PVM-L2300

Sony Extends its TRIMASTER Series With the PVM-L2300 TRIMASTER Broadcast Monitor

Since its introduction in 2006, Sony’s TRIMASTER™ technology has been widely adopted for high-end picture-monitoring applications, and acclaimed for its high picture quality, operability, and reliability. Sony now introduces a new TRIMASTER monitor for broadcast applications.

The PVM-L2300 is a 23-inch1 LCD

monitor with a customized WCG-CCFL

(Wide Colour Gamut CCFL) backlight

system designed for use in broadcast

applications. Built on the TRIMASTER

design concept, the PVM-L2300

monitor can reproduce images

consistent with the BVM-L231 TRIMASTER

master monitor. By incorporating the

same processing-engine technology

of the BVM-L231 master monitor, the

PVM-L2300 offers the superb picture

performance and sophisticated

features required by today’s broadcast

and critical picture-monitoring

applications. Also, the

PVM-L2300 can accept almost any

type of video and PC signal, both

analog and digital. The video interface

accepts analog composite signals up

to 3G SDI

signals from VGA to WUXGA.

, as well as HDMI™ and DVI

In addition, the PVM-L2300 offers great

afﬁnity between Sony’s professional

CRT monitors in terms of system

conﬁguration, installation, physical

size, functionality, and operational

convenience.

The PVM-L2300 is the ideal choice

for the next level of digital broadcast

system that requires smooth migration

– from CRT to LCD, SD to HD, and/or

interlace to progressive.

The PVM-L2300 incorporates the professional display engine used in Sony’s BVM-L231 master monitor. In addition, it also features a unique high-grade 23-inch

full resolution LCD panel and a high-quality WCG-CCFL (Wide Colour Gamut CCFL) backlight system. What is great about the PVM-L2300 monitor is that it conforms to broadcast-standard colour gamuts unlike some wide CCFL backlight system LCD monitors. As a result of all this, the PVM-L2300 offers a high level of picture quality, accuracy, and reliability.

Multiple Colour Gamuts (SMPTE-C, EBU, ITU-R BT.709)

The PVM-L2300 incorporates the same colour conversion system as the BVM-L231 master monitor – the nonlinear cubic conversion colour management system – which uses a unique 3-D LUT (look-up table) to reproduce precise colour gamuts throughout the entire grayscale. Also, while wide CCFL backlights can in general reproduce wider colour gamuts than conventional CCFL backlights, not all wide CCFLs are compatible with broadcast colour gamuts. The WCG-CCFL backlight of the PVM-L2300 is designed to emulate BVM-CRT colour gamuts. And combined with its unique

colour management system, this enables the PVM-L2300 to accurately reproduce colour gamuts that emulate

broadcast standards such as ITU-R BT.709, and EBU and SMPTE-C phosphor standards. Compared to past CRT monitors, which offer only one colour gamut per model, the PVM-L2300 allows these colour gamuts to be selected and reproduced on the same monitor – a feature only made possible by Sony’s unique monitor technologies.

2 The PVM-L2300 conforms to these colour standards.

Main features

Input Versatility

The PVM-L2300 can accept almost any SD or HD video format, both analog and digital, plus PC signals from VGA to WUXGA (1920 x 1200). In addition to a DVI-D and an HDMI interface equipped as standard, four option board slots are offered to conﬁ gure the PVM-L2300 according to different user needs. The optional analog interfaces accept composite, Y/C, Y/PB/PR, and RGB. Digital interfaces accept SDSDI, HD-SDI, Dual-Link HD-SDI, and 3G SDI inputs. Acceptable signal formats include: 525/60i, 625/50i, 525/60P, 625/50P, 720/50P and 720/60P, 10-bit/ 12-bit RGB 4:4:4 1080/24PsF, 1080/24P, 1080/25PsF, 1080/25P, 1080/50i, 1080/30PsF, 1080/30P and 1080/60i, 10-bit 4:2:2 1080/50P and 1080/60P.

3G SDI Interface (V1.1 Feature)

The PVM-L2300 can be equipped with an optional 3G SDI interface. The BKM-250TG 3G SDI interface board is compliant with the SMPTE 425 standard and requires only one single SDI cable to transmit up to 10-bit 4:2:2 1080/60P video signals. This optional 3G SDI interface offers a simple cabling solution for groups of video equipment rack-mounted behind a sub-control room.

Superb Picture Quality and Stable Colour Reproduction

Multi-format Signal Support up to 3G SDI

depth using the Wide Colour Gamut CCFL backlight system.

Professional Display Engine

The PVM-L2300 incorporates the display engine used in the BVM-L231 master monitor. This unique nonlinear cubic conversion colour management system, plus exclusively developed I/P conversion technology, enables the PVM-L2300 to reproduce images faithfully.

Consistent Picture Quality

Each and every PVM-L2300 monitor

is carefully calibrated at the factory

on an individual basis, providing a

high level of accuracy and stability for

characteristics such as gamma and

uniformity. Also, a feedback system

supports this stability by constantly

detecting both the luminance level

and white balance.

Digital Uniformity Correction

Typically, LCD monitors exhibit poor uniformity performance. With the PVM-L2300, white can be reproduced uniformly right across the screen. 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.

The PVM-L2300 incorporates the latest 10-bit LCD driver and can achieve both high resolution and stunning colour

Multi-format Signal Support up to 3G SDI

Flexible Input Conﬁguration

Like both the BVM CRT and LCD master monitor series, the PVM-L2300 uses a modular slot design so inputs can be conﬁgured according to individual needs. Four input board slots are available. Optional input boards and in almost any combination, allowing easier conﬁguration and better cost-perinput value. These option boards utilize only one slot each, so up to four cards can be installed for maximum ﬂexibility.
