HDR TV is hard to distinguish HDR technology is not really HDR TV

With the drop in TV prices, the price of large-screen TVs can now be approachable. Not only does the screen size increase, but some television technologies also begin to penetrate downwards. 4K HDR TV is no longer just a high-end standard, but is also widely used in mid-range and even low-end products. But when you buy a TV and use it at home, HDR does not seem to improve the picture quality. Sometimes it makes the picture worse. True, you may be the victim of a false HDR.
True HDR does have a considerable improvement in picture quality. In the TV picture quality, the current resolution, color gamut, gray scale, frame rate and other issues have been improved with the advancement of technology, but the current television content still uses the SDR standard, which makes the previous TV always in the brightness dynamic range parameters Maintain a lower level.
The emergence of HDR technology has finally made up for this short board, which enhances TV brightness and contrast in all directions. The increase of brightness makes the picture more plentiful and will not be destroyed by a slightly higher or lower brightness, and the original content of the picture will be presented more completely and truly.
What are the elements that are needed for a true HDR TV? At this time, it is necessary to look not only at whether or not the TV is equipped with HDR technology, but also with an HDR decoder chip. At the same time, it is necessary to pay attention to whether the TV complies with the corresponding HDR standard. The current mainstream HDR technology standards are HDR10 and Dolby Vision, which can be seen when purchasing a TV or browsing online shopping pages.
Dolby Vision is the latest HDR standard developed by Dolby and includes a complete solution. It uses a hardware solution that enhances each frame through frame-by-frame rendering, and supports 12-bit color depth to make the TV more uniform and smooth in color.
In some high-end TVs that Samsung, Sony and LG have introduced, we can often see the HDR10 standard. Among them, the "10" of HDR10 refers to 10Bit, that is, the TV supports 10Bit color depth. But now HDR10 is also starting to upgrade, and HDR10+ is starting to enter the market. Compared with HDR10, which only processes all data in the source, the HDR10+ allows the image quality to be commensurate with the Dolby Vision. At the same time, the higher degree of freedom also makes the HDR10+ an attractive target for television manufacturers.
Therefore, for TV products, even if they are equipped with HDR technology, low-priced products are not really HDR TVs. Consumers with high demand for TV picture quality can purchase TVs based on different HDR standards.
