HDR is still a developing technology, and it's easy to be confused by it. There are two major HDR standards out there with commercially available content: HDR 10 and Dolby Vision. HDR 10 is an open platform that uses 10-bit color values. The UHD Alliance certifies televisions that meet the HDR 10 standard, along with minimum brightness and contrast ratios, as UltraHD Premium. Dolby Vision is a closed standard used by Dolby, which supports 12-bit color and determines ranges in the signal it provides to a display on the fly, based on the display itself and the needs of the scene. Televisions that support Dolby Vision will note so on their packaging.
HDR content is even more rare than UHD content, but it's becoming increasingly available. Ultra HD Blu-ray uses HDR 10, and Netflix and Vudu have started offering Dolby Vision films and shows digitally. Whether one standard is better than the other is difficult to determine at this point; HDR 10 uses more concrete values and is easier to technically evaluate, but Dolby Vision is designed to specifically fit the needs and limits of whatever television you use. No matter which you use, HDR-capable televisions can produce a better picture than TVs that don't support the wider color gamuts or increased range of luminance information.
What Screen Size Should I Get?
A big TV that's too close can be just as uncomfortable to watch as a small one that's too far away, so don't assume that the biggest screen available is the best choice. There are a few different rules of thumb regarding TV screen size based on your distance from it. Generally, the distance of your couch to your TV should be between 1.2 and 1.6 times the diagonal measurement of your screen. So if your couch is six feet away from your screen, you can comfortably watch an TV between 42 and 60 inches. If your couch is five feet away, a 37- to 52-inch screen should work well.
