Chapter 1
Introduction
Welcome to Dolby® professional video!
The Dolby Professional Reference Monitor (PRM‐4220) is designed for the postproduction, film, and television broadcast industries. The PRM‐4220 has a resolution of 1,920 × 1,080 pixels and a refresh rate of 120 Hz, utilizing Dolby Laboratories’ dual‐modulation RGB backlight 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 gamut.The PRM‐4220 complies with the industry standard color primaries (ITU‐R BT.709 [also referred to as Rec. 709], DCI P3, SMPTE‐C, and EBU) and accepts the CIE 1931 XYZ color space. We designed the PRM‐4220 to equal or exceed the performance characteristics of a reference CRT display. In addition, the PRM‐4220 can emulate consumer LCD and plasma display panel (PDP) displays, providing the colorist with an immediate quality control reference point while in the grading suite. With the use of custom 3D lookup tables (LUTs), the PRM‐4220 can also display other user‐specified properties.

Display Mode Keys
Following is a description of the display mode keys.
Reference Mode and Dynamic Mode Keys
The Reference (REF) and Dynamic 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. Following is a description of these two modes:
REF
MODE
REF MODE
This mode provides a maximum luminance of 120 cd/m2, continuously variable from 40 cd/m2.
DYNAMIC
MODE
DYNAMIC MODE
This mode provides a maximum luminance of 600 cd/m2, continuously variable from 40 cd/m2.
User-Loaded 3D LUT MODES
These two custom modes apply user‐loaded 3D look‐up tables (LUTs) to display the desired properties (for example, a film stock look, another display device, or other user‐specified properties). For information on loading custom LUTs, see Load LUTs.
CUSTOM 1
CUSTOM 2
Emulation Mode Keys
The emulation modes use LUTs that are preloaded on the system to duplicate the colorimetry of a specific display type. There are two emulation modes:
LCD
This mode emulates the properties of an LCD. PDP
This mode emulates the properties of a plasma display. 12
Dolby® Professional Reference Monitor Manual
Remote Control Basics
Operating Mode Keys
The operating modes provide access to the PRM‐4220 settings. Following is a description of the operating mode keys:
EDIT
This mode allows you to edit Reference mode, Dynamic mode, user‐loaded 3D LUT (Custom 1 and 2) mode, and LCD and PDP emulation mode parameters, as described in Section 2.3.
SYSTEM
This mode allows you to access and configure the PRM‐4220 global settings (those settings that are not accessible using the EDIT key). Typically, you specify the system settings at the beginning of a session, and these settings do not change during the session. For complete details on the SYSTEM key functions, see Section 2.4.
STATUS
The STATUS key displays the PRM‐4220 core operating parameters for the selected display mode. (See the example for Reference mode in Figure 2‐6.) It also provides access to a SMPTE timecode display.
2.2.3
Remote Control LCD
The Remote LCD provides screens and menus that allow you to access, edit, and configure many PRM‐4220 parameters. 2.2.4

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‐4220 parameters. You can configure many of these parameters using the Remote EDIT and SYSTEM menus. For more information on configuring these parameters, see Section 2.3 and Section 2.4. 2.2.6
Brightness and Contrast Controls
The BRIGHTNESS and CONTRAST control knobs (see Figure 2‐8) have dedicated blue LEDs. The respective LED illuminates when you turn a knob out of the default center detent position. The LED is off when a knob is in the center detent position
The BRIGHTNESS control sets the black level. It adds or subtracts an offset in the red, green, and blue channels. When adjusting this control, the black picture content should appear as true black on the PRM‐4220. After setting the brightness correctly, you should set the contrast for comfortable viewing brightness.
The CONTRAST control sets the white level. It applies a scale factor (gain) to the red, green, and blue channels. This affects the luminance (proportional to intensity) that the system reproduces for a full white input signal. You can lock the BRIGHTNESS and CONTRAST control knobs by pressing the B/C LOCK key in the Control section on the Remote (see Figure 2‐9). This lock prevents accidental changes to the settings. The B/C LOCK key illuminates in yellow when activated.
2.2.7
Ethernet Port
The Remote has one RJ45 port for connecting to the PRM‐4220 using a dedicated point‐to‐point network connection. The Remote communicates with the PRM‐4220 through this 10/100Base‐T connection using the provided Cat. 5e twisted‐pair cable. The transport and network layers are TCP/IP. The Remote IP address is statically configured at the factory; no user intervention is required for the Remote to communicate with the PRM‐4220.

Configuring Aspect Ratio and Scaling
To configure these parameters, press the SYSTEM key to activate the tab menu, then use the arrow keys (or the SYSTEM key) to move to the Aspect/Scaling tab. The Aspect Ratio and Scaling screen appears, as shown in Figure 2‐34. Figure 2‐34
Figure 2-34 Aspect Ratio and Scaling Screen
You can change the current Aspect Ratio and Scaling settings by pressing the arrow keys, and then pressing the ENTER key.
Aspect Ratio configures the screen image using asymmetrical scaling. This process performs a vertical stretch on input formats that have nonsquare pixels (to maintain the correct aspect ratio) and retains the horizontal resolution. For example, a standard definition source such as 720 × 480 has a horizontal‐to‐vertical pixel ratio of 3:2, but appears in a 4:3 aspect ratio. In this case, asymmetrical scaling converts the image to 720 × 540. If you set the Aspect Ratio to Auto, the system uses the aspect ratio defined by the video input. Scaling configures the screen image, adjusting the horizontal and vertical dimensions symmetrically: •
Pixel to Pixel maps input pixels to output pixels with no scaling. For example, a 1,280 × 720 source is mapped to the middle 67% of the 1,920 × 1,080 raster.
•
Fullscreen scales the source by the required scale factor to fill at least one dimension of the 1,920 × 1,080 raster. For example, the system scales up a 1,280 × 720 source by 1.5. For 2K sources that are not cropped by the 2K image position setting (see Figure 2‐39), the system scales down to 1,920 × 1,080. All other formats scale up.
•
Integer scales the source as close as possible to the full 1,920 × 1,080 raster using an integer scale factor. For example, the system scales up a 640 × 480 source by two, displaying a 1,280 × 960 active image in the center of the 1,920 × 1,080 raster.
•
Overscan is full‐screen mode plus a scale factor that decreases the size of the picture by 5%. •
Underscan is full‐screen mode plus a scale factor that increases the size of the picture by 5% and crops to 1,920 × 1,080.

Dolby® Professional Reference Monitor Manual
Configuring the System Parameters
Deinterlacing options:
•
Deinterlace converts interlaced video to progressive output using a motion‐adaptive deinterlacer. This process utilizes motion‐detection intelligence to adapt field combination with spatial filtering at the pixel level, which minimizes the undesirable side effects of traditional deinterlacers.
•
Direct Deinterlace converts interlaced video to progressive output using black‐line insertion. The system converts each field of the input source to a full frame and fills in undefined lines with black data. This operation performs no image signal processing.
•
Force PsF forces the PRM‐4220 to operate in progressive segmented frame (PsF) mode if the connected hardware does not send the correct PsF flag in the video bitstream.
3:2 Pull-down option:
•
3:2 Pull-down converts 59.94i and 60i input formats that originated from 23.98p and 24p, respectively (as detected by the system), back to their original progressive formats. This process constructs each frame of the progressive output from the appropriate odd and even fields of the input source.

Scale To Fit scales a 2K image horizontally and vertically so that the entire 2K image fits across the visible area of the 1,920 × 1,080 screen. Symmetrical black bars appear on the top and bottom of the screen. •
Pixel to Pixel displays a 2K image by centering it within the 1,920 × 1,080 active display screen. Typically, the system conceals 128 pixels on the left side and 128 pixels on the right side of the 2K image. However, you can use the adjustable slider to view any of the 128 pixels on the left and right side of the 2K image. 2.

Frequently Asked Questions
This appendix provides answers to frequently asked questions regarding the Dolby® Professional Reference Monitor (PRM‐4220). My CRT has a bias control. Why is there no bias control on the PRM-4220?
CRTs are analog devices, which require both gain and bias controls, as they are sensitive to small voltage offsets in the signal path. Typically, you adjust the gain control first to set the white point, and then set the bias control to adjust the black point. You then have to adjust gain a second time, as the first bias setting affects the first gain setting. Then you adjust the bias setting a second time. If performed correctly, the two gain and bias adjustments result in accurate white and black points.
The PRM‐4220 utilizes Dolby technologies that deliver extremely accurate, linear, and stable gray‐scale response after setting the white point using the gain controls. In addition, the PRM‐4220 provides white point and maximum luminance controls, which enable users to fine‐tune the monitor with a very high degree of precision.
As a result, users can set up the Dolby PRM‐4220 to closely match the response of a reference CRT monitor.
Can I display two images on the screen at the same time (split screen)?
Currently, this is not possible.
The latency between input and output is unacceptable for switching use.
All digital devices have a delay from input to output. To achieve reference‐level video quality, the PRM‐4220 incurs a slight additional delay. Currently, eliminating this latency is not possible.
Note that the PRM‐4220 has a unique audio sync pulse output. When you use this output together with a compatible audio delay line, this results in a higher degree of audio/video synchronization than any other monitor at all frame rates.
How do I log running hours?
CRT users need to log the number of hours the monitor is operational, so they can manage tube replacement (typically every 12–18 months). The PRM‐4220 LEDs are designed for more than 50,000 hours of operation, so there is no need to log use hours as you would a traditional CRT vacuum tube. I locked the monitor in the Utilities screen using a four-digit code, but I forgot
the code and cannot unlock the monitor.
Reboot the PRM‐4220 and the Remote. The lock mode is not persistent, but is removed when you reboot the PRM‐4220. Dolby® Professional Reference Monitor Manual

Frequently Asked Questions
Using the Remote, I cannot select the SDI B Link input, but I connected an
HD-SDI input to the SDI B input port.
Link B is active only when link A also has a valid input. Use link A for all single‐link input operations. When I start up the PRM-4220, the Remote freezes at the “Searching for
Monitor” screen.
Be sure the Remote Ethernet cable is connected firmly to both the Remote and the PRM‐4220 REMOTE port.
Be sure the Remote and the PRM‐4220 are running the same software version. If necessary, upgrade the software on the monitor and/or the Remote (see Software Upgrade).
How do I acquire the latest version of the PRM-4220 software?
You can obtain the latest software upgrade (.dlb file) from www.dolbycustomer.com. You will need to register and establish your user credentials.
How do I clean the PRM-4220 LCD screen?
We recommend an LCD‐compliant cleaning solution and a soft cloth.
Does the PRM-4220 have an air filter? if it does, how often do I need to replace
it and where can I purchase a replacement air filter?
