Superior contrast
Add more depth to your image with a high contrast projector. Compared to competing technology, Optoma DLP projectors provide you with brighter whites and ultra-rich blacks, images come alive and text appears crisp and clear - ideal for business and education applications.
Full 3D
Optoma projectors can display true 3D content from almost any 3D source, including 3D Blu-ray players, 3D broadcasting and the latest generation games consoles.
Integrated speaker
A powerful built-in speaker provides exceptional sound quality and an easy setup without the need for costly external speakers.
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 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.
Quick resume
This feature allows the projector to be instantly powered on again, if it is accidentally switched off.
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.
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, 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.
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
