Product Overview

The Optoma UHZ35ST is designed for enthusiasts who want a serious cinematic image without needing a long room or ceiling mount far from the screen. Its short-throw lens makes it ideal for living rooms and dedicated media spaces where seating and furniture limit projector placement.

Optoma’s laser light source brings stable brightness over time and eliminates the recurring cost and downtime of lamp changes. The compact chassis and external power supply also simplify installation and day-to-day reliability.

Viewing Experience

The UHZ35ST delivers a crisp, high-contrast and energetic image with strong perceived punch. Bright scenes look vibrant and clean, while darker content benefits from the projector’s high dynamic contrast and stable laser output. Motion is smooth and responsive, which is especially noticeable for sports and fast-paced films.

For gaming, the combination of high refresh support (up to 240Hz at 1080p) and extremely low input lag gives a more immediate, connected feel—ideal for competitive titles, racing games and action-heavy gameplay.

Room Size & Screen Size Guidance

Thanks to the short-throw lens, the UHZ35ST is built for small to medium rooms where you still want a large image. It supports screen sizes from 36" to 300", with a projection distance range of 0.4m to 3.3m depending on image size.

• Smaller rooms: achieve a cinematic image without placing the projector far behind the seating
