VIVIDSTORM PRO vs S PRO: Drop-Down or Floor-Rising?

The PRO and S PRO use the same broad UST ALR concept but place the cassette on opposite sides of the image. The PRO hangs above and drops down. The S PRO sits below and rises up. That seemingly simple difference changes drilling, furniture, cable routing, safety and room aesthetics.

Specifications are drawn from current manufacturer/retailer listings checked in September 2026. Re-check the live product page before ordering because models, inclusions and regional availability can change.

Choose the cassette location first

The PRO works when you can mount a long housing securely to a wall or ceiling. It keeps the floor and furniture clear but requires drilling and overhead support. The S PRO is attractive when you want plug-and-play positioning on a console or floor with minimal wall work, but its housing remains physically present below the image.

Shared optical baseline

Current listings show both families using UST ALR/CLR material at 0.6 gain with a wide 170° viewing angle. That means the buying decision is often architectural rather than a search for a dramatically different image character. Confirm the exact material revision for the model and year you are buying.

Size range

The PRO is listed from 84 to 120 inches. The S PRO is commonly listed from 72 to 120 inches, giving it a smaller 72-inch option. If your wall cannot support an 84-inch diagonal after accounting for furniture and projector geometry, the floor-rising line has more flexibility.

Everyday behavior

A drop-down screen keeps a cabinet surface available and can disappear nearly completely into the upper room line. A floor riser avoids overhead work and can move with furniture, but the case is long, heavy and visible. Children, pets and traffic flow may also affect which mechanical layout is easier to protect.
