Variety of Display Modes

Interlace Display
The Interlace Display mode of the BVM-L230 can
display interlace input signals as interlace fields. As
with the Native Scan function, the Interlace Display
mode offers faithful reproduction of the input signal
and the displayed interlace fields are free from picture
degradation that can occur by the monitor’s I/P
conversion process.
Most flat-panel monitors can only display progressive
images at the input signal’s frame rate. In addition to
this conventional display method, the BVM-L230 has two
unique display modes: Black Frame Insertion Display
and Interlace Display.
The BVM-L230 monitor incorporates a Gamut Error
Display function that detects irregular signal input.
When an irregular signal is detected, the BVM-L230
indicates this with a ZEBRA pattern over the relevant
area of the picture. Irregular signal data can include
non-standard input signals and video signals
exceeding the video level (selectable), which can be
generated during the signal conversion from HD
component to RGB. The Gamut Error Display is a
convenient feature that instantly alerts viewers of such
signals without using a waveform monitor.
IBlack Frame Insertion Display
Combining its high frame-rate operation with a unique
Black Frame Insertion technology, the BVM-L230
dramatically reduces motion blur, an artifact that is
inherent to LCD devices. Black Frame Insertion
technology generates a “black” frame and inserts this
in every other picture frame. As a result, all of the
panel’s LCD molecules are reset to their default
alignments, before the next picture frame is displayed.
This effectively eliminates the image lag caused by
inconsistencies in the speed at which LCD molecules
are realigned in accordance with the video signal
change. Because the number of frames is doubled,
Black Frame Insertion Display reproduces the
combined picture content at twice the speed of the
input signal’s frame rate*.
* The frame rates of 120 Hz and 100 Hz are supported.
