Now with the increasingly serious homogenization, the TV industry has begun a new round of shuffling. In the past, the market pattern oriented by product price competition has begun to change towards quality and high-end. The previous competition led by price war has also returned to the road of taking user experience as the core and creating higher added value for users. Among them, some high-end brand TV products always focus on the high-end market with absolute technical advantages, and are committed to bringing more extreme audio-visual experience to those users who pursue quality life. Sony TV's Huadi series TV is the best proof.

Appearance design : Unbounded full screen brings big vision

The TV adopts minimalist design as a whole. The screen is wrapped in a single piece of glass to create a comprehensive screen without seams. The high screen proportion further highlights the screen and highlights the unique immersion brought by the large screen. At the same time, the narrow frame also allows the audience to focus on the screen without frame interference.

Sony has always attached great importance to the industrial design of products. Compared with the previous generation of products, the a90j optimized the design of the fuselage, and at the same time, it was more careful in the selection of details and materials. A detachable baffle is still provided on the back of the TV to cover the exposed data cable, which can realize the elegant back cable layout, so that users can still maintain excellent back integrity when connecting a variety of devices. This excellent cable management ability has obvious advantages over other TV products.

After installing the backplane, the redundant plugs and cables are well hidden

The previous generation a9g used a rounded rectangular metal bracket to support the whole TV, making the bottom frame very close to the desktop, only 6mm away, almost integrated with the desktop. The a90j follows the design of this visually hidden base and improves its function. The a90j uses a two-way bracket, which has two holes. Different bracket options can be provided during installation. When the bracket is placed on the outermost side, it can reduce the interference to the vision. At the same time, in order to facilitate users to match echo wall and soundbar and other equipment, the bracket adduction can be improved.

In general, Sony's a90j TV series is outstanding in texture and design. It has both temperament and talent. It adopts unbounded full screen design, standard display mode, simple design style and exquisite production technology to create a narrow frame, which makes this product full of texture.

Image quality experience: XR cognitive chip brings top image quality

Sony picturesque series has always been famous for its excellent audio-visual experience. This Sony picturesque a90j TV is equipped with the XR cognitive chip, which can imitate the way of human vision and hearing to process and optimize the TV content. On the basis of the previous X1 chip, it provides more intelligent picture optimization and presentation.

In the 4K resolution test picture, the whole picture is very clear, even the small words in the upper left corner can clearly display the small words in 4K resolution.

OLED screen with XR cognitive chip , It can cross analyze and optimize thousands of picture elements in a short time , Make the dark scene more profound , The highlight scene is more transparent. XR OLED contrast enhancement Pro technology can make the bright part and dark part of OLED TV picture present together , Let the whole picture keep rich light and dark details at the same time. Xrtm Pro has a wide range of color gamut , Restore more accurate color, tone and texture details of the subtle color changes. Sony's exclusive technology improves the contrast of the picture and the color gamut and dynamic range of RGB , And then control to eliminate color distortion and reduce screen burning.

Through the above tests, it is not difficult to see that a90j, as a new generation of Sony's picturesque TV series, really has a strong strength in display. How about its actual performance? Let's experience it through some film sources.

Thanks to Sony's XR 4K line doubling technology, the a90j can use Sony's accumulated image data over the years to optimize the texture and details of the picture. It can be seen that although some details in the above figure are complicated, they can still be presented in a low noise and high-definition state.

In the dark environment, the a90j can completely show the light transition of the character's face. Although part of the color of the character's face is hidden under the night, the other half shows delicate skin color, which is almost consistent with the effect seen by our human eyes. This flatters the eye color and natural soft texture, so that the a90j does not have the stiffness of some products after optimizing the screen.

[MD:Title]

In the picture with high light to dark ratio, OLED has excellent contrast, which is even better with the help of XR OLED contrast enhancement Pro Technology. When bright field and dark field appear in the picture at the same time, a90j can faithfully restore the details of the image. The flame on the left side is bright, but it is not overexposed under the strong contrast of OLED; the dark wood on the right side can also show the texture after being burned by the flame. The perfect restoration of such pictures also proves the deep foundation of a90j's light control ability.

If the above pictures are not enough to show the excellent pictures of a90j, I believe that we can further experience the sound and picture experience effect of a90j through the high-quality film source.

In the actual experience process, we used the 4K resolution demonstration video, and the entity impression of Sony Huadi series a90j is more delicate. Especially in the scene with rich colors and strong light and shade interlacing, this TV brings users and their excellent visual experience with super contrast. Color has always been a good show for Sony TV. In the process of movie demonstration, the color details of each picture can be perfectly displayed. For users who pursue the ultimate picture experience, the actual impression of this TV is absolutely perfect! According to different contents, different modes can be selected to choose the corresponding mode, For example, when watching a movie, you can choose the color matching to be closer to the texture of the movie.

Now, in order to keep the overall picture more fluent, TV products have added MEMC technology, but some of them are not ideal, especially in the light and shade of the picture. The XR cognitive chip on Sony picturesque a90j can obtain the size and position of the moving object in the image through a large number of cross data analysis, and drive the XR sharp dynamic technology to optimize the dynamic definition. It can also maintain the brightness of the whole picture, minimize the image blur, and make the image still real in the high-speed scene with less brightness loss. Therefore, in the video, the dynamic picture can also maintain a clear and bright image effect.

in addition , Sony Pictures Series OLED TV a90j has two hdmi2 . 1 interface , Support 4K / 120fps input and display , After firmware upgrade in the future , It will also support VRR variable refresh rate, allm automatic low latency mode and other functions , For those who own or will buy the next generation host at home , These features will also greatly enhance the game experience.

Sound quality: immerse in sound field and integrate sound and picture

In addition to the obvious effect of improving the picture, the XR cognitive chip can also analyze the position of the sound in the signal, so that the sound can accurately match the action on the screen. In addition, it can convert ordinary sound up to 5.1.2-channel 3D surround sound, presenting a realistic immersive sound field.

In the actual experience process , We used this TV to show several Hollywood blockbusters , In the movie mission impossible , Whether it's battle scenes or static background music , A90j can perfectly restore the details of the sound , Especially the battle scene , Sword collision , The sound of guns exploding , They are all excellent , It is comparable to the sound experience of home theater.

In addition, in the aspect of playing music, we chose a singer with outstanding human voice like Taylor. The sound sense of live singing is restored in the process of playing. Moreover, the whole sense of space is also created, which has a strong sense of presence. Therefore, whether it's playing blockbusters or listening to songs in daily life, the performance of Huadi a90j is excellent. It can fully meet the requirements of high-end users in terms of sound effects and bring an excellent audio-visual feast.

System and interaction: convenient

At the same time, it can be seen that the a90j also converts different apps into tags on the top of the UI. This design allows users to enter the content directly by adjusting the tags without opening the app. The logic is reasonable.

In terms of Internet content that domestic users are more concerned about, Sony has continued its in-depth cooperation with Tencent this time, with massive and fresh content resources. At the same time, a90j also supports IMAX enhanced, Dolby horizon, Aurora calibration mode and other high-standard movies. Users can watch and find their favorite high-standard video content online directly through the network, so as to further experience the immersion experience brought by a90j's high-quality audio-visual experience.
