This mini-projector is equipped with the active shutter 3D-imaging technique used by DLP cinema projectors. The 3D movie source that i've tested so far, is just coming from video streaming on this projector, and the result is GREAT! This mini-projector almost have it all. It has an ethernet port, wifi, bluetooth, auto keystone correction, usb2 and usb3 port, mira-cast, Hdmi/MHL, and full Android functions. SPDIF audio out not tested yet, but there is a Raw feature in audio settings for digital out. The audio output from the internal speaker of this pj is also good, but not great, but remember you can connect your bluetooth speaker anytime. Really bright projector, with fair contrast, good image color in general but it has an intense red color but you can adjust it in user's color settings. Since this is an Android projector it can handle my air mouse remote for convenient operation.
