The Qumi by Vivitek isn't just one of the smallest projectors in the world. It could also be the very first beamer of its size to display 3D content. Measuring about 6.4 inches by 1.3 inches by 4 inches (about the size of a 300-page paperback), this pocket projector doesn't quite fit in your jeans pocket, but it is still incredibly small.
Some key specifications of this LED projector include a 1,280x720 native resolution, 300-lumen brightness, and DLP Link 3D synchronization technology. DLP Link inserts information between video frames for synchronization with active-shutter 3D glasses. This means you won't need an infrared or Bluetooth connection with the projector, unlike most 3D TVs today.
Unfortunately, we couldn't find any information about the 3D formats supported by the device. Current 3D TVs work with frame packing, top-and-bottom, and side-by-side content.
The Qumi still appears to be one capable and lightweight projector--it weighs 1.4 pounds--and doesn't cost a bomb at $499. It's available now at Amazon.
