What are 4K and HDR?
A 4K picture has a resolution of about 8,290,000 pixels, which is four times that of a full high definition (2K). Even when viewed on a large screen, it achieves high-definition picture quality down to the smallest details and reproduces realistic details and textures.
Note: 4K has higher picture quality than high definition (HD) and is also referred to as Ultra HD (UHD).

HDR (High Dynamic Range) can render brightness in a range wider than normal pictures. The higher standard of brightness that can be displayed allows for high-contrast pictures, and detailed color renders.
