Previous studies have suggested that image resolution and contents have little effect on the preferred viewing
distance (PVD) of traditional TV systems. However, in future TV systems such as ultra-high-definition (8k) TVs, which are
expected to have a wide field of view and high spatial resolution, TV program production methods may change depending on
the system parameters, and viewer behaviors including PVD may change accordingly. Here we show that PVD is shorter in the
8k TV than the high-definition TV.
