Product Description
What’s ALR screen? How does it work? Why is it so popular recently?
To help clear these confusion, here are some things to know:
1. The term “ambient light rejecting” or ALR, is a nomenclature in AV industry referred to a particular screen feature that prevents ambient light from washing out a projected image. In English, pictures projected on ALR screen will have solid color saturation and sparkling high contrast even in a well-lit room.
2.Ambient light includes - but is not limited to - light coming through windows, in wall/ceiling lights, lamps, candles, fireplaces, or even the light of your own video screen reflecting off light-colored surfaces in your room, and they will all impair the quality of your projected image.
3.ALR screens come in two basic types: "retro reflective" or "angular reflective." The difference lie in the direction they reflect the image. And retro reflective ALR is the preferred format in high performance home theater applications.
4.There is no ALR screen that can reject 100% of ambient light.
5. To get the most out of your ALR screen, make sure you follow its installation instructions. Projector placement plays an important role in enhancing the ALR effect.

SCREEN MATERIAL
8K Black Crystal ALR screen material is an angular reflective front projection material designed to reject ambient light while maintaining superb picture quality. It is the perfect solution for rooms that have little or no control over incidental light. The 8K/4K Black Crystal ALR is superior to traditional white or gray materials in its ability to maintain a sharp, bright image regardless of ambient light.

Projector Info
*Not compatible with ultra short throw projectors or edge-blending due to risk of hot spots
*Works best when the minimum throw distance is 1.5 times the width of the image
*The ambient light must never come from the same direction as your projector
*Install the projector so the projected light mirrors the reflected light with equal angles and is aligned at eye level for best results.
HOW DOES IT WORK?
An ALR screen works by selectively reflecting light back to the audience. This effect is achieved by positioning the projector and screen in such a way that the projector's light is bounced towards the audience, while the other light in the room is reflected back in some other direction.

HOW TO CHOOSE SCREEN SIZE CORRECTLY
There are mainly four factors you need to consider before choosing the best screen size:
1. Projection Wall Dimensions
2. Projection Distance
3. Projector Brightness(Lumens)
4. Viewing Distance
There are mainly four factors you need to consider before choosing the best screen size:
1. Projection Wall Dimensions
2. Projection Distance
3. Projector Brightness(Lumens)
4. Viewing Distance
Projector Brightness / Screen size*2 = Unit Brightness Index
eg: XGIMI H1S ( 1100 ansi) 100inches
1100/100/100=0.11
***the higher the unit brightness index, the stronger the anti-light ability, the better the picture quality
MORE DETAILS
Sharp colors and improved contrast, regardless of excess light
Our 8K Black Crystal/diamond ambient light rejection delivers near-perfect color accuracy in both high and low light conditions.The ambient light reflective coating of our black diamond screen contains millions of nanoparticles that reflect light back towards its source.
Multiple Layers of Light Rejection Technology all in One Screen
We’ve engineered our signature ALR material with multiple layers, offering you the best optical light rejection capabilities in the market. From the reinforced backing that blocks light from going out of the screen; to high reflectivity screen substrate,reflective nanoparticle treatment and smooth optic layer, all of your screen’s components ensure excess light is reflected while your content is enhanced and brightened.
The Perfect Picture – Regardless of the Environment
Our specially engineered ambient light rejection technology was developed to reject every bit of any off axis source of light,making your content appear crisp and sharp, even in brightly lit rooms. Ensuring excess light doesn’t disturb your viewing while still delivering your content with sharper colors and better contrasts.
Nanotechnology Engineered to Enhance Your Content
Scattered light is the reason your projections might not be looking as neat as you need them to. That’s why we’ve designed a screen material that incorporates reflective nanoparticles. These tiny particles reflect excess light, guaranteeing the only light you see is the one coming from your projector.
DIMENSIONS
What is the Right Aspect Ratio / Format for you?
--- 1:1 Square Format:This aspect ratio provides a perfectly squared screen format for overhead projectors (OHP) and is commonly used in Educational/Classroom environments.
Tip: Choose this format if you are using a native SVGA/XGA Projector and occasionally use an OHP or 1:1 slide projector for your presentations.
--- 4:3 Video Format:This aspect ratio is the same as a standard television (Non-High Definition) or computer (SVGA, XGA, UXGA)resolution.
Tip:Select this format screen if you are using a native SVGA, XGA or UXGA projector for your presentations.
--- 16:9 HDTV Format:This is the High Definition Television (HDTV) format and is the most widely used aspect ratio for the latest television designs.
Tip: Choose a 16:9 Projection Screen if you are planning to use it with a native 16:9 format projector.
--- 16:10 PV Widescreen:This is the most popular aspect ratio for the latest WXGA or WUXGA notebooks.
Tip: Choose the 16:10 screen if you use a native wide screen notebook or wide XGA (UXGA) projector.
--- 2.35:1 Widescreen Cinemascope format:This is perfect with the new anamorphic lenses on the market today.
Tip: Select this 2.35:1 format screen if your application is strictly home theater Cinemascope presentations. 2.35:1 and 16:9 are the most popular format for Home Cinema.
Screen Material Maintenance Care
Dust, dirt and scratches on the projection screen surface will affect the quality and performance of the projection image.Followthe instructions below to properly maintain the screen.
1. Materials needed: 2 Microfiber cloths and water.
2. Gently blot the area using a lightly dampened lint-free microfiber cloth with clear warm water. DO NOT rub.
3. Using the damp cloth, lightly wipe in an up and down motion starting at the left of the screen moving to the right of the screen. DO NOT WIPE IN CIRCULAR MOTION.
4. To clean a stubborn stain or a sticky surface, spray a solution of equal parts Formula 409 and warm water onto a lint-free microfiber cloth. DO NOT SPRAY THE SCREEN MATERIAL DIRECTLY.
NEVER ALLOW ANY SOLVENTS TO DRY ON THE MATERIALS AS THEY WILL CREATE A STAIN THAT IS NONREMOVABLE.
**If Heavily soiled (marked permanently): Unfortunately you may NOT use any solution to clean the surface as it will damage the screen. If there is a mark, it is permanent.
• You can NOT repair a screen if it is torn.
