1. What is a UST ALR screen?
A UST ALR screen, or Ultra Short Throw Ambient Light Rejecting screen, is a specialized projection screen designed to work specifically with ultra short throw projectors. The screen is designed to minimize the negative effects of ambient light, producing high-quality images even in well-lit environments.
2. What are the advantages of using a UST ALR screen?
1. High Contrast: UST ALR screens are designed to reject ambient light and increase the contrast of the projected image. This results in a clearer and more vivid image, even in brightly lit rooms.

2. Wide Viewing Angle: UST ALR screens have a wide viewing angle, which means that everyone in the room can enjoy a clear view of the projected image, no matter where they are seated.

3. Easy Installation: UST ALR screens are designed to be installed very close to the wall, which makes them ideal for small spaces or rooms with limited space. They are also relatively easy to install and can be done without the need for professional assistance.

4. Minimal Screen Glare: UST ALR screens have a special surface that reduces glare and reflections from ambient light sources. This helps to ensure that the projected image is clear and easy to see, even in bright rooms.

5. Compatibility with Ultra-Short Throw Projectors: UST ALR screens are designed to work seamlessly with ultra-short throw projectors. This combination produces an immersive, cinema-like experience, which is ideal for watching movies or playing video games.

3. What kind of screen do you use for a UST projector?

It is recommended to use a specially designed UST projection screen. UST screens are designed to reflect the light from the projector at a wider angle, reducing the risk of hotspots and providing a better viewing experience. They are also made with materials that help to reduce ambient light and enhance the contrast and clarity of the projected image. WEMAX provides 100-inch and 120-inch ALR ambient light rejecting screen for UST projectors.
4. What is the difference between ALR and CLR screen?
The main difference between ALR and CLR projector screens lies in how they reject ambient light. ALR projector screens reflect ambient light away from the audience, while CLR projector screens absorb ambient light. CLR projector screens also specialize in rejecting overhead light.
5. How does a UST ALR screen work?
ALR screens work on the principle of either not reflecting ambient light like in a black screen or by having a special microscopic saw tooth shaped surface which allows for selected Angular Reflectivity.
6. How do I choose the right size for a UST ALR screen?
When choosing the right size for a UST ALR (Ultra-Short Throw Ambient Light Rejecting) screen, you should consider the size of your room and the distance between your projector and the screen. Measure the distance between the projector's lens and where the screen will be placed, and choose a screen size that is appropriate for that distance.
