Da-Lite 28844V 82" Parallax Pure Screen-ALR
Overview
Features HD Progressive surfaces designed for 1080p, 4K and Ultra HD! Ambient Light Rejecting Material!
Parallax Pure is an ambient light-rejecting technology that features a micro-layered optical lens system that rejects light. This new technology mimics the look of a television when it is on and when it is off, but without the glare from windows or lighting fixtures. With extremely wide viewing angles, no speckle and no glare, the surface is ideal for applications in Pro AV as well as Home Theater. Additionally, the surface is flexible, ships in a roll, and is easy to install. Each layer of Parallax Pure plays a role in preserving the image that is reflected back to the viewer in high ambient light environments. Some layers absorb light while one special layer is shaped like a microscopic saw-tooth that blocks light from above resulting in the preservation of high-contrast, bright images in brightly lit environments.
Ambient Light Rejecting (ALR) screens differ from a regular screens in several ways. The most common screen surfaces reflect the incoming light uniformly in all directions.
These screen surfaces are referred to as diffuse reflectors. The light is reflected back in many angles, rather than just at one angle. Surfaces that reflect back at only one angle are referred to specular reflectors - they reflect light at an angle precisely opposite the one at which that light arrived, such as a mirror.
Some projector screens may not be purely diffuse reflectors in the sense that they may reflect light back in one direction more than other directions. This is often done to increase the brightness of the reflected image (gain) within a certain area (viewing angle).
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.
Some ALR screens work due to a principal referred to as Angular Reflectivity. This means that your projected image will reflect back to the audience at the mirror-opposite angle to the projector hitting the screen. I.e. if the projector is angled down at a 15 degree angle, the audience will get the brightest image while viewing the screen looking up at 15 degrees.
Whichever the ALR technology that your surface is using, there will still be some ambient light that cannot be negated. ALR screens only work if the ambient lighting is NOT hitting the screen from the same direction the projector. I.E. if you have your projector positioned at the back of the room near other light sources that are also aiming towards your screen, the ALR surface will not do anything to negate that other lighting.
The ambient light source must be coming from a different direction/angle than your projector such as reflections off of white walls, overhead or recessed lighting or from windows on the side of your room in order to get the benefit of an ALR screen.
It will be fire retardant and mildew resistant, plus standard wall-mounting brackets will be included.

Installation is a breeze with the Da-Lite 28844V. The flexible screen ships in a roll and can be easily mounted to the wall using the included standard wall-mounting brackets. Plus, it is fire retardant and mildew resistant, ensuring long-lasting durability.
The Parallax Pure 2.3 surface is ideal for standard throw projectors with a 1.8:1 or greater throw ratio, while the Parallax Pure 0.8 surface is perfect for projectors with a 1.5:1 or greater throw ratio. For ultra short-throw projectors with a 0.4:1 or less throw ratio, the Parallax Pure UST 0.45 surface is the ideal choice.
In addition, the standard frame of the Da-Lite 28844V is equipped with Pro-Trim® finish, which absorbs the surrounding light to enhance the viewing experience. With a sleek design and high-quality construction, this screen is perfect for any setting.
Please note that in order to fully experience the benefits of the ambient light rejection technology, it is important to position the projector and screen in a way that the ambient light is coming from a different direction or angle than the projector. This means that the ALR surface will not be effective if the ambient lighting is hitting the screen from the same direction as the projector.
Upgrade your projection experience with the Da-Lite 28844V 82" Parallax Pure Screen-ALR and enjoy a superior viewing experience with vivid colors, sharp details, and no distracting glare.
