StarBright® CLR® 5

Matte grey was an earlier effort by projection screen manufacturers to enhance projector performance when projectors had limited performance ranges in need of a little help. Matte grey materials added a darker shade to projected images that would enhance black levels to a degree. The down side is that a projector with a high lumens output and interior light control was required. The next generation materials we offer now are CineGrey 3D / CineGrey 5D. The CineGray materials are ambient light rejecting. This means that the new materials will give you flat panel display brightness even with high levels of interior lighting. The old matte grey materials are washed out by interior lighting. Also, the Cinegrey series of ALR and ceiling light rejecting (CLR) screen materials give reference grade quality that is world class certified by the Imaging Science Foundation (ISF) for its professional grade abilities to provide accurate color rendition, contrast, and black/white dynamic range. The CineGrey 3D® has a wider diffusion range while the CineGrey 5D® is brighter. Comparing either CineGrey 3D/5D materials to the old matte grey is like comparing a couple of souped-up Ford Mustangs to a Model T.

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.
