Decision guide
Do You Need an ALR Screen for a UST Projector?
Not always. The brighter and less controlled the room, the stronger the case becomes.
You can skip ALR when the room behaves like a theater
If you watch at night, use blackout shades, keep ceiling lights off and have dark room surfaces, a well-made matte white screen can preserve brightness and provide a neutral surface without the cost of specialized ALR material.
ALR earns its keep in real living rooms
Ceiling lights and daylight raise the black floor of a projected image. UST-oriented lenticular or Fresnel material manages the direction of that unwanted light so the image can retain more perceived contrast.
ALR is more compelling when…
- You watch during the day.
- Ceiling lights stay on.
- The room has pale reflective surfaces.
- The UST is replacing a living-room TV.
ALR is less necessary when…
- You can fully darken the room.
- Most viewing is at night.
- Maximum brightness is more important than ambient-light control.
- You are optimizing a dedicated theater.
Why the Black Series targets the first group
The Black Series combines a manufacturer-rated 0.6 gain with 95% ambient-light rejection and a 170° viewing angle. Those specs are aimed squarely at UST owners who need to protect contrast without forcing everyone into a narrow center seat.

FAQ
Do all UST projectors need an ALR screen?
No. A matte white screen can work well in a properly darkened room. UST-oriented ALR/CLR becomes more valuable as ceiling light and daylight increase.
Can I project on a white wall?
Yes, but wall flatness, color and ambient light can limit contrast and geometry. A purpose-built screen is more predictable.
Is 95% ALR a guarantee of daylight TV-like performance?
No. It is a manufacturer rating, and real results still depend on projector brightness, screen size, light direction and room conditions.
