![]() Content is still in the early stages, however. An HDR TV that's HLG-compatible would understand what to do with the HLG signal and show that brighter information as a physically brighter part of the image (i.e. An SDR TV would see the HLG signal and think it was "normal," showing an image that had, perhaps better highlight detail. The horizontal axis is the physical brightness coming out of your television. The vertical axis is the signal, from broadcast, cable or satellite for example. It's part of the upcoming ATSC 3.0 standard.Ī graphical representation of an SDR and HLG signal. Like HDR10, HLG is likely better than SDR, but perhaps not quite the picture quality of the other HDR formats. Mainly, that's in terms of picture quality. Though as you can imagine, it's not without drawbacks. One signal that works on both older TVs and newer is a huge deal for broadcasters. Unlike the formats we've discussed so far, it's actually backward-compatible with SDR TVs. Hybrid Log Gamma was created by Britain's BBC and Japan's NHK. Not a huge issue, but something to keep in mind. That said, there is far less Dolby Vision content than there is HDR10 content. Content-wise, there's support from Sony, Universal, Paramount, Lionsgate and the Swiss of every format war, Warner, plus others. ![]() Some companies might only offer Dolby Vision support on certain models. Samsung is the biggest holdout, for reasons mentioned above. DolbyĪfter HDR10, this is the most popular HDR format, but that doesn't mean it's universal. This is an approximation, using two SDR images, of what you'd see if you placed an SDR and HDR TV side-by-side. It's impossible to show you want an HDR image looks like on your current device, since it's SDR. For larger companies (like certain Korean companies that begin with S), they don't need such assistance and would rather dump money into their own HDR format, thank you very much. So for some companies, this is an easy way to get their TVs to look better than perhaps they would on their own. On the plus side to that, Dolby will then show them how to make their TVs look best when showing DV content. The issue with DV is that companies have to pay Dolby to use it. Aspects of Dolby Vision, like how it handles dynamic metadata and color, are optional for HDR formatting in the upcoming ATSC 3.0. Streaming services like Netflix, Amazon, Vudu and Apple's iTunes support it, and you can find it on some Ultra HD Blu-rays. Like HDR10 Plus, it can have dynamic metadata. Potentially the best image quality of all the formatsĭolby Vision has made a big push for HDR.It's unlikely this will become the standard dynamic metadata HDR format, and it seems right now it's only giving Samsung an excuse not to include Dolby Vision on their TVs.įor more details, check out What is HDR10 Plus. Is the only hardware manufacturer supporting the format in the US, though TCL and Hisense support it in China. HDR content on an HDR TV can look far more punchy and vibrant than traditional content. Older content is now referred to as "SDR," or standard dynamic range. pretty much everything you've ever watched). Have the ability to display HDR content, which has more detail in the bright and dark areas of the image, for a greater "dynamic range" compared to non-HDR content (i.e. One format might look "better" than another on paper, but in the real world the biggest factors are the TV's overall performance and the content itself.Everything supports HDR10, but many TVs and sources will also have at least one of the other formats.Multiple HDR formats can exist in a single TV.It's not a full-fledged "format war," it's more like a slap fight.Here's a tour of the HDR landscape as it stands today. But knowing your way around the different formats is still worthwhile. In CNET's TV reviews, both the capabilities of the TV itself and the way HDR is used in the movie or TV show have a greater impact on image quality than the specific HDR format.
