Product Overview

The ViewSonic® LSD400HD-ST is a high-brightness, lamp-free 1080p projector designed for modern professional and educational environments. Utilizing advanced 3rd generation laser phosphor technology, it delivers 4,000 ANSI Lumens of brightness for up to 30,000 hours, eliminating the need for frequent bulb changes and the maintenance downtime associated with traditional lamp projectors. This sustainable "fit and forget" solution is significantly more energy-efficient, reducing power usage by up to 49%. With its 0.5 short throw lens, the LSD400HD-ST projects massive, shadow-free images in tight spaces, while the IP6X sealed optical engine and high-contrast 0.65" DMD chip ensure durable, professional-grade performance. Featuring 360° projection, portrait mode, and centralized LAN control, it offers the installation flexibility required for everything from corporate boardrooms to creative digital signage.

Overview

Big Images in Small Spaces

Short throw technology projects a 100" image from just 1.1 meters away, making large-format projection possible in spaces where a standard-throw projector wouldn't fit. That opens up conference rooms, classrooms, golf simulators and other tight spaces that a longer throw distance would rule out. Close-range positioning also keeps presenters out of the light path, so shadows and eye glare aren't a problem.

Stays Visible in Ambient Light

At 4,000 ANSI lumens, this projector holds up in rooms with some ambient light, delivering clean, color-accurate images without losing detail. In dimmed conference rooms and training spaces, images stay vivid without touching the light switch.

Manage Every Unite Remotely

Certified for Crestron and Q-SYS, and compatible with AMX, PJ Link, ATEN and Extron, this projector integrates directly into professional AV control systems. IT managers can monitor and manage units remotely over LAN without needing to be on-site.

Lower Costs, Longer Lifespan

The latest laser phosphor technology delivers up to 30,000 hours of runtime with zero lamp replacements. That means less scheduled maintenance, lower long-term operating costs and a mercury-free light source that's better for the environment.

Crisp Text and Deeper Contrast

A 0.65" DMD chip produces deep blacks, bright whites and crisp text at any size, with strong native contrast that keeps images sharp and readable across the full 3,000,000:1 dynamic contrast ratio.

No Warm-Up, No Wait

This projector powers on to full brightness the moment it turns on. That means there's no warm-up period or cooldown required. In commercial environments where every minute counts, that kind of responsiveness makes a real difference.

Richer Color and Deeper Contrast

HDR10 and HLG support deliver richer contrast and more accurate color at full 1080p output. Brighter highlights, deeper shadows and a wider color range bring every frame to life in cinema-quality presentations and immersive simulation environments alike.

Golf Mode with Enhanced Color

A dedicated Golf Mode fine-tunes color output to boost greens and blues. Fairways, water hazards and course details look as true-to-life on screen as they do in person, making the LSD400HD-ST a natural fit for golf simulation venues and training facilities.

360° Projection and Portrait Mode

The LSD400HD-ST rotates to any angle so the space dictates the setup, not the other way around. Ceiling mounts, floor projections and portrait mode all work without compromising image quality, opening up possibilities that a fixed display simply can't match.

Effortless Image Shaping

Horizontal and vertical keystone correction with 4-corner adjustment keep the image square and proportioned even when placement isn't ideal. The projector adapts to the room rather than requiring the room to adapt to it.

Built for 24/7 Operation

Advanced cooling and a sealed engine keep the LSD400HD-ST running day and night in demanding commercial environments. Venues, museums and public spaces can count on consistent performance without scheduled downtime or interruption.

Crisp, Built-In Audio

A built-in 15W speaker handles clear audio for presentations and public displays without requiring a separate sound system. Setup stays simpler and cabling stays minimal from day one.
