Sony Trimaster BVM-L231 Operation Manual page 9

The signal delay is decreased by judging the animation or
still picture from the past video signal. Film cadence
processing, which converts the signal composed of 2-2·2-
3·2-3-3-2 pull down to the I/P signal closely following the
original, is also selectable.
Interlace display mode
The interlace signal is displayed as the interlace picture by
inserting the black line without I/P conversion processing.
A picture faithful to the original signal and with the same
feel as a CRT is gained.
For setting the display, see "Selecting Display Mode" on
page 88.
Black frame insertion display mode
Monitor blur caused by the holding-type display of the
LCD is decreased by blinking the backlight in
synchronization with the LCD display frame in double
frame rate (100/120Hz) operation of the LCD panel.
For setting the display, see "Selecting Display Mode" on
page 88.
Available to a multi signal format
The monitor supports various input signals such as 720 ×
576/50i to 1920 × 1080/50P, 60P, digital cinema (D-Cine)
2048 × 1080/24P and variable computer signals up to
WUXGA (1920 × 1200). A DVI-D (HDCP

HD frame capture function
The frame of the 3G/HD-SDI input signal is captured and
saved as a picture file in the "Memory Stick". This is used
to confirm the color tone and picture angle of the current
scene and recorded scene by using the multi display
(Picture&Picture) function.
* As the frame of the input signal is captured, the data and
marker set by the monitor is not reflected.
For the operation, see "Capturing the Picture of the HD
Signal (HD Frame Capture)" on page 94.
Multi display function
Two kinds of input signals are output on the monitor. You
can select from side by side, wipe, butterfly and blending
mode. This is useful for adjusting the color or comparing
two pictures.
For the operation, see "Displaying Two Signals on One
Screen (Picture&Picture)" on page 91.
Pixel zoom function
As part of the picture is magnified up to 8 times without
scaling processing, this is convenient for confirming a
minute part of the signal.
For the operation, see "Magnifying the Picture (Pixel
Zoom)" on page 92.
Safe area marker and aspect marker functions
The monitor is equipped with two area markers and center
marker as the safe area marker and aspect marker for
confirming the picture angle.
For the operation, see "Displaying the Area Marker or
Aspect Marker" on page 95.
Scan selection/Native scan display function
You can select from under scan (–3%), normal scan (0%)
and over scan (mask of the 5% over scan portion in the
normal scan) for the picture display.
The monitor is equipped with a native scan display
function which maps the pixel of the signal to the panel in
one-to-one mode. You can select the mode from ×1, ×2 or
Aspect Correction to display a signal in native mode. An
SD signal of non-square pixels (the number of H pixels of
the signal system is 720 or 1440) or a 640 × 480 SD signal
of DVI video/HDMI video is displayed correctly by
scaling processing of doubling for the V direction and
correct aspect ratio for the H direction, and the picture is
also optimized and displayed by modifying the aperture
coefficient value, filter coefficient value, etc. in Aspect
Correction mode.
For the operation, see "Selecting the Native Scan/Scan
Mode" on page 90.
Gamut error function
The signal outside the specified range (gamut error) caused
by the conversion of the format or during CG/CM
production is displayed in a zebra pattern.
Black detail mode display function
You can reduce to dull black color by backlight leaking and
precisely assess any parts with low color gradation.
You can decrease the black level up to 40% of the normal
2
display (100 cd/m at 100% signal). The parts with high
color gradation (higher than 75 IRE) are clipped by the
dynamic range of the circuit, but a zebra pattern
(selectable) is displayed in the clipped portions.
For the operation, see "Displaying the Picture in Black
Detail Mode" on page 93.
Aspect selectable function
A squeezed and recorded signal is displayed with the
correct angle. You can select from 4:3, 16:9, 1.896:1 and
2.39:1* aspect modes.
