HDR will improve the quality of traditional radio and television from three aspects: brightness (usually expressed in nit), color gamut (the range of colors that can be displayed), and color depth (indicating the number of colors in the same gamut). . This requires both software support and hardware-supported technologies.
Mainly speaking about the current two mainstream standards for HDR technology, Dolby Vision (Dolby Vision) and HDR10, they were proposed by Dolby and the American Consumer Electronics Association. 
Both are the mainstream standards. From the aspect of picture quality, the native Dolby Vision supports 12-bit color depth, adopts dynamic metadata optimization method, and has stronger ability to restore the picture than HDR10, and the picture color and the contrast of light and shade are more accurate;
From the perspective of wide application, HDR10 is more open to users because it is an open standard and users are more likely to enjoy the content of HDR10. However, Dolby Vision TV is backward compatible with the HDR10 standard.
Therefore, overall, the current HDR TV is limited by hardware and is only a short-term solution to achieve HDR quality. More so-called “HDR TV†only supports HDR10 decoding, but it still has better picture quality than ordinary TV. At the same time, the HDR source will be gradually popularized as a 4K source, and will be applied to live signals in the future.
However, some TV manufacturers have only made improvements in color gamut, color depth, and brightness, and it is wrong to become HDR TV. At the same time, it is necessary to understand HDR10 as a standard for constant HDR television.
For 4KHDR TVs, LeTV Ultra 4uMax85 supports both HDR and Dolby Vision, 448-zone dynamic backlight ultra-fine light control, peak brightness at least 800nit, greater than 90% DCI-P3 color gamut standard, 10bit color depth panel, picture quality is great . 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
Briefly introduce it, HDR (High Dynamic Range) high dynamic range image, the main significance of this technology is that it shows higher peak brightness, lower dark field brightness, and wider color gamut than traditional broadcast television images. . With HDR, you can see both the shadows and the details of the highlights. The sun will not be as dazzling, the colors will be fuller and truer, and the gradient of the hue will be more delicate. In general, HDR will present more natural and realistic images.
