MX-ST3300U
SMX
A professional short-throw laser projector with 3300 lumens of brightness, native WUXGA 1920×1200 resolution and a 0.48:1 throw ratio. Designed for classrooms, meeting rooms, exhibitions, simulation spaces, and other installations where projection distance is limited.
3300 Lumens 0.48:1 Short Throw WUXGA 1920×1200 3LCD Laser 55–300" 20,000–30,000h
The MX-ST3300U delivers 3300 lumens of brightness for professional indoor projection environments. The laser light source provides stable image output while reducing the need for traditional lamp replacement.
It is well suited to classrooms, training rooms, conference rooms and controlled-light exhibition spaces.
The 0.48:1 short throw lens enables a large projected image from a relatively short lens-to-screen distance, making installation easier in rooms with limited depth.
Projection Distance = Image Width × 0.48
For example, a 4-meter-wide image requires an approximate projection distance of only 1.92 meters.

Native WUXGA resolution provides detailed images for presentations, graphics, simulation content and multimedia applications.
The native aspect ratio is 16:10, with compatibility for 4:3 and 16:9 content. The projector can also accept computer signals up to 4K@30Hz while maintaining a native WUXGA display resolution.
The projector uses three 0.64-inch LCD panels with MLA to create clear and consistent projected images.
3LCD technology is well suited to professional presentation, education and multimedia environments where stable color reproduction and readable image detail are important.
The projector is equipped with a RICOH projection lens featuring F1.6 aperture and 6.39 mm focal length.
Manual focus adjustment supports practical installation setup, while the 55–300 inch screen-size range provides flexibility for different room sizes and projection applications.
Flexible image adjustment tools help simplify installation when the projector cannot be positioned perfectly perpendicular to the screen.
Vertical Keystone: ±15°
Horizontal Keystone: ±15°

Barrel Correction
4-Corner Correction
6-Corner Geometry Correction
Grid Image Tune
The laser light source is rated for approximately 20,000 hours in Normal mode and up to 30,000 hours in ECO1 mode.
Long light-source life helps reduce routine lamp replacement and supports lower-maintenance professional installations.
The projector supports 360° projection orientation for flexible mounting in professional AV environments.
Connectivity and control options include HDMI, VGA, USB, RJ45, RS232, audio input/output and network control. Crestron RoomView, AMX Discovery and PJLink are supported for system integration.

The combination of 0.48:1 short throw optics, WUXGA resolution, 3LCD technology and flexible geometry correction makes the MX-ST3300U suitable for a variety of professional indoor applications.
Short projection distance helps reduce shadows and provides flexible installation in classrooms and training spaces.
WUXGA resolution, HDMI connectivity, and built-in 16W audio support professional presentations and everyday collaboration.
Short-throw installation and geometry correction make the projector suitable for compact exhibition and digital display environments.
The 0.48:1 throw ratio can help position the projector closer to the screen in simulation and training installations.
Short throw optics help reduce the distance between projector and display surface for interactive and specialized projection.
Geometry correction and 360° installation provide additional flexibility for compact creative projection environments.
Theoretical installation distance can be estimated using:
Projection Distance = Image Width × 0.48
Image Width | Approx. Lens-to-Screen Distance |
|---|---|
2.0 m | 0.96 m |
3.0 m | 1.44 m |
4.0 m | 1.92 m |
5.0 m | 2.40 m |
6.0 m | 2.88 m |
These values are theoretical optical references. Final installation should be checked according to actual projector position, screen size, mounting tolerance and site conditions.
