Incredible 20,000 lm of brightness 

Panasonic's unique quad-lamp system, with its new high-power UHM lamps, has helped to make the body extremely compact while providing an astounding 20,000 lm of brightness.


Dynamic Iris for a high 10,000:1 contrast ratio 

Panasonic's Dynamic Iris uses a scene-linking aperture mechanism to achieve a remarkable 10,000:1*1 contrast without lowering its high brightness. This helps to reproduce deeper, richer blacks, and provides images with more detailed textures.


Detail Clarity Processor 3 give natural clarity to even the finest details 

This unique Panasonic circuit optimizes the sharpness of each image, based on the super-high-, high-, medium-, and low-frequency components of the extracted image information. The resulting images have more natural, lifelike expression.


System Daylight View 2 for enhanced colour perception 

This unique Panasonic technology optimizes image quality to improve the colour perception of the projected image in bright rooms.

With a brightness of 20,000 lm, it provides highly comfortable viewing even in bright lighting, and allows viewers to concentrate easily on the images.


DICOM simulation mode*2 

This imaging mode is similar to DICOM part 14, which is a medical imaging standard. It reproduces X-ray images with remarkable clarity.


Active 3D projection capability 

The series is compatible with both passive and active 3D projection systems.  It combines with either a separate, external 100/120/144 Hz drive with IR emitter and active shutter glasses, or an active filter and passive glasses, for viewing 3D images.

  • Full 10-bit image processing
  • Progressive cinema scan (3:2 pulldown)
  • Dynamic sharpness control
  • Digital noise reduction
  • IP conversion
  • AI scene control2:2 pulldown mode

 Low TCO and environmentally friendly design

 The PT-DZ21 projectors lower the total cost of ownership (TCO) because they have a lamp replacement cycle of up to 2,000 hours*3. Their environmentally friendly design also includes a low power consumption of 2,300 W.

Lamp mode Brightness (lumens) Lamp replacement
cycle (hours)*
Quad 20,000 2,000
Triple 15,000 2,600
Dual 10,000 4,000
Single 5,000 8,000



Four lamp system enable stable, extended operation 

The four-lamp system allows the projector to keep working even if a lamp should fail. The Lamp Relay mode also operates the lamps alternately to enable 24/7 projection. Quad, Triple, Dual and Single Lamp modes can be used.


Easy lamp replacement 

For easier maintenance, you can replace the lamp from the rear. This makes it easy to replace a lamp while the projector is still in the mounting bracket or dual stacked.


Liquid cooling system attains a high level of reliability 

This new liquid cooling system directly cools the DLP™ chip to improve performance and enable operation up to 45 °C (113 °F)*4.  It allows quiet (49 dB) and versatile use while stabilizing performance.  It also helps to make the body compact. And the system is hermetically sealed, so you don't need to replenish the liquid.


Eco filter that needs no maintenance for up to 12,000 hours*5 

The Eco Filter has an electrostatic Micro Cut Filter that collects minute dust particles with an ion effect. It combines with the dust-resistant cabinet to enable long-term use even under harsh conditions. Its maintenance cycle of up to 12,000 hours reduces hassle, and the environmental design lets you wash the filter with water and reuse it.*6


Flexible installation 

The wide adjustment range of the powered horizontal/vertical lens shift function can be easily adjusted with the remote control.

The unit can also be rotated 360° vertically*7, to accommodate various installation conditions. The lens-centered design contributes to easy installation.


Multi unit brightness control


This function automatically corrects the brightness fluctuations that occur over time in the individual projectors of a multi-screen system. Up to eight projectors can be controlled by connecting to each other via a hub, and this can be increased to a maximum of 2,048 projectors by using "Multi Projector Monitoring & Control Software Ver. 2.7."


Multi Screen Support System seamlessly conneccts multiple screens 

The Multi-Screen Support System optimally adjusts multiple screens: Edge blending, colour matching.

Edge Blending
The edges of adjacent screens can be blended and their luminance controlled.

Colour Matching
This function corrects for slight variations in the colour reproduction range of individual projectors.

Multi-Screen Processor
The PT-DZ21 can project large, multi-screen images without any additional equipment. Up to 100 units (10 x 10) can be edge-blended at a time.


Geometric adjustment for specially shaped screens 

This function adjusts the image for projection onto spherical, cylindrical and other specially shaped screens. You can make the adjustment easily using only the remote control, with no external equipment needed.


Optional upgrade kit (ET-UK20) featuring Geometry Manager Pro 

The new Geometry Manager Pro software included in the optional upgrade kit ET-UK20 supports Colour Matching and Edge Blending for multi-projector setups (max. 32 units). It also allows creative masking using four lines or bitmap data. And its flexible and complex geometric adjustment capability suits a wide variety of screen shapes.


Multiple terminals 

The PT-DZ21 has an array of terminals, including DVI-D, HDMI and two RGB inputs.  The PT-DZ21K features a 3D-ready HD/SD-SDI input and 3D sync terminals to connect an emitter for 3D projection.


Multi Projector Monitoring and Control Software Ver. 2.7 

Panasonic's original Multi Projector Monitoring & Control Software Ver. 2.7 freeware lets you control and monitor multiple projectors at the same time over a wired LAN. If a problem occurs, an alarm message is sent to the monitoring/controlling PC. The terminal connection area is LED illuminated, and a backlight is provided for the control panel buttons, ensuring smooth and easy operation in the dark.

  • *8 Up to a total of ±55° during simultaneous horizontal and vertical correction.
  • *9 With legs at shortest position.
  • *10 Average value. May differ depending on the actual unit.
  • *11 The operating temperature range is 0 °C to 40 °C (32 °F to 104 °F) when the fan control is set to HIGH ALTITUDE MODE (for altitudes from 1,400 m to 2,700 m (4,593 ft to 8,858 ft) above sea level). When the projector is used with the ET-SFR510 Smoke Cut Filter, the operating temperature range is 0 °C to 35 °C (32 °F to 95 °F), and the projector cannot be used in places at high altitude.
1. Do not install the projector in locations that are subject to excessive water, humidity, steam, or oily smoke. Doing so may result in fire, malfunction, or electric shock.
2. The projector uses a high-voltage mercury lamp that contains high internal pressure. This lamp may break, emitting a large sound, or fail to illuminate, due to impact or extended use.
3. The projector uses of high-wattage lamp that becomes very hot during operation. Please observe the following precautions:
• Never place objects on top of the projector while it is operation.
• Make sure there is an unobstructed space of 500 mm (19-11/16 inches) or more around the projector's exhaust openings.
• Do not stack projector units directly on top of one another for the purpose of multiple (stacked) projection. When stacking projector units, be sure to provide the amount of space indicated between them. These space requirements also apply to installation where only one projector unit is operating at one time and the other unit is used as a backup.
• If the projector is placed in a box or enclosure, temperature of the air surrounding the projector must be between 0 °C (32 °F) and 35 °C ( 95 °F). Also make sure the projector's intake and exhaust openings are not blocked. Take particular care to ensure that hot air from the exhaust openings is not sucked into the intake.
4. If the projector is to be operated continuously 24 hours a day / 7 days a week, use the multi-lamp optical system's alternating lamp operation (lamp changer) function. The projector can be operated continuously 24 hours a day / 7 days a week in four-lamp operation mode, but it will automatically operate with three lamps for 8 hours of the 24 hours / 7 days.
5. The lamp replacement cycle duration becomes shorter if the projector is operated repeatedly for short periods.
• The length of time that it takes for the lamp to break or fail to illuminate varies greatly depending on individual lamp characteristics and usage conditions.
• The brightness of the lamp will gradually decrease with use.
6. Because the ET-D75LE50 is a fixed short-throw lens, the lens shift function cannot be used with it.
7. Due to natural characteristics of lamps, screen brightness may vary (flicker). This is not an indication of faulty lamp performance.
