UST Screen - Ultra Short Throw Projector Screen for Laser TV

Ultra-Short-Throw Projector Screen: Why a Special Surface is Indispensable

A screen for short-throw projectors differs fundamentally from classic projection surfaces. This is primarily due to the physics of projection: since the projector stands directly below the screen, the light hits the surface at an extremely steep angle. A conventional screen would reflect this light directly to the ceiling according to the physical law. The result would be a dull image and a brightly lit ceiling.

What exactly is an ultra-short-throw projector and why does it need help?

An ultra-short-throw (UST) projector projects image diagonals of 100 inches and more from just a few centimeters away. Due to this steep projection angle, even the smallest unevenness on the projection surface becomes mercilessly visible. A specialized short-throw projector screen is therefore designed to direct this light specifically to the viewer while simultaneously absorbing distracting light from above (e.g., ceiling lights).

Benefits of a High-Quality UST Screen

The biggest customer benefit of a UST screen is its usability in daylight. It transforms your projector into a full-fledged TV replacement. Thanks to its technological structure, you enjoy a high-contrast image with deep black levels, even when the room is not completely darkened.

Optimal Contrast Ratio Without Shadowing

A crucial advantage of the UST setup is that no one can walk through the image, thus eliminating shadowing. A high-quality ultra-short throw projector screen enhances this effect by providing an absolutely flat surface. Frame screens are particularly popular here, as they perfectly maintain the tension of the fabric, which is critical for UST projection, on a permanent basis.

Frequently Asked Questions about UST Projection Screens

Do I need a special screen for an ultra-short throw projector?

Yes, absolutely. Standard screens reflect light to the ceiling instead of to the viewer, which results in an extremely low-contrast image. Only a UST screen with a louvered structure directs the light correctly.

What is the difference between CLR and ALR screens for ultra-short throw projectors?

CLR (Ceiling Light Rejecting) is a specialized form of ALR. While ALR blocks light from all directions, CLR is precisely tuned to the steep angle of UST projectors to absorb ceiling light and reflect projector light from below.

Can I use an ultra-short throw projector on a wall without a screen?

It is possible, but not advisable. Even the smallest imperfections in the plaster will cast shadows due to the steep angle, distorting the image. Furthermore, the wall lacks the contrast-enhancing effect of a CLR screen fabric.

What is a sensible screen size for an ultra-short throw projector?

Most users opt for screen sizes between 100 and 120 inches. This offers the best balance between immersion and image brightness, as UST projectors deliver their optimal sharpness and brightness in this range.
