Explore New Possibilities with the World’s Smallest

and Lightest 20,000-lumen-class 4K+ Projector

The Panasonic PT-RZ21KU gives staging innovators an edge where the limits of projection are routinely tested. As the world’s smallest and lightest 20,000-lm-class laser projector, the PT-RZ21K can be easily handled by just two people
and realizes 20,000 hours of maintenance-free projection thanks to hermetically sealed optics and filterless heat-pipe-based cooling. And now, Panasonic unveils the groundbreaking PT-RZ21K , the world’s smallest and lightest 20,000-lm-class
WUXGA laser projector. It shares the same maintenance-free design while delivering unassailable WUXGA image-quality. Together with a lens lineup that’s compatible with all large-venue projectors, the PT-RZ21K makes world-class projection smooth
and cost-effective.

Key features

• Laser 3-chip DLP, 21,000 center lumens, WUXGA


• Lamp-free laser projection with dust resistant liquid cooling system with 20,000 hours of free maintenance


• 240Hz high frame rate for superb and sharp motion pictures and a 20,000:1 contrast ratio


• Geometric Manager Pro, colour matching and multiple screens edge blending, Exchangeable lens, 24/7 operation, geometric adjustment, 360° flexible installation

Supports BT.2020 Emulation and HDR

The PT-RZ21K has emulation for BT.2020. It reproduces a wider color gamut than conventional standards. Additionally, they support HDR (High Dynamic Range). Image reproduction is stunning, from deepest black to sparkling bright highlights

New Noise-Reduction Function Enhances HDR Content

Noise in dark areas of conventional images—emphasized when inferior equipment is used to project HDR video—is erased with Panasonic’s newest noise-reduction technology. These new projectors effectively eliminate picture noise in dark
areas without decreasing highlight brightness, while the PT-RZ21K lets viewers experience spectacular HDR video unspoiled by noisy blacks

Innovating Class-beating Picture Quality in Permanent or Staging Installations

Peak Optimization for Mapping and Daylight Projection

This premium technology stops pictures washing out in bright light and assures dramatic impact for mapping and multi-projector applications. It uses sensor information to correct sharpness, gamma curves, and colors to suit on-site conditions.

Contrast and Shutter Sync Functions

Contrast Sync allows Dynamic Contrast Control to be synchronized for consistent picture quality across multiple screens. Shutter Sync, meanwhile, synchronizes shutter on/off timing.

90 % Brightness Uniformity

SOLID SHINE Laser delivers superior brightness uniformity thanks to accurate white balance control. Brightness uniformity is greater than 90 % when measured at screen corners, edges, and center.

Multi-unit Brightness and Color Control

Sensors detect color and brightness apparent on screen. Projectors automatically calibrate for a uniform multi-screen image, adding a layer of convenience and cost saving both in short-term and long-term events.

Lower TCO in NORMAL and ECO Modes

The PT-RZ21K is engineered to operate for 20,000 hours without maintenance, with no filter or light-source replacement required even in challenging operating conditions. In applications where maximum brightness isn’t necessary, such as in
surveillance, control, or simulation rooms, or in darkened museums or planetariums, ECO Mode extends continuous operation out to about 24,000 hours. In this mode, color consistency is maintained with a flatter brightness ramp preserving high picture
quality for longer while reducing total cost of ownership.

Free 360-degree Orientation

SOLID SHINE Laser enables free 360-degree installation through any axis. Together with powered lens shift and wide range of optional lenses, the PT-RZ21K projectors can be installed in any orientation without picture distortion.

Geometry Manager Pro Software and Upgrade Kits

Geo software expands image adjustment and simplifies multi-screen setup. The free software performs color matching, edge blending, and other functions via network. Optional upgrades and plug-ins further streamline and automate setup.

Quick Start and Quick Off

No warm-up or cool-down period is required when operating PT-RZ21K projectors. Images appear almost instantly, and the projector can be switched on and off whenever desired.

Over-Engineered for Consistently Bright, Dependable, and Efficient Projection

Filterless Laser Design Delivers 20,000-hour Maintenance-free Operation

The Panasonic PT-RZ21K is the world’s first 20,000-lm-class laser projector lineup to eliminate air filters from its design, enabling maintenance-free operation for 20,000 hours. This is achieved with hermetically sealed optics and unique
heat-pipe-based cooling with one-way airflow. The projector can operate continuously for long periods without regular maintenance, saving operators time and money. With no filters to replace and controlled brightness ramp, the PT-RZ21K Series
saves you real money

Dual-Drive Laser with Dustproof Optics

These projectors are virtually dustproof to preserve the stunning brightness delivered by dual solid-state laser modules, which feature redundancy circuitry. Hermetically sealed optical block helps prevent failures and extends brightness. Exceeding the
toughest standards for operation in dusty environments, these projectors stay brighter for longer.

Backup Input Guarantees Picture Display

Projectors switch instantly to a backup input*3should the primary signal be disrupted, so display is maintained in situations where projection must not be interrupted. No screen-blanking occurs during backup input switching.

Supports Art-Net DMX, Crestron Connected™, and PJLink

Art-Net DMX protocol for lighting management enables connection with lighting consoles for added functionality and control options. Crestron Connected™ and PJLink™ ( Class 2) streamline integration into existing AV infrastructure

Multi-screen Support System

This system optimizes multiple screens with edge blending, color matching, and digital image enlargement functions

• Edge Blending: Edges of adjacent screens can be blended and their luminance controlled


• Color Matching: Corrects color reproduction variations of each projector via PC control software.


• Digital Image Enlarging: Digital zoom up to 10x (H/V)*5, and up to 100 units ( 10 x 10 ) can be edge-blended to create large multi-screen images.

Built-in Geometric Adjustment

Geometric Adjustment adapts the image for projection onto specially shaped screens with fine-tuning available via remote control. With 4-Corner Adjustment, each corner can be independently adjusted. Screen aspect may be kept on when correcting curves,
or to make effective use of the screen area, aspect preservation can be turned off.

Frame Delay Adjustment for Multi-projection

Frame synchronization may be fine-tuned with the PT-RZ21K Series. Users can adjust frame delay in 1/100th millisecond increments for perfectly synchronized video. This improves multi-projection compatibility with projectors such as the PT-RZ21K

Projector Management and Control Flexibility

Single-Cable DIGITAL LINK Video and Control Connection

DIGITAL LINK transmits video and control commands through a single CAT 5e or higher STP cable for distances of up to 150 m (492 ft) for Full HD video and 50 m (164 ft) for 4K*1 video*2. Optional DIGITAL LINK Switcher further simplifies installation and
reduces cabling and associated costs.

Multi Monitoring & Control Software

Panasonic Multi Monitoring & Control Software supports up to 2,048 devices over LAN and features system map visualization or auto-search of devices to be registered. The free software is available with Early Warning functions (automatic free 90-day
trial available). These advanced functions enable real-time monitoring, abnormality detection, and notification before servicing is required. Administrators can achieve seamless control and real-time monitoring while preventing potential problems,
saving time, and enhancing system reliability.
