The ViewSonic LSC521WU is a professional-grade WUXGA laser projector designed for high-impact presentations in corporate, education, and large venue settings. With 5,200 ANSI lumens of brightness and native 1920 x 1200 resolution, it produces ultra-sharp, vivid visuals that remain clear even in bright environments.
Built on 3LCD technology with a third-generation laser phosphor light engine, this projector offers excellent color performance and long-term reliability. Its laser light source is rated for up to 20,000 hours in standard use and up to 30,000 hours in Eco mode, minimizing maintenance and operating costs.
The projector supports a wide 21:9 aspect ratio—ideal for modern collaboration platforms—and includes vertical lens shift, keystone correction, and a 1.6x optical zoom for flexible installation. Whether ceiling-mounted or positioned on a shelf, it adapts easily to a variety of spaces.
It also features broad connectivity with HDMI, HDBaseT, VGA, composite video, and LAN/RS232 control, making integration into existing AV systems straightforward. A built-in 16W speaker adds an extra level of convenience for small to medium-sized meeting spaces.
