Elite Screens’ CineGrey 3D®/5D® is a color neutral smooth surface with sparkling elements to increase screen gain in an ambient light room environment. These special characteristics incorporates a diffusion layer over a highly reflective surface which scatters ambient light while improving picture performance with a brighter image. The projector itself, however also plays a big part in creating a hot spot. Projectors highest brightness levels are focused in the center, and only about 70% to 80% in the corners. In other words, the uniformity itself is not spread entirely even across the screen, thus creating a brighter spot in the center area. To combat this, we recommend the following.
- Reduce the projector’s light output by choosing an economy mode
- Install the projector further away from the screen, minimum of 1.5 x the image width
- Go with a lower gain screen
