Make the big screen work in a real room.
Screen Signal helps you compare ambient-light-rejecting screens for ultra-short-throw projectors, with the NothingProjector PET Crystal Classic as our reference product.
100-inch PET Crystal ClassicWhy this screen gets compared so often.
A lower-gain lenticular surface can trade some peak brightness for stronger perceived black levels and ambient-light control in a UST setup.
That wide published viewing angle makes it a different proposition from narrower Fresnel screens that concentrate more light toward the center.
The manufacturer positions PET Crystal as a cost-conscious fixed-frame UST material for rooms where overhead and side light are part of daily use.
Three paths to the right screen.

Start with the UST screen buyer’s guide, then learn gain, lenticular vs Fresnel, installation and bright-room setup.
Open UST screen guides →Same goal, very different trade-offs.
Don’t choose by ALR percentage alone.
Screen geometry, gain, viewing cone, projector position, light direction and whether you can dedicate wall space all matter. The highest rejection figure is not automatically the best fit for every room.
