What is the role of TV box supporting HDR decoding?
The realization of the HDR effect follows the shortboard theory. For example, the relatively simple scene of using a TV box to connect to a TV requires the film source, box hardware, playback software, and display device to meet the requirements, and the HDR effect will not be displayed without one condition.
For HDR TV, it is not only necessary to have the hardware decoding capability of HDR video, but also the support of the TV panel, especially to increase the brightness, so as to improve the contrast of the picture.
The brightness of ordinary LCD TVs is generally around 300 nits. At present, the highest brightness of some HDR TVs can even reach 4000 nits. To achieve this result, you need to accurately control the brightness of the picture through the backlight zone and other image quality technologies, but there are only a few high-end TVs. In order to present such an effect.
Therefore, if the TV box supports HDR, the picture will be clearer, and the dynamic video display effect will be better. But there is also a prerequisite, that is, your TV needs to support HDR, so as to successfully achieve the best effect of dynamic video viewing.
