3D/LH Series

(BT-3DL2550/LH2550/LH1760/LH1710/LH910G)

Features and Functions of the 3D/LH Series

Faithful Color Reproduction

Meets Broadcasting Needs

The 3D/LH series features an image
processing engine. By using a
three-dimensional LUT (Look Up
Table) for each RGB color and
applying precise 10-bit image
processing, it achieves faithful color
reproduction from low to high
brightness levels in all video formats.

*SMPTE-C in North America.

I/P Conversion Circuit for Motion Response

A circuit delay time (not including panel delay) of approximately 5
msec*

is achieved by incorporating an I/P converter circuit that

converts SD and HD interlace signals with high precision and
generates a progressive signal without causing field-length delay.
Minimizing the delay between the input signal and monitor output
enables the user to confirm footage without any incongruity.

*1: Differs slightly depending on the signal format.

Diagonal Line Compensation

Jagged noise on diagonal lines in
moving images is a common problem.
These LCD monitors solve this by
detecting correlations in the diagonal
direction, resulting in smooth, precise
reproduction of moving images.

High-Speed Response

The biggest concern when receiving a
video feed is response time in the intermediate gradations. The
BT-LH1760 uses double-speed drive to achieve superb response
over the entire image, enabling a vivid image display without
blurring. The other models feature an overdrive circuit to improve
response in intermediate gradations.

Wide Viewing Angle

By using a high-intensity, high-contrast
LCD panel, a wide viewing angle is
achieved in all models. The BT-3DL2550*/
LH2550 have a 178° viewing angle and the
BT-LH1760/LH1710/LH910G have a 176°
viewing angle (horizontal and vertical
angles in both cases). Easy viewing is
ensured by reducing color changes due to
the viewing angle.

Ideal Gradation for Broadcast

Applications, and Selectable Color Temperature

In order to optimize the LCD monitor for professional broadcasting
applications, compensation is conducted for each monitor in 256
discrete RGB steps, rated gamma properties (g = 2.2) are
reproduced, and gradation suitable for broadcasting is achieved.
Color temperature of 9300 K/6500 K/5600 K; 3000 K to 9300 K can
be selected with the variable setting. In the case of the BT-LH910G,
the manual white
balance lets you
directly adjust gain
and bias for R, G
and B.

Various Markers

Various markers can be displayed in both 16:9 and 4:3 aspect
ratios.

• Aspect Marker (16:9):

The BT-LH910G has seven
modes of 4:3, 13:9, 14:9,
CNSCO 2.39, CNSCO 2.35, 2:1
and VISTA. Other models have
five modes of 4:3, 13:9, 14:9,
CNSCO and VISTA, with
background brightness control of
Black (0%), Half (50%) or Normal
(100%).

• Safe Area Marker (16:9/4:3):

95%, 93%, 90%, 88% or 80%.
In 16:9 mode, all models can
display a superimposed safe
area marker corresponding to
the aspect marker’s angle of
view.

• Center Marker (16:9/4:3): ON/

OFF. The center marker can be
displayed together with another
marker, as shown in the example
of right above.

Cross Hatch Overlay

A simple cross hatch overlay can
be displayed to check the tilt of
the camera. The BT-LH2550
displays the cross hatch overlay
at 120-dot intervals. The
BT-LH1760/LH1710 displays at
80-dot intervals. The BT-LH910G
displays at 40/80-dot intervals.
The BT-3DL2550 displays
vertical lines at intervals of 6% of the screen width.

Waveform Monitoring

The built-in waveform monitoring
function displays a waveform in a
sub-screen. In addition, the
BT-LH910G lets you select the
signal to be displayed from Y, R,
G or B.

* Not provided in the BT-3DL2550.

Vectorscope Display

All lines of the input signal via
SDI are displayed as a
vectorscope, and can be
positioned in any of the four
corners of the screen.

* Not provided in the BT-3DL2550.

Pixel-to-Pixel Display

This function lets you display and confirm video pixels without any
resizing.

• BT-LH1760/LH1710:

When

displaying 1080i/p, you can
check the zoom-in image and
choose from five display areas:
center, right-top, right-bottom,
left-top or left-bottom.

• BT-LH910G:

With 1080/60i

input signals, you can check the
zoom-in image with a screen
width equivalent to 342.9 mm
(13.5 inches).
