o r P Dolby r e f e ence R Ask the experts Ian Lowe, Senior Manager at Dolby Laboratories, Inc. Dolby has recently been making waves in imaging with its PRM-4200 Professional Reference Monitor, but isn’t Dolby an audio company? Dolby has been involved with imaging technology for years, beginning with Dolby® Digital Cinema in 2005, then launching Dolby 3D for the cinema in 2007, and then in 2010 we introduced the Dolby PRM-4200 Professional Reference Monitor. Dolby has a long history of working with professionals in the content creation community, and this relationship allowed the company to understand the changes in display technology that were causing problems for the postproduction community. When Cathode Ray Tube (CRT) professional monitor production ceased in 2005, it created a real dilemma for users requiring critical viewing who, until then, had relied on the faithful Grade 1 CRT monitors, which were the reference standard. That’s where Dolby came in. We saw the opportunity to use our considerable expertise and worked closely with the industry to develop a viable replacement product for the CRT. Dolby developed the PRM- 4200, a 42 inch (diagonal) LCD/LED flat panel display, to fill the gap left by the CRT. The Dolby Professional Reference Monitor is the first flat-panel monitor that truly betters the CRT’s performance, delivering true blacks, exceptional dark detail, high contrast, and enhanced colour gamut. We believe it is one of the most consistent, 46 | TV-BAY MAGAZINE accurate reference monitors for creating any type of entertainment content. That’s why many in the industry are saying it has become the new standard for reference monitors. One of the most striking things about the PRM- 4200 is its size compared with other grading quality monitors. Why did you choose to make it a 42 inch panel? It’s a matter of the changing needs of professionals and the market. Whilst the old Grade 1 monitors are still being used for critical evaluation of image quality for movie and broadcast applications, the consumer viewing the same content on their TV at home has moved away from the CRT to larger LCD and Plasma TVs with an average size of around 40 inches. So, working with industry professionals, we looked at flat panel options for professional use and we decided that a 42 inch panel would be the optimum size. This is the size closest to what most consumers are watching TV and movies on at home. What makes the Dolby Professional Reference Monitor so different? The thing that makes the PRM-4200 genuinely different is not just the incredible quality, but also the amazing flexibility it has to emulate virtually any other display device, from consumer LCD or plasma TVs, to a Grade 1 CRT, and through to DLP projector in the DCI colour space. This means the Dolby Professional Reference Monitor can be used for DI-colour grading, without the use of a digital projector. As for standards, it fully supports Rec709 and DCI-P3 colour space, whilst allowing the display of all high- definition formats via HD-SDI, and 2K content, either scaled or pixel-by-pixel. The monitor supports the luminance level required for DCI, from 48 cd/m ², through to 120 cd/m ² for Rec709. Dolby has further extended the performance of the Grade 1 monitor by being the first monitor to display a full 12-bit input in either RGB or XYZ format via dual link HD-SDI. It of course supports standard 10-bit inputs in component or RGB format via HD-SDI. >>
