RNT Projection Screen Motorised 100 Inches (4:3)

RNT Projection Screen Motorised 100 Inches (4:3)

This RNT motorised projection screen provides a 100-inch diagonal image in the 4:3 format, the classic shape for presentations, teaching material and data. In classrooms, training rooms and conference spaces the content is usually slides, documents and spreadsheets rather than cinema, and 4:3 matches that material without wasted screen area at the sides. The viewing area measures approximately 203 x 152 cm, large enough for text and diagrams to stay readable from the back of a mid-size room.

Motorised operation suits shared rooms especially well. At the end of a session the screen rolls up into its housing, out of sight and protected from dust, knocks and marker pens, leaving the wall free for a whiteboard or display. At the start of the next session it lowers to exactly the same position, so the projector alignment set on installation day keeps working. There are no dangling pull cords and nothing for students or visitors to tug on.

The flat matte surface spreads projector light evenly across the image, so slides look consistent from seats at the sides of the room as well as the centre. Black borders frame the image and improve perceived contrast, which helps charts and fine text hold up in rooms that cannot be fully darkened.

Key Features

• 100-inch diagonal screen in presentation-format 4:3
• Viewing area of approximately 203 x 152 cm
• Motorised operation raises and lowers the screen electrically
• Retracts fully into the housing, protected between sessions
• Flat matte surface for even brightness across wide seating
• Black borders improve perceived contrast for text and data
• Wall or ceiling mounting above the viewing position
• Suits classrooms, training rooms, conference spaces and CCTV monitoring

Getting the Installation Right

Mount the housing level and centred on the seating area, not simply centred on the wall or whiteboard: the audience’s axis is what matters. An off-centre screen forces keystone correction that softens fine text, which is exactly what presentation rooms cannot afford. Keep the screen surface centred on the projector lens, and position the case so the lowered image sits at a comfortable eye level for seated viewers.

Why 4:3 Still Matters

Universities, schools and institutions hold large libraries of 4:3 training content, document cameras output this shape, and CCTV monitoring walls commonly use it. Choosing the format that matches your content avoids letterboxing and uses the full brightness of the projector on the image itself. For movie-led home use, the 16:9 version of this screen is the better fit.

Care and Everyday Operation

A motorised screen asks little of its users between sessions. Keep the viewing surface fully retracted when the room is used for other purposes, since the housing shields the material from dust, sunlight and accidental contact. If the surface picks up marks, a soft, slightly damp cloth is usually sufficient; harsh cleaners can damage matte coatings. Periodically check that the case fixings remain tight and that nothing has been placed where it could obstruct the screen as it lowers. Operated this way, the screen presents the same flat, correctly positioned surface at every session, year after year, with no manual handling of the viewing material itself.
