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.

Quick Resume

This feature allows the projector to be instantly powered on again within 100 seconds of turning it off.

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.

Full HD 1080p

1080p (1920×1080) resolution renders sharp and detailed images from HD content without downscaling or compression, which is perfect for movies, TV shows and gaming.

Ultra Short Throw

Ultra short throw projection enables closer placement to the wall with reduced shadows for easy presenting. The placement makes it perfect for interactive applications and education environments, too.
