The HC7800D HD projector offers DLP, high-precision conversion and original 3D glasses with high-speed liquid-crystal shutter to deliver amazing performance. Using motion-vector analysis technology, 2D images converted to 3D have a natural sensation of depth. The optional glasses best match the high-speed DLP system. High-speed switching is over ten times faster than TN liquid-crystal shutter glasses, reducing blanking to 1/20 and resulting in amazingly low levels of eye fatigue.
