In the 4K publicity of the Main Street, the so-called HDR "high dynamic range" is only mentioned as an accessory. After all, compared to the high picture resolution, it is difficult to explain to the consumer what benefits the HDR has. However, aside from these gimmicks, the focus of the next TV war may be HDR, and Samsung and Sony have lost the upper hand.
Prior to HDR, the most important technological innovation in the TV market was 4K, bringing much higher resolution than the existing 1080p. However, the fact is that 4K does not play a role in improving the picture quality as much as we imagine. After all, if we keep the ideal viewing distance, 1080p movies are already quite clear.
HDR is different, it allows all parts of the image to ensure that there is a wealth of details and dynamic range, in people's view that is more realistic, more depth, more full and vivid images. However, the fact is that although the Ultra HD Alliance has designated HDR as a 4K standard, not all 4K TVs have HDR technology. If HDR does not show the details of the image, even if the resolution is high, it will be completely lost. Many people will say when evaluating 4K Blu-ray players: "If you want to maximize its potential, then you have to match a high-end TV supporting HDR." This shows the importance of HDR for picture quality performance.
Having said how important HDR is, you need to talk about the upcoming war. HDR technology currently has two major formats, HDR10 and Dolby Vision. Almost all HDR TVs support the HDR10 format. However, Samsung and Sony's TVs only support HDR10. We also don't see the shadow of Dolby Vision in the television products they launched this year.
Samsung and Sony are not deterring HDR technology. On the contrary, they have been highlighting the benefits of HDR and showing it around. The only reason to choose HDR10, Sony said that is because most of the HDR content is in this format, and HDR10 is also enough to bring the best viewing experience. As for Samsung, it is claimed that the open source of HDR10 gives them the opportunity to customize and optimize the experience.
From a technical point of view, there are many similarities between HDR10 and Dolby Vision, such as metadata processing rendering images. However, Dolby Vision is dynamic and can even perform frame-by-frame rendering, while HDR10 is relatively static and can only process content segment by segment.
However, the real problem is not in technology, because from the actual experience of people, the two formats on the high-end TV, the perception will not be decisively different. The problem is that vendors including LG, Vizio, and a large number of video streaming service providers can provide dual-format support. This has the advantage of enabling users to seamlessly access all HDR content without having to worry about supporting or not. If a content is exclusive to Dolby Vision, users of Sony and Samsung can only blink, at least until HDR10 is released.
As mentioned above, the key to the problem is not which format is better. The two formats of HDR 10 and Dolby Vision stand side by side, and in the future it is likely to cause inconsistencies in the content. At this time, products that can support both products show advantages. TVs are not like mobile phones. Users do not change every year. Instead, they use them for a long time. For such products, consumers naturally demand that the more universal it is, the better. The impact of HDR on image quality is obvious. If a high-end TV only supports half of them, I believe many consumers will consider it before starting.
