The high-efficiency light convergence technology and the color wheel work together to achieve the high brightness of 6,000 lm for the PT-DW640ULS. Clear, crisp images are reproduced even in bright rooms.
The Dual-Lamp System eliminates the need to interrupt a presentation if a lamp should burn out (in dual-lamp operation mode). The Lamp Relay mode also operates the lamps alternately to enable 24/7 projector operation.
Panasonic's unique liquid cooling system directly cools the DLP™ chip to improve performance and enable operation up to 45°C (113°F). This allows use in a wider variety of environments, while stabilizing performance and keeping the unit quiet even in harsh conditions. It also contributes to realizing the compact body. Plus, Panasonic’s liquid cooling system is hermetically sealed, so you don’t need to replenish the liquid.
The wide adjustment range of the powered horizontal/vertical lens shift function assures convenience and versatility during installation. It lets you easily make adjustments with the remote control. The unit can also be rotated 360 degrees vertically. This means you can install it at any angle you want, to accommodate different installation conditions.
Choose from a wide lineup of optional lenses for your system, including short-throw, long-throw zoom and fixed-throw lenses for rear projection use. The additional lenses make it easy to adapt your projector to the installation site. The lenses attach and detach with one-touch ease.
The Multi-Screen Support System optimally adjusts multiple screens: Edge blending, color matching and multi-screen processor.
Simultaneously display images from two sources onto a single screen with the Side-By-Side function. For example, you can display a PC image on the left and a video image on the right. Taking advantage of the wide-screen projection, this function gives you a host of new application possibilities to explore.
Remotely operate projectors and check their status with a computer connected through a wired LAN system. An e-mail messaging function can also notify you when a lamp needs replacement, and indicate the overall projector status. In addition, Multi Projector Monitoring and Control Software is available for monitoring and controlling multiple Panasonic projectors from a single PC.
