What Is a Motorized Floor-Rising Screen?
A motorized floor-rising screen—often called an electric floor-rising screen or motorized lift screen—is a projection display device that houses its screen material inside a floor-level enclosure. With the press of a button (or automatically via projector trigger), the screen rises vertically from its housing, locks into position, and retracts back when not in use.
The core appeal is zero-installation freedom: no wall drilling, no ceiling mounting, no permanent structural changes. You simply plug it in and place it where you want it. This makes floor-rising screens ideal for renters, luxury apartments, or anyone who doesn't want to commit to permanent home theater modifications.
How It Works
An internal motor drives the screen upward from a low-profile floor case. Once fully extended, the mechanism locks automatically. High-end models include side tensioning systems (scissor-lift frames or tab-tensioning) to ensure the screen surface remains perfectly flat—critical for ultra-short-throw (UST) projection where even minor ripples distort the image. Many models feature wireless RF remote control, IR control, and USB trigger synchronization that automatically raises the screen when you power on your projector.
Core Performance Attributes of a Premium UST Floor-Rising Screen
Beyond the convenience of motorized rising, what truly defines a high-performance electric floor-rising screen? Here are the essentials:
| Attribute | What It Means |
|---|---|
| ALR/CLR Optical Microstructure | Linear black-grid or lenticular lenses that reflect projector light toward the viewer while absorbing overhead and side ambient light. Top-tier screens achieve 85–95% ambient light rejection. |
| UST-Optimized Light Path | The screen's optical structure is specifically tuned for the steep upward projection angle of UST projectors, ensuring light from the projector is captured efficiently while ceiling lights are rejected. |
| 0.6–0.8 Gain + Wide Color Gamut | The optimal gain range for UST ALR screens is 0.6–1.0—high enough for brightness but low enough to avoid hotspots and narrow viewing angles. Premium screens deliver 95%+ Rec.709 color gamut coverage for accurate, lifelike colors. |
| Multi-Layer Optical Composite Construction | Multiple laminated optical layers prevent warping, delamination, and deformation over time—essential for maintaining image quality years down the road. |
Screen Materials: From CBSP Black Grid to Premium HBST PET
CBSP Black-Grid ALR (Standard)
CBSP (Black Grid) is the most common ALR material for UST floor-rising screens. It uses a linear lenticular micro-structure—a black-grid pattern that absorbs overhead light while reflecting projector light toward the viewer. It delivers excellent ambient light rejection (typically 85–95%) and wide viewing angles (~160–170°).
Trade-off: Gain is typically capped at ~0.6, requiring a bright projector (2,500+ lumens) to maintain punch in well-lit rooms. CBSP is the industry standard for mid-tier electric floor-rising screens.
Premium HBST PET (NothingProjector Black Series)
Premium HBST PET is a superior material used in NothingProjector's Black Series. It builds on CBSP's foundation with enhanced optical clarity, better black levels, and superior durability. The "PET" (polyethylene terephthalate) base provides exceptional dimensional stability, while the advanced optical coating delivers:
- 95% ambient light rejection
- ST Carbon Black coating for deeper blacks and reduced reflection
- 170° ultra-wide viewing angle
- 4K/8K UHD resolution support
The HBST PET material in the NothingProjector Black Series is widely considered the most premium and costly ALR screen material available under €2,000.
High-End Multi-Layer Optical ALR (e.g., Black Diamond Fusion)
At the pinnacle of the market are materials like Screen Innovations' Black Diamond Fusion ALR—a multi-layer optical surface that achieves 1.0 gain, 160° viewing angle, and near-zero texture or laser speckle. These are zero-compromise materials for dedicated home theaters.
Price: A 120" Black Diamond Fusion ALR screen carries an MSRP of ~$5,000+.
Premium UST Electric Floor-Rising Screens: European & US Pricing

The NothingProjector Black Series Motorized Floor-Rising Screen was honored with the AVSForum 2025 Best Product Award—a testament to its exceptional value, build quality, and performance in real-world home theater environments.
What the Experts Are Saying
Roland (Simple Home Cinema)
“The NothingProjector Black Series delivers impressive performance for its price, with excellent build quality, strong ambient-light rejection, and a clean, high-contrast image.”
He particularly praised the ceiling light rejection as "genuinely first-rate"—the image appears to "float" even with downlights on. In dark conditions, the screen looks deep black with suppressed boundary reflections, delivering high perceived contrast.
HomeTechnology Review
“It's like having a movie theater that materializes on command.”
The reviewer highlighted the heavy, precisely engineered aluminum frame and the sleek housing that "virtually disappears" when not in use—measuring just 111.7″ wide and 6.4″ deep. The 72-pound unit ships quickly via DHL and delivers a premium disappearing home theater experience.
AVSForum Community
AVSForum members have consistently praised the Black Series for its superior black levels compared to competitors like AWOL, noting it appears brighter in light scenes and delivers better overall contrast in all lighting conditions. One member called it "the cheapest floor riser you can get in Europe" with excellent value for money.
The Hook Up (YouTube ALR Screen Comparison)
In a well-known ALR screen comparison, the NothingProjector Black Series earned 2nd Place for Speckle Reduction—a critical metric for laser projector users—while maintaining a highly competitive price point.
Floor-Rising vs. Tripod/Stand Screens: The Key Differences
| Feature | Motorized Floor-Rising Screen | Tripod/Stand Screen |
|---|---|---|
| Installation | Zero-drill, plug-and-play floor placement | Manual setup required; needs assembly each use |
| Flatness/Tensioning | Built-in motorized tensioning (scissor-lift or tab) for ripple-free surface | Often prone to wrinkles and waves without active tensioning |
| Storage/Retraction | Fully retracts into low-profile floor case; disappears when not in use | Remains partially assembled or requires folding; bulky storage |
| Portability | Heavy (~72 lbs)—not designed for frequent moving | Lightweight and portable—designed for travel |
| Aesthetics | Sleek, modern; looks like premium furniture | Functional but utilitarian; visible frame and legs |
| Price (120″ ALR) | $1,600–$5,000+ | $300–$800 |
| Motor Noise | Quiet but audible (~40–50 dB during operation) | Silent (manual operation) |
| Best For | Permanent or semi-permanent home theater setups, renters, luxury living spaces | Portable presentations, outdoor movies, temporary use |
