Broadcast Master Monitor
BVM-L230
Fulfilling your master monitoring needs even further
-the BVM-L230 at the pinnacle of LCD monitoring
Responding to the continued demands for a true master monitor, Sony introduces the BVM-L230, a 23-inch* LCD
master monitor that uses the all-new TRIMASTER™technology.
The stunning performance of the BVM-L230 is attributable to three new devices – a customised 23-inch* full HD
LCD panel, a high precision backlight system, and a unique professional display engine used exclusively in this
monitor – all of which are optimised for producing images with master monitoring quality. This has resulted in
the highly reliable BVM-L230, which offers the accurate colour reproduction, precision imaging and quality picture
consistency required in today’s most demanding master monitoring applications. The BVM-L230 not only achieves
the quality of its predecessor BVM-A & BVM-D Series CRT monitors, but also adds innovative features for today’s
new master monitoring needs. These include a newly-developed colour space selection function, a unique Picture
& Picture display, and an interlace display mode to name just a few.
The BVM-L230 monitor presents a new solution for the full range of master monitoring applications, from
acquisition to editing to colour correction.

Preliminary
01 Customised LCD Panel – 23-inch Full
HD Resolution
The LCD panel has been developed exclusively
for use on the BVM-L230, based on strict master
monitor criteria. It offers a 10-bit driver, an industry
first for professional panels, and other high-level
specifications such as high operatingframe rates
and high-speed response.
02 Precision Backlight System
Using Sony designed high-purity LEDs, the
precision backlight system is also used exclusively in the BVM-L230. This enables the widest
colour space (gamut) ever offered in a Sony
monitor to fully cover broadcast-standard colour
spaces. The precision backlight system also
incorporates a uniformity control function and a
colour feedback system.
03 Professional Display Engine
The high-precision signal processing engine has
been developed based on master monitor criteria
and optimised for the BVM-L230. This engine
incorporates 12-bit output accuracy at each
process. It also provides a high-quality I/P
conversion algorithm and a highly accurate
colour management system.
Key Devices – New Developments
Customised LCD Panel – 23-inch Full HD Resolution Precision Backlight System Professional Display Engine
The BVM-L230 incorporates three unique devices that have been customised for use on this monitor:
Accurate Colour Reproduction Precision Imaging Quality Picture Consistency
01 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 highly precise colour
space, thus offering accurate colour reproduction.
02 Selectable Colour Space
(ITU-R BT.709, EBU, SMPTE-C, D-Cinema*)
The combination of a Sony high-purity LED backlight system, together with its colour management
system, allows the BVM-L230 to accurately
reproduce colour space that complies with
broadcast standards - ITU-R BT.709, EBU or
SMPTE-C. Furthermore, the BVM-L230 can
emulate the D-Cinema colourspace*, which is
used for digital cinema productions. Compared
to CRT monitors offering only one colour space
per model, the BVM-L230 allows these colour
spaces to be selected and reproduced on the
same monitor - a feature only made possible by
the technologies used exclusively in the Sony
BVM-L230 monitor.

03 Digital Uniformity
The colour feedback system of the BVM-L230
constantly monitors and compensates for any
colour shifts, maintaining accurate luminance
uniformity.
01 Full HD Panel with 10-bit Driver
The BVM-L230 achieves both high resolution
and stunning colour depth using a full 1920 x
1080* HD LCD panel and precise 10-bit driver
* The actual resolution of the LCD panel is 1920 x 1200.
02 Newly Developed I/P Conversion
Technology
The BVM-L230 uses a sophisticated I/P conversion technique that keeps edge jaggedness,
conversion errors and picture delays to a
minimum – phenomena that are often seen in
typical LCD monitors.
03 Black Frame Insertion
The BVM-L230 reduces motion blur by
combining its high frame rate (120/100/96Hz)
operation and black frame insertion technology
using the high frame rate panel and driving
engine.
01 High Accuracy Display Engine
The BVM-L230 uses a 12-bit display engine, which
allows images to be reproduced with high precision
for accurate evaluation and manipulation.
02 Panel Calibration
Each and every BVM-L230 monitor is carefully
calibrated at the factory on an individual basis,
providing a high level of accuracy and stability.
03 Colour Feedback System
Using a colour feedback system, the BVM-L230
achieves the stability called for in master monitors.
