Projection guide
ALR screens and UST projectors
Ask GLMedia about the combination of ALR screen, UST projector, and room conditions: exact material, orientation, placement, and lighting alternatives.
Planning criteria
With the date, location, and intended use, we can review which equipment and combination can be offered. You can inquire before measurements, drawings, or the final schedule are ready.
The surface must accept projector light from its planned position and provide a usable audience image. ALR or CLR labels do not replace the exact material datasheet.
We can review photos, model, and space before screen selection. Compare controlling room light as an option too.
The inquiry can cover a screen and projector, installation, configuration, or review of an existing assembly. We separate surface, optics, placement, and required tasks when preparing the proposal, with scope and availability to be confirmed.
System decisions
- Exact material
- Record full name and variant. Do not interchange materials based on similar acronyms or color.
- Optical geometry
- Relate lens, screen, and viewers to the documented orientation. Lighting positions also require checking.
- Actual result
- Test uniformity, reflections, and readability from planned seats. A photo from another room does not establish performance.
- Alternatives to compare
- We can review a surface compatible with the planned position, another projector location, or changes to room lighting. Each alternative must retain supported optics and mounting; the ALR label does not make that choice.
What to share
Share projector, lens, screen material, image width, and planned positions.
Identify lighting and audience positions. If screen selection is pending, we can prepare conditions to check.
If the surface is unidentified, send a label photo or material code and a photo of its planned location. Tell us which lights must stay on and where viewers will sit; we can start there before selecting a model.
Preparing the comparison
- Check material compatibility: the current CineGrey 3D page excludes short and ultra-short throw. Do not generalize its conditions to every ALR surface.
- StarBright CLR is documented for tabletop UST placement below the screen. Check orientation labels and supported position; flipping material is not a generic solution.
- Compare options in the same room with the same content, tracking which lights remain on.
- Check aspect ratio, focus, and projector mounting separately. A compatible surface does not correct out-of-range geometry.
- Compare the same content, screen location, and lighting that must remain on. Check central and side audience positions and record readability, reflections, and uniformity before choosing the combination for the proposal.
Three technical questions
Does every ALR screen work with UST?
The material needs explicit compatibility with the selected lens and position. Some light-rejecting surfaces target conventional throw, others UST.
Does every UST require an ALR screen?
Selection depends on supported material, light, placement, and desired result. We can compare a compatible surface with lighting control against a specific optical solution without prescribing ALR solely from UST labeling.
Can I mount the projector above and flip any surface?
Check the exact combination. The Aeon CLR manual with StarBright CLR specifies tabletop UST; do not transfer that surface to another position by assumption.
Checks to guide decisions
| Symptom | Check | What it helps distinguish |
|---|---|---|
| Dark or uneven image | Material, orientation, and lens position. | Compatibility. |
| Distracting reflections | Light and audience views. | Site conditions. |
| Similar acronyms, different result | Full surface code. | Variant. |
Installation and limits
Follow exact-material mounting and care instructions; do not copy attachment or cleaning from another fabric.
Keep identification and test results. A lens, location, or surface change requires reviewing the affected combination.
Sources and context
Official model-specific documentation. Check variant, accessories, and conditions before applying settings or calculations.
