport contract which offers unique extra services and benefits for added peace of mind.
This product comes with the full PrimeSupport package. That’s fast, hassle-free repairs, a helpline
offering expert technical advice, and a free loan unit
while yours is repaired. Plus the peace of mind that
Sony is looking after your equipment – and your
High Definition 1920x1080 Full HD LCD Panel
Delivers outstandingly crisp, high brightness and high
contrast images.
High Purity Colour Filters
The LMD-4251TD uses precisely manufactured RGB
colour filters, allowing the reproduction of colours with
stunning depth and saturation to create highly natural
3D Circular-polarizer System
The LMD-4251TD adopts a 3D micro polarizer filter attached to the LCD panel, and is supplied with circularpolarizer glasses. In this system, the right and left
signals are sorted into odd lines and even lines respectively. The right and left images delivered from
the LCD panel are circular polarized in different directions through the micro-polarizer filter and the patterned retarder. Each right and left image can then be
viewed by the corresponding right and left circularpolarizer filter glass.
Unique Lightweight Circular-polarizer 3D Glasses
Sony BKM-30G circular-polarizer glasses are designed
for the 3D production operator’s convenience, and optimized for both LMD 3D monitors.
3D display feature – Horizontal Flip
When a half-mirror type of rig is used, either the left
or right signal may be reversed horizontally. The Flip
H function turns the reversed image to the normal
view. This is helpful because the user can refer directly to the rig camera, achieving a simple and costsaving system.
3D display feature – Disparity Simulation
Either the left or right signal phase (or both phases)
of a 3D image can be shifted horizontally. In this way,
users can simulate the amount of 3D image parallax,
and can judge whether the camera rig should be
adjusted on location or whether it would be better to
adjust the parallax later during the post-production
3D left and right signals can be handled through a
single HD-SDI cable with a 3Gbs data rate.
3D display feature – Horopter Check
LMD-4251TD can accept almost any SD or HD video
format, both analogue and digital. Includes NTSC,
PAL, component, RGB, Y/C, 480/60i, 575/50i, 480/
60p, 576/50p, 1080/50i, 1080/60i, 1080/50p, 1080/
60p, 720/50p, 720/60p, 1080/24psf, 1080/25psf,
1080/24p, 1080/25p, 1080/30p and PC signals from
VGA to Full-HD.
This function helps users to perceive the subtle difference of depth between different objects placed on the
3D screen surface.
3D display feature – Checker Board
Left and right input signals are displayed in a grid pattern on screen – divided into 9 blocks vertically and
16 blocks horizontally. By comparing adjacent images, users can recognise a difference in brightness
and colour setting of the left and right images, and
thus easily adjust the camera’s white balance and iris
3D display feature – L/R Switch
Left and right signals can be swapped in a moment
without inserting black frames, simply by manually
pushing a function key. This instant-swap capability
enables users to compare whole images and check for
any sense of incongruity or for unnatural images.
3D display feature – Payload ID Display
Channel-assign information about the payload ID data
of input signals is displayed on the menu screen. This
tells users how the left and right channels are assigned in the menu.
Colour Temperature
Colour temperatures of 9300k,6500k, or a user preset
value can be selected.
Accurate and Repeatable Colour Reproduction
ChromaTRU technology ensures close CRT colour accuracy and gamma matching throughout the product’s
life and delivers consistent colour temperature across
the entire greyscale range. Both control characteristics also assure extremely tight colour matching
between different model samples. Three settings are
available to simulate EBU, SMPTE and ITU-709 colour
White Balance Calibration Function
The LMD-4251TD employs software based white balance calibration function, which is called
LMD_AutoWhiteBalance. Combined with a PC and
commercially available calibration tool - X-Rite i1Pro this function enables precise and quick adjustment of
the monitor’s white balance.
10-bit Picture Processing
Delivers smooth colour and greyscale transitions for
high quality video production.
3G SDI Input
The LMD-4251TD has a 3G SDI input capability. On
