Active 3D– All of Elite Screens’ materials are compatible with active 3D projectors.  The system utilized by Active 3D projector setups does result in an overall loss in brightness however. When 3D mode is activated on a projector, up to 50% of the lumen output is lost. The image brightness is further diminished as the viewer is required to use dark tint glasses.  If the majority of viewing will be done in Active 3D, Elite Screens recommends a higher gain screen materials such as, CineGrey 3D® and CineGrey 5D®, to help offset lumen loss.

1. 3D Polarized Silver Screen: Elite Screens Airbright3D2 on either a fixed frame or tensioned electric “roll-up” configuration.
2. Two Projectors (DLP or LCD or Lcos), any brand ok. *Pref. matching models that have the same resolution, aspect ratio, and throw distance for the best results.

Ultra/Short-throw projectors require a flat projection surface since the projector’s light is closer to the material.  Non-tensioned screen materials may exhibit minor wave or curls which may be more pronounced if using an ultra/short-throw projector.   We recommend using a Fixed Frame Screen or a Tab-Tension screen with PVC such as our CineWhite® flexible material which will provide adequate tension throughout the entire projection surface. Please click here to learn more about the CineWhite® screen material. Our Aeon CLR®, EDGE FREE® Fixed Frame is recommended for table-top ultra-short throw projectors in an ambient light room environment. Please click here to learn more about the Aeon CLR®.

A Hot Spot occurs when a projection screen cannot evenly diffuse a strong light signal creating a noticeably brighter area in the picture. With rear-projection screens, it will appear to viewers as a bright spot marking the location of the projector’s lens behind the screen. This is a common occurrence in rear projection screens; essentially a hot spot is when you can see the projector bulb through the screen’s surface. The following should be considered to reduce the possibility of having a hot spot.

1. Reduce the output power of the projector. Choose a lower lumens (brightness) setting like Cinema for example.
2. Avoid using ultra/short-throw projectors since the bulb will be very close to the material.
3. Move the projector further away from the screen.  This will increase the throw distance of the projector, and will effectively reduce the intensity of the image brightness.
4. Reposition the projector relative to the audience.  Raising the projector’s height or lowering it so it is not projecting directly into the viewer’s line of sight.  Use vertical lens shift to achieve vertical off-axis projection and use the keystone adjuster to restore the image’s rectangular shape.
5. Another idea is to position the projector horizontally off-axis so that the projector’s glare will not be in the viewer’s line of sight.

Black Backing is an important feature that prevents light penetration and increases reflectivity for sharper color reproduction.

Screen material selection will depend on various factors such as type of application, environment, and projector.  Please see the screen material selection guide for a better understanding of the materials we offer. Screen Material Selection Guide 

The percent of gain difference between 1.0 and 1.1 is 10%. A gain of 10% brightness is gained from the projector’s lumens output.   Example : If a projector has 1000 lumens you’d gain 10% if the material gain is 1.1. 1000 x 1.1 = 1100

The reflective properties of the Wraith Veil rear projection material may cause a hot spot.  This is normal for this material and thus, the following should be considered to reduce the possibility of having a hot spot.

1. Reduce the output power of the projector. Choose a lower lumens (brightness) setting like Cinema for example.
2. Avoid using ultra/short-throw projectors since the bulb will be very close to the material.
3. Move the projector further away from the screen.  This will increase the throw distance of the projector, and will effectively reduce the intensity of the image brightness.
4. Reposition the projector relative to the audience.  Raising the projector’s height or lowering it so it is not projecting directly into the viewer’s line of sight.  Use vertical lens shift to achieve vertical off-axis projection and use the keystone adjuster to restore the image’s rectangular shape.
5. Another idea is to position the projector horizontally off-axis so that the projector’s glare will not be in the viewer’s line of sight.
