24/7 operation
Optoma projectors have been designed to operate 24 hours a day in standard orientation. Perfect for applications where prolonged periods of use are required. Subject to 24-hour terms and conditions.
24/7 Operation - standard lamp warranty applies. The projector warranty is based on standard business usage hours. For optimum performance, Optoma recommends that your projector be turned off or placed in standby mode for 30 minutes every 24 hours to prolong the life of your lamp.
Auto power off
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+
Eco+ technology brings together high contrast, improved lamp life and energy-saving features that are easy to use while reducing power consumption.
Energy saving
Using the specially designed lamp modes, you can reduce power consumption by up to 70%. Each mode also has a positive effect on the lamp life, while reducing maintenance and helping to save on both energy and running costs.
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 power consumption by up to 70%, further prolonging the life of your lamp.
Quick resume
This feature allows the projector to be instantly powered on again if it is accidentally switched off.
Direct power on
The projector will start up instantly when power is supplied to the unit. This eliminates the need to manually turn on the projector via the remote control or the keypad, which is ideal for use in rooms with a “master” power switch.
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.
