High Grade 3D LCD Monitor
optimum solution for 3D Monitoring applications
LMD-4251TD is a 42-inch widescreen LCD monitor designed to satisfy
the rapidly growing demand from 3D productions in the broadcast and
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
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, post-production 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
1920x1080 Full HD LCD Panel

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 images.
The LMD-4251TD adopts a 3D micro polarizer filter attached to the
LCD panel, and is supplied with circular-polarizer 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 circular-polarizer filter glass.
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 display feature – Horizontal
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
3D display feature – Disparity
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
display feature – Horopter Check
This function helps users to perceive the subtle difference of
depth between different objects placed on the 3D screen
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
3D display feature – L/R
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
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 temperatures of 9300k,6500k, or a user preset value can be
Accurate and Repeatable Colour
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
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
3G SDI Input
The LMD-4251TD has a 3G SDI input capability. On Sony's montiors,
the 3G SDI interface is compliant with the SMPTE 425 standard,
transmitting up to 4:2:2/10bit 1080/60P video data using one SDI
cable. 3D left and right signals can be handled through a single
HD-SDI cable with a 3Gbs data rate.
Multi-Format Signal Support - up to 3G SDI
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,
