The ViewSonic LS740HD is a high-performance, laser-powered projector engineered for demanding environments — from large conference rooms and classrooms to auditoriums and event spaces. With a powerful 5,000 ANSI-lumen output, it delivers bright, vivid, and eye-catching images even under ambient light, making it well-suited for daytime use or venues without full light control. Its native Full HD (1920×1080) resolution ensures crisp, detailed visuals, whether you're projecting presentations, videos, charts, or high-resolution photos.
Because it uses a modern laser-phosphor light source rather than a traditional lamp, LS740HD offers long life and low maintenance: around 20,000 hours in standard mode, and up to 30,000 hours in economy mode. This makes it a reliable, cost-effective solution for heavy use and continuous operation. The projector supports a large screen size range — from 30″ up to 300″ — giving you flexibility to adapt to small meeting rooms as well as large halls or auditoriums.
Thanks to its manual 1.3× zoom lens, 1.13–1.47 throw ratio, and keystone adjustment (vertical and horizontal), installation and setup are flexible and forgiving. Two HDMI inputs, a 3.5 mm audio-out, USB power/service, and RS-232 control ensure broad compatibility with laptops, streaming devices, media players, and control systems. A built-in 15 W mono speaker provides basic audio for meetings or classes without requiring external sound equipment. Compact dimensions and lightweight build make mounting or repositioning easier, while the sealed optical engine reduces dust ingress and extends longevity.
