Four-Lamp System Enables 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 alter-
nately 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).*

It allows quiet
(49 dB) and versatile use while stabilizing perfor-
mance. 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
*

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 environ-
mental design lets you
wash the filter with water
and reuse it.*

, to accommodate various installation
conditions. The lens-centered design contributes
to easy installation.
Multi-Unit Brightness Control
This function automatically corrects the bright-
ness fluctuations that occur over time in the
individual projectors of a multi-screen system. Up
to eight projectors can be controlled by connect-
ing to each other via a hub, and this can be
increased to a maximum of 2,048 projectors by
using “Multi Projector Monitoring & Control Soft-
ware Ver. 2.7.”
Multi-Screen Support System Seamlessly
Connects Multiple Screens
•
Edge Blending
: The edges of adjacent screens
can be blended and their luminance controlled.
•
Color Matching
: This function corrects for slight
variations in the color reproduction range of indi-
vidual projectors. The PC software assures easy,
accurate control.
•
Multi-Screen Processor
: The PT-DZ21K Series
can project large, multi-screen images without
any additional equipment. Up to 100 units (10 ×
10) can be edge-blended at a time.
The Panasonic PT-DZ21K Series of flagship models feature
breathtakingly beautiful images and reliable operation.
A host of creative capabilities meet the
projection needs of highly critical professionals.

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.

When washing with water, please follow the procedures listed in the operating instructions.
Also, we recommend replacing the filter with a new one after it has been washed and reused twice. If the filter is not sufficiently clean after washing, replace it with a new one.
