Accurate Colour Reproduction

Nonlinear Cubic Conversion Colour
Management System
The nonlinear cubic conversion colour
management system of the BVM-L230
uses a unique 3-D LUT (look-up table)
to reproduce an extremely wide colour
gamut, thus offering more accurate
colour reproduction. It offers highly
accurate chromaticity throughout the
entire grayscale. The combination of
its high-purity LED backlight system, to-
gether with this colour management
system, allows the BVM-L230 to accu-
rately reproduce colour gamut that
replicate broadcast standards such
as ITU-R BT.709, and EBU and SMPTE-C
phosphor standards. In addition, the
BVM-L230 offers a unique “WIDE” gamut
that reproduces a wider colour space.
This can be used to monitor content
intended for applications other than
direct broadcast, and it can also emu-
late the D-Cine* colour gamut used in
digital cinema production. Compared
to past CRT monitors, which offer only
one colour gamut per model, the
BVM-L230 allows these colour gamuts
to be selected and reproduced on the
same monitor – a feature only made
possible by the technologies used in
the Sony BVM-L230 monitor.
* “D-Cine” is a colour gamut emulating the colour
gamut described in SMPTE 431-2 Table A1. However,
the chromaticity of the green-red region is not
covered in full.

Precision Imaging

Full HD Panel with 10-bit Driver
The BVM-L230 achieves both high reso-
lution and stunning colour depth using
a full 1920 x 1080 HD LCD panel and
precise 10-bit driver.
Newly Developed I/P Conversion Technology
The BVM-L230 uses a sophisticated
I/P conversion technique that keeps
artefacts that are often seen in typical
LCD monitors to a minimum, such as
edge jaggedness, conversion errors,
and a picture delay that is less than
one field.

Quality Picture Consistency

High Accuracy Display Engine
Each and every BVM-L230 monitor is
carefully calibrated at the factory on an
individual basis, providing a high level
of accuracy and stability for character-
istics such as gamma and uniformity.
Colour Feedback System
Using a colour feedback system, the
BVM-L230 achieves the stability called
for with master monitor applications.
Ultra-high precision Uniformity Correction
Typically, LCD monitors exhibit poor
uniformity per formance. With the
BVM-L230, white can be reproduced
uniformly at every point of the screen.
This is due to the use of two advanced
technologies: precise adjustment of the
LCD panel characteristics and sophis-
ticated LED backlight control. At the
factory, grayscale levels are precisely
measured at each area of the panel and
if differences are detected between
areas, they are accurately corrected
by electrical means. Secondly, the so-
phisticated LED backlight system also
contributes to the BVM-L230’s high
level of uniformity. This is because RGB
sensors are aligned together with the
R, G and B LEDs of the backlight to
constantly monitor and control the
luminance level of each backlight
colour. When inconsistent luminance is
detected, the colour feedback system
adjusts the light intensity of the corre-
sponding LEDs – red, green, or blue –in
that specific area to maintain accurate
luminance uniformity of the backlight.
These two technologies combined
together allow the BVM-L230 monitor
to provide an extra level of uniformity.
04 Superb Picture Quality and Stable Colour Temperature
The BVM-L230 incorporates three unique technologies that have been cus tomised for exclusive use in this monitor:
a high-grade 23-inch* full resolution LCD panel, a precision backlight system, and a unique professional display
engine not found in any other monitor. This has resulted in the highly reliable BVM-L230, which offers the accurate colour
reproduction, precision imaging and quality picture consistency required by today’s most demanding master monitoring
applications. Using these technologies, the BVM-L230 not only achieves the quality of its predecessor BVM-A and
BVM-D Series CRT monitors, but also adds innovative features for today’s new master monitoring needs.
