Why the VIVIDSTORM UST ALR Floor Rising Screen is the Ultimate Home Theater Choice
[Expert Review: Verified by Japanese Tech Blogger "Omokichi Papa" | オモキチパパ推薦]
As the manufacturer of VIVIDSTORM UST ALR Floor Rising Screens, we are thrilled to share an in-depth review from renowned Japanese home theater expert, Omokichi Papa. After testing our technology, he declared it:
"The only screen you’ll ever need for ultra-short throw projectors (超短焦点プロジェクター専用スクリーンの正解)."
Ready to see how it performed? Here are the real-world test results.

VIVIDSTORM's UST ALR screen:
1️⃣ UST ALR Technology: Defeating Ambient Light
Most home cinemas struggle in bright living rooms. Our UST ALR (Ambient Light Rejecting) material is specifically engineered to reject 85% of ambient light, ensuring your image doesn't wash out.

Omokichi Papa’s Verdict: "The difference between a white wall and the VIVIDSTORM screen in daylight was night and day."
Vividstorm's UST ALR screen:
| Scenario | White Wall Performance | VIVIDSTORM ALR Screen |
| Nighttime (Dark Room) | Acceptable, clean image. | +20% Brilliance, deeper contrast, and vibrant colors. |
| Daytime (Bright Room) | Washed-out, hazy, and full of window glare. | Crisp 4K HDR visuals; "Theater-worthy" clarity. |
2️⃣ Perfect Flatness: The Power of Tab-Tension
Ultra-short throw projectors emit light at an extreme angle. Even a tiny wrinkle on a screen causes huge image warping.
VIVIDSTORM achieves Perfect Flatness (完璧な平面性) through:
-
Side Tension Wires: Constantly pull the screen surface to eliminate sagging.
-
Aluminum Housing: Provides a stable base that ensures zero wobble at full height.
-
No Distortion: The projected image remains geometrically perfect from edge to edge.
- The Science: Microscopic slit structures absorb ceiling light while precisely reflecting the projector's light from below toward the viewer.
3️⃣ VIVIDSTORM S PRO – Full Specifications
Our floor-rising design (床置き型) means Zero Installation (工事不要). It is the perfect solution for renters or luxury living rooms where ceiling mounting isn't an option.

4️⃣ Layout & Placement Tips: How to Avoid Mistakes
Choosing the right size (100インチ vs 120インチ) depends on your space. "Bigger" isn't always better—the most comfortable experience comes from the right fit.
Pro Layout Guide (Based on 84" Screen): To achieve an 84-inch image with a projector like the Aladdin Marca, you need a Total Depth of 56cm:
-
15cm (Wall-to-screen gap)
-
15cm (Projection throw distance)
-
26cm (Projector depth)
Always adjust your setup according to your specific projector’s throw distance.
