Sony Z9D Series TV: Better HDR display

Although Sony recently introduced new BRAVIA OLED A1E TV series and other BRAVIA regular updates at CES 2017, Sony did not include the Z9D series, the protagonist of this experience. As the flagship series in Sony TV, Z9D series uses Sony's best technology in many aspects, including Backlight Master Drive (Dynamic Backlight System - Master Edition), Super bit mappingTM 4KHDR, 4K HDR Processor X1TM Extreme (4K HDR Image processing chip X1 Advanced) and Object-based HDR remaster are the biggest advantages.

For a television, we first understand what it looks like. Since it is a flagship, the Z9D can't lose naturally on face value. The atmosphere is the first impression it wants to give us. The 65-inch is the smallest of the Sony Z9Ds, with 75-inch and 100-inch versions up, and the 100-inch version has its own floor stand. The evaluation model we received this time is the Z9D 65-inch version, which belongs to the “mini” version of the Z9D series, but even so, we can still feel its weight and texture when it is actually installed.

Speaking of this, in fact, the installation of the Z9D series TV is still very simple. In addition to the TV main body, there are three larger components for the TV base. Just install the TV unit according to the shape and screw it on. The other components are basically “shadow boards” on the back of the TV to cover various interfaces on the back and ensure visual uniformity while reducing dust.

Speaking of the interface, Sony Z9D series TV has a very rich interface, as shown above, the left side is not frequently replaced line access, such as three HDMI interfaces, a cable signal interface, component AV input, the right side of a vertical column It is an easy and easy to replace interface, including three USB interfaces (including a high-speed interface), audio interface, an HDMI interface, video/audio input interface, digital audio output interface, remote expander interface, and LAN cable interface.

Having said this, I think the traditional TV manufacturers are very considerate in this respect. Apart from being compatible with older audio-visual equipment, it is also convenient for users to build large-scale home theaters. In order to prevent the failure or loss of the remote control, the Sony Z9D series TV also has three physical buttons on the right side of the back panel for operation.

The main body of the Sony Z9D series TV is actually somewhat thick compared with the current mainstream TV, but fortunately, Sony will design a lot of arcs on the back, making it not light, but it is still at least elegant, but when After you understand its strong power, its "thickness" seems to have become acceptable again.

The base of this "Zi" font is more insightful. I personally feel it is very good-looking, and the support effect on TV is still quite good. There is less occurrence of shaking, if the daily is the placement of the Sony Z9D series TV. In the TV cabinet, this is more important.

The bottom of the front screen is the power indicator. When the TV is turned on, a white band of light will appear, familiar with the Sony TV design. From the above two figures, the tails can also see that although the Sony Z9D 65-inch TV is already on, the black part of the screen is already very pure. We must simply chat, as mentioned at the beginning of the article. Those technologies are.

Backlight Master Drive, the Chinese name "dynamic backlight system - Master Edition", is a technology that Sony excavated in LCD technology. The most common backlight control technology that has emerged at present is the area backlight control technology. By dividing the screen into several light control areas, the backlight brightness in different areas is adjusted, but if the light source in the screen is small, there may be a light source. The light control area where it is located is brighter overall.

Sony's dynamic backlight system - Master Edition, is an independent light control for each LED, so it can be based on the shape of the light source to carry out centralized control and adjustment, there will be no bright lights on a region is bright, this technology in addition Separately controlling the light source also actually enhances the contrast, because in places where it does not emit light, independent light control can turn off the backlight or adjust to the minimum brightness. This is not comparable to the OLED's inherent black purity, but it is better than Most of the LCD screens on the market have been better.

The Dynamic Backlight System - Master Edition, in combination with the Object-based HDR remaster HDR, is a dynamic item-by-item reshaping technology that brings dramatic improvements in HDR display performance. The dynamic item-by-item reshaping technology can detect and optimize the color and contrast of each object on the screen, not just the entire screen. Therefore, the light and dark contrast and light transition of different objects in the screen will become very natural and three-dimensional. . It should be noted that this technology is not available on the X93D/X94D series televisions of the same period, and it also allows Sony Z9D series TVs to have better HDR display performance than the X93D/X94D series televisions.

In addition to having excellent HDR display effects, it is naturally not enough. The Super bit mappingTM 4K HDR technology has emerged. I believe there are many tails watching some sunsets or sunrises. They will see a circle of ribbons on the screen, or a fault between different blues in the blue sky image, which is mainly due to the color. The transition between the two is not natural enough. Super bit mappingTM 4K HDR technology uses frame-by-frame scanning to perform 14-bit smooth gradients on the colors in the picture to optimize the color gamut, make the colors look more integrated, and make the transition more natural.

The above three technologies actually require the support of the 4K HDR Processor X1TM Extreme, which is an advanced version of the 4K HDR image processing chip X1. This generation of image processing chips can achieve 1.4 times the real-time processing speed of the 4K HDR image processing chip X1, and it is no wonder that it is called the “Extreme Advanced Version”. This powerful real-time processing capability also enables it to realize the dynamic motion of the MotionflowTM XR 1440, which enables it to cope with large-scale scenes in the face of action movies and screens. In contrast, the X93D/X94D's MotionflowTM XR can only reach 960.

All in all, the Sony Z9D series TV has a very good HDR display effect. At the same time, the control of brightness and dynamic picture are also better than other TV products. Of course, new products released on CES 2017 need to be watched again. There is no doubt that this may be the best Sony TV with the best overall hardware quality.

In terms of hardware technology, there is no need to question the strength of the Sony Z9D series TV. In terms of system and video resources, Sony is also constantly working hard. At present, the Sony Z9D series TV is equipped with an Android 6.0 system. The style is partial to the original, and fluency is still OK. In terms of movie and TV resources, it cooperates with Hua Digital TV. However, if you really want to enjoy the television resources of China TV, you are better advised to open a member. Of course, you can also watch other resources by installing other movie and television applications.

When it comes to television, many manufacturers are talking about 4K, talking about HDR, and talking about resources. Like the international brand manufacturers in the current integration of domestic resources is not very good, but generally have a strong hardware strength, such as this Sony Z9D series TV, multiple excellent technical blessing, of course, the price is not cheap, 65-inch official price It is 32999 yuan. In addition to 4K and HDR, many domestic manufacturers do not delve into the details of their doors. Of course, their video resources and systems are very good. For me, it may be more inclined to buy TVs from international brand manufacturers and then use them with TV boxes from domestic brands.

Nowadays, Sony is returning to the embrace of OLED TV and launching the BRAVIA OLED A1E series TV. The Z series TVs that will launch OLED screens will not be excluded in the future. Will more black technology be born at that time? let us wait and see.
