Sony's top-of-the-line TV Z9D is currently the best 4K HDR TV

To be honest, the appearance of the Z9D is not a publicity. If it is not specifically stated, people who see it at first glance may not feel that it is a super flagship product that is positioned much higher than an ordinary TV. Because it doesn't have the elegance of curved lines on curved TVs, or the super-thin thickness of OLED TVs. Regardless of the width of the frame, the thickness of the screen, or even the style of the base, the Z9D can be said to be very simple, and there is no such feeling that people will feel suddenly bright. Said a real thing, a few days ago I went to the appliance store, into the Sony counter, after 30 seconds simply did not find which is the Z9D!

Minimalist & low-key industrial design

However, this does not mean that the Z9D is a product that does not pay much attention to design but only sells high prices based on image quality and sentiment.

Under the low-key and extremely simple appearance of the Z9D, it is the pursuit of various materials and processing techniques. For example, in its border part, in addition to using more textured metal, it also uses a golden color scheme that Sony rarely uses on television sets, revealing a hint of luxury in the main colors of dark gray. As for the appearance of the Z9D, what kind of process, what kind of material, and how many processes are used to create them, according to Sony's consistent style is not to be advocated to the outside world (if it is replaced with an Internet brand, most consumers will Has been brainwashed by various new terms, so we only need to feel through sight and touch. A good product can speak for itself.

At the same time, we can also find some very classic, Sony BRAVIA family elements under the minimalist look of the Z9D. For example, breathing lights that have never changed, suspensive pedestals, and even some old-fashioned multi-key remotes... all of these allow Sony’s old users to find the familiar feeling in the first place. Users also have the opportunity to experience the heritage of Sony's industrial design.

Black technology must mention: BacklightMaster Drive

Although the word “black technology” has recently been overused, after thinking about it, it still feels that only using the term “black technology” can most accurately express my understanding of it.

First of all, the biggest breakthrough in the hardware part of the Z9D is the transformation of the LCD's key backlight structure: the new "Backlight Master Drive". The strength of this backlight is: 1, the use of ultra-high density direct matrix LED backlight (although in the end how many LED particles Sony does not explain, but from its performance will never be a small number, behind (There will be evidence); 2, it can achieve independent brightness and brightness control for each LED particle, and is based on real-time video signal control; 3, in order to prevent the light interference between the LED particles, specifically designed a The bundled structure allows each LED's light to shine only in the corresponding area.

Recalling the history of the development of LCD TVs, there have been products that have adopted direct-lit LED backlights, all of which have become a classic. However, in the traditional direct-type LED layout, in addition to the small number of LED particles, and due to the limitations of the backlight drive technology, the so-called dynamic backlight control can only be divided into a number of small areas in accordance with a certain area of ​​the backlight control, ranging from a few, if It is already possible to achieve dozens or even hundreds of districts, and the Z9D can do it. In the past, no opponent has ever appeared.

I had seen the power of Dynamic Backlight System - Master Edition at CES this year: At that time, Sony placed two master LCDs with dynamic backlight system side by side, but one of them removed the liquid crystal layer, leaving only the backlight system. In this way, people can intuitively see the working status of the backlight when the television is displaying various screens. The effect is indeed very shocking, because it looks like watching a black and white TV screen with a slightly lower resolution, and the accuracy of its backlight is evident. And another advantage of this high-density LED layout is that it allows brighter parts of the image to achieve higher brightness, which is why the Z9D's HDR performance far exceeds the average HDR TV.

In addition to the extremely precise and subtle control of the backlight area, this new backlighting system also allows the Z9D to have a brighter and lighter brightness reproduction range that surpasses that of ordinary HDR televisions. In fact, at the time of demonstrating the "BacklightMaster Drive" technology prototype at CES, Sony said that it was already possible to achieve screen brightness of up to 4,000 nits (although the highest-end HDR TV on the market is currently available.) 1000 nits peak brightness already belongs to high-performance models). Although Sony has not yet announced the Z9D's highest brightness index, it is certainly beyond the mainstream HDR TV. The Z9D has a display capability that is closer to the real-world brightness range at the physical level, which is also hard to reach for so-called HDR TVs that only process HDR signals.

Three new feature-capable X1 Extreme chips

Another comparison of the Z9D has been neglected, but the technology that plays a role in no less than the importance of the backlight system is the integration of the three new technologies of “HDR dynamic item-by-item remodeling technology, dual image database, and SuperBitMapping 4K HDR”. "4K HDR image processing engine".

First of all, let's talk about the real thing of this image engine in the physical layer, which is the X1 Extreme chip. Unlike other color TV manufacturers' X-core CPUs and nuclear GPUs, the X1 Extreme is a chip that is completely used for image quality processing, and has nothing to do with those running points. This chip is entirely owned by Sony itself and is neither sold nor authorized. We only know that its computing power is 1.4 times that of current X1 chips used in high-end machines.

X1 Extreme's computing power is not used to run points. It is entirely for processing images. Therefore, it can achieve frame-by-frame processing of 4K resolution video signals.

The first new technology: "HDR dynamic item-by-item reshaping technology" can detect and analyze each object in the frame frame by frame and give the best optimization algorithm. After optimizing the details in each frame of the image, the image engine performs HDR shading adjustment according to the overall contrast of the frame. After two rounds of optimized remodeling, the image shows not only the light and darkness of the detail part is more true, but also can show more excellent light and shadow effects and contrast of light and shade, gradual change of light intensity and even halo performance at the overall macro level. It is difficult to achieve on ordinary HDR TV.

The second new technology "Dual Image Database" is one of the souls of Sony's image processing technology and is mainly used for noise reduction. Compared with Sony's past noise reduction technology, this technology can realize the recognition of different elements in the image such as foreground and background, and compares and reduces noise through a huge image database. In fact, on the Z9D launch event, many people have seen the difference between the noise reduction effects of the ZQD and the mainstream QD TVs and OLED TVs on the market. The effect even exceeds the OLED TVs known for their darkness. The reason is that OLED TVs are In the absence of high-performance noise reduction processing technology, it is easy to display noise as a video signal, which affects the performance of the dark part.

The third new technology is a 4K HDR 14-bit smooth gradient. Many people have had the experience of seeing a noticeable color gamut on the screen of a television screen. The main reason is not that the color expression of the screen is not enough, but the lack of color management capabilities behind it. The 4K HDR 14-bit Smooth Gradient Technology analyzes the image frame by frame and performs 14-bit smoothing of the image to fully optimize the gradation and achieve a lower gradation, which means a more natural color transition.

The five factors that affect image quality are: spatial resolution, temporal resolution, color gamut, brightness range, and grayscale range. To evaluate Z9D from these five dimensions, it not only has a balanced overall performance, but also has a high standard for each single item. Do not want to use too much vocabulary to praise the Z9D. I just want to suggest that AV lovers and HD enthusiasts have the opportunity to go to the store to see the true picture effect of the Z9D, because this TV can tell you that the highest level in the industry is now What is the picture quality?

The Z9D has an impressive and memorable color expression. This is an exaggerated and contrived color style. It looks both pleasing and real. The Z9D can also accurately reproduce any subtle changes in color and light and shade, and can even respond to challenging scenes with great brightness contrast like active display devices. It is hard to imagine that it is essentially a Passive light-emitting LCD TV. The Z9D also retains Sony's quintessence in color tuning. It not only provides ordinary users with a wide range of professional-grade image mode choices, but also provides professional users with a high degree of freedom for personal tuning in the later stages. The overall performance is nearly perfect.

The new Android system intelligence is no longer a short board

Compared with various "black technologies" on the picture quality, although the performance of the Z9D in smart features has not been significantly ahead of this era, experience still feels like the best system Sony has ever used. The Z9D uses Andriod TV6.0 platform which is specially adapted for large screens by Android, but it retains some features and habits of Sony since the XMB system in terms of UI style including manipulation, whether it is fluency or ease of use. In addition, compared to Samsung’s Tizen system and LG’s WebOS system, Android’s richness and extensibility performance will be even better. Z9D’s choice is also wise.

The number of APPs provided by the Z9D is not limited, and there are also some Sony-specific APPs, such as the Hi-res HD music app. In addition, due to the Android system, users can also install a variety of common third-party TV apps in the app store.

In terms of control, the Z9D's remote control is very traditional, but it also provides such a convenient function as voice search. In addition, the user can try to increase the linkage of the PS4 controller and project the screen of the mobile phone through the APP, which is equivalent to the performance of mainstream smart TVs in the market. On the video-on-demand service that many people are concerned about, the Z9D still uses the Wahiti TV broadcast control platform, but Sony does not have a random gift. If users want to watch the latest videos, they must pay for their own subscriptions. However, the Z9D uses the Android platform. Users can also implement video on demand through third-party video applications.

Summary: The best 4K HDR TV

The appearance of the low-key Z9D is absolutely the most advanced image quality performance. The Sony Z9D has reached a level that is difficult to reach in general LCD TVs in every aspect of the quality of the picture, such as brightness reproduction range, smoothness of color gradation, detail definition of 4K images, and color expressiveness. Even with dark display effects, even noise reduction circuits and powerful backlighting systems have not lost the performance of OLED TVs with inherent advantages. After reading the Z9D's picture, the personal feeling is that the picture is very comfortable and balanced. Second, the picture has a sense of reality that is hard to describe in words. This feeling has never been experienced in other TVs.

Finally want to talk about the price of Z9D. When the listing price of Z9D was announced, someone spoke to be expensive. Indeed, the prices of 65吋32999, 75吋43,999 yuan are really too much more than those of the Internet brands 65-inch and 70-plus TVs that are just a few thousand pieces. And the appearance of the Z9D doesn't look cool at all. Here I just want to say that 1, the price of domestic Z9D is actually very kind, do not believe you look up its offer in the United States, on average more than 10,000 more expensive than domestic. 2, this price, absolutely worthy of its performance. In the end, I strongly recommend that you have a chance to visit the Z9D's real picture in the store. This TV can tell you what the highest level of quality in the industry is!
