Contents

This product has been specially designed for commercial use. As such, it should be used and operated
only by persons with related expertise.

¥ The liquid crystal parts are fabricated using high-precision technology. The screen has effective pixels that cover

more than 99.99% of its area, but pixels may be missing or remain permanently lighted (red, blue and/or green) in
less than 0.01% of the area. This is not indicative of malfunctioning.

¥ The panel which protects the liquid crystal display has been specially treated.

Do not wipe it with hard cloths or rub it heavily as this will damage the surface of the panel.

¥ If a still image is displayed continuously for a long period of time, the image may be burnt onto the screen for

some time. (The shadow of the image will usually disappear after moving images are displayed for while.)

¥ The response speed and brightness of the liquid crystals will vary with the surrounding temperature.

Introduction

Designed for use in broadcasting and commercial applications, the model BT-LH900P is a slim-line and lightweight liquid
crystal video monitor with an 8.4-type liquid crystal screen.
For use, secure it in place by, for instance, installing it in a rack by using the optional rack-mounting adaptors BT-MA900G or
mounting it on a tripod. (For details, refer to the instructions in the operation guide of the BT-MA900G.)

∫ Slim design, light weight, compact size, low

power consumption and driven by DC
power

Since this monitor uses an LCD panel, it has a slim
design, light weight and compact size. Furthermore,
while supporting HD specifications, it has a low power
consumption, and it can be operated using DC power:
these are all features which make the monitor useful in
outdoor locations.

∫ Multiple formats supported

In addition to its two lines of SDI input connectors
(automatic HD/SD switching), the monitor provides one
line each of component input connectors and composite
input connectors.

∫ Wide viewing angle

The monitor can display excellent images over an angle
extending for 170 degrees in both the top-bottom and left­right directions.

∫ High-definition images

At 1024 a 768 dots (XGA), the large number of screen
pixels ensures a high color reproducibility and tonal
range.

∫ Functions

The main controls can be relocated to the bottom surface
or right panel of the main unit to support monitor
specifications, viewfinder specifications and other
applications.

≥ The monitor comes with a film gamma correction

function to support its use as the viewfinder for the AJ­HDC27F. (For further details, consult with your dealer
or a Panasonic Service Center.)

≥ Waveform monitor functions provided
≥ Marker functions and blue-only function incorporated
≥ RS-232C external control, remote control using GPI

connector enabled

BLUE/WWbutton

This button is used to move the cursor or change
settings while a menu is displayed.
If there is no menu display, it turns the blue-only
function ON or OFF. When this function is set to ON,
only the blue components among the RGB
components are displayed.

Tally lamps

In the above illustration, the R (red) tally lamp is shown
on the left and the G (green) lamp appears on the right.
These tally lamps can be lighted by initiating the GPI
ON/OFF operation.

<Note>

When the monitor is used outdoors, it may be hard to
see that the tally lamps are in fact lighted.

Function buttons

1

INPUT button

This button is used to select the signal input. Each
time it is pressed, the input channels are switched by
one setting in the following sequence: SDI 1 > SDI 2
> VIDEO > YPBPR/RGB.
By means of the INPUT menu settings, the unused
channels can be skipped.

2

MENU/EXIT button

This button is used to display the menus. When it is
pressed while a menu is already displayed, the menu
display is cleared or the menu at one hierarchical level
above is restored.
When the button is pressed while a setting is being
changed, the setting established prior to the change is
restored, and the menu at one hierarchical level
above is restored.

3

HD ZOOM/XXbutton

This button is used to move the cursor or change
settings while a menu is displayed.
If there is no menu display, it turns the HD ZOOM
function ON or OFF. When the button is pressed,
both the left and right sides of the images with a 16:9
aspect ratio produced by HD signals are cut off, and
images with a 4:3 aspect ratio are displayed on the
entire screen. When it is pressed, the original images
are restored.
The HD zoom function does not work when images of
SD signals are displayed.

Image controls

These controls are used to adjust the peaking/color
phase, chroma, brightness and contrast. When a control
is pushed in, it pops out to enable adjustment. When a
numerical value is changed from the default setting, the
lamp to the left of the control lights.
The adjustments performed using these controls are
valid only when the controls are in the "out" position, and
when a control is pushed back in, the value adjusted by
that control is returned to its default setting.

1

PEAK/PHASE (PEAKING/PHASE)

This control is used to adjust the peaking or phase.
Which of these is to be adjusted is set using the
PEAKING/PHASE item on the SYSTEM CONFIG
screen.

≥ PEAKING
This function is selected when the monitor is to be
used as a viewfinder.
It is used to set the edge sharpness. Any value
from 0 to 30 can be set: the higher the value, the
sharper the edges. The default setting is 0.
≥ PHASE
This function is selected when the monitor is to be
used as a monitor.
It is used to set the color phase of the screen. Any
value from 0 to 60 can be set. The default setting
is 30.

<Notes>

≥ When the blue-only function is ON, the control

functions as the PHASE control regardless of the
setting.

≥ The color phase cannot be adjusted when RGB

signals are input.

2

CHROMA

This control is used to adjust the image chroma. Any
value from 0 to 60 can be set. The default setting is

30.

<Note>

The chroma cannot be adjusted when RGB signals
are input or when the MONO setting is ON.

3

BRIGHT

This control is used to adjust the image brightness.
Any value from 0 to 60 can be set. The default setting
is 30.
However, the brightness cannot be adjusted when
blanking is displayed using the HV DELAY function.

4

CONTRAST

This control is used to adjust the image contrast. Any
value from 0 to 60 can be set. The default setting is

50.

5

FUNCTION/ENTER button

This button is used to enter changes or settings while
a menu is displayed.
If there is no menu display, the button's function
changes depending on which FUNCTION item on the
menu is selected. One of the following three items
can be selected. (Refer to page 19)

UNDEF: No function is allocated to this item.
HV DELAY

: Image blanking is displayed. Each time

the button is pressed, the blanking
display is switched by one setting in the
following sequence: H blanking display
> V blanking display > H and V
blanking display > no blanking display.

WFM ON/OFF

: The Y signal (luminance) waveform is

displayed at the bottom right of the
image. When the button is pressed
again, the display is cleared.
When waveforms are displayed in the
16:9 mode, the image displayed on the
screen moves to the upper part of the
screen so that it will not be
superimposed onto the waveform
display.

<Notes>

≥ In order for this function to be used, it is necessary to

select WFM as the FUNCTION item setting on the
SYSTEM CONFIG screen, and then select FUNCTION
as the WFM item setting.

≥ The WFM function is a simplified one and, as such,

finely detailed waveforms may not be displayed
accurately.
In addition, differences in the input signal format or
input function may result in the display having a
different horizontal width.

The image remains unchanged in the 4:3
mode.
