Superb Picture Quality and Stable Color Temperature

Ultra-high precision Uniformity Correction
Typically, LCD monitors exhibit poor uniformity performance.
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 sophisticated 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 sophisticated 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 color. When inconsistent luminance is detected,
the color feedback system adjusts the light intensity of the
corresponding 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.
The BVM-L230 incorporates three unique technologies that have been customized for exclusive use in
this monitor: a high-grade 23-inch* full resolution LCD panel, a precision LED 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 color 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.

Main Features
Accurate Color Reproduction
• Nonlinear Cubic Conversion Color Management System
The nonlinear cubic conversion color management system
of the BVM-L230 uses a unique 3-D LUT (look-up table) to
reproduce precision wide color gamuts meeting SMPTE
and ITU standards, thus offering more accurate color
reproduction. It offers highly accurate tracking throughout
the entire grayscale. The combination of its high-purity
LED backlight system, together with this color management
system, allows the BVM-L230 to accurately reproduce
color gamuts that replicates broadcast standards such as
ITU-R BT.709, and EBU and SMPTE-C phosphor standards.
In addition, the BVM-L230 offers a unique “D-Cine” gamut
that reproduces the wider color space used for digital
intermediate work. Compared to past CRT monitors, which
offer only one color gamut per model, the BVM-L230
allows these color gamuts to be selected and reproduced
on the same monitor – a feature only made possible by
the technologies used in Sony’s BVM-L230 monitor.
* “D-Cine” is a color gamut emulating the color gamut described in SMPTE
RP 431-2-2007. 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 resolution and stunning
color 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 artifacts 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.
