No viewing position in the horizontal plane should exceed how many degrees from the edge of the displayed image?

The correct choice indicates that no viewing position in the horizontal plane should exceed 60 degrees from the edge of the displayed image. This recommendation is grounded in the principles of human visual perception and optimal viewing angles, which suggest that viewers should be placed within a certain range to ensure the best possible experience.

When viewers are positioned within 60 degrees of the edge of the screen, they can enjoy a more immersive experience, as this angle provides a good balance between visibility and comfort. Beyond this angle, viewers may experience distortions, reduced contrast, and limited detail, leading to a lower quality viewing experience.

In audiovisual design, maintaining proper viewing angles is essential for presentations, home theaters, or any facility that relies on visual content. This ensures that all viewers can receive an equitable experience regardless of their specific seating arrangement. Therefore, adhering to the 60-degree rule helps to establish guidelines for seating layouts and screen placements that optimize engagement and viewer satisfaction.
