ViewSonic LS740W: 5000 ANSI Lumens WXGA Laser Lamp-Free Projector

Meet the ViewSonic LS740W, a high-brightness, lamp-free projector built for modern presentations in any setting. Powered by laser phosphor technology, this model delivers up to 5,000 ANSI lumens of brightness to reveal crisp, vibrant images even in rooms with ambient light. The WXGA native resolution (1280x800) provides comfortable clarity for slides, spreadsheets, and multimedia content, ensuring your message comes through with precision. With a 1.3x optical zoom, you can frame your content confidently without repositioning the projector, while horizontal and vertical keystone correction helps you achieve a perfectly rectangular image from a variety of installation angles. Four-corner adjustment further refines image geometry for impeccably aligned projections on screens, walls, or projection surfaces. The LS740W is designed to minimize maintenance and downtime thanks to its laser lamp-free design, which eliminates lamp replacements and reduces total cost of ownership over the projector’s long life. Whether you’re equipping a classroom, conference room, or event space, this projector offers dependable performance, consistent color, and a straightforward setup that lets you focus on delivering compelling content rather than technical hassles.
