LED technology
Built with LED technology, this projector uses high-quality individual red, green and blue LEDs to create the projected image. In many situations, the perceived brightness from LED illumination can be twice that of an equivalent lamp-based model. This smart technology also delivers increased efficiency to maintain consistent brightness, superior colour across an extended lifespan.

Auto keystone
Auto keystone automatically adjusts the trapezoid effect to create a perfectly aligned image when a projector is off-axis, or the desired projection surface is not perfectly flat.
*Auto keystone only adjusts the image in the vertical plane.

Native office viewer
Give presentations directly from your projector without the need of a laptop or PC using the built-in office viewer. Simply copy your Word, Excel, PowerPoint, PDF or JPEG files to a USB stick, SD card or microSD (depending on the projector input*) and display them on the big screen.
