Projekčná plocha SBOX PSM-4/3-120-2 240x180 cm projekčná plocha 4:3

SBOX PSM-4/3-120-2 is a fixed-frame projector screen with a 240 x 180 cm viewing area and a classic 4:3 aspect ratio. Designed for presentation and display tasks, the screen provides a uniform, matte surface intended to deliver clear image reproduction for slides, educational content and standard-definition video. The robust frame and tensioned projection surface ensure flatness and stable image geometry in meeting rooms, classrooms and dedicated media spaces.

Advantages

The fixed-frame design keeps the projection surface taut and wrinkle-free, improving focus and uniformity across the entire image area. The matte white surface reduces hot spots and reflections, which contributes to even light distribution and higher perceived contrast under controlled lighting. The 4:3 aspect ratio matches traditional presentation and educational formats, while the 240 x 180 cm size offers a large visible area suitable for medium to large rooms. The screen is constructed for repeated use, with a frame that supports easy wall mounting and maintains a consistent projection plane.

Suitable for

• Business presentations and meeting rooms
• Classroom instruction and lecture halls
• Training sessions and corporate seminars
• Home cinema setups using 4:3 content or legacy sources
• Public information displays and events

Key specifications

• Viewing area: 240 x 180 cm

How to use

Mount the frame securely to a flat wall using appropriate anchors for the wall material and the screen weight. Unpack the tensioned projection surface carefully to avoid creases; the surface should already be secured to the frame. Adjust projector placement and focus so the projected image fills the 240 x 180 cm area without significant overscan. Calibrate projector keystone and zoom settings as needed to match the 4:3 aspect ratio, and set room lighting to reduce ambient reflections for optimal image visibility.

Recommendations

For best results, use a projector with native 4:3 output or set the device to 4:3 mode. Position the projector at the manufacturer’s recommended distance for the projected image size, and maintain moderate, controllable room lighting to preserve contrast. Clean the matte surface gently with a soft, dry cloth; avoid abrasive cleaners or solvents that can damage the projection fabric.
