HDMI 2.1: what is Dynamic HDR? 

Given the growing popularity of HDR, HDMI 2.1 bringing Dynamic HDR is perhaps the biggest news for home cinema aficionados. Essentially it means that the very finest values for depth, detail, brightness, contrast and wider colour gamuts can be sent to your TV on a much more  basis.
"Today, HDR is done by taking average values for HDR across an entire movie, so while you still get some benefit, it doesn't apply to each scene perfectly," says Park. "Dynamic HDR enables the HDR metadata to be applied as precisely as frame by frame, or more practically, scene by scene."
Frame by frame HDR would be massively time-consuming to produce, but scene by scene is feasible. Either way, HDR is about to be given a whole lot more impact.
