How deep is the HDR TV water, you may not be able to imagine
In the past two years, HDR has been fired and the fire is incredible. Regardless of whether it is online or offline, HDR seems to have become the "must-have attribute" of TV. The introduction of the product page and the "big flicker" and word games about HDR technology are all overwhelming. Well said at the time: carrying this technology, bless this function; but we bought it home and found that it is not the case.
Senior players tell you: these HDR TVs can't be bought.
In fact, as far as the current TV market is concerned, the deepest water is probably the "HDR" technology. Let's open the e-commerce pages of Tmall, Jingdong and Suning, and search for "HDR TV" - the cheapest, with HDR title. "The 4K TV, as long as 1498 yuan; and the mainstream price is concentrated at 5,000 yuan; some high-end HDR TV prices have reached tens of thousands or even hundreds of thousands.
Searching for HDR TV in e-commerce: the price is quite different
Almost all TVs already support HDR technology before the big guys have figured it out. This caused a very embarrassing phenomenon: the signature goods in the store became a HDR TV, but few people knew about HDR technology. The same is HDR TV, the price is different, how should we distinguish the "true and false" HDR TV? What benefits can HDR technology bring to me?
These days, I went to the post to collect the materials and found that many people were still pitted by the "fake" HDR TV.
Originally wanted to buy an HDR TV to play Xbox, and found that HDR10 games are not supported at all.
The above is a picture of a friend's sun. I originally bought a 4K TV. I wanted to experience the HDR image enhancement brought by the Xbox game. I found that the TV didn't support it at all! So, it's not that you searched for a TV that claims to be equipped with HDR technology, and you can experience HDR optimization "on the go".
In fact, the things inside are far more complicated than you think. Do you know what HDR is? Do you know that HDR currently has three technical formats? Do you know that playing games should correspond to HDR10, and do Blu-ray movies correspond to Dolby World? If you are not sure about this, please read this article carefully. Otherwise, you can only slash the squid and let the merchant slaughter.
Avoid big flicker: HDR technology starts
First of all, we have to know what is HDR?
Long technical analysis, a lot on the network, buy a TV, and no one has the patience to study so deeply. Today we will use a sentence to summarize the benefits of HDR technology: TVs with this technology can be like the picture below, the left side of the original dark part of the dark, bright and dazzling, less colorful pictures, "tune" The picture on the right is darker and the details are not lost, the brighter parts are brighter and the colors are more abundant.
The ultimate goal of HDR technology is to make the picture we see on TV closer to the real world.
To put it bluntly, it is to let you see a picture closer to the real world in front of the TV - of course, all current display technologies are working around this goal.
HDR is an emerging technology, and there is currently no clear industry standard.
However, TV HDR is completely an emerging technology, and the whole industry is still in its infancy. Relevant standards, technologies and even concepts have not yet been unified, and it can be described as chaotic. Therefore, the market is basically a 4K TV, and they all dare to say that they are equipped with HDR technology. Manufacturers have spared no effort to promote HDR. If they are afraid of it, the products will not be sold. Anyway, no one will control it.
TV HDR technology is not a unified industry standard, so it is a mess
As everyone knows, the HDR standard supported by HDR TVs on the market is not the same. A little careless, the above mentioned: I bought the Xbox One console, but found that the TV does not support the HDR10 game at all. Therefore, screening the different standard HDR formats is the first step for HDMI TVs for the average consumer.
Before buying HDR TV, you should know about these HDR standards.
The birth of any new technology is accompanied by a standard battle, just like the full screen of the current mobile phone industry being smashed – if no association or institution stands up to define a comprehensive screen, then anyone can claim to do it. It is the "real" full-screen phone. Of course, the comprehensive screen is not related to the concept of the upstream and downstream industry chain, so the development of relevant standards is also less urgent.
However, the standard of the full screen can be discerned by the naked eye; but HDR is much more complicated, and it is impossible for ordinary consumers to know clearly before they are explicitly told: Which HDR technology is used in a TV? Equipped with HDR technology - the ghost knows which tricks are hidden behind the screen?
Two common HDR video formats
Therefore, in order to define whether the image restoration capabilities of TV manufacturers really meet the corresponding HDR standards, different organizations have developed different HDR standards. You may have seen some TVs or monitors claiming to support HDR10. In fact, HDR10 here is one of the HDR standards.
HDR10, Dolby Vision, HLG are the current three major HDR standards
Regarding the current three mainstream HDR standards, everyone should be familiar with HDR10 and Dolby Vision, and for HLG, there may be fewer people who have heard of it. Then let's introduce HLG first.
-HLG standard
In fact, the HLG standard was originally developed jointly by the British BBC and NHK TV. Its most fundamental feature is that the individual signal streams broadcast can be compatible with both HDR and non-HDR TVs. Therefore, the benefits of HLG are very obvious: because it is compatible with ordinary TV, TV stations and content creators do not need to deploy two different signal delivery systems, which saves everyone's time and money.
HLG standard
In addition, because HLG has the support from the Japan Broadcasting Industry and Business Association (ARIB), it can be used without an authorization fee, so this standard is likely to become popular in the broadcast and television industry. From this point of view, we do not need to worry about whether the purchased HDR TV supports the HLG standard. After all, it is still a distant matter to wait until the TV broadcast popularizes the HDR signal source.
-HDR10 and Dolby Vision
Next, let's talk about the two mainstream HDR standards - HDR 10 and Dolby Vision. In one sentence, the relationship between the two is described, that is, HDR 10 is more like the "low version" of Dolby Vision. First, Dolby Vision uses 12-bit color, while HDR 10 uses 10-bit color. From a color gamut perspective, Dolby Vision is better.
Samsung has upgraded HDR 10+ standard upgrade is not small but still free
Furthermore, since HDR 10 is a "compromise product" that standard setters make to meet the average performance of most devices, it is free. And to get better display of Dolby Vision, TV manufacturers need to pay Dolby a royalty, and this part of the cost is bound to be passed on to consumers. In other words, HDR 10 compatibility is better "big and full and free"; Dolby Vision is "small but fine but chargeable". As for how to choose, the benevolent sees the wise and sees wisdom.
How do I choose three HDR standards?
What HDR format do you need to play games and watch movies? How do I choose?
We know the three HDR standards. Can you choose the right TV for the right one? Not also!
If you are a gamer, you should know that the current PS4 PRO and XBOX One X game consoles only support the HDR 10 standard;
If you're a Blu-ray movie fan, you have to understand that the current 4K UHD Blu-ray Disc already provides support for the widely used HDR 10 format, and a small portion supports Dolby Vision. This depends not only on which HDR standard the TV is compatible with, but also whether the Blu-ray source supports the corresponding HDR standard.
Originally thought to have been immersed in three HDR standards, and already understand their needs for a certain standard, you can be happy to choose your favorite HDR TV. However, in the e-commerce product introduction page, we can't find a description of which HDR standard is supported by a certain TV! Regarding the HDR item, quite a few TV manufacturers just took the opportunity to say that they "support HDR", and what "this picture quality is more real, that effect is more amazing." However, there is no mention of which HDR technology standard is supported, so I am not afraid to say that the depth of TV HDR technology is open.
Some brand TV product introduction pages only say "support HDR".
For example, like the above-mentioned "intentional speculation" description, we must keep our eyes on the HDR TV such as this kind of brand, and ask the customer to find out what HDR standard this TV supports. If the opposite side is ambiguous, and he is concerned about it, then this product does not buy.
Some joint venture TV manufacturers will clearly mark the HDR standard supported by the product, and do not steal the concept.
Fortunately, there are still some TV brands that are more "conscience", which will specifically indicate which standard HDR supported by their TV products belongs to, and do not circle with consumers. At present, it is clear that Samsung, Sony, Hisense, Sharp, Philips and other brands have demonstrated that their HDR TV supports the HDR 10 standard; while LG Electronics supports both HDR 10 and Dolby Vision standards.
"False" HDR TV does not support PS4 PRO
Therefore, it is more reliable to choose the corresponding standard HDR TV from the above brands. For some TV brands that are "low-priced" and "only support HDR, but don't mention which format", I can only say that I have more to keep in mind when I buy. Maybe it's a fake HDR TV that includes a built-in "filter" effect, but forcing it to meet industry standards - plugging in the PS4 PRO and discovering that it can't open the HDR effect, it can only cry in silence.
If you don't want to think so much, there is one way to be the easiest: go directly to the offline store with XBOX ONE X or PS4 PRO, and then try to see if 4K HDR is compatible with the TV. The guide is no use.
Cheap HDR TV is simply a pseudo-proposition
I can tell you responsibly: cheap HDR TV does not exist at all!
For the current chaos and price issues in the HDR TV market, I have a few words to say:
First of all, I don't recommend you to buy the "low-end" HDR TVs in the 1000-2000 price range, because they only work on the decoder chip, and can only support the playback of the film source, but the improvement of the picture effect can be said. It is very small and even counterproductive. Even more, the HDR 10 standard is not supported at all, which is a true "false HDR" TV.
