Faithful Color Correction from the 3D-LUT

By using a three-dimensional LUT (Look Up Table) for each RGB 
color and applying precise 10 bit image processing, faithful colors 
are reproduced from low to high luminance levels and natural 
intermediate colors are attained. (See page 2 for details.)

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 to generate 
progressive signals without causing field-length delay. Minimizing the 
delay between the input signal and monitor output enables the user 
to confirm footage without any incongruity.

* 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.

Broadcast Settings for 

Gradation and Color Temperature

Individual RGB corrections are made on every monitor that is 
shipped, to ensure that rated gamma properties (g = 2.2) are 
reproduced, and gradation suitable for broadcasting is achieved. A 
color temperature of 9300 K/6500 K/5600 K, or 3000 K to 9300 K, 
can be selected with the variable setting.

WFM (Y/R/G/B) Display

The built-in waveform monitoring 
function displays a waveform in a 
sub-screen. The display signal can 
be selected from Y, R, G and B.

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.

Various Markers

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

• Aspect Marker (16:9):

 4:3, 13:9, 14:9, CNSCO2.39, CNSCO2.35, 

2:1 or VISTA, with background brightness control of Black (0%), Half 
(50%) or Normal (100%).

• Safe Area Marker (16:9/4:3):

 

95%, 93%, 90%, 88%, 80% or VAR 
(variable setting).

• Center Marker (16:9/4:3):

 ON/

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

Cross Hatch Overlay

A simple cross hatch overlay can be 
displayed to check the tilt of the 
camera. 

Pixel-to-Pixel Display

This function lets you display and 
confirm video pixels without any 
resizing. When displaying 1080i/p, 
you can choose from five display 
areas: center, right-top, right-
bottom, left-top or left-bottom.

Still Frame Display

A frame of video can easily be frozen 
and displayed as a still image on the 
left side of the screen. This function 
can be used to match a live camera 
with a frame of video shot at an 
earlier time or with a different 
camera.

Audio Level Meter

The color audio level meter displays 
the input level of embedded audio 
(SDI, HDMI*) or analog audio.* The 
display mode can be selected from 
2-channel, 4-channel, 8-channel or 
OFF. And it's equipped with 
reference point setting, peak hold 
and over-range display functions.

* For HDMI or analog audio input, the level meter 
displays only two channels.

Time Code Display

With HD SDI input, this function 
displays the value of the VITC, LTC 
or UB time code.

Closed Caption Display

The BT-LH1850 can display closed 
captions with an SDI or VIDEO input. 
It supports the EIA/CEA-708 HD SDI 
closed captioning standard (EIA/
CEA-608 SD-SDI closed captioning 
standard), and can display up to 
eight windows simultaneously.

HV Delay Display and Mono Mode

The HV Delay function that displays the video blanking period, and 
the Mono mode that switches the display to black-and-white, can be 
assigned to function keys for quick access.
