FAQ

1. What is a Black Grid ALR floor rising screen?

A Black Grid ALR floor rising screen is a motorized projection screen designed for ultra short throw projectors and laser TV systems. It uses a special ambient light rejecting surface to improve contrast and reduce the impact of surrounding light, while the floor rising structure allows the screen to retract neatly when not in use.

2. Is this screen suitable for ultra short throw projectors?

Yes. This screen is optimized for ultra short throw projectors and laser TV applications. The Black Grid optical surface is designed to work with the projection angle of UST projectors, helping deliver better contrast, clearer images, and improved viewing performance compared with ordinary white screens.

3. Can this screen be used with standard throw projectors?

This model is mainly designed for ultra short throw projectors. For standard throw or long throw projectors, we recommend using a Fresnel ALR screen, black crystal ALR screen, grey crystal ALR screen, or other screen materials designed for standard projection angles.

4. What does 0.6 gain mean?

A 0.6 gain surface reflects less light than a standard 1.0 gain white screen, but it helps improve black level, contrast, and image depth when used with ultra short throw laser projectors. This makes it especially suitable for home cinema environments where balanced brightness and deep contrast are important.

5. What is the viewing angle of this screen?

This Black Grid ALR screen offers a wide viewing angle of up to 170°, allowing viewers to enjoy a clear and comfortable image from different seating positions. It is suitable for living rooms, family rooms, home theaters, and entertainment spaces with multiple viewers.

6. Does the screen work well in bright rooms?

Yes. The Black Grid ALR surface is designed to reduce the influence of ambient light and improve perceived contrast in bright environments. For the best viewing experience, it is still recommended to avoid strong direct light hitting the screen surface.

7. What is the advantage of a motorized floor rising design?

The motorized floor rising design provides a clean and flexible installation solution. The screen rises smoothly from the floor case when in use and retracts back into the housing when not needed. It is ideal for rooms where wall-mounted or fixed frame screens are not preferred.

8. Is wall installation required?

No. One of the key advantages of this floor rising screen is that it does not require permanent wall installation. It can be placed in front of a wall, TV cabinet, or entertainment unit, making it suitable for modern living rooms, apartments, and multi-purpose spaces.

9. Is this screen suitable for laser TV?

Yes. This screen is suitable for laser TV systems and ultra short throw projectors. When paired with a UST laser projector, it helps create a large-screen viewing experience with improved contrast, richer colors, and better image visibility.

10. What is the difference between Black Grid ALR and Fresnel ALR?

Black Grid ALR screens are commonly used with ultra short throw projectors and offer a very wide viewing angle. Fresnel ALR screens usually provide higher gain and stronger directional light control, but the viewing angle is typically narrower. The best choice depends on the projector type, room environment, and viewing requirements.

11. Can the screen be hidden when not in use?

Yes. When the screen is not in use, it retracts into the floor case, helping maintain a clean and minimalist interior design. This makes it a practical choice for premium living rooms, home cinemas, meeting rooms, and entertainment areas.

12. How should I clean and maintain the screen surface?

Use a soft, dry microfiber cloth to gently remove dust from the screen surface. Do not use alcohol, strong detergents, abrasive materials, or excessive pressure. To protect the optical surface, avoid touching the screen directly with hands or sharp objects.

13. Is this screen suitable for home theater use?

Yes. With Black Grid ALR technology, 0.6 gain, 170° wide viewing angle, and a motorized floor rising structure, this screen is well suited for modern home theater, living room cinema, gaming, sports viewing, and premium entertainment applications.

14. Can the screen size be customized?

Standard sizes are available for common home cinema and laser TV applications. Custom sizes may also be available depending on project requirements, order quantity, and technical feasibility. Please contact us for more details about available sizes and customization options.
