315 Truth Lab: Is TV HDR technology useful?

TV is the home appliance product that we are most familiar with. As a display device that serves the user's vision, the most important indicators for evaluating TV products are focused on improving visual effects such as size, brightness, contrast, color gamut, and so on. In recent years, a technology called HDR has been incorporated into its own products by many TV brands because it can effectively improve display quality, and it is familiar to a wide range of consumers. The description of HDR technology in Baidu Encyclopedia is as follows: High-Dynamic Range (HDR) provides more dynamic range and image details than ordinary images, and can better reflect Visual effects in a real environment.
Although HDR's improvement on the picture has been recognized by many parties, will any HDR-enabled TV be able to improve its picture quality? Today's truth laboratory will take you to see.
The enhancement of HDR technology is mainly reflected in brightness, dark details, colors, and overall authenticity. Although there are many television products equipped with this technology, the effects they bring are very different. Since HDR content is produced in a high dynamic range, a qualified HDR TV must first have high brightness, outstanding light control technology and dark detail processing capabilities, and wide color gamut technology.
There is no doubt that HDR technology can actually improve image quality performance, but it is currently limited to high-end flagship models. HDR technology on mainstream HDR TVs does not make much sense. Although the emergence of HDR technology is revolutionary, it is also a very high starting point. . Through actual testing, it is found that the effect of upgrading HDR TV under RMB 10,000 is not obvious, and more is only equipped with HDR decoding chip.
