Start with the decision

Three questions narrow the field quickly

Is the room bright?

Ambient light can wash out contrast. Learn when a directional ALR surface is useful and when better light control may be enough.

What size actually fits?

Work backward from room width, viewing distance and the projector's geometry instead of choosing inches first.

PET crystal or Fresnel?

Compare two common UST-screen approaches by viewing cone, light rejection behavior, installation and practical trade-offs.
