The PT-RZ770 7200-Lumen WUXGA DLP Projector from Panasonic features a solid-state laser light source and full-spectrum color wheel that boosts color without sacrificing brightness. Because the PT-RZ770 is powered by SOLID SHINE laser technology, you can turn the projector on and off any time you like. With Quick Start mode, projection begins in about one second. The projector also features a Quartet Color Harmonizer wheel mechanism that captures a wider color space than comparable projectors, allowing the color white to be reproduced realistically on-screen. The PT-RZ770 includes a lens with a 1.7 to 2.4:1 throw ratio that provides a 50 to 600″ screen size. This dustproof projector, with no lamps or filters to replace, provides 20,000 hours of maintenance-free projection with consistent picture quality.
