Projector Screen Manual 200 x 200 cm ( 78 by 78 inch)

A manual projector screen with dimensions of 200 x 200 cm (78 x 78 inches) is a type of projection screen that provides a large and square projection surface for displaying images and videos from a projector. Manual screens are manually operated, allowing you to pull them down when needed and retract them into a housing when not in use. Here’s a description of a typical manual projector screen of this size:

1. Screen Size: The screen has a square aspect ratio with a total diagonal size of 200 cm (78 inches). This size offers a significant viewing area, making it suitable for larger audiences and venues.
2. Manual Pull-Down Mechanism: The screen is operated manually by pulling it down from a cylindrical housing, which is usually mounted on a wall or ceiling. When not in use, it can be retracted back into the housing to save space and protect the screen.
3. Screen Material: The screen material is typically matte white or a similar neutral color, designed to provide a flat and smooth surface for projection. Matte surfaces reduce glare and reflection, ensuring better image quality.
4. Aspect Ratio: As a square screen, it often has an aspect ratio of 1:1, which means it can display both standard 4:3 and widescreen 16:9 content with black bars on the top and bottom or sides, depending on the content’s aspect ratio.
5. Viewing Angle: The screen material usually has a wide viewing angle, allowing the audience to view the projected content clearly from various positions within the room.
6. Mounting Options: The housing of the screen can be mounted on the wall or ceiling using brackets or hardware provided with the screen. Some screens may offer adjustable mounting options to accommodate different installation preferences.
7. Screen Tensioning: High-quality manual projector screens may feature a tensioning system to keep the screen flat and wrinkle-free, ensuring a smooth and distortion-free image.
8. Black Borders: Many manual screens have black borders around the viewing area to enhance perceived image contrast and provide a professional look.
9. Ease of Use: Manual projector screens are straightforward to operate and do not require any electrical connections or remote control. They are typically pulled down and locked into position using a pull cord or handle, and they can be retracted by releasing a locking mechanism.
10. Versatile Use: These screens are suitable for various applications, including home theaters, business presentations, educational purposes, and larger venues like conference rooms and auditoriums.
11. Maintenance: Manual projector screens are relatively low-maintenance, requiring occasional cleaning to remove dust or smudges from the screen surface.
12. Portability: Unlike fixed screens, manual screens are portable and can be easily moved or relocated if needed.
