It delivers Full HD 1080p resolution with laser light source, ensuring vibrant and detailed imagery even in well‑lit rooms, and it operates almost maintenance‑free for thousands of hours thanks to advanced laser technology.

Product Features (In Full Detail)
Bright Full HD Laser Projection
First, this projector produces 4200 ANSI lumens of brightness, which ensures clear and bright images in various lighting conditions without needing a dark room. The Full HD 1080p resolution means images and text look sharp and detailed, so presentations, videos, and graphics stand out with clarity.
Short Throw Lens
Furthermore, the short throw lens allows you to project a 100‑inch image from just a few feet away, reducing shadows and minimizing space constraints, which is ideal for smaller rooms or tight installation spots.
DuraCore Laser Technology
Also, the projector uses DuraCore laser technology, giving up to 30,000 hours of virtually maintenance‑free operation. This not only extends lifetime but also lowers total cost of ownership by reducing downtime and service needs.
Advanced Control Options
In addition, the ZH406STx offers ultimate control compatibility with systems like Crestron, Extron, AMX, PJ‑Link, and Telnet, allowing centralized management and ease of integration into complex AV networks.
IP6X Dust‑Resistant Engine
Moreover, its IP6X rated airtight optical engine provides outstanding dust resistance, which helps maintain performance and brightness over time, making it suitable for 24/7 operation in harsher environments.
Flexible Installation
Additionally, the projector supports auto and four‑corner keystone correction, portrait mode, and 360° projection — giving you more installation freedom and image alignment control in non‑traditional setups.
Integrated Sound & Connectivity
Finally, built‑in speakers offer decent audio without requiring extra equipment, and the USB‑A port can power dongles like Chromecast for wireless streaming and simplified connectivity.
Why Choose the Optoma ZH406STx?
