Élysium Screens Zenith Eclipse UST 110"

UST projectors, positioned a few centimeters from the wall, cast their beam at a steep angle that makes conventional screens (and white walls) unsuitable: unwanted reflections, amplified textures, washed-out contrast. The Zenith Eclipse UST addresses this optical constraint with an ALR screen material specifically designed to capture light coming from below while rejecting light from the ceiling and sides.

A screen that appears and disappears

The main advantage of a floor-rising motorized screen is its discreetness. The Zenith Eclipse UST deploys from its housing, rises in a few seconds thanks to a scissor mechanism, then retracts completely once the viewing session is over. This configuration suits living rooms and multipurpose spaces where a permanent fixed screen is not desirable.

The lateral cable tensioning system keeps the screen material perfectly flat once deployed, a critical point with UST projectors, which amplify the slightest ripple or surface curvature. The motorization is described as quiet, and deployment is controlled via the included remote control or a USB trigger that can synchronize the screen with the projector powering on.

The aircraft-grade aluminum housing

Élysium Screens has chosen a so-called “aircraft-grade” aluminum alloy housing, a term that refers to 6000 or 7000 series alloys, known for their strength-to-weight ratio. This choice is justified by the mechanical stress the housing undergoes: it must support the scissor mechanism, the tensioned screen material, and repeated deployment cycles without deforming. Aluminum also has the advantage of resisting humidity, which can extend the lifespan of the internal mechanism in less controlled environments.

How the Eclipse ALR screen material works

ALR (Ambient Light Rejecting) technology is based on a surface structure that treats light differently depending on its angle of incidence. On a UST screen, the material generally features a “sawtooth” or lenticular microstructure: the upper part of each micro-element, facing upward, absorbs light coming from the ceiling (the main source of light pollution in a living room), while the angled part reflects the projector beam toward the viewer.

The Eclipse screen material offers a 90% rejection rate for light coming from the ceiling and sides. In practical terms, this makes it possible to maintain usable contrast during the day with the curtains open, where a standard white screen would produce a washed-out image. The opaque black backing prevents any light from passing through the material from behind, which further enhances perceived blacks.

0.8 gain: the brightness/contrast compromise

A screen’s gain measures the amount of light reflected back toward the viewer compared to a reference surface (gain 1.0). With a gain of 0.8, the Eclipse screen material reflects slightly less light than a standard matte screen. This deliberate choice is explained by the very nature of ALR screens: the material that absorbs ambient light also absorbs part of the projector’s light.

In practice, a gain of 0.8 works well with UST projectors rated at 2500 lumens or more, which corresponds to most current laser models (Hisense, XGIMI, Formovie, AWOL Vision, etc.). Colors remain saturated, blacks gain depth, and the image retains a natural look without the “mirror” effect that high-gain screens can produce.

A wide viewing angle: 170°

The 170° viewing angle (that is, 85° on each side of the central axis) means the image remains visible and properly contrasted even for viewers seated off to the sides. This characteristic sets lenticular screens apart from Fresnel screens, which often offer better light rejection but a restricted viewing angle of around 50°, becoming problematic as soon as you move away from the center.

For family use where several people are watching from an angled sofa or side chairs, this wide angle avoids image degradation issues at the edges of the field.

4K, 8K, and HDR compatibility

The screen material is compatible with 4K and 8K Ultra HD content as well as HDR. In practice, this means the surface microstructure is fine enough not to create moiré or visible texture with high-resolution content. On some low-end ALR screens, the optical structure can interfere with definition and produce a “shimmering” effect or visible grain up close. Screens in this category generally use micrometer-pitch structures that remain invisible at normal viewing distance.

Installation and setup

The Zenith Eclipse UST is designed to be plug-and-play: place the housing, connect the power, synchronize the remote control. The manufacturer claims installation in just a few minutes, which matches what is typically seen with competing floor-rising motorized screens.

A few points deserve attention. The housing must be perfectly aligned with the UST projector, which projects from below at a precise angle. A shift of a few centimeters can create geometric image distortion. Most UST projectors have keystone correction and four-corner adjustment, but good initial physical alignment remains preferable.
