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 balan~e.
Four color
system
available
The monitor can display NTSC, PAL, SECAM and
NTSCw
21
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.

Input
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 J\/1,- mark only)
The input connector is terminated al 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.
2) The NTSCu, 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 (PAUSECAMJNTSC. o) VTR, the NTSC..o signal is
oulput.

The signal normally scanned outside of the screen can
be
monitored in the underscan mode.
11111111
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 HIV 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 bulton.

-BKM-IOIC:
Component SDI Kit (for video)
- BKM-102:
Component SDI Kit (for audio)
