Dolby Professional Reference Monitor PRM-4220


Dolby PRM-4200 Reference Monitor – USED

Unit and accessories are complete and recently upgraded and calibrated by Dolby.


The Dolby Professional Reference Monitor PRM-4220 is a Grade 1 monitor that offers a
new standard for critical viewing applications. The monitor renders true black levels, highly
accurate dark detail, and the most precise color accuracy possible, across a wide dynamic
range at all luminance levels and in all formats.

Its support of 3D LUTs means the monitor can be calibrated to exactly match digital screening
environments and emulate the response of film-print stocks during the DI process. With this
capability, production and postproduction facilities can establish accurate color grading suites
without installing a costly DCI P3 projection system. On set, the support of 1D and 3D LUTs
allows the monitor to display color looks and previsualization with absolute accuracy.

The Dolby Professional Reference Monitor meets the range of video viewing needs from all
HD formats, 2K, and DCI P3. Further, the PRM-4220, with its LCD and Plasma emulation
modes, allows the colorist to emulate the types of displays commonly found in the home
environment, closing the “viewing gap” between the colorist and end user. The PRM-4220
eliminates the need to use separate monitors for different tasks.

Dolby PRM-4220 Specifications

The Dolby Professional Reference Monitor PRM-4220 is the first monitor that can actually
display 100 percent of DCI P3 with linear color accuracy across the entire gray scale.
Featuring a 42-inch (1,067 mm) diagonal LCD flat-panel screen with a resolution of
1920 × 1080 pixels and a refresh rate of 120 Hz, the Dolby Professional Reference Monitor
delivers a wide viewing area of plus or minus 45 degrees.

An external remote controller handles all control functions, so there are no onscreen displays
to interfere with the image on the monitor. The remote may be rack-mounted or used on the
desktop, and it gives immediate, intuitive access to all of the monitor’s features, functions, and
parameters through a simple, easy-to-use menu structure.

In today’s postproduction environment where versatility is an important requirement, the Dolby
Professional Reference Monitor is equipped to support most configurations. Two digital video

ITU-R BT.1358, SMPTE 274M, and SMPTE RP211. There are two output connectors with
support for 1.5G and 3G SDI, single and dual link.

Power consumption is 1,000 VA maximum, with line voltage compatibility of 85 to 260 VAC,
50 to 60 Hz. The operating temperature range is 0 to 35 degrees Celsius, with the optimum
temperature at 20 degrees Celsius (plus or minus 5 degrees), and a storage temperature
range of –20 to +70 degrees Celsius. It weighs 150 lb (68 kg).
