How deep can you imagine HDR TV water?

**How Deep Is the HDR TV Water?** In the past two years, HDR has taken off in a big way. Whether online or offline, HDR seems to have become a "must-have" feature for TVs. On product pages and in shopping guides, there are countless claims about HDR technology—described as "big flickers" and "word games." At first, it sounded amazing: equipped with this tech, blessed with this function. But when you bring it home, you realize it's not quite what you expected. Senior industry players say: these HDR TVs shouldn’t be bought. In reality, the deepest water in the current TV market is probably the "HDR" technology. Open up e-commerce sites like Tmall, JD.com, or Suning and search for "HDR TV"—the cheapest one with the title of "HDR 4K TV" costs just 1,498 yuan; mainstream models are around 5,000 yuan, while some high-end HDR TVs can cost tens of thousands or even hundreds of thousands. Searching for HDR TVs on e-commerce platforms shows huge price differences. Before the big brands caught on, almost all TVs already supported HDR technology. This led to an awkward situation: the signature product in stores became HDR TVs, but few people truly understood what HDR was. The same is an HDR TV, yet the prices vary widely. How do you tell the difference between a real and fake HDR TV? What benefits does HDR technology actually bring? Over the past few days, I went shopping and gathered information, and found that many people still got tricked by "fake" HDR TVs. This image is from a friend. He originally bought a 4K TV, hoping to enjoy the HDR picture enhancement from Xbox games, only to find out the TV didn't support it at all! So, just because a TV claims to have HDR technology on an e-commerce site doesn't mean you can freely experience HDR optimization. In fact, things are far more complicated than they seem. Do you know what HDR is? Did you know there are currently three different technical formats for HDR? Did you know that gaming should correspond to HDR10, while watching Blu-ray movies should match Dolby Vision? If you're not clear on these, read this article carefully—otherwise, you might end up being taken advantage of by sellers. Avoiding Big Flickers: Understanding HDR Technology First, we need to understand what HDR is. Long technical explanations are everywhere online, but when buying a TV, no one has the patience to dive deep. Today, we'll summarize the benefits of HDR technology in one sentence: TVs with this technology can enhance the dark areas, reduce glare in bright parts, and make colors more vivid. As shown in the image on the right, the black is deeper, details are preserved, highlights are brighter, and colors are richer. The ultimate goal of HDR technology is to make the image on your TV closer to reality. To put it simply, it’s about letting you see a picture that looks more like the real world on your TV—of course, all display technologies are working toward this goal. HDR is an emerging technology, and there is currently no clear industry standard. However, TV HDR is still in its early stages, and the entire industry hasn't reached a consensus on standards, technologies, or even concepts. Therefore, most 4K TVs now claim to support HDR. Manufacturers are pushing it hard, fearing that without it, their products won't sell. After all, there's no regulation in place. TV HDR technology is chaotic due to the lack of unified industry standards. As everyone knows, HDR TVs on the market support different HDR standards. If you’re not careful, you could end up in an embarrassing situation like this: you bought an Xbox One console, only to find out your TV doesn’t support HDR10 games. So, understanding which HDR format a TV supports is the first step in choosing the right one. Before buying an HDR TV, you should understand these HDR standards. The birth of any new technology is often accompanied by a battle over standards. Like the full-screen phones in the mobile phone industry—if no association or institution defines what a full screen is, anyone can claim their phone is a full-screen model. However, the concept of full screen is easy to judge with the naked eye, unlike HDR, which is much more complex. Before being clearly informed, average consumers can't easily tell what kind of HDR technology a TV uses, or whether it's even equipped with HDR. Who knows what hidden tricks are behind that screen? Two common HDR video formats. Therefore, in order to determine whether a TV's image restoration capabilities meet the corresponding HDR standards, different organizations have developed various HDR standards. You may have seen some TVs or monitors claiming to support HDR10. In fact, HDR10 is one of the HDR standards. HDR10, Dolby Vision, and HLG are the three major HDR standards today. Most people are familiar with HDR10 and Dolby Vision, while fewer may have heard of HLG. Let’s start with HLG. - **HLG Standard** The HLG standard was originally developed jointly by the British BBC and the Japanese NHK. Its most fundamental feature is that a single signal stream can be compatible with both HDR and non-HDR TVs. The benefits of HLG are obvious: since it's compatible with regular TVs, broadcasters and content creators don't need to deploy two different transmission systems, saving time and money. Additionally, because HLG is supported by the Japan Broadcasting Industry and Business Association (ARIB), it can be used without a license fee. This makes it likely to be popularized in the broadcast TV industry. From this perspective, we don’t need to worry too much about whether our purchased HDR TV supports the HLG standard. It's still a distant issue until TV broadcasts adopt HDR signals. - **HDR10 and Dolby Vision** Next, let’s talk about the two more mainstream HDR standards: HDR10 and Dolby Vision. To describe the relationship between them in one sentence: HDR10 is more like the "low version" of Dolby Vision. First, Dolby Vision uses 12-bit color, while HDR10 uses 10-bit color. From the perspective of color gamut, Dolby Vision is better. Samsung has also upgraded to HDR10+, but it remains free. Furthermore, since HDR10 is a compromise made by standard makers to meet the average performance of most devices, it is free. To get Dolby Vision with a better display effect, TV manufacturers need to pay Dolby a patent fee, and this cost will eventually be passed on to consumers. In other words, HDR10 has broader compatibility and is "big, complete, and free"; Dolby Vision is "smaller, finer, and paid." As for how to choose, it's up to the individual. How do I choose between the three HDR standards? What HDR format do I need for gaming and watching movies, and how do I choose? We know the three HDR standards, but can we choose the right TV if we have the right number of seats? Not really! If you're a gamer, you should know that the current PS4 Pro and Xbox One X game consoles only support the HDR10 standard. If you're a Blu-ray movie fan, you must understand that 4K UHD Blu-ray discs already support the widely used HDR10 format, and a small part supports Dolby Vision. This depends not only on which HDR standard your TV supports, but also on whether the Blu-ray source supports the corresponding HDR standard. I thought I had already learned about the three HDR standards and understood my needs, so I could happily choose my favorite HDR TV. However, on the product description pages of e-commerce sites, you can't find any information about which HDR standard the TV supports. Many TV manufacturers just say "supports HDR" and mention that the picture quality is more realistic and the effect is more amazing. But there's no mention of which HDR standard they support. That's why I said earlier that the depth of HDR technology in TVs isn't unreasonable. Some brand TV product introduction pages only say "support HDR" and don't explain the standard. For example, the above "desirable" description method means that when you choose an HDR TV from such brands, you must be cautious and ask questions. Consult customer service to find out which HDR standard the TV supports. If the seller is vague and evasive, then this product is not reliable. Some joint-venture TV manufacturers will clearly state the HDR standard supported by the product and avoid misleading consumers. Fortunately, there are still some "conscience" TV brands that specifically indicate which HDR standard their TVs support and don't play with customers. Currently, Samsung, Sony, Hisense, Sharp, and Philips clearly state that their HDR TVs support the HDR10 standard. Meanwhile, LG supports both HDR10 and Dolby Vision. "Fake" HDR TVs don't support PS4 Pro. Therefore, it's more reliable to choose HDR TVs from the above brands that support the corresponding standards. For low-cost brands that only say "support HDR" without mentioning the format, you should be more careful when purchasing. It might have a built-in "filter" effect, but it falsely claims to be a genuine HDR TV that meets industry standards. Plug in the PS4 Pro and find out that the HDR effect can't be activated at all—you’ll just have to cry silently under the bed. If you don't want to think too much, here's the easiest way: take the Xbox One X or PS4 Pro to the physical store, connect it to the TV, and try to see if it's compatible with 4K HDR. Don't rely on shopping guides. Cheap HDR TVs are just a pseudo-proposition. I can tell you honestly: cheap HDR TVs simply don't exist! Regarding the current chaos and pricing issues in the HDR TV market, I’d like to say a few things: First, I don’t recommend buying "low-end" HDR TVs in the 1000–2000 yuan range. These TVs may only have minimal effort in the decoding chip, supporting basic playback, but the picture enhancement is minimal, and sometimes even counterproductive. Worse still, they may not support the HDR10 standard at all, making them a real "fake HDR" TV. Cheap HDR TVs simply don't exist.
