Main Features:

  • Short Throw Projection: With a short 0.62:1 throw lens, you can project an impressive 100” image from just over a meter away. This allows you to place the projector closer to the wall, reducing shadows so you can present with ease.
  • Amazing colors: Give powerful presentations and educational lessons with stunning colors. Optoma projectors provide reliable color performance suitable for any content and environment. From accurate sRGB colors for lifelike images to vibrant punchy presentations, there is a display mode to specifically meet your needs. Perfect for a range of graphic and video presentations.
  • Superior contrast: Add more depth to your image with a high contrast projector. Compared to competing technology, Optoma DLP projectors provide 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. 3D content can be viewed with DLP Link active shutter 3D glasses when projector is used with a compatible 3D player. (DLP link 3D glasses sold separately.)
  • Integrated speaker: A powerful 10 W built-in speaker provides exceptional sound quality and an easy setup without the need for costly external speakers.
  • HDMI Link: Lets you turn on and off two or more HDMI-CEC capable devices using a single remote control.
  • MHL Connectivity: Turn your projector into a smart display by connecting your smartphone or tablet with a single cable using MHL. Now you can view presentations and documents, stream videos and share photos on the big screen.
  • 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 is required.* 

* Standard lamp warranty applies. Projector warranty is based on standard business usage hours. For optimum performance Optoma recommends to turn off your projector, or place it in standby mode, for 30 minutes every 24 hours to prolong the life of your lamp.


Eco+ Features

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: 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.
