    The Dolby® Professional Reference Monitor PRM-4220 enables the creative process for colorists and cinematographers by ensuring that the final image will reflect exactly what you see on the display. The most accurate color-correction monitor available, it displays the full dynamic range that the latest advanced digital cameras can capture.

    • Renders superior black-level performance, with true blacks, highly accurate dark detail, and precise linearity maintained across the entire gray scale
    • Accurately displays DCI P3, all high-definition formats over HD-SDI, and 2K video content
    • Allows accurate viewing of all image details in the darks, and highlights what other monitors typically clip
    • Supports not only today's 10-bit video formats but also emerging 12-bit formats without dithering or downscaling of the color gamut
    • Displays color looks and previsualization with 1D and 3D look-up tables (LUTs)
    • Provides the exceptional reliability of an LCD display

    As a color-grading monitor, the Dolby Professional Reference Monitor uses 3D LUTs to emulate the full gamut and contrast ratio of film, as well as the color profile of digital cameras. This makes DCI P3 color grading possible without the use of a digital projector.

    Each Dolby video reference monitor can replace a collection of other professional video monitors, allowing HD and digital cinema workflows in the same room.

    "The ease of use and flexibility of the monitor, its robust build, and future-ready technology make it an obvious investment in a growing part of our business."
    -Kevin Horsewood, Colorist, Prime Focus 

    "With the number of films being processed by our studios rapidly rising, it is necessary that we ensure they meet the most exacting production standards possible. The [Dolby Professional Reference Monitor] guarantees that viewers will perceive a film exactly as its director intended it to be seen."
    -Surachedh Assawaruenganun, CEO, Kantana Digital Post 

    "Why spend the money on the Dolby® monitor? The answer is simple: confidence. Having technological confidence in a display device gives confidence to the colorist. A confident colorist helps make a confident client."
    -Michael Cioni, CEO, Light Iron "Several displays in the market use EBU Tech 3320 as a benchmark. To date, no display officially measured by an EBU Member's lab has fulfilled all requirements. The latest (and closest to fulfilling the whole specification Tech 3320 v2.0 [2010]) is the [Dolby Professional Reference Monitor] measured by the IRT (early 2011). In addition, it has the advantage of being the only large-size flat panel display (42 inches). While 24 inches is the common size for production displays, larger-size reference monitors are needed to assess consistently the quality of HDTV content normally viewed on displays larger than 32 inches." -EBU Tech-i, Issue 10, December 2011, pages 10-11 

    "The Dolby Professional Reference Monitor allows us to help content creators realize their artistic vision with the confidence of the highest level of color accuracy available today."
    -Stefan Sonnenfeld, President, Creative Services, Deluxe Entertainment Services Group 

    "Dolby has the 'wow' factor that hits you as you enter the suite. No other comparable product has the picture quality and also the scale of this monitor. We have not seen any other LCD monitor capable of handling an image in the way the Dolby product does. Nice whites, nice blacks, nice soft color, no artifacts. Very impressive."
    -Scott Harris, Colorist, Glassworks Amsterdam  

    "The Dolby monitor is a big part of bringing in more work-or closing the deal, at least. It gives us a differentiator in Toronto. Our color-correct business has increased by 70 percent, and it is really due to the monitor." -John Laing, Managing Partner, Urban Post Production "The Dolby monitor changes the game completely." -VP, Postproduction Technology, major film studio 

    "Feature-film production is rapidly moving toward a model where calibrated displays are needed near set. The Dolby Professional Reference Monitor allows us to see exactly what has been shot. If there are any questions, it ends the conversation." -Marc Dando, Managing Director, Codex Digital 

    "I used the Dolby Dynamic Reference mode for some tradeshow presentations of Alexa material graded in Film Master, and this monitor is as close to looking out a window as I have ever seen. Also, after a long day of intense grading, I felt none of the eyestrain that I have noticed from other monitors."
    -Kevin Shaw, Colorist, Instructor, and Consultant; Cofounder of the International Colorist Academy 

    "My biggest like about the monitor is the size-I swear that you'll never see your image looking that good again. There are no other types of displays out there that can match the image performance and accuracy of the Dolby reference monitor."
     -Nigel Hadley, Nucoda Senior Product Manager, Image Systems
