thoroughly and retain it for future reference.
The explanation given in this manual can be applied to
the following models unless noted otherwise.
When explanation differs among models, this is clearly
indicated in this manual.
• BVM-14M4DE/14M4E (14-inch monitor)

Table of Contents
On safety
• Operate the unit only with a power source as
specified in “Specifications” section.
• The nameplate indicating operating voltage, power
consumption, etc., is located at the rear.
• Should any solid object or liquid fall into the cabinet,
unplug the unit and have it checked by qualified
personnel before operating it any further.
• Do not drop or place heavy objects on the power
cord. If the power cord is damaged, turn off the
power immediately. It is dangerous to use the unit
with a damaged power cord.
• Unplug the unit from the wall outlet if it is not to be
used for several days or more.
• Disconnect the power cord from the AC outlet by
grasping the plug, not by pulling the cord.
• The socket-outlet shall be installed near the
equipment and shall be easily accessible.
On installation
• Allow adequate air circulation to prevent internal
heat build-up.
Do not place the unit on surfaces (rugs, blankets,
etc.) or near materials (curtains, draperies) that may
block the ventilation holes.
• Do not install the unit in a location near heat sources
such as radiators or air ducts, or in a place subject to
direct sunlight, excessive dust, mechanical vibration
or shock.
On cleaning
To keep the unit looking brand-new, periodically clean
it with a mild detergent solution. Never use strong
solvents such as thinner or benzine, or abrasive
cleansers since they will damage the cabinet. As a
safety precaution, unplug the unit before cleaning it.
On repacking
Do not throw away the carton and packing materials.
They make an ideal container which to transport the
unit. When shipping the unit to another location,
repack it as illustrated on the carton.
If you have any questions about this unit, contact your
authorized Sony dealer.

Picture
HR (High Resolution) Trinitron 1) picture tube
HR Trinitron tube provides a high resolution picture.
Horizontal resolution is more than 800 TV lines at the
center of the picture.
Comb filter
When NTSC video signals are received, a comb filter
activates to make more accurate Y/C separation. This
contributes to less of a decrease in resolution, cross
color and cross luminance phenomena.
Beam current feedback circuit
The built-in beam current feedback circuit assures
stable white balance.
Four color system available
The monitor can display NTSC, PAL, SECAM and
NTSC4.432) signals. The appropriate color system is
selected automatically.
Blue only mode
In the blue only mode, an apparent monochrome
display is obtained with all three cathodes driven with
a blue signal. This facilitates color saturation and
phase adjustments and observation of VCR noise.
Features
1) “Trinitron” is a registered trademark of Sony
Corporation.
2) The NTSC4.43 system refers to an NTSC color system in
which the subcarrier frequency is modified to 4.43MHz.
When an NTSC recorded video program is played back
with a Trident (PAL/SECAM/NTSC4.43) VTR, the
NTSC4.43 signal is output.

Input
COMPONENT SDI3) input/output connectors4)
for BVM-20M4DE/14M4DE
SMPTE 259M 4:2:2 serial digital signal from a digital
VCR can be input and output through these
connectors.
When you install a Sony Component SDI kit <Audio>
BKM-102 (not supplied), you can monitor the sound
from serial digital input signals with the picture.
Analog RGB/component input connectors
Analog RGB or component (Y, R-Y and B-Y) signals
from video equipment can be input through these
connectors.
Y/C input connectors
The video signal, split into the chrominance signal (C)
and the luminance signal (Y), can be input through this
connector, eliminating the interference between the
two signals, which tends to occur in a composite video
signal, ensuring video quality.
External sync input
When the EXT SYNC selector is in the on position,
the monitor can be operated on the sync signal
supplied from an external sync generator.
Automatic termination
(connector with mark only)
The input connector is terminated at 75 ohms inside
when no cable is connected to the loop-through output
connector. When a cable is connected to an output
connector, the 75-ohm termination is automatically
released.
3) SDI: Serial Digital Interface
4) The Sony Component SDI Kit BKM-101C (for video) is
built in BVM-20M4DE/14M4DE.

SDI (Serial Digital Interface) Kit (for audio) for
BVM-20M4DE/14M4DE
By using the Sony BKM-102 Component SDI Kit (for
audio, optional), you can monitor SMPTE 259M 4:2:2
serial digital audio signal from a digital VCR with the
picture.
SDI (Serial Digital Interface) Kit for BVM-
20M4E/14M4E
By using the following optional SDI Kits, the monitor
can display SMPTE 259M 4:2:2 serial digital signal
from a digital VCR. (ex. Sony 4:2:2 VCR)
- BKM-101C: Component SDI Kit (for video)
- BKM-102: Component SDI Kit (for audio)
Note
When the serial number of the BKM-101C you want to
connect is less than 2,010,000, an optional connecting
harness (part no. 1-900-230-35) will be required.
Serial Remote Interface Kit
By using the Sony BKM-103 Serial Remote Interface
Kit (optional), the monitor can be controlled from
personal computers via the RS-422A serial interface.
Functions
Underscan mode
The signal normally scanned outside of the screen can
be monitored in the underscan mode.
Note
When the monitor is in the underscan mode, the dark
RGB scanning lines may appear on the top edge of the
screen. These are caused by an internal test signal,
rather than the input signal.
Horizontal/vertical delay mode
The horizontal and vertical sync signals can be
checked simultaneously in the H/V delay mode.
Auto/manual degaussing
Degaussing of the screen can be performed
automatically when the power is turned on, or
manually by pressing the DEGAUSS button.
On-screen menus
You can set color temperature, CHROMA SET UP,
and other settings by using the on-screen menus.
