The result is a brighter, more comfortable viewing experience throughout the day without sacrificing interior aesthetics. Whether watching movies, streaming TV, enjoying live sports or family entertainment, AmbientPro UST delivers a premium large-screen experience where people actually live.
- Optimized exclusively for UST laser projectors
- Up to 93% ambient light rejection

GUAP SERIES
Purpose-Built PET Crystal UST Surface
Engineered for contrast, color accuracy and comfortable viewing.
The precision PET Crystal optical surface is developed exclusively for UST projection. Its optical microstructure reflects projected light efficiently toward the audience while suppressing unwanted ambient light from above. Together with a 0.8 gain, wide 160° viewing angle and true 4K compatibility, AmbientPro UST provides excellent brightness uniformity, improved perceived black levels and natural color reproduction across the entire screen.
- PET Crystal optical material
- 4K Ultra HD compatible
- 160° viewing angle
- Consistent brightness and color
GUAP SERIES
Choose GUAP for Bright-Room UST Performance
Premium UST performance for bright rooms and refined viewing.
Select AmbientPro UST when the projector will be used in a modern living room or professional space where ceiling lights, windows and normal daily activity remain part of the environment. Its PET Crystal optical structure is optimized for UST geometry and prioritizes perceived contrast, image uniformity and comfortable viewing. For screens above 120 inches, or where maximum size is more important than fine optical performance, compare FlexScale UST. For a fully darkened room with a standard-throw projector, a conventional cinema surface may provide a more appropriate system balance.
- Best choice for premium UST installations from 80 to 120 inches
- Prioritize it when ambient-light control is limited or inconvenient
- Confirm UST projector geometry and screen centerline before ordering
- Compare GUFX for larger sizes and GTCP for controlled-light cinema rooms
Not recommended / limitations: Not recommended for standard- or long-throw projectors, outdoor use, or projects requiring a screen larger than the approved GUAP range.
Compare before selecting: Choose GUAP for the strongest premium UST picture performance up to 120 inches; choose GUFX when a larger image is more important.

AmbientPro UST for Bright Modern Living Spaces
Explore premium UST projection in bright residential interiors and professional presentation environments where contrast, color, normal room lighting and clean architectural integration all matter.
