Precision by Design: UST Projector Positioning
An ultra-short-throw (UST) projector can deliver an impressive picture, but only when it's positioned correctly. Yet conventional projector cabinets often leave owners adjusting their equipment to fit the furniture, rather than the other way around.
For Cinèst, rethinking that relationship became the startin g point for a new approach to UST projector positioning.
The Customer Insight That Changed Our Design
Cinèst entered the UST projector market with expertise in furniture design. Our first cabinet brought a more considered aesthetic to home theater spaces, but its functionality was similar to other cabinets on the market. It was designed to accommodate the projector, with little consideration for the precision required to position it.
Customer feedback revealed what we had overlooked. Some users couldn't align the image with their screens, while others found the projection path blocked by the cabinet. What seemed like isolated installation difficulties pointed to a more fundamental design limitation.
After speaking with nearly 100 users and consulting projector manufacturers, the Cinèst team began looking beyond the projector's dimensions to understand its optical requirements.

This insight changed our approach: the furniture shouldn't simply accommodate the projector. It should help the projector perform as intended.
Designed Around Throw Ratio for Better Screen Alignment
For a UST projector, precise positioning is essential to picture quality. Each model has a specific throw ratio that determines the distance needed to project a particular image size. A 100-inch image and a 120-inch image require different placement, while projector height and screen position introduce another set of variables.
Traditional sliding platforms typically adjust only the distance from the screen. If the projector sits too high or too low, users may resort to makeshift supports or digital keystone correction, which can reduce effective image detail.
Cinèst approached the problem from the projector's optical requirements rather than the cabinet's fixed dimensions. By allowing both horizontal depth and vertical height to be adjusted physically, we could help users align the image more accurately while reducing the need to sacrifice picture quality through digital correction.
Four-Way Adjustment Without Blocking the Projection Path
A height-adjustable platform seemed like the obvious solution. It could be added to our existing cabinet with relatively little modification. But early prototypes revealed that raising the projector could bring it into contact with the upper structure or cause the cabinet panels to obstruct the projected light.
The problem wasn't simply how far the projector could move.
It was how to give the projector enough freedom to move without letting the furniture interfere with the image.
Cinèst ultimately redesigned both the opening mechanism and the positioning platform. The upper panels move apart to the left and right, creating an unobstructed projection path, while the motorized platform moves the projector forward, backward, upward, and downward.
With 245 mm (9.6 in) of front-to-back travel, 100 mm (3.9 in) of vertical travel, and a maximum load capacity of 15 kg (33 lb), the platform is designed to accommodate a wider range of UST positioning requirements.
The result is more than an adjustable shelf. It is a coordinated design in which the cabinet makes room for the projector to reach the position its optics require.
Reinforcing the Opening Panels Without Limiting Movement
Cinèst's side-opening panels solved the problem of blocked projection light, but introduced an unexpected challenge. Without sufficient structural support, the cabinet's top surface began to sag when the panels closed. Creating more room for the projector had come at the expense of the furniture's stability.
The team returned to the structure, reinforcing the moving panels while preserving the open space the projector needed. More than ten cabinet prototypes were discarded as the design was repeatedly revised and tested. Integrating the movement with the electronics brought further rounds of refinement.
What began as a two-month development plan eventually took nearly a year, increasing costs by approximately 65% compared with the original approach. For Cinèst, the challenge was never simply to make the platform move. It was to make precision movement and furniture integrity work together, whether the projector was in use or hidden away.
Better Picture Quality Starts with Precise Positioning
The real value of four-way adjustment becomes clear when the picture reaches the screen.
With Cinèst's motorized positioning platform, users can adjust their UST projector's height and distance by remote control, bringing the projected image into closer alignment with the screen. The projector's own automatic screen-fitting and focus functions, where available, can then help complete the setup.
This sequence matters. Instead of relying heavily on digital keystone correction to compensate for an incorrect position, Cinèst helps users correct the alignment physically. Reducing unnecessary digital correction can help preserve more of the image's original detail and sharpness, allowing the projector to deliver a picture closer to its intended quality.
The same flexibility supports different UST models and makes future projector upgrades easier, subject to the equipment's dimensions and installation requirements.
For Cinèst, precision isn't about how far the platform can move. It's about how faithfully the projector can deliver the picture it was designed to produce.
