To produce the fine highlights that makes HDR images pop, physical display technologies like local dimming or OLED (more on the latter in a moment) really help. What is OLED and what can it do for your TV?.All TVs with 4K resolution, no matter how cheap, can typically show the full detail of 4K sources because they all have the same number of physical pixels. That's another key difference between HDR and 4K. The two aspects of HDR and WCG, namely brighter highlights and wider colors, aren't something just any TV can do. It will potentially look more realistic, with deeper and richer colors, and more visual "punch."īut, that's if the TV has the technology to show HDR as it's meant to be shown. The short version? An HDR TV, showing HDR content, can show brighter highlights and usually, a wider range of colors than a "normal" TV showing normal content. It's technically separate from 4K resolution, but almost all HDR TVs happen to be 4K TVs too. It's important to note that the HDR in TVs is very different from the HDR in your phone or camera. Related to HDR is WCG, or wide color gamut, which is also worth learning about. If you've heard of the term and want a explanation of what it's all about - and why it's cool - check out How HDR works. Just because a TV claims to be HDR-compatible, however, doesn't mean you'll be able to see high dynamic range content as it's meant to be seen. For several years HDR has only been available in expensive high-end TVs, but now it's making its way to midrange and even budget models. With the amount of high dynamic range video you can watch growing by the day, and more and more people recognizing the "HDR" abbreviation as something new (and potentially cool), TV manufacturers are jumping at the chance to show they're on top of this latest trend.
