|Question:||What are the technical and business advantages of LCD technology compared with CRT and Plasma?|
LCD monitors offer significant reductions in Total Cost of Ownership (TCO) as well as radical improvements in production flexibility.
|Question:||How does the lifetime expectancy of LCD monitors compare with that of CRT?|
|Answer :||LCD monitors can be typically expected to offer double the operational lifetime of a CRT monitor. This is because CRT technology uses a high
voltage source to direct an electron beam at the screen’s phosphor layer, inevitably causing ‘wear and tear’ on the CRT’s electron gun. In contrast,
LCD panel life is mainly determined by the long life backlight that generates the brightness of the LCD picture.
|Question:||Are LCD monitors susceptible to magnetic fields?|
|Answer :||No. One of the great advantages of using LCD monitors is that unlike CRTs they do not suffer from any magnetic field interference. This means
installation can be simpler and faster, without compromising picture quality, as well as saving money on maintaining product performance.
With LCD monitors, picture geometry and convergence are also stable, compared with the need for periodic corrections to a CRT monitor.
|Question:||Does the LCD panel determine the performance of a LCD monitor?|
|Answer :||The type of LCD panel used in a monitor is clearly very important, however it is not the only factor determining performance. The new separate type
LUMA Series features a Sony engineered color processing technology called ChromaTru. This new technology allows users to closely match the
color performance between various size LUMA LCD monitors as well as emulate the color of SMPTE-C, EBU or ITU-709 standards. Combined
with Sony's X-Algorithm signal processing, Sony LUMA monitors clearly provide the precise picture quality that a professional videographer
demands. By providing full digital control and ultimate signal processing, picture performance of a LUMA monitors is greatly improved compared
with other designs that do not include this processing technology.
|Question:||What are the differences between a professional LMD monitor and a computer LCD monitor?|
|Answer :||Monitors for professional video applications differ substantially from conventional computer monitors in terms of picture processing demands, inputs and features. Computer LCD monitors are typically intended to display text and graphics. Consequently, they are optimized to enhance still images by making them more legible and vibrant. By contrast, the primary application for LUMA monitors is moving video. This demands a faster LCD response time, as well as 8-bit LCD drivers for accurate color and grey reproduction, whereas most computer LCD monitors currently use only 6-bit drivers. Video processing must also be powerful enough to look ‘ahead of’ and ‘behind’ each frame so that rapid changes in picture content can be processed for an accurate reproduction of the video signal. Inputs for computer displays are either DVI or RGBHV which are not standards used for professional video production. Monitors for video production applications must in contrast support HDSDI (SMPTE 292M) or SDI (SMPTE 259M), while NTSC/PAL as composite or component signals must also be displayed. These signal formats are usually not supported in computer monitors. LUMA monitors also provide additional functionality that is mandatory for production video applications, including a wide range of white balance settings as well as various gamma curves to fulfil professional picture requirements|
|Question:||What’s the difference between a professional LUMA monitor and a LCD television set?|
|Answer :||In essence, a TV is designed to ‘disguise’ picture flaws in order to maximize
viewer’s enjoyment of transmitted signals. A LUMA monitor, in contrast, is
designed to reproduce pictures precisely in accordance with the input signal. For example, if an input signal includes picture noise the LUMA
monitor will precisely display this noise so a professional user can easily see and correct the problem at source. A consumer TV, in contrast, features
noise reduction features to eliminate noise – concealing any source problems. A LUMA monitor is also designed to a higher specification and
supports a considerably wider range of professional inputs – with appropriate interfaces – as well as including numerous features specific to the professional market.
|Question:||What are the practical differences between LCD and PLASMA technology?|
|Answer :||LCD technology offers a number of inherent advantages. LCD picture quality is brighter and higher in contrast with less picture noise and no undesirable
‘burn-in’ effects*. LCD screens also have a much longer lifespan, are much less fragile, generate less heat and weigh less. Although traditionally more expensive, advances in LCD technology
are bringing down this cost difference. The new 32-inch** LMD-322W monitor is designed to offer LCD advantages to traditional plasma market such as presentation applications and multiple image display in master control room.
*The plasma burn-in effect is where a static image is permanently burnt onto the screen.

|Question:||What advantages do LUMA Series monitors offer for video production applications?|
|Answer :||The most important advantage of LUMA monitor technology is its ability to emulate the color truthfully and reproduce moving pictures accurately. This new ChromaTru technology allows users to emulate the color of SMPTE-C, EBU or ITU-709 standards. Patented Sony X-Algorithm processing ensures the most suitable conversion of interlaced to progressive images by detecting the strongest correlation between pixels for a new interpolated pixel calculation. This result in far superior picture performance.|
|Question:||Do LUMA Series monitors provide any protection for the LCD panel?|
|Answer :||Yes. The LCD panels used in all LUMA Series monitors feature a robust anti-reflective-coated protection layer, which minimize the risk of scratching the panel during transportation. This coating has two unique characteristics: it provides a high transmission rate of the internal light source to keep the picture as bright as possible, while keeping the reflection of ambient light to a minimum. As a result, high contrast is still maintained under bright ambient lighting conditions – even in dark areas of the picture – offering a clear benefit over CRT monitors. (Note: the LMD-1410 and LMD-2010 models do not have this protective coating).|
|Question:||What is the maximum viewing angle available for the LUMA Series monitors?|
|Answer :||Sony employs new liquid crystal technology that is suitable for handling high definition video and also offers extremely wide viewing angles. Typical off-axis viewing is possible over a range of as much as 170 degrees with no polarization artifacts.|
|Question:||What picture size is available in the LUMA monitor range?|
|Answer :||The LUMA Series currently ranges from 4-inch to 32-inch* in 4:3 or 16:9 aspect ratio. This covers the majority of production applications in outdoor or indoor
environments. In the future, Sony will further increase the LUMA monitor line-up to expand the range of applications for LUMA LCD monitors.

|Question:||What is the resolution of the panel?|
|Answer :||True picture performance depends on screen size, aspect ratio and also processing technology. For the wide screens LMD-322W, LMD-232W, LMD-172W the panel resolution is about 1280 by 768 pixels, while the 4:3 LMD-210S and LMD-152 feature 1024 by 768 pixels resolution. However, defining picture performance by simply counting the number of pixels is not in itself sufficient. Other parameters need to be taken into consideration. For instance, Sony’s high quality I/P processing technology and 8-bit LCD panel drivers contribute significantly to improve overall picture performance by providing accurate reproduction of moving images.|
|Question:||Can a LUMA monitor be used as a reference monitor?|
|Answer :||Not yet. LCD picture quality is improving dramatically and advanced Sony processing technologies mean LUMA monitors are perfectly suitable for the vast majority of viewing applications. However, the Sony BVM Series of CRT monitors will continue to provide state-of-the-art picture quality for critical broadcast reference monitoring applications.|
|Question:||What are the main limitations of a LUMA monitor compared to a reference monitor?|
|Answer :||Compared to reference quality CRT monitors, the main limitations of LCD technology today are black level and black detail, time response, viewing angle and colour gamut –although the latter is close to SMPTE or EBU standards. Sony BVM Series reference monitors can display a wide range of black level details and since they use CRT technology, they provide a better black gamma. Also, the SMPTE or EBU has standardized on one phosphor set that is accurate and repeatable for CRT monitors – as yet there is no equivalent of this for LCD technology. For these reasons LUMA monitors are currently intended for general viewing applications.|

|Question:||Are these monitors 16:9 and 4:3 switchable?|
|Answer :||Yes. All the above LUMA monitors can switch the aspect ratio to 16:9 or 4:3 depending on native aspect ratio.|
|Question:||What are the advantages of the two-piece design for the LUMA Series?|
|Answer :||The slim, lightweight nature of LCD panels compared with CRTs simplifies installation and enhances operational flexibility. Separating the LCD display and processing
unit maximizes these benefits without compromising the monitor’s functionality or range of inputs;
• Maximum installation flexibility with ultra-compact and lightweight LCD panel for indoor and outdoor operation.
• Simplified cabling demands due to centralized inputs on the processor unit with a single cable from processor unit to LCD panel.
• Direct access to key user controls with PVM-style functionality on processing unit.
