Q:What are the primary applications for these screens?
A : Mocom’s front-projection screens are outstanding for public facilities, corporate training, gaming, and house of worship, and in home theater. A major application in development is dynamically-controlled advertising in public spaces.
Q:What are the Mocom concaved screens made of?
A : The Mocom concave screens are made from multiple layers of aluminum film, pressed using precision-ground lens molds against a fiberglass backing material to provide contour stability and strength. Larger screens (150″ and larger) employ a steel frame for rigidity and mounting, while smaller models use an attached fiberglass back bracket for mounting.
Q:What are the key differrences between Mocom's front-projection screens and conventional front-projection screens?
A :Mocom’s front-projection screens outperform conventional front-projection screens in every performance category. They provide higher gain, higher resolution, better contrast ratio, and better color accuracy than traditional screens. They also offer outstanding off-axis light rejection to allow them to be used in brightly lit spaces without the need for projector shroud or similar devices. Another benefit of the perfect lens shape is that images at the center of the screen reflect back to the viewing audience as if they were coming from the screen itself.
Traditional paper and glass-bead screens are only primarily more suitable than Mocom screens in where the screens need to be rolled up (Mocom 18-23gain front-projection screens are solid lenses, so they cannot be rolled up.
This performance benefits of Mocom screens will enable customers to place Mocom’s 18/23-gain screens into situations that previously would have required either rear-projection or video (e.g. plasma) displays. Mocom screens far outperform rear-projection or plasma displays. In addition, they provide far lower maintenance costs.
Q:How do you clean a Mocom screen?
A : Mocom concaved front projection screens have an ultra-fine grain which can pick up figerprint and dust. They can be cleaned using lint free cloth. In addition, you can use a hair dryer on COOL air to clean out the dust.
Q:Can I use Mocom concave screen (Solstice) in direct sunlight?
A : However, we do not recommend that you to use them it applications where the sunlight will be at the same angle as the projector light source for obvious reasons or in wet or windy condition. The off-axis ambient light rejection of these screens is astonishingly high, allowing them to be used as billboards under full vapor lighting in trade shows and other public facilities.
Q:What projector do I need?
A : It’s all depending on your needs. Bigger screen or brighter images will require higher lumens. We do not recommend short throw projectors because the curvature of the screen is calculated using a normal projector’s throw distance. For short throw projector’s, the curvature of the screen has to be calculated differently, so please check with us for more information if you need to use a short throw projector.
Q:What is the best viewing position?
A :In general the best viewing position is behind the projector. The optimal viewing position is equal to or further away from the screen than the center of the sphere represented by the screen’s curvature. For the larger Mocom screens, the center of the sphere is approximately 19.5 feet from the face of the screen. However, a large number of our screens in use are actively viewed at shorter distances and still achieve very satisfactory results. Please be aware that as you get close to the screen, limitations in the projector such as– pixelation, etc. — become visible due to the sharpness of Mocom screens.)
Q:How do I mount it?
A : Screens below 150″ come with a fiberglass back-bracket that has two vertical rows of threaded studs set approximately 6″ above the centerline of the screen. These can be mounted on hooks which will allow the screen to be swung into the correct angle for viewing.

Q:How to I adjust the screen angle for optimum light output?
A : It’s easy. Start by adjusting the vertical angle of the screen so that the center of the screen is exactly perpendicular to the line drawn from the light source (projector).
Then, adjust the vertical angle for the highest brightness when observed from the main viewing positions.
