Studies of the Influence of Display Size and Picture Brightness on the Preferred Viewing Distance for HDTV Programs
Maurizio Ardito · SMPTE Journal · 1994
The results of two experiments carried out to evaluate the preferred viewing distance for HDTV programs are reported. Although screen brightness and the degree of movement in the scene can influence the choice, screen size was found to be the dominant parameter. The ratio of the viewing distance preferences to the picture height (H) tends to decrease with the size of the display and follows a hyperbolic law. For displays up to 32 in. the preferred viewing distance is greater than 5 H; to obtain preferences smaller than 4 H, displays greater than 70 in. are required.
