[Verified by Tech Blogger "Omokichi Papa"]

As the manufacturer of VIVIDSTORM UST ALR Floor Rising Screens, we’re thrilled to share an in-depth review from Japanese home theater expert Omokichi Papa, who declared our product "the only screen you’ll ever need for ultra-short throw projectors."

Ready to see how it performed? Here are the test results!

1️⃣ ALR Technology That Rejects Ambient Light

• The UST ALR screen rejects 85% of ambient light while precisely reflecting projector light toward viewers.

• "The difference between white wall and the VIVIDSTORM screen in daylight was night and day." — Omokichi Papa

In-Depth Comparison: White Wall vs. Vividstorm UST ALR Screen

White wall

VIVIDSTORM's UST ALR screen:

Nighttime Comparison (Pitch-Black Room)

Even on a White wall , the projected image looks impressively clean—proof that high-end projectors perform well on plain surfaces.

But the screen delivers:
✔ Enhanced color vibrancy (though subtle in photos)
✔ Deeper contrast

Verdict: While walls work in dark rooms, the screen unlocks that extra 20% brilliance.

Daytime Comparison (Bright Living Room)

Vividstorm's UST ALR screen:

Daytime Showdown: Screen vs. Wall in Bright Light

The difference this time was stark—unlike the nighttime test.

White wall results:
✖ Washed-out, hazy image (details become hard to distinguish)
✖ Severe glare from windows/lighting

Vividstorm screen results:
✔ Remarkably crisp visuals (sharp enough for 4K HDR content)
✔ Active light rejection maintains contrast

Real assessment results: The screen transforms "unwatchable" daylight projections into theater-worthy clarity.

 

Perfect Flatness Achieved with Left and Right Tension Wires

The "tension wires" installed on both sides of the screen perform exceptionally well. These wires constantly and evenly pull the screen surface, maintaining flawless flatness without wrinkles or sagging.

Line Tension

Ultra-short-throw projectors emit light from below the screen, meaning even the slightest distortion on the screen surface would result in noticeable image warping. However, thanks to this tension structure, the projected image remains completely free from distortion.

Left and Right Tension Wires

Ambien Light Rejecting Technology:Absorbing Ambient Light While Precisely Reflecting Projector Light!

The second breakthrough of Vividstorm screens lies in this proprietary screen material. Its surface incorporates microscopic slit structures - nearly invisible to the naked eye - that embody our ALR (Ambient Light Rejecting) technology, enabling crystal-clear images even in brightly lit environments.

This innovative structure performs dual functions:

1. Effectively absorbing ambient light from ceiling fixtures and sunlight

2. Selectively reflecting only the projector's light from below directly toward viewers

The result? Even in daytime living room conditions, you'll experience:

• Exceptional contrast ratios

• True deep black levels

• Vibrant, distortion-free image quality

[Ultra Important] How to Avoid Mistakes: Key Considerations for Ultra Short Throw Projector and Screen Placement & Recommended Layout Tips

How to Choose the Right Size Based on Your Space – Detailed Recommendations Are Provided in the Table Below:

As mentioned above, Aladdin Marca can project a large screen of 80 to 120 inches if it is 15 to 33 cm away from the wall.

For an 84-inch screen and UST projector setup, the total depth needed is 56 cm, which includes: 15 cm (wall-to-screen gap) + 15 cm (projection distance) + 26 cm (projector depth).

Adjust the setup according to the throw distance of your specific projector.

80'' VS 100 ''—which one to choose? This has always been a debated question. So how should we decide?

When selecting the size, you need to consider the dimensions of your space—bigger isn’t always better. The most comfortable experience comes from choosing the right fit.
