Description

The ViewSonic LSD401HD is a 1080p addition to the lamp-free Luminous Superior Series, aimed at boardrooms, lecture halls and public spaces. Third-generation laser phosphor technology delivers 4,000 ANSI Lumens with up to 30,000 hours of light-source life, and centralised LAN control certified for Crestron and Q-SYS (and compatible with AMX, PJ Link, ATEN and Extron) simplifies fleet management.

A 0.65" 1080p DMD chip provides native 1920x1080 resolution with a 3,000,000:1 contrast ratio, and a sealed, filter-free optical engine keeps colour performance consistent over time. Unlike the fixed-zoom LSD400HD, the LSD401HD adds a wider 1.3x optical zoom and a 1.13-1.47 throw ratio range for easier positioning, alongside H/V keystone with 4-corner correction and 360-degree/portrait projection. HDMI 2.0b with HDCP 2.2 accepts 4K UHD/HDR10/HLG sources at up to 60Hz, and a dedicated Golf colour mode suits simulator installs.

A 15W built-in speaker, dual HDMI inputs, RJ45 LAN and a 5V/1.5A USB-A output for ViewSonic's ViewShare wireless dongle complete the connectivity, with USB-based firmware updates for on-site servicing.

Planning from a real wall? Use the projector screen size calculator to upload a photo, preview the image to scale and find projectors that fit within your maximum available space. Replacing an existing projector? The projector replacement calculator checks whether this lens covers the ratio your current mount needs.

Distances are lens-to-screen, calculated from the manufacturer's stated throw ratio; allow for lens shift and mounting hardware. Always confirm against the manufacturer's installation guide before fixing mounts.
