ViewSonic LSD400HD-ST 4000 Lumens 1080p DLP Laser Business Projector

throw laser projector for compact rooms

The ViewSonic LSD400HD-ST is a Full HD DLP projector built around a laser phosphor light source rated for 30,000 hours. It produces 4,000 ANSI lumens and a 3,000,000:1 dynamic contrast ratio, so images stay bright and readable in meeting rooms, classrooms or golf simulators where ambient light cannot be fully controlled. A 0.496 throw ratio places a 100-inch picture just 1.1 metres from the lens. The sealed IP6X optical engine removes the need for lamp changes and cuts power draw by up to 49 percent.

Suitable for fixed installs needing flexibility.

IT teams and AV integrators who need 360-degree orientation, 90-degree portrait mode and horizontal or vertical keystone plus four-corner correction will find the mounting freedom useful. Built-in speakers handle basic audio without extra hardware. The unit weighs enough to require a solid ceiling or wall bracket, so users who move a projector between rooms daily should look elsewhere. Buyers who need 4K native resolution or motorised lens shift are also not served by this model.

0.496 throw ratio decides fit

At 0.496 the projector fills a 100-inch 16:9 screen from only 1.1 metres, letting it sit on a low shelf or short ceiling arm in shallow rooms. If the available mounting distance is longer than 3.29 metres or shorter than 0.44 metres the image size range of 40 to 300 inches cannot be reached. Confirm the exact throw distance in your space before ordering.
