Panasonic PT-DZ870 Full HD DLP Projector Bright 8,500 Lumens From A Compact Body A unique dual-lamp drive system has helped to make the body compact, while two newly PT-DZ870 with an ultra short throw lens DLE030 PT-DZ870 with an ultra short throw lens DLE030 developed, high-output, 420 W lamps provide high brightness of 8,500 lm. Dynamic Iris for 10,000:1 Contrast ratio Panasonic’s Dynamic Iris uses a scene-linking aperture mechanism to achieve a remarkable 10,000:1* contrast without lowering its high brightness. This helps to reproduce deeper, richer blacks, and provides images with more detailed textures. Dynamic Iris Booster Panasonic’s RGB Booster achieves high image quality with levels of color reproduction and brightness that make each color stand out. It combines Panasonic’s proprietary Vivid Color Control technology with a Lamp Modulation Drive System for a 1-chip DLP™ projector that produces bright and vivid colors. This has been further advanced in the PT-DZ870 Series with the development of the Dynamic RGB Booster. Images are analyzed frame by frame, and scene-linking and realtime modulation are used to achieve high brightness and vivid color reproduction.
