Direct Power On

Turn on the projector directly from the power source. This feature aids installations that rely on power-on timers. The sleep timer can be used to turn the projector off after a set time.


Specially designed lamp modes reduce power consumption by up to 70%. Each mode also improves lamp life, which lowers the total cost of ownership and reduces maintenance.

AV Mute

When enabled via remote control or network management, the projector suspends (dims) video output to conserve energy.

Auto Power Off

To help save energy, this feature automatically turns off the projector after a set period of time, if it is not being used.

Short Throw Projection

Project images in limited space environments with short-throw projection. The short-throw lens requires short distances to project large images.
