ViewSonic LS921WU WUXGA Short Throw Laser Projector – 6000 ANSI Lumens, Lens Shift, HDBaseT, HDR

The ViewSonic LS921WU is a 6,000-lumen WUXGA short throw laser projector for large rooms with limited depth. It suits golf simulators, museum exhibits, classrooms, and stage installs, pairing a 0.81–0.89:1 lens and full lens shift with HDBaseT and a 20,000-hour laser.

Deep-Dive Story & Problem/Solution

Bright Large-Format Projection in Rooms Without Throw Distance

Simulation bays, exhibition spaces, and rear-of-stage positions rarely offer the 15 to 20 feet a standard installation projector needs. Short throw models solve the distance problem but have typically been limited to around 4,000 lumens and fixed lenses.

The LS921WU brings 6,000 ANSI lumens to a 0.81–0.89:1 short throw lens with 1.1x zoom. A 100-inch 16:10 image needs only about 5.8 to 6.3 feet, and horizontal and vertical lens shift let installers offset the projector from screen center.

A laser phosphor source rated for 20,000 hours, HDR10 and HLG compatibility, and dual HDMI 2.0 inputs make it suitable for video-rich applications that run all day.

6,000 Lumens From a Short Distance

Images from 60 to 200 inches stay bright and sharp at WUXGA resolution. Keystone correction of up to ±40 degrees in both axes handles difficult angles.

Integration-Ready Connectivity

HDBaseT, VGA in/out, composite, S-Video, USB, and RS-232 are on board. Noise falls to 29dB in low-brightness mode and built-in dual speakers supply local sound.

Setup Instructions

How to Install the ViewSonic LS921WU

1. Mount the projector about 5.8 to 6.3 feet from a 100-inch screen, scaling distance for larger sizes.
2. Connect HDMI or HDBaseT sources and control cabling.
3. Use lens shift, zoom, and focus to position and sharpen the image.
4. Adjust keystone if needed and choose the brightness mode for the venue.
