Chapter 1 Introduction Welcome to Dolby® professional video! The Dolby Professional Reference Monitor (PRM‐4200) is designed for the postproduction, film, and television broadcast industries. The PRM‐4200 has a resolution of 1,920 × 1,080 pixels and a refresh rate of 120 Hz, utilizing Dolby Laboratories’ dual‐modulation technology. This enables the 42‐inch (diagonal) flat‐panel display to deliver extended dynamic range and reveal true and deep blacks with higher contrast across its entire color spectrum.

Introduction You operate the PRM‐4200 using the Dolby Remote Control. You can use the Remote on the desktop or in a standard 19‐inch equipment rack. For complete details on the Remote, see Chapter 2.
Chapter 2 Using the Professional Reference Monitor This chapter explains how to use the Dolby® PRM‐4200. 2.1 Installing the PRM-4200 To install the Dolby® PRM‐4200: 1. Position the PRM‐4200 in a well‐ventilated area, at a minimum of 12 inches from a side wall and 12 inches from a rear wall. In addition, if you install the PRM‐4200 in any type of enclosure, air should flow into the enclosure at a minimum of 200 cubic feet per minute (CFM) air at 25°C.
Using the Professional Reference Monitor 2. Connect your required inputs and outputs on the PRM‐4200 rear panel, as shown in Figure 2‐2. Figure 2‐2 To Remote Control (Ethernet) To external network (Ethernet) DVI in Audio sync out HD-SDI A & B in A HD-SDI A & B out Figure 2-2 • Use the HD‐SDI A input for single‐link formats. • Use the HD‐SDI A and B inputs for dual‐link formats. Note: 3.
Installing the PRM-4200 4. Connect the PRM‐4200 power cable to an AC power source, then press the power switch to turn on the monitor, as shown in Figure 2‐4. Figure 2‐4 Press power switch Connect AC power Figure 2-4 Connect AC Power and Turn On Monitor While the Remote is booting, the Dolby logo appears on its user display, and then a message indicates that it is searching for a connected monitor, as shown in Figure 2‐5.
Using the Professional Reference Monitor 2.2 Remote Control Basics We designed the Remote for use on a desktop or in a standard 19‐inch equipment rack (rack tray for mounting included). You can access the most frequently used functions through front‐panel buttons, while additional functions are accessible in menus that appear on the user display.

Remote Control Basics Reference Mode Keys The reference modes provide highly accurate colorimetry and gray‐scale performance. They allow a user to modify display related parameters only (brightness, contrast, and maximum luminance), and to toggle between two groups of display related settings. We created these modes for the colorist, as the main work areas. There are two reference modes: CRT REFERENCE This mode provides a maximum luminance of 120 cd/m2, continuously variable from 40 cd/m2.
Using the Professional Reference Monitor STATUS The STATUS key displays the PRM‐4200 core operating parameters for the selected reference or emulation mode. (See the example for CRT Reference mode in Figure 2‐6.) It also provides access to a SMPTE timecode display. 2.2.3 Remote Controller LCD Display The Remote LCD user display provides screens and menus that allow you to access, edit, and configure many PRM‐4200 parameters. 2.2.
Remote Control Basics 2.2.5 Numerical Keys Figure 2‐12 Figure 2-12 Numerical Keypad You use the numerical keys to enter values in the Remote data entry fields. You can use the backspace key in the lower‐left corner to delete characters from right to left. Using the Numerical Keys to Save Custom Presets You can also use the numerical keys to save and load custom presets, as described in Section 2.5. Each preset saves the current state of all PRM‐4200 parameters.
Using the Professional Reference Monitor 2.2.8 USB Ports The Remote has three USB 2.0 compliant ports. Two are located on the left side of the Remote front panel (oriented vertically), and one is located on the right side panel. The USB ports are provided to connect memory devices. You can insert USB memory devices to save 1D and 3D LUTs (to the PRM‐4200, not on the Remote) and to upgrade the system. 2.2.
Editing the Reference and Emulation Parameters 2.3 Editing the Reference and Emulation Parameters You can edit the PRM‐4200 reference and emulation parameters using the Remote. Table 2‐4 shows the edit mode parameters for the CRT Reference and Dynamic Reference modes, and the Custom 1, Custom 2, LCD, and PDP emulation modes.
Using the Professional Reference Monitor The key illuminates in yellow and the CRT Mode: Input screen appears with Input Format and Video Range parameters, as shown in Figure 2‐15. This is the first CRT reference editing screen. The Input tab at the bottom‐left side of the screen is highlighted, indicating it is the active menu selection. Figure 2‐15 Active menu Figure 2-15 CRT Mode: Input Screen 3.
Editing the Reference and Emulation Parameters 4. Press the down arrow key to activate the tab menu, then press the right arrow key (or the EDIT key). The CRT Mode: Brightness screen appears with a slider display, which indicates the current brightness setting, as shown in Figure 2‐17. Figure 2‐17 Figure 2-17 CRT Mode: Brightness Screen 5. To change the current brightness setting: • If the B/C LOCK (third key below CAL) is illuminated, press this key to unlock the brightness control.
Using the Professional Reference Monitor When you change the default contrast setting, the LED next to its rotary control knob illuminates in blue. 8. Press the right arrow key (or the EDIT key).

In addition, when you save a preset, it stores information for an active LUT. 1.
Appendix A PRM-4200 Maintenance This chapter describes some basic maintenance procedures for the Dolby® PRM‐4200. A.1 Replacing the Filter Your PRM‐4200 has a filter installed that you need to check periodically. When the filter contains an excessive amount of dust, you need to replace it. To replace the PRM‐4200 filter: 1. Obtain a new filter from Dolby Laboratories (Dolby Part Number 6321540). 2.
PRM-4200 Maintenance 4. Place the filter door (screws side down) on a level surface, then remove the filter by sliding it through the retaining brackets, as shown in Figure A‐2. Figure A-2 5. Remove Filter Install the replacement filter by sliding it into the filter door, as shown in Figure A‐3. Figure A‐3 Figure A-3 6.
