Projector screen SBOX PSM-4/3-100-2 200×150 cm – 4:3 wall/ceiling projection screen

The SBOX PSM-4/3-100-2 is a fixed projection screen with a viewing area of 200×150 cm and a 4:3 aspect ratio, intended for wall or ceiling installation. The screen provides a flat, tensioned surface that improves image clarity and reduces artifacts from uneven surfaces. Its substantial size makes it suitable for medium to large rooms where clear, consistent projection is required for presentations, lectures or video playback.

Advantages

The matte white projection surface ensures neutral color reproduction and wide viewing angles while minimizing hotspots. The robust frame and mounting design enable secure installation on walls or ceilings and help keep the screen aligned for repeatable, reliable use in educational, corporate, or home environments.

How to use

Measure and mark the desired installation location on the wall or ceiling, ensuring the screen is level and positioned at a suitable height for the audience. Install the mounting brackets into structural supports or appropriate anchors following local building standards. Attach the screen frame to the brackets and verify that the projection surface is flat and free of damage. Align the projector with the screen center, adjust focus and keystone or lens shift as required, and set projector output to match the 4:3 aspect ratio for optimal image fit.

Recommendations

For best image quality, position the projector so the projected image fills the 200×150 cm surface without significant overscan; use projector settings to match the 4:3 aspect ratio. Keep ambient lighting controlled to reduce glare and preserve contrast. Regularly inspect the frame and mounting hardware for stability and clean the matte surface with a soft, dry cloth or manufacturer-recommended cleaning method to avoid surface damage.
