a ceiling light rejecting front projection material designed for tabletop mounted ultra-short throw projectors

CLR® 3

Ambient Light Rejecting Screens

The CLR® 3 is a ceiling ambient light rejecting front projection material designed specifically for tabletop-mounted ultra-short throw projectors that rejects the washout effects of room lighting. CLR® 3 is specially created using optical microstructures to absorb or “reject” up to 90% of overhead lighting while producing exceptional image brightness, color saturation and contrast for superior picture performance. All while providing a large-screen performance in the close quarters of most residential or even training environments.

What are the benefits of using a Ceiling Ambient Light Rejecting UST material vs. a Flat Panel TV

  • CLR® 3 (Ceiling Light Rejecting) material absorbs 90% of overhead lighting
  • Improves color saturation and black levels under ambient light conditions
  • 75x contrast improvement over standard matte white screens in ambient light room environments
  • Black-backing (non-opaque) enhances image brightness
  • Project from a short distance without shadowing the picture
  • 170° viewing angle (85° L/R)
  • Micro-serriform optical structure filters out ceiling light for superior picture quality
  • Designed for tabletop ultra-short throw projectors
  • 4K/8K Ultra HD Ready

Q: I plan to purchase a CLR®/ CLR®2/ CLR® 3 material, but want to use a ceiling mounted UST projector. Can I flip and install the CLR/CLR2/CLR3 upside down to make this work?
Q: I plan to purchase a CLR®/ CLR®2/ CLR® 3 material, but want to use a ceiling mounted UST projector. Can I flip and install the CLR/CLR2/CLR3 upside down to make this work?

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.

Q: I have a new UST projector in my multi-purpose room with very good light control. Considering to buy a StarBright CLR®/CLR® 2/CLR® 3 or CineGrey 3D/5D® screen. What is the difference?
Q: I have a new UST projector in my multi-purpose room with very good light control. Considering to buy a StarBright CLR®/CLR® 2/CLR® 3 or CineGrey 3D/5D® screen. What is the difference?

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”.

Q: How about using any “CLR/ALR” (Cinegrey®3D/5D or Starbright CLR®/CLR® 2/CLR® 3) with a ceiling-installed UST/ST projector?
Q: How about using any “CLR/ALR” (Cinegrey®3D/5D or Starbright CLR®/CLR® 2/CLR® 3) with a ceiling-installed UST/ST projector?

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.

Q: I’d like to buy an Aeon CLR® 3 screen but my UST projector is 120 inches. I notice that your screens are oversized by a few inches such as 103” versus 100” or 123” vs 120”. In my case for example, I do not want an empty screen section, but the image to go all the way to the border of the screen. Can you advise?

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.

Q: I own an Aeon CLR/CLR2/CLR 3 fixed frame screen and notice a halo effect/light spill around the UST screen. How can I remedy this?
Q: I own an Aeon CLR/CLR2/CLR 3 fixed frame screen and notice a halo effect/light spill around the UST screen. How can I remedy this?

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.
