The method used to calculate the farthest viewer's position for a video display is based on the DISCAS formulas. DISCAS stands for Distance, Image Size, Contrast, Acuity, and Source, and it provides a mathematical framework to determine viewer distances in relation to the size of a display.

This is essential for AV professionals when designing spaces for optimal viewing experiences, as it helps ensure that viewers can comfortably see and perceive the displayed content without straining their eyes. The formulas take into account factors like the resolution of the video display and the visual acuity of the audience to establish appropriate distance metrics.

Other methods, such as a video calibration tool, impedance meters, or light meters, serve specialized purposes in audiovisual setups but do not specifically address the calculation of viewer distances in relation to video display size and resolution.
