SBOX PSA-4:3-100-2 is a fixed projection screen measuring 200×150 cm with a 4:3 aspect ratio designed for clear, correctly framed projection in presentations, classrooms and home environments. The non-retractable format provides a stable, flat surface that maintains consistent image geometry for projectors configured to 4:3 output. Built as a ready-to-mount screen, it suits medium-sized rooms and delivers a large viewing area for slides, training content and standard-definition video sources.

Advantages

The fixed-frame surface ensures uniform tension and a flat projection plane, reducing wrinkles and hotspots. A 4:3 aspect ratio matches traditional presentation and education formats, simplifying projector alignment and avoiding unwanted cropping. The 200×150 cm size gives a substantial image area while remaining practical for mounting on walls in meeting rooms and classrooms. The screen material is optimized for even light distribution and predictable color rendering, supporting clear text and graphics.

Suitable for

• Business presentations and meeting rooms
• Classroom lectures and training facilities
• Home media rooms with 4:3 content or legacy equipment
• Exhibitions and demo areas requiring fixed-screen installation

Key specifications

• Visible screen size: 200 × 150 cm
• Aspect ratio: 4:3
• Screen type: fixed-frame / fixed-size projection screen
• Surface: matte projection material with even light diffusion
• Installation: wall-mount with frame supports for tensioned surface

How to use

Mount the SBOX PSA-4:3-100-2 on a flat, stable wall using appropriate anchors for the wall material. Ensure the center of the screen is aligned with the projector lens vertically to reduce keystone distortion. Connect and position the projector at a distance and zoom setting appropriate for a 200×150 cm image in 4:3 mode, then fine-tune focus and projector keystone or lens shift as needed. Regularly clean the projection surface with a dry, lint-free cloth to remove dust; avoid abrasive cleaners or excessive moisture.

Recommendations

For best results, pair the screen with a projector calibrated to 4:3 output and place ambient lighting under control to maintain contrast. Use wall anchors rated for the combined weight of the frame and screen, and confirm the mounting height supports comfortable viewing from the intended seating area.
