High Brightness with High-Power AC Lamp: The high-efficiency light convergence technology and the color wheel work together to achieve the high brightness of 6,000 lm for the PT-DW640. Clear, crisp images are reproduced even in bright rooms
RGB Booster Significantly Improves Color Reproduction: The RGB Booster achieves high image quality with levels of color reproduction and brightness that make each color stand out
Vivid Color Control: This unique control technology optimizes the use of the color segment areas of the color wheel. It increases the brightness of each RGB color by minimizing the unallocated portions between the colors, to achieve truly vivid coloring
Lamp Modulation Drive System: With the advanced lamp modulation technology, the projector is able to control the lamp intensity for each of the red, green, blue and white segments of the color wheel separately
Detail Clarity Processor Brings Depth and Clarity to Details: This advanced image-processing circuit analyzes the video signal frequency range for each scene by extracting data on the distribution of high, mid and low-frequency components and brings out fine details accordingly
System Daylight View 2 for Enhanced Color Perception: Image details are less clear when a projector is used in a room with the lights on. Panasonic's System Daylight View 2 improves brightness perception by adjusting sharpness, gamma curves and color corrections
DICOM Simulation Mode: This imaging mode is similar to DICOM part 14, which is a medical imaging standard. It reproduces X-ray images with remarkable clarity
Rec. 709 Mode for HDTV Projection: Optimal color reproduction can be achieved by selecting this mode, compliant with ITU-R Recommendation BT.709, when images from an HDTV source are projected
Full 10-Bit Picture Processing: The use of a full 10-bit image processing system provides smooth tonal expression. For example, skin tones appear natural and true to life
Eco Filter that Needs No Maintenance for up to 12,000 Hours: The original Eco Filter consists of two Micro Cut Filters (electrostatic filters), a pre-filter and a main filter, which use an ion effect to collect extremely small dust particles
Dual-Lamp System Prevents Image Interruptions: 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
Liquid Cooling System Attains a High Level of Reliability: Panasonic's unique liquid cooling system directly cools the DLP chip to improve performance and enable operation up to 45deg.C (113deg.F). It also contributes to realizing the compact body
Flexible Installation: 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
A Wide Range of Optional Lenses: Choose from a wide lineup of optional lenses for your system, including short-throw, long-throw . The lenses attach and detach with one-touch ease
Lens-centered Design: A lens-centered, symmetrical design provides ease of installation, eliminating the need for any special considerations when planning the installation site
Easy Replacement of Filter and Lamp: An Eco Filter is replaced from the side and lamps are replaced from the back panel. Both of them are replaced very easily even after the projector is installed on the ceiling
Side-by-Side Function: The PT-DW640 can simultaneously display images from two sources onto a single screen. For example, you can display a PC image on the left and a video image on the right
Versatile System Configurations: A serial input/output terminal that allows remote operation from a PC, similar to that of a wireless remote control and a remote terminal for input switching by contact control and standby ON/OFF operation also make it possible to configure a remote operation system
Crestron RoomView and AMX Device Discovery: The LAN terminal allows a computer connected to the network to use Crestron RoomView application software to manage and control system devices. Besides, the AMX Device Discovery technology is built in the PT-DZ680 Series projectors
Wireless Remote Control with a Maximum Operating Range of 30 m (98 ft): Wireless Remote Control provides greater convenience for large conference rooms, lecture halls and gymnasiums with large audiences. Also, two signal transmission ports are provided to enable a large operating area
