Direct power off

Power off your projector immediately or directly at the mains. This means you don’t have to wait for the projector to cool down before turning it off.

Quick resume

This feature allows the projector to be instantly powered on again, if it is accidentally switched off.

Energy saving

Using the specially designed lamp modes, you can reduce the power consumption by up to 70%. Each mode also has a positive effect on the lamp life, while lowering the total cost of ownership and reducing maintenance.

There may be instances when the projector is left running when not in use. To help save energy, the "auto power off" feature automatically turns off the projector after a set period of time if it is not being used

Eco AV mute

Stay in control of your presentation with Eco AV mute. Direct your audience's attention away from the screen by blanking the image when no longer needed. This also reduces the power consumption by up to 70%, further prolonging the life of your lamp.
