ViewSonic LS901-4K
Score: 89/100Rankings
The ViewSonic LS901-4K is a professional-grade laser projector delivering 5,500 lumens and a 3,000,000:1 contrast ratio for large-venue installations. Its laser source and extensive adjustment options add flexibility but bring higher power consumption and cost. Best for corporate, education or home-theater users needing bright, high-contrast images and advanced installation features.
The Optoma HZ40HDR is a compact laser projector delivering 4,000 lumens and ultra-low 8.6 ms input lag, making it ideal for bright-room gaming and home theater. Its native 1080p panel limits true 4K detail and the built-in 15 W speaker is modest. Best suited for gamers and users needing portability.

Professional reviewers commend the HZ40HDR for its impressive 4,000-lumens laser brightness, ultra-low 8.6 ms input lag, high contrast, and eco-friendly DuraCore laser, positioning it as a top choice for bright-room gaming and home entertainment, while noting the limitation of a native 1080p panel and modest built-in audio.
Everyday users praise the projector's easy setup, bright performance in lit environments, and responsive gaming experience, but many express disappointment about the lack of true 4K resolution, weak internal speaker, and occasional fan noise.
