Q: I have a short throw/ultra-short throw projector, will this projector work with the ambient light rejecting CineGrey 3D®/5D® materials?
The ambient light rejecting properties of the CineGrey 3D®/5D® make the materials incompatible with short throw and ultra-short throw projectors. The recommended minimum projector throw distance for these materials is 1.5 times the viewing image width. There are two main reasons behind this:
- The CineGrey 3D®/5D® are high gain and angular reflective screen materials. These types of materials require proper projector and screen alignment as hot-spotting may occur if not set up correctly.
- Due to the CineGrey 3D®/5D® materials being angular reflective, the angle of incidence from short-throw and ultra short-throw will be too close to the material and the viewer will not experience the optimal projector/screen performance. The material will treat the projector’s light as ambient light and thus it will reflect it in the wrong direction.
