Product A suits spaces with uncontrolled ambient lighting where the optical ALR layer maintains contrast. Product B fits dedicated dark-room home theaters needing a brighter 1.3 gain output on a larger display. Your room lighting conditions dictate the best option.
Key Differences Between NothPJ Motorized Screens
Ambient Light Rejection
Edge: NothPJ 100-Inch Motorized Floor Rising ALR Screen
Product A uses a 7-layer Optical ALR surface. This structure blocks up to 85% of ambient light in well-lit rooms. It also provides a 20000:1 contrast ratio and 96.5% color saturation. Product B features a black-backed matte white PVC material. This surface blocks light penetration from behind, but it does not reject ambient room light. Instead, it is optimized for dark-room home theaters. If you plan to watch content with ambient room lighting on, the NothPJ 100-Inch Motorized Floor Rising ALR Screen gives you superior contrast retention and prevents washed-out colors.
Screen Gain and Brightness
Edge: NothPJ 120-Inch Motorized Floor Rising Screen
Product B provides a 1.3 peak gain rating. This higher gain reflects more light directly toward your seating area, producing up to 80% better image clarity than a flat white wall in dark spaces. In contrast, Product A features a 0.85 gain rating. This lower gain helps control glare and deepens black levels, but it reflects less overall projector light back to you. If you want maximum image brightness from your projector in a light-controlled theater room, the NothPJ 120-Inch Motorized Floor Rising Screen delivers the higher peak reflectivity you need.
Projector Compatibility
Edge: NothPJ 120-Inch Motorized Floor Rising Screen
Product B supports standard throw, short-throw, and ultra short throw projectors. It also specifies a wide 170-degree viewing angle, which maintains uniform brightness across broad seating arrangements. Product A lists compatibility for standard and ultra short throw projectors, but the published specifications do not explicitly include short-throw models. The data also omits a specific viewing angle measurement for this unit. Because it supports all three standard projector throw types and documents a 170-degree viewing field, the NothPJ 120-Inch Motorized Floor Rising Screen provides more versatile placement choices for your projection equipment.
Motor Features and Deployment
Edge: NothPJ 120-Inch Motorized Floor Rising Screen
Product A uses a quiet tubular motor that completes screen deployment in 30 seconds. It includes a USB trigger to synchronize screen rising and lowering with your projector power. Product B also includes a USB sync trigger, but it upgrades the hardware to an AI DC tubular motor system. This motor includes soft start and stop protection, AI position memory, a one-touch reset function, overheat protection, and worldwide voltage compatibility. Both models automate lifting, but the NothPJ 120-Inch Motorized Floor Rising Screen includes more advanced motor control and safety mechanisms.
Size and Case Options
Edge: NothPJ 100-Inch Motorized Floor Rising ALR Screen
Product A provides five total variation options across two casing colors. You can select screen sizes of 100 inches, 120 inches, or 130 inches, paired with either a black or white case. The 100-inch unit measures 98 inches wide by 69 inches high. Product B offers two total variations. You can choose between 100-inch and 120-inch diagonal sizes, and it comes in a white casing. The 120-inch model measures 113 inches wide by 77.2 inches high. The NothPJ 100-Inch Motorized Floor Rising ALR Screen offers greater flexibility for matching your room dimensions and aesthetic.

Frequently asked questions
What are the physical dimensions of these two motorized screens?
The 100-inch model measures 98 inches wide and 69 inches high. In comparison, the 120-inch version has a width of 113 inches and a height of 77.2 inches. You should measure your floor and ceiling clearance to verify which casing size fits your designated viewing area.
How do the screen materials differ between these two models?
The 100-inch version features an ALR surface, whereas the 120-inch model uses a Matte White screen material. An ALR screen rejects ambient room light for clearer images during daylight, while a matte white surface reflects light broadly and is suited for dark rooms where lighting is controlled.
What projector throw types work with each NothPJ screen?
Both models support ultra short throw projectors according to their specifications. The 100-inch unit pairs with ultra short throw or standard projection setups. The 120-inch matte white model provides broader projection compatibility, allowing you to use it with any projector throw type in dedicated dark-room setups.
Which screen works best if you cannot control the ambient light?
You should choose the 100-inch motorized floor rising model for rooms with daylight exposure or uncontrolled light. Its ALR material is built for bright spaces. The 120-inch matte white model is best for dark-room home theaters where you can turn off the lights completely.
Do both NothPJ motorized screens support 4K UHD content?
Yes, both screens support 4K UHD resolution. Whether you choose the 100-inch ALR version or the 120-inch matte white display, each surface preserves high-resolution 4K output from your projector. You can expect crisp detail and sharp image clarity across either motorized viewing surface.
What casing colors do these NothPJ motorized floor rising screens have?
The 100-inch ALR screen comes with a black housing, while the 120-inch model features a white housing. You can choose the unit that coordinates best with your room interior, furniture, or floor trim. Both models rise smoothly from their floor-based cases when deployed.
Do you need to drill into walls to install either screen?
No, neither screen requires permanent wall installation or wall drilling. Both units use a motorized floor-rising format. You place the housing directly on the floor or a low credenza, and the screen retracts upward when powered on, making them ideal for spaces where wall mounting is impractical.
