[PConline Review] In August of last year, Sony launched an 84-inch 4K TV. I believe everyone still remembers the huge body and the price of up to 170,000 yuan. Although the technology is high-end, 4K TVs can only be the plaything of a few people without the size and price of civilians. In this context, in recent days, many manufacturers have introduced a 45-inch or smaller 4K TV, and as one of the giants in the television industry, Sony has also launched a relatively close to the people's 4K Ultra HD product X9000A. series.

The Sony X9000A series debuted at CES2013. At that time, it attracted a lot of attention. Everyone looked forward to their performance, especially in terms of quality. After all, Sony has confirmed that it is a key development target and put forward a "return to quality. The "origin" of the goal, and 4K has also become Sony's strength. Today, the 55X9000A has already reached the PConline evaluation room first. Let's enjoy the power of this flagship 4K TV.
List of product hardware parameters
Sony X9000A series has 65,55 inch two, resolution of 3840×2160, which is four times the full HD 1080p, uses 4K sharp image processing engine PRO, Terricolor display technology, Motionflow XR 800, magnetic fluid speaker And so on, in addition to intelligent functions, adding a touch of the mirror, smart connections, multi-screen remote control and other functions.
Appearance Appreciation
Sony X9000A uses the design concept of Sense of Quartz. It is similar to the design of the past. The panel is covered by Corning Glass. There is no gap between the screen and the frame. It is very fashionable atmosphere.
The X9000A also uses magnetic fluid technology, which is also the world’s first TV with magnetic fluid speaker design. It includes a soft dome tweeter, a passive radiator that diverges forward and two subwoofers, which can greatly improve playback efficiency. .
The base design is somewhat similar to the W950, both of which are arc-like imitation metallic designs. The biggest difference is in the rear and the support axis. A breathing light was added below the LOGO, and it fits harmoniously.
The back of the fuselage uses a metal backplane. Since the horn is located on the left and right sides, the X9000A appears to be longer than most 16:9 models. The label on the back indicates that the X9000A is manufactured by Shanghai Suoguang Sony.
In terms of interfaces, the X9000A has 4 sets of HDMI, 3 sets of USB, 1 set of LAN, 1 set of color difference, 1 set of optical fibers, and 1 set of PCMCIA interfaces, which is equivalent to most high-end models.
The X9000A is equipped with two remote controllers, one is the common RM-SD017 conventional remote controller, and the other is a newly designed smart remote controller.
The X9000A uses polarized 3D technology. Compared to the shutter type, the X9000A has the advantages of light weight, high 3D image brightness, no flickering, and no need for charging, but it is slightly inferior to the 3D effect.
Quality Data Professional Instrument Testing
First of all, we use the evaluation room professional instrument to carry on the detailed test to the Sony X9000A. In the test, we adjust the X9000A to the standard image mode, and the backlight is adjusted to the brightest. We first record the measured data in the following table.
After professional color analyzer testing, we get X9000A's color saturation equivalent to NTSC color gamut of 91.47%, the average brightness of 127.12cd/m2, ANSI contrast ratio of 2140: 1, is among the top level in LCD products.
Sony KD-55X9000A under the black screen, the light leakage control is very good, almost not aware of the phenomenon of uneven brightness, which is one of the advantages of local light control adjustment.
ANSI contrast refers to dividing the TV picture into 16 blocks of black and white color and testing the center brightness of these blocks separately to obtain more reference picture contrast. Because the dynamic contrast ratio marked by the manufacturer generally refers to the ratio of the full white screen to any point of the full black screen, because many TVs adjust the backlight brightness according to the screen content, so the dynamic contrast reference value is low, and ANSI can reflect TV more realistically. Contrast.
In the macro pixel sequence, Sony's KD-55X9000A's RGB pixels are arranged horizontally. Each sub-pixel is divided into upper and lower two segments. From the pixel point, it can be guessed that it is using AUO's panel.
4K Ultra HD Picture/Video Test
In the 4K ultra high-definition test section, the performance of pictures and videos was tested separately. The first is the picture. The author chose several pictures with a resolution of 3840×2160.
Followed by 4K ultra high-definition video, the author chose a 4K test piece that may be familiar to everyone. It is an MP4 format. The content of the video is rich in color and can better demonstrate the strength of the X9000A.
In the 4K ultra-high-definition test section, the Sony X9000A demonstrated amazing strength, fine-grained graphics, detailed interpretation of details, and no noticeable pixels in the near-view, significantly better than the 1080p model.
Grayscale test
Since the screen shot has undergone necessary software processing and is affected by the actual effects of the netizens' displays, the screen finally displayed on the screen will be different from the actual effect of the TV. Therefore, the actual effect is based on the author's text description. The digital camera I used was a Canon 7D with a Canon EF-S 18-200mm f/3.5-5.6IS.
On the gray-scale screen, the Sony KD-55X9000A is very clear in the dark parts 0, 1 and bright parts 14 and 15 in the dark part, which are difficult to represent.
In the black level display, from the Tokyo Tower in the darkness, it can be seen that the Sony KD-55X9000A has the dark details in place and the black sinking ability is excellent.
In black and white contrasts, black clothes on a black background and white clothes are easy to distinguish on a white background, and overall grayscale performance is at the top level of current liquid crystal products.
Color performance test
In order to make everyone see the performance of Sony KD-55X9000A in various colors more clearly, the author chose a screen containing a variety of colors of wool balls. From the screen shots, it can be seen that Sony KD-55X9000A performed well. There is only a slight stickiness in red and dividends.
For the color performance of the TV, the color that is most difficult to accurately display is golden yellow. During the testing process, the author selected a variety of color wool ball, Sony KD-55X9000A for light blue, pink, golden yellow have a better performance, color accuracy, lines are also relatively clear.
Two girls with red, white, and yellow roses hold the color of the girl's face close to reality, but the brightness of the yellow rose is too high. Perhaps this is closely related to Terri's charm display technology.
Dynamic picture test
In the Montionflow option, the X9000A provides standards, smoothness, clarity, clarity +, and pulse for selection, where the dynamic performance of the pulse is the best, but there is a loss of brightness and flicker, similar to the plasma visual experience.
As a flagship product, the X9000A offers a variety of options in terms of double speed. The best dynamic situation is in the pulse mode, but the brightness is darker and the flicker is more obvious. The user can set it according to personal preference.
LED dynamic control / black correction test
The Sony X9000A offers a wide range of picture quality adjustment options. In advanced options, there are various high-end settings such as LED dynamic control, black correction, gamma correction, and skin color correction.
In practical trials, the X9000A's local light control adjustments show strong strengths. For example, in the LED dynamic control, the screens displayed by the “Off†and “Standard†are quite different. After the black correction is turned on, the dark part is turned on. The details are also significantly better, and these fine adjustments are important for the quality control of the picture.
Menu interface layout
Compared with the past, the Sony X9000A's menu interface has changed, the main menu options have increased the icon display, become more intuitive, beautiful, and vertical, horizontal alternate cross-shaped operation mode, it is still very simple, rapid response during operation .

The subtle menu is still the simple way of the past
Application interface
In today's hot smart TV background, many manufacturers have made the TV interface beautiful and stylish, and Sony's new products this year have also changed, but by comparison, Sony still looks more conservative.
