Featuring XGA (1024 × 768) resolution and 4000 ANSI lumens brightness, it delivers sharp and vibrant visuals suitable for presentations, videos, slideshows, and teaching content — even with ambient light present.

Built with LCD display technology, the ALX402 produces well‑defined imagery and reliable color performance that enhances clarity during lectures, business meetings, or multimedia sessions. It boasts a high contrast ratio (20,000:1) for deeper blacks and better visual depth, improving readability and detail.

The projector supports a standard throw lens with a throw ratio of approximately 1.48–1.78:1, enabling flexible placement and projection sizes ranging roughly from 30″ up to 300″ diagonal. Manual optical zoom (1.2×) and vertical ±30° keystone correction make image alignment easier in varied room layouts.

Connectivity options include common interfaces like HDMI, VGA, USB‑B, and RJ45, while the USB port can also read and display content directly, with optional wireless projection support via an adapter. A built‑in 10 W speaker provides basic audio without needing external speakers.

The ALX402’s long lamp life (up to 20,000 hours in eco mode) reduces maintenance costs, and its compact, lightweight design (~3.06 kg) makes installation and repositioning simple.

Overall, it’s a practical and durable projector that delivers bright images, flexible setup, and dependable performance for classrooms, boardrooms, offices, and similar environments.
