ViewSonic LSD400HD-ST 4, 000 ANSI lumens, 0.65" 1080p DLP Laser Projector

Product Overview

The ViewSonic LSD400HD-ST is a 4,000 ANSI lumen 1080p short-throw DLP laser projector designed for professional AV environments where installation depth is constrained. Utilizing a 0.65" DMD chip and 3rd-generation laser phosphor technology, it delivers full HD images from a 0.5 throw ratio — projecting a 100" screen from just 3.6 feet — while maintaining a 30,000-hour maintenance-free light source. Its IP6X-rated sealed optical engine and support for 360° projection, portrait mode, and LAN control make it a practical choice for corporate boardrooms, training rooms, and digital signage installations.

Product Description

The LSD400HD-ST addresses a common integration challenge: achieving large-screen 1080p projection in rooms where throw distance is limited by architectural constraints. At a 0.5:1 throw ratio, it can fill a 100" screen from approximately 1.1 meters (3.6 feet), eliminating presenter shadow and hotspot issues common with standard-throw units mounted close to the screen. The 0.65" DMD chip delivers high-contrast DLP performance at full HD resolution. 3rd-generation laser phosphor technology rated at 30,000 hours removes the lamp replacement variable from service contracts and maintenance schedules, making it a strong TCO argument for managed AV environments. The IP6X-sealed optical engine protects against dust ingress for reliable 24/7 operation in commercial spaces. Power consumption is reduced by up to 49% compared to equivalent lamp-based projectors. The unit supports 360° projection including 90° portrait mode for vertically-oriented digital signage, and H/V keystone correction with 4-corner adjustment covers off-axis setups. Centralized LAN control supports PJ-Link and RS-232 integration for enterprise AV management. The mercury-free design simplifies disposal compliance for institutional buyers.
