ViewSonic LS921WU Laser Installation Projector
6000 Lumens, 16:10 WUXGA

OVERVIEW
The LS921WU is an advanced 6,000 ANSI Lumens WUXGA short throw installation projector. Adopting 2nd generation Laser Phosphor technology, the LS921WU offers high and consistent brightness with a lifespan of 20,000 hours and a screen size of up to 200”. Short throw ratio, 1.1x optical zoom, wide lens shift, 360° projection, and portrait mode combine for incredible flexibility to create a truly immersive experience, especially ideal for blending projection applications in restaurants, gyms, and simulation/experience centres. Dual HDMI 2.0b / HDCP 2.2 ports ensure access to original 4K quality content with HDR/HLG formats supported. Add to that the compact size and built-in HDBaseT for the perfect mix of high-quality projection and cost-effectiveness.

2nd Generation Laser Phosphor Technology

Brighter, Smaller, Safer
Reliable Long-Term Performance
Laser technology offers a lifespan of up to 20,000 hours (4 hours per day for more than 13 years) with no degradation in brightness over time so that your installations are consistently vibrant.

No Shadows, No Blinding Lights
With the latest projection technologies from ViewSonic, you'll enjoy all the benefits a short throw projector can offer. When projecting on to a video wall, there are no distracting shadows on the screen image, offering excellent edge blending projection. Plus, a 1.1x optical zoom provides a higher level of flexibility to fit some of the most challenging installation environments.

1.1x Optical Zoom
Larger Screen Size, Lower Cost-Per-Inch
Flexible installation and effortless transportation of the projector allows for an up-to-200” image size, which is much larger and easier to install than multiple commercial displays combined.
Installation Flexibility
The tool-free, lens shift control knobs make adjusting the projection lens up, down, left, and right easy. It provides flexible installation options with a wide adjustable range (H: +/- 23%, V: +/-50%) and less placement restrictions.
Wide H/V Lens Shift
360° Creative Applications
The projector can freely rotate at any angle vertically to aid with creative applications, allowing projection onto ceilings, walls, or angled signage.
90° Portrait Mode
Portrait mode allows users to turn the projector 90 degrees to increase the vertical field of view and add more applications for projection mapping, staging, and advertising.
Dual HDMI 2.0b Supporting 4K/HDR/HLG
It comes with dual HDMI 2.0b / HDCP 2.2 ports, ensuring your access to original 4K quality content with HDR/HLG supported at a 60Hz frame rate from external devices (e.g. Roku stick, 4K Blu-ray player), producing the brightest whites, deepest blacks, and showing more picture detail.
4K/HDR/HLG Support
Lighter Weight & Compact Size
It is almost half the weight and 35% smaller in size when compared with its predecessor, which reduces the cost of transportation and enhances the ease of installation.

With a built-in HDBT receiver, this projector can receive uncompressed high-resolution video and audio over long distances (100 m for 1080p) via a Cat.5e/6 single network cable and is compatible with any certified HDBaseT transmitter.
