Abstract
Previous studies have suggested that image spatial resolution and contents have little effect on the preferred viewing distance (PVD) of TV. However, in future TV systems such as 4k and 8k TVs with a wide field of view and high spatial resolution, TV program production methods may change depending on the TV system parameters, and viewer behaviors including PVD may change accordingly. Here, we conducted two experiments with a TV program consisting of still images to show that PVD is shorter in the high spatial resolution TV than low spatial resolution TV.
