Projection screen SBOX PSA-4:3-120-2, format 4:3, viewing area 240×180 cm

SBOX PSA-4:3-120-2 is a fixed-frame projection screen with a 4:3 aspect ratio and a viewing area of 240×180 cm. The screen is intended for use in presentations, classrooms and home cinemas where a standard 4:3 format is required. It provides a flat, uniform surface for projection and can be mounted to a wall or ceiling to create a permanent, reliable projection surface.

Advantages

The fixed-frame construction keeps the projection surface flat and tensioned, preventing waves and wrinkles that can distort the image. A 4:3 format and large viewing area support classic presentation and educational content without cropping. Wall or ceiling mounting options make installation flexible for different room layouts. The smooth white surface is designed for consistent light reflection and accurate color reproduction under typical projector brightness levels.

Suitable for

• Classroom lectures and school auditoriums
• Business presentations and conference rooms
• Home cinema rooms with standard-format content
• Training centers and seminar halls

How to use

Position the screen on a flat wall or mount it from the ceiling at a height that provides comfortable viewing for the audience. Align the projector to the center of the screen and adjust projector zoom and focus until the projected image fills the 240×180 cm viewing area without overspill. Use projector keystone or lens shift features if needed to correct minor alignment issues. For permanent installations, secure the frame according to mounting instructions and check that the screen surface remains taut and free of contamination.

Recommendations

For best image quality, use a projector with sufficient lumen output for the room size and ambient light level; reduce ambient light when possible. Maintain a clear viewing zone by placing seating at appropriate distances relative to the screen size, and periodically clean the surface with a soft, dry cloth to avoid scratching or staining.
