The first part, the TV, is actually the easier part.
To be HDR-compatible, the TV should be able to produce more light than a normal TV in certain areas of the image. This is basically just like
local dimming, but to an even greater range.
Tied in with HDR is wide color gamut, or WCG.
For years, TVs have been capable of a greater range of colors than what's possible in Blu-ray or HD downloads.
The problem is, you don't really want the TV just creating those colors willy-nilly. It's best left to the director to decide how they wants the colors of their movie or TV show to look, not a TV whose color expanding process might have been designed in a few days 6,000 miles from Hollywood. More on this in a moment.
Of course, making TVs brighter and more colorful costs money, and some HDR TVs will deliver better picture quality than others. Just because a TV is HDR-compatible doesn't necessarily mean it's going to outperform non-HDR TVs. The only thing the HDR label really means is that the TV will be able to display HDR movies and TV shows.
The content is the hard part. To truly look good, the HDR TV needs HDR content, which today is almost nonexistent. TV shows and movies with 4K resolution are rare enough, but HDR TV shows and movies are even rarer. Only Amazon has released any so far, and it consists of just a couple of shows and a handful of Sony films. Netflix has said it will offer HDR before the end of 2015, but no other content provider has yet announced HDR for the home.
Another source of HDR will be
physical discs. The
Ultra HD specification allows the discs to carry HDR versions, with Dolby Vision as an option.
