Sony 65 inch Z9D Review: LCD quality can be better

Nowadays, competition in the color TV industry is fierce. The influx of internet companies has filled the lake with a slightly calmer atmosphere. At the same time, with the passage of time and the popularity of TV boxes, the differentiation between content resources and intelligent interactions has become smaller and smaller, and the competition of television has gradually returned to the quality and appearance. HDR, Quantum Dots, and OLEDs, with ever-changing technological changes, large screens, curved surfaces, and integrated, industrial design innovations.

But if you have a flagship TV that does not use technology-rich OLED technology, or choose impactful surface design, it still continues its flat-screen TV has always been low-key and simple style, you may think it can not be called the flagship, It is not even enough to keep up with the times.

However, this is also a series of products that have always been advertised by consumers as "black technology," and often people shout and recharge their faith. Yes, you may have guessed that what we have to say this time is Sony Dafa’s latest 4K HDR flagship TV Z9D series, equipped with Sony’s new image processing chip and technology, claiming to be the king of the current TV picture quality. What is the quality of this 30,000-plus TV product? Tencent home appliances will be followed by everyone to experience it.

Low-key and steady integrated design


Sony Z9D has 65-inch, 75-inch, 100-inch three specifications, and we get a price of 32999 yuan 65-inch version of the 65Z9D. It can be seen that the overall design of the 65Z9D continues to be consistent with the deep tone of the Sony-based products. The large-area black is used, with the visual effect of a narrow frame, which is very stable and generous.


The embellishment of Sony's classic breathing light at the bottom of the screen adds a touch of technology. The double sided metal edging on the sides, although not much in terms of thickness, does not affect the exquisite feel, and the workmanship is still very good.

On the base, Sony Z9D did not use a popular pair of herringbone brackets, or a simple flat bottom base; instead, it was designed to be a two-piece structure that formed an arched structure. According to reports, in addition to being more of a design sense, it can also play a role in reflecting the sound field.

The backplane part also adhered to the minimalist integration concept. The hidden design of the wire was basically handled in the removable backplane and hidden in the bracket part.

In general, minimalist, integrated design styles have become the current trend, but as far as Sony is concerned, it has always been such a low-key and steady design, but it has never lacked cutting-edge technology. sense.

Android system expansion space

In the system selection, Sony 65Z9D uses Android TV, after the adaptation of the main page is very simple and refreshing. At the same time, compared to Tizen and webOS systems, Android TV has better compatibility and richer applications.


In the secondary menu, if you set up the system, you will find that it is very "face-to-face". Both the picture and sound effects are very close to the Play Station's style. It also covers settings such as common channel settings, external input, display settings, Bluetooth, and external devices.

In the actual operation process, the system is also very smooth; standard remote control is also good in handling feeling and key process feedback. However, due to the large number of keys, it is not very easy to get started and it takes a while to become familiar.

In terms of content, the license partner selected by Sony is Huadian TV. It can be seen that the adaptation of the application interface of Huashi TV cannot reach the exquisite degree of the main interface and needs further optimization. In terms of video resources, most of the sources in Sony TV are mainly popular or classic movies such as “Crazy Animal City” and “Star Wars Force Awakening”. Moreover, due to the Android system, users are also free to install third-party video software.

In terms of applications, because it is based on the Android system, it is still very rich, covering several major sections of entertainment, applications, games, and management. It basically includes the current mainstream Android games, and the interface is also well-adapted.

Clear color reproduction

In addition to excellent industrial design, excellent image quality has always been the advantage of Sony TV. The newly released Z9D series is equipped with a brand-new backlight technology and image processing chip: Backlight Master Driver and 4K X1 EXTREME image processing chip, while the brightness is also farther than 1000nit HDR TV on the supermarket. . Next we take a look at its actual performance.

First of all, we conducted the conventional 4K TV test and selected several classic test charts: 4K TV resolution test chart, 4K TV tone level restoration test chart, 4K TV color performance and visual angle test chart.


In the resolution test chart, 65Z9D can accurately identify the text pointed by the red arrow in the picture. At the same time, the boundary of the line and the detail of the color block are also relatively clear, indicating that the television has achieved 4K resolution.

In the 4K TV screen level restoration test chart, the 21st-level gray scale of the spherical map can be basically resolved, the transition is relatively smooth, no obvious jump-level phenomenon occurs, and it reaches a very good level.

In the test of color performance and viewing angle, the triangle in the color distribution diagram can be seen more clearly, and the reduction power is strong; the sphere in the color ball diagram is also rich in layers and the transition is soft.

Control light precise and detailed

In actual use, how can Z9D watch videos and pictures? For example, in the colorful landscape with complex levels of detail, we can see that the Z9D is very natural in terms of the level of clouds in the sky and the red color transition. At the same time, the detail of the tent on the ground is also very clear. .



In the dark field test section, it can be seen that in the case of a limited single light source, the Z9D has precise control over the dark field, and the black color is relatively pure; meanwhile, when dealing with the color at the light source and the details of the middle edge of the stage, Richer sense of hierarchy. The audience in the dark, are also more clearly presented.

The performance of these screens mainly stems from the Z9D's use of the new Dynamic Backlight System Master Edition, which changes the layout of side-entry backlights that are common on LCD TVs and uses a high-density direct-to-back matrix backlight to achieve the picture. The precise control of the brightness, the number of backlight partitions exceeds 1000 (the specific number of Sony is not announced). Sony also significantly reduced light scattering on conventional full-matrix LED TVs by concentrating scattered LED light to one point, resulting in higher color contrast and a wider color gamut.

Then in the actual face restoration test section, we selected the HD specification source, and we can clearly see that the Z9D is more natural in terms of human face characterization. At the same time, the details of the signboards and texts in the distant buildings can also be better restored.

It is reported that this is because the Z9D is equipped with a 4K HDR image processing chip X1 Extreme, which can improve the quality of the SDR standard dynamic range content of the HD specification to a level close to that of a native 4K HDR, which is mainly due to its accumulation in upstream shooting and post-production. Professional experience, as well as decades of professional TV manufacturing experience. It can use Sony's accumulated image database to perform noise reduction processing. Through pattern comparison, double database processing technology is used to remove unnecessary noise in each frame of the image, and finally achieve 4K level definition.


Also because of the use of new processors, the Z9D can handle dynamic video better. The high-speed scrolling map is displayed on the screen. We can see that the Z9D does not appear trailing, ghosting or even Caton.

In the HDR comprehensive test, we can clearly see the performance of the Z9D. Its neon color reproduction, brightness control, and halo processing are very natural and outstanding. At the same time, the details in the dark can be well presented. The part is also very dark and the overall picture is very natural.

This is also because the Z9D uses a new backlight technology and processing chip to obtain a higher color contrast and a wider range of color gamut, so that its HDR technology can also be better played, and thus has a more excellent image quality performance .

summary

With the rapid development of science and technology, the upgrading of consumer electronics products is accelerating, and television products that are biased towards traditional fields have not been the exception. More and more high-end smart TVs are being deployed, and large-size TVs with ever-lower prices have emerged in an endless stream, stirring up the entire color TV industry and also causing a greater impact on traditional TV manufacturers. But perhaps because of this, we see the speed of new technologies being introduced on the market getting faster and faster, especially with respect to the improvement of picture quality. After all, a TV is still used to see, and the quality is always its fundamental and fundamental, so whether it is a more radical innovation or a more in-depth study, it is worthy of recognition.


In general, the Sony Z9D continues its low-key and stable black style in appearance, paying more attention to the integrated minimalist design and exquisite workmanship. At the same time, the Android ZTV is also more extensible on the system. The interaction logic is very clear. , smooth experience; and some details need to be optimized, such as third-party applications slightly rough UI design, and the overall style will not match, while favoring the traditional remote control keys are more, the control is a certain need Time to adapt.

In addition to industrial design, image quality has always been the focus of Sony, and in the newly released Z9D this flat-panel LCD TV has brought new technology upgrades. The actual performance of the picture quality is indeed better than that of ordinary TV. For example, the color and level of the picture can be restored very well. The color of the character can also be expressed naturally. At the same time, it is also more accurate in controlling light. The details of the shade can be well presented. So although its price of 32,999 yuan is more expensive than domestically produced TVs, it is still worthwhile considering its overall performance in terms of quality, industrial design, workmanship, and interactive experience.
