The Optoma W303ST is portable and robust, allowing the projector to be mounted on the ceiling in a classroom or placed on a table in a meeting for the ultimate in installation convenience.

Full 3D

Display true 3D content from almost any 3D source, including 3D Blu-ray Disc™ players, 3D broadcasting, and the latest-generation game consoles. Support for 144Hz rapid-refresh rate provides ultra-smooth flicker-free images. DLP Link 3D glasses required.

High Contrast

Add more depth to your image with a high-contrast projector. With brighter whites and ultra-rich blacks, images come alive and text is crisp and clear.


Specially designed lamp modes reduce power consumption by up to 70%. Each mode also improves lamp life, which lowers the total cost of ownership and reduces maintenance.

Auto Power Off

To help save energy, this feature automatically turns off the projector after a set period of time, if it is not being used.
