The CineGrey 3D® (AT)/CineGrey 4D (AT)/CineGrey 5D® are angular reflective front projection materials that reflect at the mirror-opposite angle. If an ultra-short throw projector is used, the material will reflect the steep narrow light and reflect it upwards instead of to the viewer’s eye level.

The image appears to look good, but is still reflecting the projector light upwards and causing a hotspot in the middle of the image. Overhead lights are being absorbed/reflected off the material while providing great color saturation, image brightness, and black levels for a contrast rich presentation. Model# AR100DHD3 – CineGrey 3D® EDGE FREE 100” Diagonal 16:9 Fixed Frame with JVC LX-NZ3B 4K HDR Laser Projector

Q: Will the CineGrey 3D (AT)/4D (AT)/5D® ambient light rejecting screen material cause the “hot spot” effect?
Q: Will the CineGrey 3D (AT)/4D (AT)/5D® ambient light rejecting screen material cause the “hot spot” effect?

Elite Screens’ CineGrey 3D® (AT)/4D (AT)/5D® is a color neutral smooth surface with sparkling elements to increase screen gain in an ambient light room environment. These special characteristics incorporates a diffusion layer over a highly reflective surface which scatters ambient light while improving picture performance with a brighter image. The projector itself, however also plays a big part in creating a hot spot. Projectors highest brightness levels are focused in the center, and only about 70% to 80% in the corners. In other words, the uniformity itself is not spread entirely even across the screen, thus creating a brighter spot in the center area. To combat this, we recommend the following.

1. Reduce the projector’s light output by choosing an economy mode
2. Install the projector further away from the screen, minimum of 1.5 x the image width
3. Go with a lower gain screen

Q: I have a short throw/ultra-short throw projector, will this projector work with the ambient light rejecting CineGrey 3D® (AT)/CineGrey 4D (AT)/5D® angular-reflective materials?

No, ultra-short and short-throw projectors are not compatible with CineGrey 3D® (AT)/CineGrey 4D (AT)/5D® angular-reflective materials.

“Yes they can be used with Active 3D projectors.”

Q: How well does the CineGrey 5D®/CineGrey 3D® (AT)/CineGrey 4D (AT) perform in a dark room environment?
Q: How well does the CineGrey 5D®/CineGrey 3D® (AT)/CineGrey 4D (AT) perform in a dark room environment?

The CineGrey 5D®/CineGrey 3D® (AT)/CineGrey 4D (AT) are great for dark room environment also, but we must understand its limitations. First of all, both materials have narrow viewing angles. So if you wish to have a wide seating arrangement after 80 degrees, you will notice a drop in brightness. Second, because they are higher gain screens they reflect more projector brightness. This may tire your eyes, so we recommend using a less brighter mode if your projector has a such setting. If that is not a problem, then these materials will work. And the best thing is, because they are angular reflective material, the projector’s light will not diffuse in all directions like a matte white material. Meaning that they will not scatter the projector’s light and create side lighting. Thus, eliminating the need to absorb it with black velvet or paint a room really dark. Third, because both of these materials are made with a neutral gray substrate, the color balance and temperature will be exceptional. The dark gray also enhances contrast and great color saturation.

Q: What are the benefits of using CineGrey 3D® (AT)/CineGrey 4D (AT) or CineGrey 5D® material in a dark room with white ceiling and walls?
Q: What are the benefits of using CineGrey 3D® (AT)/CineGrey 4D (AT) or CineGrey 5D® material in a dark room with white ceiling and walls?

Projecting on a matte white screen material in a dedicated Home Cinema, typically requires a dark room environment for a great theatrical experience. Matte White materials diffuse light in all directions since that is their nature. This means that light will scatter everywhere in the room. That is why a dedicated Home Cinema room should try to have as much black walls and light absorbing materials to reduce the amount of scattered light. This scattered light eventually reflects back to the projection image and degrading the contrast ratio, color, and black levels which affect the fidelity of the picture. The CineGrey 5D’s CLR/ALR technology allows the projector’s light to reflect back at the mirror opposite end. This greatly reduces the amount of light scatter and instead focuses the light to the viewer’s sweet spot. In addition, the black microscopic layers improve black levels and color purity to increase the contrast ratio vs a matte white screen material.

Q: Is the AcousticPro UHD/CineWhite A8K/CineGrey 4D AT/CineGrey 3D AT compatible with my 3D projector?
Q: Is the AcousticPro UHD compatible with my 3D projector?

The AcusticPro UHD/CineWhite A8K/CineGrey 4D AT/CineGrey 3D AT is compatible with Active 3D projectors.  As the screen is not polarized, it will not work with Passive 3D applications.

Q: How far should I place my speakers behind the CineWhite A8K/CineGrey 3D AT/CineGrey 4D AT and AcousticPro UHD (Acoustically Transparent) screen materials?

A projection screen mounted flush against the wall over a properly installed in-wall speaker will have a sufficient distance by itself. There will generally be about a 1” total distance between the speaker’s dust cap (depending on make/model) and the screen with a 5mm (.2”) spacing between an in-wall speaker’s grill and the AT screen material itself.

All acoustically transparent materials on the market today are light enough in thickness to allow sound to penetrate it with low-level attenuation (decrease in sound quality) but normally come at the cost of having considerable light loss as well. Elite’s AcousticPro 1080P3 acoustically transparent (AT) material is an exception to this rule.  It has an astonishingly fine (.01mm) micro-perforated texture that allows sound to breathe through the fabric with minimal attenuation. At the same time, it allows the video aspects of the material to perform on the same level as a typical matte-white (non-acoustic) material does. The ultra-fine perforations of the AcousticPro 1080P3 “AT” material allows it to be used with high resolution (4096×2160 pixel ratio)  projectors. A special reflective compound coats the surface of Elite’s 1080P acoustic material to compensate for light penetration by reflecting the brightness of the projected image. All these features come together to form a product with superior acoustic transparency that has just 1% light loss while presenting a neutral color temperature (6500°-7000° Kelvin). This is equivalent and in some cases, even surpassing in video performance to a standard matte white non-acoustic projection screen.
