High brightness and high picture quality
Wide screen and high-power 5,500-lm brightness (PT-DW5100/DW5100L)
The PT-DW5100/DW5100L offers a full 5,500 lumens of brightness and WXGA wide-screen projection. A newly developed AC lamp, a more efficient reflector and a synthetic mirror produce crisp, sharp images even when projecting images with a wide aspect ratio in ordinary daytime lighting.
The PT-D5700/D5700L offer full 6,000 lumens of brightness, thanks to the newly developed AC lamp and more efficient reflectors and synthetic mirror. This enables crisp, sharp images even when projecting in a classroom, meeting room, or other location with ordinary daytime lighting.
Ultra bright 4,000-lm (PT-D4000)
The PT-D4000 offers 4,000 lumens of brightness, thanks to the newly developed AC lamp and more efficient reflectors and synthetic mirror. Real-life images are also produced in rooms with the lights turned on.
System daylight view
The system daylight view function uses an image processing circuit to compensate for the loss of color saturation that occurs when light reflects onto the screen from bright surroundings. It is especially effective for producing crisp, sharp images in dark portions containing gradation. The function can be adjusted in three steps.
Vivid color (DW5100/DW5100L/D5700/D5700L)
A unique control technology is used to maximize the color segment areas of the color wheel. Compared to conventional projectors, the brightness of each color is increased by an average of about 15%. This results in sharper, clearer color reproduction.
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.
New IP conversion circuit
The PT-DW5100/DW5100L/D5700/D5700L/D4000 features a new IP conversion circuit that produces more detailed images than our previous models.
More effective noise reduction
Images are noticeably clearer, thanks to higher-performance frame noise reduction, which lowers image graininess, and improved MPEG noise reduction, which suppresses the block noise and mosquito noise that are common in fast-action scenes.
Progressive cinema scan (3/2 Pulldown)
This interlace/progressive conversion technology automatically detects when the input signal is derived from filmed material and selects the optimum progressive processing method to assure faithful reproduction of the original image.
Dynamic sharpness control
The dynamic sharpness control circuit adjusts the video signal waveforms based on the difference in brightness of adjacent pixels for a sharp, clear picture that is relatively unaffected by signal noise.
3D color management system
Compensation provides optimal levels of color saturation, hue, and brightness that were not possible with conventional projectors. Colors approach those of the original image, even on large-screen displays.
