Fixed-frame UST screen with Black Grid ALR for brighter living-room cinema.
The Changhong CHiQ S-CK Series is a dedicated ambient-light-rejecting screen for ultra-short-throw projectors. Its Black Grid optical structure rejects overhead ambient light while reflecting projector light back towards the viewer, helping UST laser projectors deliver stronger contrast and colour in real-world rooms.
Designed for ultra-short-throw projection only
This screen is made for UST projector layouts, where the projector sits very close to the screen. It is not the correct choice for standard or long-throw projectors. For non-UST projectors, choose a long-throw ALR, white cinema or other suitable front-projection screen instead.
Black Grid ALR for ceiling-light rejection.
The S-CK optical lens structure uses multiple layers to reject angular light from above while reflecting UST projector light towards the viewer. This helps reduce the washed-out look that ordinary white screens can suffer in rooms with ambient light.
- Dedicated ambient-light-rejecting screen for UST projectors
- Black Grid surface designed to reject overhead ambient light
- Helps maintain image contrast and colour saturation
- Supports 4K and HDR front projection content
Fixed-frame flatness for UST geometry.
Ultra-short-throw projection is highly sensitive to screen flatness because the projector sits very close to the surface. The S-CK fixed-frame design keeps the viewing surface flat, reducing the risk of geometry distortion caused by small waves or curves.
- Fixed-frame construction for a stable projection surface
- Rollable screen material helps simplify transport and installation
- Ideal for permanent living-room or cinema-room UST setups
- Supplied with fixing kit and installation instruction
Purpose-built for UST laser projection
The S-CK screen is designed to work with ultra-short-throw projector light paths, helping laser TV systems look cleaner and more contrast-rich than they would on a normal white wall.
0.6 gain image balance
The 0.6 gain surface is designed to preserve brightness while improving perceived contrast compared with many lower-gain ALR materials.
Up to 20× contrast improvement
The S-CK optical structure is designed to reduce ambient light interference and improve contrast, helping details and colours appear more defined.
170° wide viewing angle
A wide viewing angle helps the picture remain enjoyable from side seating positions, making it suitable for family rooms and wider sofa layouts.
4K and HDR ready
The front-projection Black Grid surface is suitable for modern 4K UST projectors and HDR viewing when paired with the correct projector and room setup.
Rejects room light, reflects projector light
Black Grid ALR technology helps reject ceiling light and other off-axis ambient light while reflecting the UST projector image back to the viewer.

Before ordering
For the best result, confirm your projector model, image size, screen height, wall width, installation position and seating distance before purchase. UST screens require accurate positioning because small changes in height and distance can affect image geometry.
- Confirm whether you need 100″ or 120″
- Check wall width and projector throw requirements
- Use with an ultra-short-throw projector only
