Optoma EX550ST DLP Projector

Using the inherent speed of DLP™ technology, The Optoma EX550ST can output video and images at an astonishing rate of 120Hz, allowing you to show full screen, full color, 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 synchronize 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.

Six Segments Color Wheel increases the speed of the projector color wheel rotation from 2X (7200rpm) to 3X (10800rpm) resulting in consistent colors and seamless video playback. Also, the new 10 bit Color Processing technology increases the number of colors that can be display from 134.2 million to over 1073 million, presenting more natural & vibrant pictures.

Eco+ technology from Optoma increases our commitment to reduce the impact we all make on the environment. It reduces the power consumption to as little as 30%. This intelligent feature also has a positive effect on the lamp life, increasing it up to 70% while lowering the total cost of ownership and reducing maintenance.

Project an impressive 81" diagonal image from less than 1 meter away. Stand alone or wall mounted the EX550ST eliminates shadows on the screen and allows you to present with ease.

The function allows you to turn the power back on instantly. If the projector was turned off within 100 seconds by accident, this function allows the projector to boot up again instantly.
