Influence of High-resolution 4K Displays on Psychological State During Content Viewing

We experimentally investigated the influence of high-resolution images on viewers’ psychological state while viewing content at 4K and 2K on a 65-inch 4K TV. Their scores for “presence,” “relaxed,” “natural,” “liked,” “comfortable” and “precise” when viewing 4K scenic content were significantly higher than those for 2K content. Our results suggest that, when using a large (65-inch) screen, viewing 4K scenic content affords greater psychological refreshment and lower stress than when viewing similar material at 2K resolution.
