How's HDR Different than 4K?
Another popular term before HDR was the trend of 4K as the new pinnacle of image quality. So what’s the difference between 4K and HDR?
4K (or Ultra High Definition) refers to a specific resolution value (3840 pixels wide by 2160 pixels tall). A display cannot be 4K unless it hits the exact height and width defined in the standard.
HDR on the other hand, produces more colors within pixels and can be implemented regardless of resolution. Simply put, the shift to 4K was about providing more pixels. The shift to HDR is about providing better pixels.
