HDR in the context of 4K TVs

Eh Daily has an article titled What is HDR and Why is it Important in 4K TVs?.

This article provides an important overview of why one should be considering the dynamic range of TV and not only its resolution.

All other things being equal, we would rather have a 1080P TV with a high dynamic range than a 4K TV with a mediocre dynamic range.  However, there is no reason why we can’t have both 4K and HDR other than the currently prohibitive pricing.
