-
2nd generation Laser Phosphor technology
Thanks to 2nd generation Laser Phosphor technology, it improves brightness (by 20%), heat resistance and reduces the product size in addition to excellent color performance, lamp-free design and instant on/off switch.
-
Reliable long-term performance
Laser technology offers a lifespan of up to 20,000 hours (four 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.
