the higher the dynamic range, the closer a photograph gets to real life.

Right now, UHD (or 4K) is the highest popular resolution for monitors, games, movies and TVs. There are a few devices with 5K or 8K resolutions.

HDR is basically talking about luminosity that is more dynamic than we’d see with standard resolution.

the dynamic range represents the "distance" (contrast) between white and the black in an image. In most cases, that distance is fairly narrow and is referred to as SDR (Standard Dynamic Range).

HDR is an expansion of the distance (contrast) between white and black in which bright whites can be captured and/or corrected so that they are more intense but don't overwhelm the rest of the image
