Large Images in Small Spaces

A short throw lens enables large images to be projected from short distances in small rooms. In addition, any blinding lights in front of the presenter, distracting shadows on the projected image, or glaring hotspots on the screen, are all eliminated because the projector’s light source is closer to the projection surface.

Network Monitoring & Control

IT admin can monitor, schedule, and manage the projector remotely, as well as receive projector status alerts, with the integrated Crestron® e-Control™ system and RoomView Express management software. Because this projector is Crestron® and AMX® certified, IT admin can control and monitor the projector for any size campus or enterprise.

Optional Ambient Light Screen

To further reduce any effects of high ambient light, and to take full advantage of the incredible images projected, we recommend pairing our laser projectors with our optional black diffuser screen. This black screen enhances contrast and helps to eliminate washed out images in ambient light.

360-degree Orientation

A robust mechanical construction allows the projector to be installed in nearly any position, at any angle from floor to ceiling. You can mount the projector pointing straight down at the floor, or mount the projector upside-down at a 45-degree angle if need be.

SonicExpert® Technology

This projector is designed with ViewSonic’s proprietary SonicExpert technology that incorporates an enlarged speaker chamber and a more powerful amplifier to deliver a full 20Hz – 20Khz sound range. Dual integrated speakers captivate your audience with immersive sound.
