{"product_id":"lsd400w","title":"ViewSonic LSD400W – 400-Inch Capable WUXGA Laser Projection System","description":"\u003ch2\u003eProduct Overview\u003c\/h2\u003e\u003cp\u003eThe ViewSonic LSD400W is a 4,000 ANSI lumen WXGA DLP laser projector built for classrooms and conference rooms where reliable daily operation and low maintenance are the primary requirements. Laser phosphor technology eliminates lamp replacements and uses up to 49% less power than traditional lamp projectors, reducing both maintenance and energy costs over the unit's 30,000-hour lifespan. A 0.65\" DLP chip and IP6X-rated sealed engine deliver consistent image quality with no filter to clean or replace. At 32% smaller than previous models, the LSD400W installs more easily in space-constrained rooms.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe LSD400W is a straightforward commercial laser projector for rooms that need reliable performance day after day. At 4,000 ANSI lumens, it maintains readable images in well-lit classrooms and meeting rooms without requiring the lights to be fully dimmed. The 0.65\" DLP chip and WXGA (1280x800) resolution produce crisp text and clear images at screen sizes from 30 to 300 inches, with a 3,000,000:1 dynamic contrast ratio keeping content sharp regardless of the content type.\u003c\/p\u003e\u003cp\u003eThe IP6X-rated sealed engine blocks dust without requiring a filter, eliminating one of the most common maintenance tasks for installation projectors in high-use environments. Firmware updates can be applied via USB without a service call, minimizing downtime. The projector supports 360° projection and portrait mode for ceiling, floor, and angled installations, and a 1.1x optical zoom with H\/V keystone and 4-corner adjustment handles rooms where placement is less than ideal. With instant on\/off and no warm-up period, the LSD400W is ready the moment a session starts. HDMI 1.4 inputs and RS232 control cover standard commercial AV connectivity needs. A built-in 3W speaker provides basic audio capability.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4,000 ANSI Lumens\u003c\/strong\u003e — Holds up in ambient-light classrooms and conference rooms without requiring full blackout.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e30,000-Hour Laser Light Source\u003c\/strong\u003e — No lamp replacements;

This keeps the projector current with minimal disruption to daily use.\u003c\/dd\u003e\n\u003cdt\u003eWhat is the throw ratio, and will it work in a standard classroom?\u003c\/dt\u003e\n\u003cdd\u003eThe throw ratio is 1.544 to 1.72. To project a 100-inch image, the projector needs to be placed approximately 3.33 meters from the screen. This is a standard-throw ratio suited for typical classroom and conference room ceiling mounts.\u003c\/dd\u003e\n\u003cdt\u003eDoes the LSD400W support network control?\u003c\/dt\u003e\n\u003cdd\u003eThe LSD400W includes RS232 serial control. It does not include an Ethernet\/LAN port. For LAN-based remote management, the LSD500HD would be the appropriate model.\u003c\/dd\u003e\n\u003cdt\u003eWhat resolution does the LSD400W produce?\u003c\/dt\u003e\n\u003cdd\u003eThe native resolution is WXGA (1280x800) at a 16:10 aspect ratio. This matches the native format of most commercial presentation sources and widescreen classroom content.\u003c\/dd\u003e\n\u003cdt\u003eHow does the laser light source reduce total cost of ownership?\u003c\/dt\u003e\n\u003cdd\u003eThe laser light source runs up to 30,000 hours with no lamp replacements and uses up to 49% less power than lamp projectors.
