The CineGrey 4D AT is an Acoustically Transparent front projection Ceiling Ambient Light Rejecting (ALR/CLR®) material that is perforated to allow sound to breathe through for speaker placement behind the screen. Its angular reflective properties are designed to work with standard throw projectors for proper reflection to the viewer’s sweet spot. The Ambient Light Rejecting technology rejects and absorbs off-axis lighting to provide contrast-rich images in any environment. The surface is precisely formulated to ensure optical image characteristics for high resolution projectors.
The CineGrey 4D AT is ISF Certified for accurate color reproduction in dark room environments to faithfully reproduce the content as the director intended.

Projector Placement for Angular-Reflective Screen
Notice to Installer:
Please use the following installation instructions to obtain superior optical performance from the ALR (Ambient Light Rejecting) Screen.
- Angular-Reflective material is not compatible with ultra/short-throw projectors
- Minimum lens throw ratio 1.5x image width
- Ambient light must not come from the same direction as the projector
Since angular-reflective means that the projected image will reflect at the mirror-opposite angle, it is important to position the projector so that the viewer will get the best possible image.
- Step 1: Establish the general “eye level” of the viewers
- Step 2: Set the appropriate projection level
- Step 3: Adjust the screen height level and projection angle
Input Angle (A) = Output Angle (B) aligns with the viewer’s angle
