a ceiling light rejecting front projection material designed for tabletop mounted ultra-short throw projectors
StarBright® CLR® 5
Compatible Projection :
The StarBright® CLR® 5 (SBCLR® 5) features Ceiling Light Rejecting technology for bottom placed ultra-short throw front projection applications in moderate light room environments. The surface can reject (absorb) 80% of ambient light to combat the washout effect typically experienced using matte white surfaces. This allows projector presentations to achieve contrast-rich images with a wide viewing angle without compromising picture performance and delivering exceptional imagery.

Ceiling mounted UST projector will not work with CLR®/ CLR® 2/ CLR® 3 flipped upside down because the material is specifically oriented to reject “absorb” lighting from above. In addition it is designed to properly accept tabletop mounted UST projector light and direct it to the viewer’s sweet spot. If the material is flipped upside down and there is overhead light, that light will not be rejected but instead reflected which would degrade the picture quality. In addition, the ceiling mounted UST projector light will still not likely align properly with the human eye to deliver the ideal “sweet-spot” picture performance.

CLR®/CLR®2/CLR®3 and CineGrey 3D/5D are Ceiling Ambient Light Rejection Screen fabrics, however the CLR fabrics are especially designed for Ultra Short Throw (UST) Projectors to reject ambient light. The CineGrey 3D/5D are typically made for standard “long-throw” projectors and require the projected light (angle in) to reflect (angle out) at the same angle to the viewer’s eyes, “sweet spot”.
Ceiling mounted UST projectors will not even work with Starbright CLR® materials because the material is specifically orientated to reject “ceiling light” or any type of lighting from above. This means that the screen will reject any overhead light, even from a compatible projector. Theoretically, you could invert the Starbright CLR® material to match with an inverted UST projector but the alignment will still not likely align properly with the human eye to deliver the ideal “sweet-spot” picture performance.
Most ultra-short throw projectors despite claiming they can go up to a certain size, if they have a focus adjustment should be able to adjust the picture to 103” (if a 100” UST projector) or 123” (if a 120” UST projector) and fill in the entire screen area. In some cases, certain UST projectors that have a fixed focus lens can go up to 103” and 123” with minimal impact on the picture and allowing to fill in the screen size.
The steep light from an Ultra-Short Throw projector causes the halo effect and can spill light around the frame. There is no way to solve it, but it can be mitigated by painting your wall a darker color, or putting a velvet border around the screen frame.
