两个实验的结果进行评估的HDTV节目的首选观看距离的报告。虽然屏幕亮度和场景中的运动程度会影响选择，但屏幕尺寸被发现是主要参数。观看距离偏好与图片高度（H）的比率倾向于随着显示器的尺寸而减小，并遵循双曲线定律。适用于高达32英寸的显示屏。优选的观看距离大于5 H;为了获得小于4 H的偏好，显示器大于70 in. are required.
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.
