Ideal for almost any room in educational and corporate environments, the EX665UT makes the most of the available space for installations using screens and interactive whiteboards.
Captivate your audiences’, increase their learning potential and help improve results with lessons in incredible 2D or 3D.
Using the specially designed wall mount* and clever cable management system the EX665UT is simple to install. Once in place the many security features ensure the projector is safe and secure.
Designed with the user in mind, the EX685UT with 3000 ANSI Lumens of brightness incorporates extensive connectivity, powerful 10W stereo speakers and Crestron RoomView® control to maintain and monitor the projector over the network. The environmentally friendly EX685UT has energy saving features including <0.5W standby mode and auto power off saving you both time and money. Our unique Optoma Colour guarantee ensure hassle-free, long-lasting projection.
Ultra Short Throw Lens
Position the EX685UT even closer to the wall so that the light beam doesn’t shine into your eyes. Project an impressive 60” diagonal image from just 46cm from the screen. Stand alone or wall mounted the EX685UT eliminates shadows on the screen and allows you to present with ease.
Perfect for Teaching
Maximise space in the classroom for teachers and students. The teacher can stand close to the interactive whiteboard without having the intense light from the projector shining directly into their eyes.
Grab your audience’ attention with bright, vivid projected images thanks to the BrilliantColor™ technology incorporated within the EX685UT. Preset display modes allow you to achieve a perfect image on a variety of surfaces including screens and interactive whiteboards.
Kensington Lock, security bar and password protection help secure your projector and act as a theft deterrent.
Customised start-up screen helps identify who the projector belongs to.
Keypad lock prevents unauthorised adjustments and ensures the projector can only be controlled via the remote control or network.
Brilliant Colours That Last
Project stunning, vibrant and accurate colour images that won’t decay overtime thanks to BrilliantColor™ and DLP® technology.
Easy to Control and Monitor
Crestron RoomView® software provides a custom configurable interface to monitor, manage and control every projector in every room remotely from any computer.
Energy Efficient = Environmentally Friendly = Save Money
Running costs are reduced thanks to reduced power consumption and standby mode <0.5W. When the projector is no longer required it will automatically turn off, saving energy and prolonging the life of the lamp.
Future proof technology for the classroom
Engage and inspire your students with 3D lessons in Biology, Maths, Geography and many more.
Caring for the Environment
The EX685UT incorporates energy saving features to conserve power and extend the lamp life:
To achieve the maximum 3000hrs lamp life time the projector should be operating in ECO mode and the shut down timer enabled to automatically switch off the projector if it is accidentally left on when no longer required.
Optoma’s low energy standby mode significantly reduces power consumption, enabling environmentally friendly power management and lower cost of ownership.It takes less than 10 seconds for the projector to power up and shutdown, saving both time and energy.
We know that improving our products is the best way to reduce our impact on the environment. That’s why at Optoma, we design our products to have a long usable life, use fewer materials, ship with the minimum packaging and be free of all possible toxic substances.

How does 3D work?
Using the inherent speed of DLP® technology, Optoma 3D-Ready projectors can output video and images at an astonishing rate of 120Hz, allowing you to show full screen, full colour, stereoscopic 3D.The 3D effect is generated by splitting this signal into two standard video streams, one for each eye. Using DLP® Link™ technology, the 3D glasses synchronise with the image on screen to filter each stream to the correct eye. Your brain then combines the two streams to make them jump into life.
