| HDR | In regards to consumer displays, 4K generally equates to a 3840x2160-resolution panel. This means the typical 4K screen will offer 3,840 horizontal pixels and 2,160 vertical pixels. When you multiply these numbers together, you get a panel with more than 8 million pixels. This is four times the pixel density of a traditional 1080p HD panel. |
